Features & Specifications

New improved we dim the blue led indicator light so it is not too bright at night. Speaker selector switches allow you to connect multiple pairs of speakers to your stereo receiver or amplifier. The ATM 7-Zone Speaker Selector with Remote Control can control up to seven pairs of speakers so you can listen to music in multiple rooms simultaneously.

ATM 7-Zone Speaker Selector includes an IR remote control. With a backup memory function and a 10-meter remote operating distance, this may be the perfect solution for your needs. Also you can easily program the remote control to any of your favorite universal remote control with the factory code we provide.


Other Product Info

While the speaker selector concept has been around for decades, they generally require you to either walk to the selector in each zone to turn the speakers on or off. The IR remote(line of site to the speaker selector is required) control lets you select your speakers with ease.

March 26, 2019
My inquiry is very simple but I need assurances I can accomplish what I think i can. I want to run 2 sets of speakers (not at the same time) the first set are simple KEF LS50's with a single pair of binding posts. The second pair of speakers KEF Q750's with 2 pair of binding posts. My amp is the Audiolab 8300A which has 2 pair output binding terminals per channel ( 8 in total ) Can I bi-wire my second set of speakers through this device?
1 Answer
Hi Norm: I looked at both the KEF LS50 with a single pair of binding posts. The latest KEF Q750 also features a single pair of binding posts. You might have an older version with dual binding posts. Note, the ATM7 features two inputs, to seven outputs or seven inputs to two outputs. The problem is the two inputs/outputs are Zone A or Zone B. Either one or the other both not both together. You could connect the AudioLab to Zone A (from Speaker A) and wire the KEF LS50 to Zone 1 and then KEF Q750 to Zone 2 to the first set of binding posts and the Zone 3 connected to the second set of Binding Posts. That would allow you to BiWire the KEF Q750. That would still be dual mono from the AudioLab 8300A. To Bi-wire the KEF Q750 you need to enable the Mult Zone button (which applies to the seven outputs only). I hope that helps TL/5473

February 21, 2019
Hi, We have a nine-zone system set up in our home, each zone having one pair of in-ceiling speakers. Each room has a volume control knob for its pair of speakers. The speakers are rated to 40W (RMS) 60W(Max), and 8 ohms. Currently, we have a Denon DRA 685 amplifier and two Russound SS-6 selectors. When we run two or more pairs of the speakers (one speaker set upstairs and one on the main level) at the same time, the amplifier switches to a protection mode, which I assume is an overload protection mechanism. We would like to switch to a speaker selector with remote control, just for the added convenience, but thought we should also look into upgrading the amplifier to run multiple pairs of speakers at the same time without having the amplifier switch off. We welcome suggestions for an amplifier and speaker selector. Regarding the amplifier, we would like an amplifier that has Bluetooth and Wi-Fi compatibility, again, just for the added convenience.
1 Answer
Hi Nabil: The first question, are your nine Volume Controls (one per each set of speakers) all Impedance Matching Volume Controls. And if so what are the settings for each Volume Control. Let us assume you have six pair of speakers on one of the Russound Speaker Selectors and three pairs on the second Speaker Selector. Technically all the Volume Controls connected to the first Speaker Selector all should have an impedance setting of 8X. The other three wired to the second Speaker Selector should be 4X at a minimum or also 8X worse case. Again I am assuming you have one Speaker Selector connected to Speaker A output and the other wired to Speaker B. Now here is a big question, on the Russound Speaker Selectors there is a switch on the top right corner of the back panel labeled Impedance and there are two choices; Bypass and In. The switch should on Bypass for both Speaker Selector boxes. There should only be one solution for Impedance Matching in your setup. That is the proper way to set it up for your application (based upon your Volume Controls being Impedance Matching). The Denon should have no problem powering one, two, three or even all the speakers at once with the proper setup. The ATM7 will work but only if you have Impedance Matching Volume Controls since there is no internal protection circuitry. Lets first determine if you have the proper setup then decide if you want to replace one of the Russound Selectors with an ATM7. Please contact me and let me know if this information has been helpful. If so we can then discuss your other question regarding Bluetooth and WiFi. TL/5423

