I currently have an Omage SS-4R which I believe is a resistor based switch. I have an Onkyo TX-NR5009 which was their flagship receiver back in the day and outputs 140wpc. I currently have 4 pair of speakers wired to the switch powered by Zone 3 on the Onkyo. What benefit will I see by getting this switch to replace my resistor based one? (besides the volume controls?)
1 Answer
HI Rob: The Omage SS-4R is similar to our ISS4 which is also resistor based but has manual switch for the protection. We usually recommend adding impedance matching volume controls and bypassing the internal protection. When the protection switch is enabled and signal is diverted through the resistors the power handling is cut in half 140 watts to 70 watts. The SSVC4 has the impedance matching volume controls built in (300 watts peak, 150 watts RMS per each) Not only do they do the heavy lifting (protection) they give you additional control for each zone. Plus you have dual source option per zone between source A and B. There is also a manual on/off switch per zone as well. Good match for the ONKYO Receiver. Usually we recommend adding an external amplifier but the ONKYO typically is a high current amplifier that has the current o handle the application. TL/4862

I need to control 7 zones. Can I daisy chain two SSVC4 selectors in order to do that? Thanks!
1 Answer
Hi Perry: Yes you can use 2 SSVC4 but we have recommended going with either our Powerful High Current AMP200 or AMP300 and running a SSVC4 off each speaker output (A&B). One to speaker A and the other to Speaker B. You can even run two amps and have both amps connecting speaker A and speaker B and use the dual source option selectable per each independent zone. So you connect AMP #1 Speaker A to Source A on first SSVC4, then Speaker B to Source A on the second SSVC4. The second amplifier would connect Speaker A to Source B of the first SSVC4 and then Speaker B to Source B of the second SSVC4. Now you have 8 zones for either the single AMP setup or the two amp dual source setup. TL/4710

I would like to find a speaker selector to power combinations of 4 and 8 ohm speakers using my NAD 218 THX 200W amp. Two questions: 1) Will these selectors handle 4 ohm loads in combination with other speakers if the amplifier is rated to drive 4 ohm loads? 2) It seems that the OSD speaker selectors (and many others) accept 14awg wires or smaller, is there a way to get get larger wires into them? Thanks!
1 Answer
1.) NO, you should never mix impedance. 4 and 8 ohm should be run through separate amplifiers. 2.) Not at this time as there is no benefit when running through a speaker selector box.

I want to use a sonos system - can I use this with the sonos amp?
1 Answer
Hi Vanessa: Yes you can use the SSVC4 with the SONOS Connect Amplifier. The internal Impedance Matching Volume Controls will protect you SONOS from seeing a damaging load. Just connect the SSVC4 to the Speaker Right and Left (+/-) outputs to Source A Right and Left (+/-) inputs. Make sure you use the on/off switches per the respective zone to actually turn the zone on or off and not depend on turning the volume control counter clockwise until the music is in audible for that zone.

Can this be used on a 70v system?
1 Answer
Hi Gerald: The SSVC4 does not work on a 70V system but we are developing a new Mono two zone 70V with thru output so you can daisy chain multiple 2 zone for 2, 4, 6 or even 8 zone. Each channel will have 100 watt mono internal volume control associated with plus a on/off switch per zone. It is probably 60 day s out. In the interim check out our line of MVC 70V mono volume controls featuring a true thru output connection allowing you to daisy chain multiple volume controls while creating independent zones.. In three sizes 100W, 50W and 25W. TL/4208

Can you use 4 ohm speakers with this? if so, is there a special way of wiring them or same as normal?
1 Answer
Hi Brett: Whether you are using a single pair of 4 ohm speakers and (3) 8 ohm speakers or all 4 ohm speakers. you need to calculate the 4 ohm speaker as (2) 8 ohm speakers. So if you have a pair of 4 ohm speakers (counted as 2) and 3 pair of 8 ohm speakers (counted as 3) so 2 + 3 = 5, so the setting would technically be 8X but depending on if you are planning to play all the zones at once or depending what amplifier you are using you can get away with 4X for all. If you are using all 4 ohm speakers so your calculation would be 2 for each pair of 8 ohm speakers so 2 x 4 = 8 so setting on all pins would be 8X. There are 6 pins behind each internal Volume Control. Pin 1-2 = 1X, pin 2-3 = 2x, pin 4-5 = 4X and pin 5-6 = 8X. There is a jumper that connects the two pins at a time. Lastly you wire the 4 ohm speaker exactly the same as the 8 ohm. Good Luck TL/3917

