Features & Specifications

Features
• Distributes audio from a receiver or amp to multiple pairs of speakers
• Send one signal to up to four pairs of speakers in different listening zones
• Impedance protection allows a single amplifier to safely power multiple speakers
• Removable input/output connectors allow easy cable termination
• Includes on/off switches for each zone
• Low prolife with beautiful black brushed aluminum finish
• Works with any amplifier or receiver
• Includes a five-year warranty


The ISS4 High Power Speaker Selector is an easy and effective way to distribute music to up to four listening zones (four pairs of speakers) and play any pair, a combination of pairs, or all pairs simultaneously. Easy to connect with a low-profile design that easily fits into a cabinet or equipment rack, the ISS4 speaker selector includes a dual source input so you can choose between two audio sources. Front-panel push buttons let you quickly turn each pair of speakers on or off independently, and die cut labels fit within the recessed area on the buttons for easy labeling of each zone. A passive device that does not require power to operate, the ISS4 also includes impedance-matching circuitry so you can safely drive all four pairs at once without damaging your receiver or amp. Designed with quality in mind, the ISS4 is constructed of 16-gauge steel with a durable black powder coating and gray silk-screening.

Upgraded Input/Output Connectors
The ISS4 is easy to install (even for non-technical types) and accepts up to 14-gauge cable. The European-style input/output connectors are removeable, which gives you better leverage when terminating cable than traditional spring-loaded terminals. This speaker selector takes either four or two conductor speaker wire stripped at the ends that are inserted into the screw-down input/output terminals for a tight fit to ensure the best signal transmission and sound quality possible.


Protecting Valuable Audio Equipment with Impedance Protection
When connecting multiple speakers to a receiver or amplifier, you need to stay above the amp’s minimum load requirements. Going below the impedance rating can overheat or even damage expensive equipment. The ISS4 includes selectable impedance matching protection circuitry that allows a single amplifier to safely power several pairs of speakers. The speaker selector handles 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

Specifications

Other Product Info

The ISS4, ISS6 and ISS8 are low-profile speaker distribution systems with individual on/off selectors for each listening zone which distribute one stereo speaker-level signal to eight, six or four stereo listening zones. The ISS Series also provides manual power protection that is activated from the rear panel.

The manual power protection switch engages 10 ohm /15 watt resistors wired in parallel, three per channel in the ISS8 or two per channel in the ISS6/ISS4 providing higher power handling capability than the competition (able to handle up to 50% more power!) in order to protect your amplifier. All ISS’s are capable of handling 140 watts per channel total input power without the manual protection engaged and 70 watts per channel with the protection engaged.

The better screw in terminals accept up to 14 gauge cable. The ISS’s feature 16 gauge steel construction with our durable black wrinkle powder coating and gray silk-screening. Each unit is provided with an in-depth instruction sheet and die cut labels that fit the recessed area on the buttons for labeling each zone. The 8.5" chassis width of the ISS4 combines with other 8.5" wide OSD Audio components (which will be available in the future) to make a standard 17" wide unit.

July 30, 2017
I'm planning to purchase an Onkyo TX-8140 Stereo receiver. Will it power 4 pairs of your ICE800 Contractor Series 8" In-ceiling speakers through this ISS4 speaker selector? I have been running all four (Most of the time) for last 9 years using a Realistic System 1000 that met an unfortunate end a week ago.
1 Answers
Hi Gregory: Yes this setup will work, just want to make sure you enable protection switch on front panel that is assuming you are not using impedance matching volume controls in each zone. You could also step up to the DSM4 which has protection switch on the back so it is easier not to disable by accident. Also it gives you dual source (a/b switch per zone). So you could expand your system by adding our XMP100 and choosing from many other sources (computer library, Smartphone etc.). Note if you are using Impedance matching Volume Controls already do not use the protection on the IS$ or DSM if you go with that. Note we also offer a Trim-less version of the ICE-800 called the ACE-800. We also have better (ACE-840) and best (ACE-850) available as well. TL/4494

What type of wire connector is needed to connect this unit to the receiver?
1 Answers
Hi Eric: This speaker selector takes either four or two conductor speaker wire stripped at the ends to insert into the screw down input/output terminals. The speaker wire will come from the speaker level outputs of your Amplifier or Stereo Receiver or even a zone 2 output of an AVR (Surround Sound Receiver). We call this a speaker (high) level connection that comes after a signal has been amplified. Versus a signal (low) level pre amplified signal before being amplified. A external amplifier is recommended when connecting multiple channels from a Receiver to a Zone 2 Pre amp output. Most zone 2 speaker level outputs recommend just connecting a single pair of speakers not a speaker selector and 4 or more pair of speakers (speaker selectors come in 2, 4, 6, 8 or 12 channel versions). In those case it is always recommended to add a good external amplifier to handle the load. TL/4107