Hi- Does the remote work through walls?
1 Answer
Hi Doug: The remote is an IR based remote versus RF (Radio Frequency). There is an IR Sensor on the faceplate of the ATM7. The Sensor needs to see the Remote control when you are pushing buttons to issue a command. (know as "Line of Sight"). You can add an IR Receiver Kit where you are adding a receiver that can be wired to another room and operate the IR remote control through (hard wired) a remote IR Receiver sensor. We sell the IR Remote kits as well. TL/5307

Also I'm assuming I would need to connect a sound source to this unit. what you guys recommend so I can control using my smartphone or even a tablet? thanks
1 Answer
HI Gus: The ATM7 will work for your application. You already have your six zones covered including speakers and Impedance Matching Volume Controls> The ATM7 will help you organize your wiring which should be home run back to a central location. You will need an amplifier like our AMP200 and the Pre-One preamplifier. At that point, you will need to decide what source you want to add. There are also some choices for you to pick from that will provide streaming content that you will be able to control with an app on any number of devices including your Smartphone or Tablet. Check out the SONOS Connect, AMAZON Alexa, Any number of Bluetooth dongles (online) or something like the Chromecast Audio. With the Pre-One you can connect a number of these and other older components like a turntable, CD player, DVD player or even an old laptop. Please let me kno=w if you need additional help; TL/5206

Hi, is it possible to connect three or more amplifiers to two pairs of loudspeakers? Thank you. Paolo Marcellini
1 Answer
Hi Paolo: The ATM7 is a 7 zone speaker selector connected to two sources. It has a Master Source A or B switch. You can only play one source up to 7 zones. It is bi-directional, so you can connect up to 7 amplifiers and drive two pairs of speakers, but the A/ B source switch is limited to playing zone 1 (source A) or Zone 2 (source B). Note there is no protection (Impedance Matching capability) for the 7 zones but is not an issue when connecting the two speakers (A/B) and up to 7 amps (you can only select one amp to play at a time (the ATM 7 does not mix the signals). I hope that helps. The ATM7 also features an IR Remote control. TL/5187

Hi I am running 2 Monoblocks and would like the ability to switch between 2 sets of speakers . One set are my main SVS floor standing speakers and one set are book shelf speakers with banana plug connectors. How can I do this?
1 Answer
Hi Tim: I am assuming you are looking at the ATM7 for its remote control capability. There is no problem connecting two speakers to the two mono blocks. You can even run both pair of speakers at the same time assuming you Mono blocks have no problem seeing 4 ohm load. Check to see what you speakers are rated at 8 or 4 ohm. Note there is no internal protection with the ATM7 so you would not be able to run a third pair of speakers (The ATM 7 has 7 zones total.) with the first two without adding Impedance Matching Volume Controls on all pairs of speakers. So yes you can run both pair of speakers (as long as they are 8 ohm) at the same time with no problem. Good luck: TL/4816

Hello, I want to have options for activating a pair (front L&R, rear L&R) of ATMOS in-ceiling speakers depending upon where I am sitting in my 3 row theater seating. The source is the ANTHEM 1120 receiver (see first image) that outputs front L&R and rear L&R 'height speakers'. Those would be switched as depicted in the second image.. Important must-haves: 1) No degradation at all of the sound from the ANTHEM to the speakers. 2) IR remote control, programmed into my URC universal remote, so that I can select the active pair of height speakers from my theater seats. Will the ATM7 do the job? Please don't hesitate to ask questions. Thank you.
1 Answer
Hi Lew: Your images did not come through (please try sending to Are you trying to control the front height and rear speakers so you can turn front on only, or Rear on only or have both play together? The ATM has dual source input so you can hook up front height to source A and Rear Height to Source B. And you can pick either A or B to play but not both at once. We have dual source selectors with A/B switch per zone but these are manual switchers with no remote control (IR, RF or Wi-Fi connections). So the ATM would not work for your application. TL/4770

Howdy, the unit does not have volume control, does that mean whatever the volume comes from the receive that is what gets passed through? Or this unit somehow "generates" (for a lack of a better term) its own level? Thanks!
1 Answer
Hi Pavel: This is a totally passive device like most speaker selectors that do not have internal volume controls. The volume levels are controlled by the input Receiver, Integrated Amplifier or Source through an independent amplifier. We recommend adding impedance matching Volume Controls if you are planning to connect multiple speakers and play more than two pair at a time. It does have a power supply but just to power the LED's and IR remote sensor. TL/4760