from California asked:
April 29, 2016
Does this switch support stereo speakers for each zone? If I wire zone 2 of my amplifier into the input will i be able to hook up 2 speakers in 4 different locations?
1 Answer
Hi Nathan: Most AVR recommend connecting a single speaker to ZONE 2 or ZONE 3 where applicable. They discourage adding more than one set of speakers, speaker selectors or even impedance matching volume controls to the speaker level ZONE 2 output. The output is for a single 8 ohm pair of speakers and that is it. All channels share a common power supply and all channels recommend a single speaker to it like your right front, center and left front. But most Audio Video Receivers feature a ZONE 2 Pre Amp where they recommend you connect to an external Power Amplifier like our AMP200. You would then connect the SSVC4 which features four internal Impedance Matching Volume Controls each with stereo output and individual On/off switches per zone. It also has dual source with individual a or b switches per zone. The external amp with the SSVC4 is an excellent combination. Good Luck TL/3849

Please let me know what I should set inner switches to for 6 ohm speakers. ALL of my speakers are 6 ohm. Upgrading to Marantz sr7010(has ohm selection for 4, 6, 8) with outlaw 5000 amp for full 7.2.4 atmos and will use ssvc for switching and activating outdoor and front room towers (back/listening room is all ELAC) for all channel stereo 11.2 (Oppo bdp-103d media player) I have read the reviews, q&a's, and manual and notice ya'll have great customer service and answer that question. But didn't see anything about 6 ohm. Looking VERY forward to testing! Haven't done an upgrade like this in years! Wallet keeps reminding me!
1 Answer
Hi Joshua: Technically, when calculating the impedance setting on the Internal Impedance matching Volume Controls you have to base everything on 8 ohms. If you have 4 pairs of 8 ohm speakers you set the jumper to pins 4 and 5 for 4X. If you had 3 pairs of 8 ohm speakers and a single pair of 4 ohm speakers you have to treat the 4 ohm setting as (2) 8 ohm speakers making it appear to be (5) 8 ohm speakers. So the next highest setting is Pins 5 & 6 for 8X. So based upon that if you connect all four zones with 6 ohm speakers (4) x 1.5 or (6) 8 ohm speakers so 8X would be the safe bet. But you are using higher quality components that feature High Current amplification (like our AMP200 and AMP300) which I would recommend setting the pins to 4 & 5 for 4x. Note, I believe the SSVC4 comes from the factory with the jumpers set to pins 2 & 3 for a 2X setting. You will have to remove the cover (making sure nothing is powered up maybe even disconnecting all the input and output connectors) and change all the jumpers to 4X (pins 4&5). It is also a good idea to turn off a zone using the individual zone on/off switch rather than using the volume control to turn the sound down where you can no longer hear the music. I hope that helps TL/3750

1 Answer
Hi Allan, It really depends on your amplifier if it can handle a 4 and/or 8 ohm load. You would want your speakers to match with what your amp can handle. More than likely you'll want to change the impedance for the 4 ohm speakers. CS 3647

I've got an Onkyo TX-NR626 receiver with powered zone 2. I am currently using this to drive a pair of patio speakers (AP65), but would like to expand to another 2 sets as I have a long patio (AP450s, probably). I'm assuming when you split the power so many ways, the power to any one pair decreases, yes? Should I be looking at a standalone amp to feed the SSVC4 from the line out on my receiver? Thanks, Jonathan
1 Answer
Hi Jonathan, Yes it would be a good idea to have a separate amp to use to power your speakers if you are planning to add more to your set up. Using a speaker selector on a receiver could eventually cause some damage to the receiver. Check out our AMP200, that would be a good addition to your setup. CS 3510

January 11, 2015
I have a spare 7.1 receiver which has Spotify Connect and Airplay receiving-capabilities. I am considering using this in order to power onwall and in-ceiling speakers I have in the lounge (2 speakers), the bathroom (2 speakers), kitchen (2 speakers) and bedroom (1 speaker). I was going to buy a selector but I have experimented some with the 7 channel stereo which seems to send L/R to front, rear, side and center speaker (which gets l+r). Would an speaker selector such as the SSVC4 add something to my install? Also is it advisable to put speaker level volume controls between the receiver and speakers or will this disturb the receiver? Down the road I am aiming for a proper multi-room setup but I am waiting for a multi channel amp with spotify connect and airplay capabilities as well as good app control for controlling the zones (most of which my 7 ch receiver has except the individual volume control).
1 Answer
HI Fredric: The SSVC4 would be perfect for your application. The internal volume controls will control the impedance matching needed when connecting more than two pair of speakers to your AVR (Receiver). An added bonus would be if your receiver featured a second zone output. If so this could be connected to the second source input of the SSVC4 (Source B). The L-R from the AVR output would go to Source Input A. This would allow you to play two sources at once at the same time. The speaker selector features a A/B switch for each of the four zones so you could be listening to source A on Zone 1 and 3 while listening to Source B on zone 2 and 4. Check your owners manual to see if it features the second zone out. Note if you do not have the owners manual you can find almost any Owners manual on line. One other point: The SSVC4 also features an on/off switch which you should use when not listening to a particular zone. Turning the Volume Control all the way counterclockwise does not turn the zone off. Good luck, TL/3092