Hi Jefferey: It depends on where the speaker selector will be located and what other components you are planning to place along with the speaker selector. Obviously being located in Houston you have a long outdoor season, the down side is you climate is very humid most of the year. So it is probably a good idea that the equipment is a cool dry place. Maybe hard to find in South Texas. Good luck TL/4092

Have an older Technics AV Control Receiver with one 8 ohm front speaker output. I want to split speaker output occasionally to 2 in ceiling speakers (unknown brand and type) and 2 Bose 161 speakers. Will this splitter handle that or will the receiver be able to handle it
1 Answers
Hi Clancy: Yes this speaker selector would work but checkout the SSVC2 Speaker Selector featuring internal Impedance Matching Volume Controls plus dual source. You would be able to play both pair at the same time or you could expand your system by adding a small amplifier like our AMP120 and you could connect a iPhone or iPod and play that for your outside speakers while your inside speakers were playing surround sound. Or you could play both outdoor and the two front speakers form the iPod/iPhone. If you need further explanation, please contact me at tim@osdaudio.com TL/3983

January 29, 2016
I have a Onkyo-8020 receiver. It has a speaker A and B button. I want to run two 8 ohm speakers and a 6 ohm pair. Is it safe to run the 8 ohm speakers on the "A" output and the 6 ohm speakers on the "B" output or can I should I use the speaker selector switch and run it off output "A"? Thank you.
1 Answers
Hi Don: The Onkyo claims to have all discrete components and High Current Audio section. Based upon that you should be able to connect the two 8 ohm speakers on speaker A and then the 6 ohm speaker on Speaker B. I would feel more comfortable if they all were 8 ohm. By adding a speaker selector by itself with out adding impedance matching Volume Controls would not be the answer. The ISS4 has internal protection that cuts the power handling in half. We try recommending Impedance matching Volume Controls because they do a better job of actually impedance matching to the Receiver. The one thing about the Japanese Amplifiers is they usually have pretty good protection that kicks in a relay shutting it down rather than allowing any damage. I would try wiring as you said and try playing both A & B at the same time at moderate levels and then see if the Receiver gets hot to the touch or maybe shuts off. Note: Checkout page 13 in the owners manual, setting up the speaker impedance. In your case I think you will want to set it to 4 ohm (vs the factory default of 6 ohm) I might check with Onkyo to see what they say. Good Luck TL/3683

I have an ONKYO TX-NR609 amp/receiver and am planning to hook up zone 2 to the ISS4 speaker selector to run two sets of outdoor speakers (RS670 rock speakers). My amp says Speaker Impedance 6 to 16 ohms. So does that mean I can run both sets of speakers without any impedance protection?
1 Answers
Hi Brad, It wouldn't be safe to run anything more than 1 speaker per output on your receiver. That type of receiver isn't intended to power multiple speakers off each output. Running 2 pairs would create a 4ohm load which would be unstable for your receiver. It may be a good idea to get yourself an amp to pair with your receiver that has enough power to run multiple speakers. Check out our AMP200!

Thinking about buying the OSD-ISS4 speaker selector. I'm currently using an Onkyo receiver model HT-RC460. I have 2 pair of speakers. OSD AP650 and Klipsch AW-400. Would I have to engage the speaker protection to use both sets at the same time? I normally use one set at a time but you never know.
1 Answers
Hi George, If you only have one zone active at a time, you should be okay with the impedance off, but it's hard to say since I'm not familiar with your receiver. I will say that typically receivers aren't intended to run more than a pair of 8ohm speakers, so it could be risky if you run both sets at the same time.

I'm a little cofused exactly how spliters work and effect the amp. Can you please help me? If I have a 300 watt per channel amp and hook it to a 4 speaker spliter how does it effect the power? Would the amps power be distributed equally across all zones or would it be divided up amongst the 4 zones. You need to make sure the speaker selector can handle that much power. 300wpc is a lot of wattage!