Does this unit color the sound at all? I need something transparent as I'm looking for something that I can use in a recording studio to switch between unpowered monitors. I don't want the speaker selector to change the sound of the amp/speaker combination in any way whatsoever. All are powered by a Yamaha P2075 amp. I don't plan on running more than one set of monitors at a time so impedance protection isn't an issue. Is there a way on the remote to make sure that I don't accidentally activate more than one set at a time? Thanks much!
1 Answer
HI Dave: There is nothing in the signal path that would or should add any coloration. The fact it does not have any internal protection guarantees that. Not sure about the remote. The buttons are fairly close and do not have LED's on the remote to indicate what you have selected. Those LED's are on the box itself. The Yamaha appears to be a High current amplifier as well.

Hello, Have you heard of a universal remote that your ATM-7 speaker selector will work with? Thanks! Tom
1 Answer
Hi Tom: If you have the current remote that comes with the ATM7 you should be able to use any Universal Remote that has Learning capability. So as long as you have the current Remote Control to interface with the Universal Remote that should work. The problem arises when you have lost the ATM-7 remote than you need the Head Code and possibly the Hex codes which pertain to the actual buttons. We will post our findings as soon as we clarify with our Factory Engineers. TL/3679

i see that there is not a ON/OFF for the remote. Wonder if there is a IR code out there for it from the manufacture. I was thinking that if your AMP has a switched outlet that your could control it that way?? Anyone use it with a URC remote?
1 Answer
Hi James: The ATM7 does not have a 12 volt trigger that would be needed to connect directly to an Amplifier like our AMP200 or multi-channel amp the MX1260. It does have an IR Receiver input so you can hard wire a IR Receiver to it. We are attempting to get the actual code from the Factory, but you should be able to learn the code form the existing remote using any Universal Remote Like URC. We will post the code once we get it on the site. TL/3111

Hi I would like to manage 2 paires of speakers from 2 different amplifiers (one from HiFi and one from Home Cinema) What kind of product can you propose? Thank you Vincent
1 Answer
HI Vincent: If you need to operate both amplifiers at once you will want to check out either our SSVC2 2 zone speaker selector with 2 internal Volume Controls or our DSM4 a 4 zone speaker selector both which feature independent source A or B switching per each zone. So you can play A on both pair of speakers or Source B on both sets of speakers. Plus you can play source A on one pair while listening to source B on on the second pair of speakers. The DSM4 will allow you to expand to 4 zones and add optional external volume controls for each pair of speakers for the best impedance matching protection. The DSM4 has internal protection but when enabled it cuts the power handling in half from 140 watts down to 70W. There is also the SSVC4 which is 4 zone , 2 source and includes four internal impedance matching volume controls. Good luck TL/4581

I recently purchased an OSD ATM-7 to replace my Russound PRO-VC 6.1 as I want the convenience of remote operation for my whole-home speaker set-up. I just realized that the ATM-7 does not have impedance matching, and as we do not have volume controls installed for our speakers, I wanted to make sure that I don't overload my system with the ATM-7 instead of the aRussound. My speaker installation includes 5 pairs of in-ceiling Tannoy CMS50 ICT or CMS50T ICT (not sure which one). The power handling is rated at 50W and the nominal impedance is 6 ohms (nominal) / 4 ohms (minimum). My amp is an ONKYO TX-NR545 and doesn't seem to have any issues powering my 5 pairs of speakers in Zone 2 with the Russound (we've had this set up for serveral years). Here are the specs from the manual: Rated Output Power (North American) With 8 ohm loads, both channels driven, from 20-20,000 Hz; rated 65 watts per channel minimum RMS power, with no more than 0.7% total harmonic distortion from 250 milliwatts to rated output.