from Roseville, CA asked:
January 9, 2015
Hi, At the heart of my home AV system I run a Denon AVR3802 receiver. It, however, can only source- and volume-control 2 independent zones/rooms, which does not meet my needs of wanting to control 4 independent outdoor listening areas in addition to my living room. I recently inherited a NuVo NV-E6DMS six source, six zone amplifier, however do not have or want to utilize the in-wall individual zone controller keypads this multi-zone amplifier typically is set up with. Is there such a thing as a centralized multi-zone volume controller that would allow me to feed a single source signal to the Novo amplifier and then have that NuVo amplifier send up to 6 zone audio signals to a centralized volume controller which, in turn, would take the individual audio signals, modulate them individually to the desired audio level (incl. "off") and then send the modulated signal to 8-ohm speakers in the various outdoor listening zones I have? Thanks!
1 Answer
HI Holger: First question, does the NUVO NV-E6DMS work? If so it would be ideal for your setup but you will need the control pads to make it work the best. You can find the control Pads on eBay or contact NUVO directly. The unit is probably 6 to 10 years old but still should handle your needs. You would have the option to either utilize the key pads in each room if you have the ability to run Cat5 to each location or you can create a master control panel with all the control panels grouped together in your central location. The NUVO also gives you the ability to add up to 5 additional sources since it has a built in 6 source pre amp This is where you would connect your Denon second zone output. The control pads would allow you to select the different sources attached to the NUVO Amp/Preamp as well as control the volume, bass and treble. I believe there is also a party mode where you can control all your zones from a single control pad. I would love to recommend the SSVC4 but it is only dual source and you would not be taking advantage of all the features of the NUVO. TL/3090

I have a Yamaha RX-V663 - 7-channel Receiver. I currently use the iPod Dock with Polk Audio RTiA7 8ohm speakers in the front speakers A port in my house. I would like to hook up 1 - 3 sets of Yamaha AW390 speakers (6ohm) on my covered porch either at the same time (A&B) or just A or B by themselves. First of all from what I am reading in the receiver manual is that if i want to run ports A & B front speakers at the same time I will have to have all 8ohm speakers and can only run 1 additional pair. Can i use this speaker selector for what I want to do?
1 Answer
Hi Danette, You have the right idea about what the speaker selector does, but your receiver isn't built to handle that type of load. You will need an external amp to run from your receiver to this selector in order to supply enough wattage and handle a 2-4ohm load. Check out our AMP200! BM 2745

I have a Yamaha RX-V390, and I wish to drive sound into two rooms - room One has a single set of speakers and room Two has two sets. Primarily, I want to achieve different volume levels in room One versus Two. I am confused by the wording of the RX-V390 describes front/center/rear capabilities rather than speakers A vs. B. Anyway, is the SSVC4 the right product to pair with this RX-V390 to achieve what I want?
1 Answer
Hi Demeritus, Sorry for the delay. Typically you wouldn't want to run multiple zones off a home theater receiver. This receiver is intended to run a 5.1 surround sound where you have a center speaker, a front left and right speaker, and then a back left and right speaker. If it has the ability to run a zone 2, you would only want to run one pair of speakers on that one zone. If you want to do a 4 zone audio system for music listening, I would recommend getting a stereo receiver or amplifier that isn't for surround sound. Check out the RX5502 or the AMP200. The RX5502 is more affordable, has AM/FM tuning, and has 4 zones so you wouldn't need the SSVC4. The AMP200 would require the SSVC4 if you wanted separate volume control on each zone, but does have much more power and efficiency than the RX5502. Call me with questions. 562-697-2600.