Hi Harold, The amp would still send out 300wpc into the selector and the selector would divide the power equally amongst the zones

When do I need to use impedance protection? I have 2 pairs of speakers hooked up and only plan on ever using 1 pair at a time, never both pairs at the same time. Do I need to enable the impedance protection even when I am only using one pair?
1 Answers
Alex, That really depends on the type of amp/receiver you are using in line with it. If it's an 8ohm - 4ohm amp then you shouldn't have any trouble running it with the impedance protection disabled. The idea is that with two pairs of 8ohm speakers on the same load, the amp is going to see a 4ohm load. If your amp/receiver can only handle 8ohms and not 4ohms, then it may not be safe. Let us know what amp or receiver you will be using. Thanks! BM 2623

I have a samsung surround system that runs on 3ohms. I have just added a Polk psw505 that runs on 8 ohms. I am buying this selector to run speakers to my patio but would the impendence protection on this selector protect my subwoofer as well? I am planning the purchase of a new receiver to replace the samsung unit in the next few months but am looking for added protection until then.thanks for any help you could provide.
1 Answers
Hi Paul, Thanks for the question. The thing about running a powered subwoofer like that via speaker level inputs as opposed to line level inputs (RCA), is you won't get nearly as good quality sound. Theoretically you would probably get a signal through the selector and over to the subwoofer, but on top of the already degraded quality of the speaker level, you're adding an extra component (ISS4) between the source/sub which would further degrade the quality of the signal going to the subwoofer. Also, you may want to double check with Samsung to see if you can run a speaker selector safely from that receiver. -BM 2601

I have a denon avr 591 surround which I currently have running a 5.1 boston surround set. I would like to take the back two channels and hook them up to this unit so I can send power out to 4 outdoor speakers. Is this going to work? Thanks.
1 Answers
Hi Tom, It all depends on whether your Denon receiver can handle anything less than an 8ohm load. When you run 2 pairs of speakers you will drop it to a 4ohm load and if that receiver can't handle it, you could cause some damage. I would advise you to speak with someone at Denon to see if that is safe to do with their receiver, If not, you can run an external amp from the receiver to run the outdoor speakers.

I have this 4 zone selector with 4 zones in my whole house system. However, I have 2 pair of speakers on one of my zones and 1 pair and an additional rock speaker for my outside zone. Total number of speakers is 11. 1 zone has 4 speakers, one has 3, and the other two zones have 1 pair each. This selector simply can't handle all these speakers I don't think. It will cut off the music if I have all the zones on at once. I turned off the protector and it started smoking. I am using the amp that is sold on this website for a 4 zone system in case you need to know that. I guess I am wondering what I need to buy to make the set up I have work. Rewiring is not an option.
1 Answers
Hi Steven: What happened to the four SVC-100 volume Controls you purchased? They should be used for the basic protection of your system including the ISS4. Based upon speakers connected you should have each volume controls set to 8x and then make sure the ISS4's protection switch is turned off (disabled). If you left the Volume control settings to 1/2x and then tried to protect the system with the switch on the ISS4 then it became a big fuse that was ready to blow. Your amplifier has plenty of horsepower but the power is cut in half when you enable the protection circuit on the ISS4 in conjunction with the SVC-100. You might also want to add a second RS660OM speaker to make two pair of speakers on the outdoor zone. So the question is did you use the Volume Controls in the system and how were they configured. Let us know... TS-2249

August 13, 2013
I am totally confused by your answer to Pascal from the Netherlands which is "Your receiver is designed to drive as many speakers as it has outputs. Therefore, we would not recommend doubling that with a speaker selector". I thought the whole purpose of the speaker selector was to allow you to hook up more pairs of speakers to a receiver that it can handle? I have a receiver that can handle 2 pairs of speakers but we have 4 pair in our house. Please clarify. Thanks.
1 Answers
Hi John: Sorry for the confusion. In the US most people who want to add a speaker selector are trying to do so with a second room output from a Audio/Video 7.1 Receiver which is limited to how many speakers can be driven off off the channels 6 and 7 of a 7 channel amplifier that is sharing a common power supply to power all channels. So that is when we typically recommend going with an additional amplifier. In Pascal's case we should have asked what type of Receiver he was using either a two channel receiver or an AVR. In the case of the two channel he could have used a speaker selector like the ISS4 to drive two, three or four speakers at once. They would just have to make sure the protection switch was enabled (on). Of course that would only be true if you were planning to use just the speaker selector and no Volume Controls. If on the other hand you were to use independent Impedance matching Volume Controls (one control for each zone connected) then the Volume Controls would handle the protection and the Speaker Selector's Protection switch would be disabled (off). This is the better of the two choices allowing the Impedance Matching Volume Controls handle the Protection. The Speaker Selector you will notice in the specs is rated at 70 watts with the protection enabled versus 140 watts when disabled. So better to let the impedance Matching Volume Controls handle the protection. So, I would pose the question to you about what type of Receiver you are planning to drive the multiple pairs of speakers? The Brand, Model and type would be very helpful. TL-2143