Hi Lesley: Based upon what you have described I not sure if the ATM7 will work for your application. You do not mention using an external amplifer with the Russound Speaker Selector which you had connected to Zone 2. I am assuming you have it connected to the ZONE 2 speaker level output (channel 6 & 7). We usually recommend an external amplifier especially when you are connecting multiple pairs of speakers to zone 2. THe Russound aslo has a very effective internal Autoformer with selectable settings 1 to 12 pair of speakers. Unforturnetly the ATM 7 has virtually no protection. and you had already mention be unable to add impedance matching Volume Controls after the fact. Add to that your speakers are rated at 6 ohm versus 8 ohm which puts more of a strain on the system. The one possibility you might be able to add one of our High Current Amplifers like the AMP300 which would allow you to play two pair of speakers (three would be pushing it) at a time. You would connect the AMP to the Zone 2 Pre amp output. Please let me know what you think TL/4579

Could this unit be wired in reverse? Assuming it is passive, right? Could one hook up 7 amps or receivers to the speaker inputs and one pair of speakers to the amp inputs? volume controls can just be wide open since only one amp or receiver is being utilized at a time. This would allow a person with 7 different amps to compare and enjoy through his favorite pair of speakers if I'm not mistaken. I have one (another brand hooked up this way and it's awesome except for the cheesy spring connector terminals. The ATM7 has the banana plug connectors I need.

I'm not too familiar with audio equipment, so please be patient. I am wanting to replace my current Russound speaker selector with this one, because the Russound doesn't isn't remote controlled. I currently can just tell Alexa to connect to my AVR and play whatever throughout my home. She can also change from the AVR Main Zone to Zone 2, change the source, and change the volume. What she can't do currently is select which speakers to play from. I have to manually go into our library and change that one thing. It's no big deal, but it's one of those things where having to go do that one thing makes having the other conveniences sort of moot. So, my question is about the note above Note. Use impedance matching volume controls with this unit." Is this something I need to worry about? We do not have in-wall volume control. I wish we could control each room's volume, but we don't currently and it's not a big deal. Sound comes from the selected source to the avr to the amp to the speaker selector through the walls to the speakers. Thanks
1 Answer
Hi Dax: There is an issue withe ATM7 not having internal impedance protection in case you want to listen to more than two pair of speakers at a time. So we recommend having to use the Impedance Matching Volume Controls to make sure the amp/receiver does not see a impedance load less than 4 ohms.Most Receivers and Amps want to see a 8/16 ohms load. It is not a big problem if you are using a High Current amplifier like our AMP200 and AMP300. but their limit is between 3 and 4 pair. TL/4459

Problem in operating the OSD-ATM7. When I turn on the OSD ATM-7 and then click on the "zone out / in Selector" 1,2,3 ... ..7 , after 30 seconds to up to 2 minutes, you hear a relay click and the OSD ATM-7 turns off the respective speakers , Also the yellow led goes out. This does not change automatically, therefore you have to press manually the appropriate selector button.If you turn the device off and on again, it will remember the last setting and will function up to 2 minutes. If I use "Multi Zone In / Out", I can turn on multiple speakers at a time (1 -7), and what happens than is actually the same, so after a maximum of 2 minutes, the multiple speakers with corresponding yellow LEDs will turn off. If you do it the other way around, so "IN / OUT Mode" changes, you see exactly the same mistake. Finally, I disconnected all cabling, so both the inputs and outputs and the OSD ATM-7 turned on, and after 2 minutes the speakers 1 - 7 with the yellow LEDs are also released.There I love the OSD to operate I hereby ask you, ca you give me an answer what the problem may be.

does thie atm7 conects directly in the bose receiver in the auxiliary audio input jacket?
1 Answer
HI Javier: The ATM 7 has only speaker level ( High level) inputs and outputs. It has to connect to either Speaker A or Speaker B of the BOSE amplifier. You also have to make sure you utilize Impedance matching Volume Controls for each speaker that you connect to the ATM7. The Speaker Selector has no internal Impedance Matching and if you were to connect two pair or more and play at the same time the BOSE Receiver would have issues with the lower impedance. The problem is when the impedance drops the current demand increases and the more current the greater amount of heat is created. If your receiver is only rated at 4 ohms it will not handle the current draw or the excess heat created. TL/4222