I am looking at a Onkyo TX-NR616 with 7.1. I would like to drive the SSVC4 from the multi zone 2 speaker outlet to 4 pairs of 8ohm speakers. One in the pool area, one on the front porch and 2 pairs in the kitchen/dining room. Not all 4 will be on at the same time, likely 2 maybe 3 sets at once. What would I set the impedance to inside?
1 Answer
Hi Dwayne, Thank you for asking. First, I would like to suggest using a separate amplifier dedicated to the SSVC4, rather than running it off the home theater receiver. The reason being that most receivers can't handle more than an 8ohm load on the zone 2, and usually will advise against running a selector in the owner's manual. Contact Onkyo to make sure. If you can run it off the receiver, you should keep the impedance per all 4 zones at the default 1/2x setting. If you cannot run off the receiver, you can use our AMP200 to run to the SSVC4 at the same settings. Please feel free to call us for more details. 562-697-2600. Thanks! -BM 2235

What size of receiver could I get away with? I have 3 sets of outdoor speakers that I want to connect. Do I need the 7.2 still, or can I get away with a smaller receiver?
1 Answer
Hi Vanessa, Excellent question! If you are going to use the SSVC4 speaker selector, or any speaker selector for that matter, you should use a high powered amplifier that can handle that kind of load. Typically, a standard receiver is only built to handle a pair of 8ohm speakers on each channel. If you haven't purchased a selector yet, you can use the SW-RX5502 4 zone receiver. Now, you can only control A+B and C+D on and off, but not each individually. So, if you need to have individual control on each zone, go with the AMP200 and SSVC4.

My receiver has 2 channels. If I want to use the Speaker Selector to control 3 pair of speakers, what is the best way to connect the receiver and selector?
1 Answer
Rich, First, you want to make sure your receiver can handle a speaker selector. Search the owner's manual for any mention of this or call the manufacturer direct to inquire about that. Typically a standard 8ohm receiver can't handle anything but an 8ohm load, so a selector can potentially cause it to see a lower impedance load and do some damage. If you can't run one of your receiver, you'll need a high current amplifier, something like our AMP200. You simply run the left and right channel from the amp (or receiver if it can handle it) to the input of the speaker selector, like you would a pair of speakers. -BM 2082

1 Answer
Hello, The Zone 2 and Zone 3 outputs are designed for one set of speakers. You can, however, use the 'pre-amp out' into an external amp like our AMP200 to drive a speaker selector. With the AMP200, you won't need to change any jumper settings internally on the SSVC. CL/MA 1864

I have 3 pairs of 8-ohm speakers and one pair of 4-ohm speakers. Will the SSVC4 properly match the different impedance and protect my source amplifiers? I read another post that indicated there are "internal jumpers" that are set at 2x. Would I have to take apart the speaker selector in order to change jumpers? If so, how would I set them so my system is properly balanced?
1 Answer
Hi Scott, Based upon your application, change the settings to 4x internally on all four of the zones. Technically, you would consider a pair of 4-ohm speakers as two 8-ohm speakers so you would have 5 speakers (adding three 8-ohm speakers to the 4-ohm speaker considered two more 8-ohm or five total). Therefore, go to 8x on the safe side. You also need to factor in the receiver or amplifier. An 8x setting would be advised if you are using an amplifier like our AMP120 or connecting to a basic audio/video receiver's second room option to do multiple rooms. A 4x setting would be advised on a high current amplifier like the AMP200 or a top of the line audio/video receiver. Let us know more about what you plan to connect to the SSVC4. TL/MA 1633

I don't quite understand what comes out of the receiver and from where to go into this. Is it out of the receivers native speakers outputs?
1 Answer
Hi Chris, Our speaker selectors are all passive devices which help organize the speaker level outputs from your receiver (an amplified signal). A standard speaker selector features four, six or eight zone connections with a dedicated on/off switch per zone (like our ISS4, 6 or 8). It also features a button labeled for protection to be used in case you are connecting the speakers directly to the speaker selector without impedance-matching volume controls. The step up to the ISS series is the DSSM which operates the same way as the ISS but adds an independent A/B switch per each zone allowing you to select between two different sources. The protection switch operates the same as the ISS series. Now the SSVC series speaker selectors you reference to in your initial question is part of our speaker selectors that feature a dedicated built-in Impedance-matching volume control for each zone.