1 Answers
Hi Harry, It would be helpful to know the model number of your receiver, how you plan to wire your system and what components you plan to use. The ISS4 speaker selector handles 140 Watts RMS without impedance matching. This means you'll need a volume control on each zone doing the impedance matching. If you do not have volume controls, the ISS4's impedance protection must be activated. This would give you 70W RMS. CL/MA 1802

Would I notice reduction in volume if all 3 ceiling speakers are installed? If it does what should I do? Please advise before I start. Thank you.
1 Answers
Hi Eric, Based upon your application, the ISS4 speaker selector may not be the right choice. We recommend returning the ISS4 for full credit and purchasing the OSD AMP200. This AMP200 would connect directly to your Room 2 pre-amplified output (right and left RCA). Connect two of the three speakers to Speaker A and the third to speaker B. Connect the 12-volt trigger from the Onkyo (labeled Room 2, 12-volt trigger) to turn the Amp on and off automatically. Set the output of the Onkyo Room 2 to variable (page 60 of your owners manual) so the Onkyo receiver controls the volume and balance. The AMP200 is a High Current Amplifier that will have no problem running three stereo outputs (kitchen, dinning and living room area). The amplifier can handle a 2.6-ohm load, which is what you'll have with three 8-ohm stereo speakers connected in parallel. This high current amplifier is more suitable for the quality and level of the Onkyo TX-NR809 versus the compromise you'll make with a basic speaker selector with a protection switch. Regarding your choice to go with a single stereo speaker rather than a stereo pair in your three rooms, is space or accessibility limited? These speakers are typically limited to hallways, bathrooms or even master bedrooms. Check out our MK690TT speaker that features the same trim-less grill design, a dual voice coil for running a summed mono signal and dual tweeters for greater dispersion of the high frequencies. It's similar to the Yamaha speaker but features a more elaborate crossover network and a unique Kevlar cone material. Plus, our speakers feature a special dual application switch that allows them to be connected as a stereo pair where both tweeters are playing (doubling your coverage).

1 Answers
Hi Gerry, Most of the early designs of speaker selectors had some sort of automatic protection in order to work long term. It prevented units from coming back from customers who did not understand the importance of using the protection switch when playing two or more pairs of speakers. I'm not sure you are going to notice a big difference from 3 to 4 zones. You could use independent volume controls for each zone (if your wiring is accessible) or purchase either our AMP200 or AMP300 and connect the three 8-ohm pairs in parallel so you have a 2.6-ohm load. This way you'll get the most out of the amplifier while not cutting half the power by adding the resistors in-line in the speaker selector. It would help to know what speakers are you using, what kind of amplification you have and and how old it is. TL/MA 1452

I am looking for a selector that will handle only 3 sets of speakers.

Is this unit going to make me happy or should I look elsewhere?

Tim: Hi Gerry, The lack of a fourth speaker should have no effect since you have an on/off switch for each zone and would just leave the fourth zone in the off position. Our updated ISS4 also comes with removable input/output connectors that provide improved connectivity. Just remember to keep the protection switch in while you are playing the three pair 24/7. It certainly will be an improvement over your previous selector. TL/MA 1451

Hi. I am using this with zone 2 output of my onkyo 609 for two pair of speakers (bed room and patio). Onkyo says 6 ohm minimum. The speakers are 8 ohm. Is this all right with this set up ? Would it sacrifice any quality, volume etc? Thanks
1 Answers
Hi Win, The Zone 2 you’re referring to is intended for a pair of speakers. Ideally, for 4 more zones you would add an amp like our AMP200. What you could do is hook the ISS4 up with what you have now and see if the Onkyo is giving you enough power and go from there. You may notice when playing more than one pair at a time you have less volume capability. In this case you could add an amp. All the components we sell are 8 ohm so they will work fine with your Onkyo receiver. CL/MA 1303

I have three pair of speakers that I am trying to connect to the Iss4 can you give me some help connectins my speakers
1 Answers
Hi Don: The ISS4 connects to the Receiver/Amplifier with two two conductor cables (right and left, +/-). You start with the connection to the receiver look for speaker A output assuming you are connecting to a two channel stereo receiver. Or if it is a Audio Video Amplifier featuring a second zone output you can connect to that. Then connect to the Right and Left inputs of the ISS4 (color coded Red for + and Black for -). Each pair of speakers will be connected to dedicated zone again matching up the right and left outputs of each zone. Look at our CL3 16/2 speaker wire that comes in a single white jacket with two internal conductors (with red and black jackets). Just make sure you connect the red to the positive input of the speaker and black to the negative input. Do that for Zone 1, Zone 2 and Zone 3. Make sure the protection switch on the front of the ISS4 is enabled (pushed in). You have an on off button for each zone on the front panel of the ISS4 (pushed in is active). Make sure all the equipment is turned off before making and completing all connections. Any problems just contact us again. TL