from Oklahoma asked:
January 27, 2017
so we moved into a house that has speakers in all rooms. However there are no wall volume controls. I have a Pioneer SC-55 receiver that has 3 zones. Zone 1 = Living room is hooked up, via 5.1 sound. Zone 2 = master bedroom with 2 speakers, and Zone 3 is the patio with 2 speakers. Would I be able to use the ATM7 to split zone 3 to the master bedroom and 5 additional rooms in our house? Since I dont have any impedance matching volume controls can this ATM7 be used safely if I only turn on 1 room at a time off of zone 3? If so how is switching rooms for this unit done? would I first have to turn off one room then turn on the next room? Or can this be setup in a way that when I turn on another room that it automatically turns off the first room, more of like a toggle instead of splitting? Or would it be too easy to forget to turn off one room before turning on another & possibly overload my receiver? Is there a device I can purchase to put in front of (between receiver & ATM7) or after the ATM7 (between ATM7 and each speaker set) so that it will automatically impedance match and not overload the unit if I were to accidentally turn on two rooms at once? so that way I don't have to cut holes in the walls and splice into the wires to install volume knobs? What do you recommend?
1 Answer
HI Steve: The Pioneer Receiver gives you options. The ATM7 will not work for your application since it has no internal protection and you can not add volume controls to do the impedance matching since your system is already wired. You will also need an external amplifier to power your multiple rooms. What I would suggest is adding our OSD AMP200 and either our SSVC6D or TSM8 speaker selector. Connection to the Pioneer would still be a 5.1 system, Zone 2 would be connected to Surround back (A) speaker level to control your master bedroom. Then connect Zone 3 to your pre amp out to the Input #2 of the AMP200 to run your multiple rooms including your Patio. The SSVC6D features internal Impedance matching Volume Controls to handle the protection. Most likely you will never use the volume controls. The best Speaker Selector we have with internal protection is the TSM8 which features selectable protection knob depending on how many speakers you have connected. The speaker level output of the Audio Video Receiver for Zone 2 and like your receiver Zone 3 are meant to control a single pair of speakers (like in your master bedroom). But when you go to multiple speakers you need to go to an external amplifier connected to the dedicated Zone Pre Amp output. We sell hundreds of AMP200/300 for this application along with the best Speaker Selector for the application (that is why we have 13 different speaker selectors to choose from). Good luck TL/4197

I just purchased the ATM7 unit to run 4 zones fed off zone 2 of my Onkyo RZ710. Each zone is a separate room with one pair of speakers on each zone. There is a SVC-100 volume control in each room. Do I set the impedance matching selector to 1 for one pair in each zone or 4 for four pairs total? Does the power draw from the source amp change depending on how many zones are either on or off?
1 Answer
Hi Michael: The SVC-100 impedance matching volume controls should all be set to 4X. so in case you are driving all four zones at the same tome you are protected for worse case scenario. The ATM7 does not provide any internal protection so the SVC-100 are perfect. The only thing I would add is the the Zone 2 output of any of the Audio Video Receivers is not meant to drive multiple speakers like the setup you described. We always recommend adding an external Power Amplifier like our High Current 2 Channel Stereo Power Amplifier the AMP-200. You do not want the internal amplifier with the single internal power supply attempt to drive multiple speakers on top of the 5 or 7 channels of the surround sound. TL/4162

Hi John: The ATM7 is the only IR remote controlled Speaker Selector we have. We do have 12 channel power amp that features both IR and RS232 control. I answered your original question suggesting you switch to a SONOS Connect versus the SONOS Connect AMP and add our OSD AMP200. I would more than happy to explain further. The SONOS is a great choice for your sources but their amplifiers are limited when dealing with lower impedance and multi room setups. Obviously they want you to have dedicated SONOS per each zone. We recommend the SONOS, NUVO wireless and other well respected streaming pre amps to supply the single source to our basic multi room systems. tim TL/4156

I too want to use this with my Sonos Connect:AMP. I only want to switch one pair of speakers at a time. Connect:AMP ----> ATM7 From ATM7, I'd select Office, or Master Bedroom. Would I still need impedance matching volume controls?
1 Answer
Hi John: If you are playing one pair of speakers at a time then you should not have to worry about using the ATM7. I think you need to verify with SONOS on their SONOS Connect Amplifier on whether it is recommended to drive two pair of speakers in parallel (like playing zone 1 and Zone 2 at the same time). Another option is to purchase a SONOS Connect Pre amp and purchase one of our AMP200 High Current Amplifiers along with the ATM7. This amp has no problem driving lower impedance loads. The concern is when you play three zones, each with a pair of 8 ohm speakers, the first two pair bring the load down to 4 ohm, then by adding the third pair at 8 ohm the load drops to 2.6 ohms. The AMP200 is a high current amplifier featuring the design and all discrete components to handle the increased current demand. The ATM7 is rated at 400 watts so the weak link is the Amplifier. The AMP200 weighs 24 pounds due the ample internal heat-sink needed to dissipate the increased heat created by the low impedance loads. The SONOS Connect Amp Manual says nothing about connecting more than a direct pair of speakers. It weighs 5.1 pounds. Part of that is the SONOS Connect Amplifier is a Class D Amplifier that is usually 90% efficient compared the the Class A/B Analog design of the AMP200 which is 50% But the well built amp has more flexibility to work in more demanding applications and is a true audiophile sounding amplifier. Note; the SONOS Connect features all the same Front end functions as the SONOS Connect AMP just with more options for adding more power. Good Luck TL/4155

Hi Danny: We do not offer rack Ears specifically for the ATM7 1.5 RU size. What Rack are you using and do they offer a universal Shelf for components like this without optional Rack ears. Typically the universal shelf's are for either 1.0 RU or 2.0 RU. I looked extensively on line as well. I saw a good selection of Universal shelves at Mid Atlantic Rack accessories.

I'm looking for an A/B speaker selector with remote capabilities (IR preferred), that can take the A/B source to four or more outputs, and A/B source can be selected at the same time on different outputs simultaneously(with volume control preferred, but not necessary). So I can play source A on output one and source B on outputs two, three and four, or other combinations, but A/B can be selected to multiple output simultaneously. Is there something like that?
1 Answer
Hi Roy: We have the ATM7 which IR controlled and up to 7 zone plus dual source, but limited to a single source for all at one time. The SSVC6D is six zone with Dual Source (and built in Volume controls) but no IR and only a single master A/B switch so one source for all not a choice of two. The SSVC4 is a four zone speaker selector with volume controls and Dual source with individual A/B switches one per zone so you can select A or B on all four zones so you can play both sources at the same time. The DSM6 is a six zone speaker selector with no Volume Controls but does have Dual Source with the individual A/B source switch per zone. The DSM4 is the same as the DSM6 but two less zones. That is what I have that is anywhere close. TL/3719

1 Answer
Hello Greg, That is the function of this unit, but it doesn't have any impedance protection, so unless your Sonos amp can run less than an 8ohm load (4ohm - 2ohm) then you would need to run impedance matching volume controls for each set of speakers.

1 Answer
Hi Garrett, You can, but we don't recommend it. This is intended for use with a high-current amplifier such as our AMP300. This unit doesn't have any kind of impedance protection, so it would be very risky running it off your 8ohm receiver. You could run your receiver into our AMP300 and run the ATM-7 off our AMP300 to power your outdoor system.

I currently have two AMP120s connected to Zone 2 on my receiver, running four sets of speakers total. I need to be able to play 2x sets simultaneously maximum. I want to be able to control what zones are on via IR so am looking at the ATM7. I see I can connect both of the AMP 120s to the ATM7 but it looks like only one can be active at time. Is there any way with two amps that I can get two zones of speakers active simultaneously using the ATM7? If not, any other ideas? Thanks and love your products!
1 Answer
Hi Dan: Typically the AMP120 features A and B speaker output but the speaker switches purposely allow you to only have one set of speakers to play at one time. I am assuming you have decent AVR that not only features a zone 2 output but allows you to control the receiver with a universal remote or application that will allow you to use a number of different devices. Also you did not mention that you are using volume controls to help control the impedance. I do have a suggestion using your two AMP120 amplifiers. You should checkout our SSVC4 speaker selector. It features an internal Volume control per zone to control the impedance matching. The SSVC4 also features Dual source selectable by zone so you can listen to two different sources at the same time. Say zone one would be source A and zones 2, 3 and 4 could be playing source B. The way you would configure the AMP120 would be as follows. Connect Zone 2 output of the AVR to the first AMP120 (source A) to the Input 2. Then connect the second AMP120 (source B) from the first AMP120 Line 2 Output to the In-put #2 of the second AMP120.You can then add a second actual source to Line Input #1 of the Second AMP120.. You would then connect the first AMP120 Speaker A to Source A of the SSVC4. The Second AMP120 speaker B Output would be connected to the Source B of the SSVC4. Make sure the first AMP120 has the speaker A button pushed in and AMP120 has speaker Button B pushed in. I can provide you an actual diagram if you want just let me know if you want a further explanation. Good Luck TL/3152

1 Answer
Hi James, It's not recommended as receivers such as yours can typically only run at 8ohms (1 pair of speakers). Running a multi-zone speaker selector will create an unstable load and you run the risk of damaging your receiver. Best to run an AMP300 to the ATM-7.