Hello: I am looking to connect 3 pairs of "Polk Audio RC80i 2-Way In-Ceiling Speakers". Would it be possible with this? 2. I have been recommended to get this "Russound SS-4.2". Instead, I am planning on getting this item. Am I missing anything or will this item suffice what the SS4.2 is supposed to do. TIA! Vinay
1 Answers
871 Hi Vinay, The Russound piece is an excellent unit. It does have a nice feature that has protection for your amplifier/receiver; otherwise they are similar. I am partial to our DSM4 which is the next step up and adds dual source (switchable per zone), a European style removable input/output connector and a brushed aluminum faceplate for cosmetic appeal. All three will take care of your application. TL/MA

Hello, I have a monster of an amplifier (8000 Watts to 8 channels)--can I use this selector? Why isn't there an individual 'in' for every 'out'? Amp details: https://www.pyleaudio.com/sku/PT8000CH/19-Rack-Mount-8000-Watt-8-Channel-StereoMono-Amplifier. Thanks, k
1 Answers
Hi Kevin, This speaker selector is intended for one amp to drive 4 pairs of speakers with a capability of 140 Watts per channel max. Ideally, the ISS4 unit would be used with an amp ranging from 100W – 300W. My recommendation for you would be to use several of our volume controls with on/ off switch - The SVC205 you would give you volume and zone control in each room. It will have an On/ Off switch, check your owners manual for the diagram showing how to use volume controls. The SVC205 will give you the same function as a speaker selector, but the control will be in each room. You will set the impedance matching to 1/2X for each volume control. The on /off capability will allow you to shut off the respective zone at the Volume Control itself. Just turning the VC all the way down does not disconnect. CL/MA

Would I need anything other than a normal amplifier and passive speakers to use this? Would I need impedance matching volume controls, whatever they are?
1 Answers
Harry, The ISS4 already has impedance matching so you can use a resitor based volume control if you would like to add that in. Take a look at the VKR120. CL

2 Answers
Stephen, This speaker selector has Impedance matching. CL
Customer Service - Q&A
on November 29, 2011
I am assuming you have a switch now that separates your zones but with no actual dedicated protection. The ISS4 Speaker Selector has a protection switch on the front that we recommend keeping enabled or in the on position (pushed in) whether you are playing 1, 2, 3 or 4 pairs at a time. The only time you would defeat the switch would be if you were using Impedance Matching Volume Controls, one for each pair of speakers. Having both the protection circuit enabled plus the Impedance Matching Volume Control would cause a conflict with the Amplifier/Receiver

Will this device control speaker pairs that have different impedance levels? I have one pair of speakers that are rated 6 ohms and the other pair is 8 ohms.
1 Answers
That should not be a problem. I am assuming you will be connecting more than these two pairs of speakers to the four zone box. If so, just make sure the internal protection switch is enabled (on). If you are adding impedance-matching volume controls between the box and speakers, then defeat the internal protection. TL/MA

Performs as described
Compact size and has a quality appearance. I have 3 pair of 8ohm indoor ceiling speakers and one pair 4 ohm outdoor speakers connected to a 40 W stereo receiver. Works great for selecting any or all zones. Owned for one month so far ans works fine. Excellent price for product. Shipped quickly.
ProsPrice, size, and easy to use.
ConsWire connections are tiny and not as described in manual. Would be great addition to include a tool (very tiny screwdriver) to make wire connections.

Works as advertised. Good value.
This replaces one I bought from Radio Shack about a dozen years ago and which was becoming squirrelly. Since hooking it up, which was a little fiddly, it works just fine and the little labels that come with it (to identify the speaker zones on the selector buttons) are a nice touch.

Unit is easy to use. The con on this and so many units like is that the wire connection system is flimsy and closely packed. The chance of a short circuit is great if you have even one stand of speaker wire out of place. I have to get my soldering iron and pre-tin them to make sure there is no problem

Great product
I wired my entire ground floor of my house for in ceiling speakers. I purches eight kevlar speakers and two selector switches. Now when I have guests over there is a party in every room. Everything works great and the switches were clearly marked. The package was packed well for shipping. The only flaw was their tracking of my package was no working. I called and they could not tell me where my package was. But, my package did show up on my door step three days later. No harm no foul.