1 Answer
Hi Joe, The speaker selector require and amp to feed it power. You can run any handheld device such as an iPhone or iPad to the amp, but not directly to the speaker selector, as it is a passive device. The power supply for the speaker selector is only there to power the LED lights. Any speakers will need to be driven by an amp running to the selector.

Ok, I am interested in this selector as it has remote control. It will drive 5 pairs of speakers. My source is the Zone2 out from a surround amp. What AMP would you suggest? The AMP200 or AMP300? I am not looking for wild power. I just want something that can handle the impendance load that could happen if all speakers are turned on. Thank you.
1 Answer
Hi CR, Either the AMP200 or AMP300 will work, but you will have limited volume on the 200, as running 4-5 zones is going to be utilizing all of its power. The AMP300 has some extra juice for you to really get a lot of power with 5 pairs.

I have a Yamaha RX-V677 AV receiver which has the ability to power 2 zones. Can this unit be plugged into the second zone of the receiver to increase the number of zones in my system to 8? Also, I don't understand what volume impedance control is. Is that a problem in the way I am thinking about doing this?
1 Answer
No, you would need a high-current amplifier to run something like the ATM-7. A home theater receiver is only intended to run a pair of speakers off the zone 2. The ATM-7 doesn't have impedance protection which is pretty crucial when running that many speakers/zones, so we highly recommend running our impedance matching volume controls off each zone.

I am interested in your AMP-7 speaker selector. Currently have 5 pairs of speakers wired around my house. I currently use the 2 in the living room ceiling and a pair of outdoor sparkers the most. I currently have a Sony Muti Channel AV receiver (STR-DH540). Can I make this amp work to run 3 pairs of speakers with you selector?
1 Answer
Hi Ryan, This is a great speaker selector, because you get remote control unlike our other speaker selectors. On the other hand, this selector doesn't have impedance protection as our other selectors do, so it's required to use impedance matching volume controls on each zone. I don't believe your receiver will work with this selector, because it's a surround sound 5.2 receiver, so its main purpose is for home theater. If it has a 2nd zone, that zone can probably only handle one pair of speakers. What you would need to run the ATM-7 is the AMP200 or AMP300 depending on the total amount of speakers you want to run eventually. AMP200 can handle up to 4-5 pairs while the AMP300 can handle as many as 10 pairs. Let us know if you have any questions. Thanks. -BM 2580

Hi Dane, Sounds like a nice setup. The ATM-7 can handle a total of 400 watts, so I believe it's 200 per channel.

Hello, My home has 5 pairs of ceiling speakers that are wired without volume controls. The wires all terminate in one location where I will put my amp. I have an old Harmon Kardon AVR 25 II that has 2 separate speaker outputs. I am interested in using the ATM-7 Zone Speaker Selector to power at most 3 pairs of speakers at a time. I really want to use this speaker selector so I can use the remote and control it from my phone (via home automation system I will be able to turn on the amp, speaker selector, then choose the speaker pairs). There are no other speaker selectors that I have seen that can do this. How important are the impedance-matched volume controls? Is there a device I can hook up to the ATM-7 to accomplish this? Thanks, Tom
1 Answer
Hi Tom, It's great that you are interested in the ATM-7, as it is a very useful product. However, I would not advise you to use it in line with a standard receiver, especially a home theater receiver. The reason being that these types of receivers can usually only handle an 8ohm load, which is one pair of speakers. When running 3 pairs of speaker, as you are intending to, that will create a load of just over 2ohms, which a receiver such as yours wouldn't be able to handle. Even if you ran impedance matching volume controls on each of the 3 zones that you plan to use, I don't think it would be safe with that receiver. My recommendation would be to run our AMP200 to the ATM-7 to give it sufficient power. If you run the AMP200, you would not need volume controls. Let us know if that answers your questions. Thanks. -BM 2430

Hi Nathan, This happens to be the only speaker selector that we manufacture that doesn't have built in impedance protection.