Dr B
from Georgia asked:
January 3, 2013
I have a Yamaha RX-V2095 AV receiver. I want to add additional speakers, e.g. outdoor speakers, bedroom etc. I am thinking of using the SSVC 4 to control the speakers and volume. I did this before just using one of the speaker output and dividing, I do not think that is best option. There are ways to connect an external amplifier and then a speaker selector. What are the best options here?
1 Answer
Hi Dr. B, A simple recommendation is to go with our AMP200 connected to the Preamp Room 2 output of the Yamaha RX-V2095. Then, add the SSVC4 to the AMP200 to control your four zones. The Yamaha has a dedicated room2 output that allows you to play a different source for your room 2 at the same time you are using the receiver for surround sound. You can connect a single pair of speakers to each zone of the SSVC4 or a single Dual Voice Coil speaker where you have room for a single speaker. We have these available for in-Ceiling (ICE640TT), Rock Speakers (RS850TT) or even Patio versions (AP550TT). You also can connect up to two pair of speakers to a specific zone. The SSVC4 has internal jumpers to make adjustments to the impedance settings depending on how many speakers you connect to it. This will entail removing the cover of the unit and changing the jumpers. Note: The Impedance setting as noted in your attachment only pertains to the speakers you have connected for surround sound. It has no effect on the preamp setting. We would be happy to discuss your overall whole house audio design. Good luck! TL/MA- 1510

December 14, 2012
I am considering the SSVC4 for my set up and want to make sure it will work. I have a 2-zone Onkyo receiver and on zone 2 I have 2 sets of outdoor speakers (in parallel), each with a OVC300 volume control located outside by the speakers. This setup works great. I have great sound from each set of speakers. I now want to connect the zone 2 to a SSVC4, separate each of the outside speaker sets into a separate zone on the SSVC and also connect to 1 of the 2 remaining zones to a set of speakers in another inside room. All speakers are 8 ohm. I would like to keep the outside volume controls. Will this set up work? Can I have the outside volume controls after the SSVC4? Should I keep the volume control at the SSVC4 on max and control the outside speakers' volume with the OVC300? The only set of speakers that I really need the volume control for is the third zone that will power the additional room. If I have only the zone for that room turned on the SSVC4 (the 2 outside zones are turned off), is it passing all the power from the receiver to that room only? Is there a switch on the SSVC4 that adjusts the impedance, just like on the OVC300? what should it be set to? Thanks!
2 Answers
The OVC300 has impedance matching, as well as the SSVC4. However, you do not want both components performing impedance matching. We would not recommend the setup you describe. Your zone 2 is really meant for a pair of speakers, not a speaker selector. We recommend adding an amplifier like our AMP200 with a speaker selector without volume controls, like the DSM4. You would go from your receiver to the amp, then to the speaker selector then to the volume controls and then on to the speakers in that order. CL/MA 1465
Customer Service - Q&A
on December 14, 2012
CL is right. You really need to go to an external amplifier when connecting additional speakers to your second zone. You have done a nice job utilizing the OVC300s to configure your two outdoor speakers. What we suggest is adding an OSDAMP200 then connecting your two outdoor speakers just like you have it now to Speaker A of the AMP. You can then either add the third (inside Zone to Speaker B). Assuming you do not have the ability to connect an external volume control for this new zone, you could add either a SSVC1 or a SSVC2 with potential for a 4th zone. The SSVC speaker selector would be optional and could be added if you feel you would need to use the Volume control. You would have on off buttons for Speaker A and B on the front panel of the AMP200. TL/MA - 1465

from MD asked:
December 9, 2012
This looks like just what I need. But so I understand when I am matching an amp and speakers.... Does the selector split the wattage between channels? So, if say, I use a 100 watt amp and 4 sets of speakers, will each receive 25 watts? AND if I select only one set of speakers and have the other 3 pairs switched off, does the pair that is being used see 25 watts or 100 watts? Or have I got this all wrong? :) I am trying to decide what wattage of speakers would be suited to a given amp wattage... Thanks for any help, Andy
1 Answer
Hi Andy, What you want to look for are speakers similar in power rating and (at a minimum) rated to handle the power of the amplifier (connected to the speaker selector) if they were the only pair connected. If you have an amplifier like our AMP120, which is rated at 50 watts per channel, you need speakers rated at a minimum of 50 watts per channel. There are other factors involved but following this simple rule will have you covered. TL/MA 1456

If I supply this device with 100 W and run 4 pairs of speakers from it the max. power to each pair will be 25W? Or is 'impedance matching' allowing 100W to each pair.?
1 Answer
Hi Brian, We’ll need more information to help you. What component are you using for the 100 watts? Will you use the unused channels of a 7.1 Audio/Video Receiver or a dedicated power amplifier like our AMP120 or High Current Amplifier like the AMP200? The SSVC4 comes from the factory with the internal jumpers set at 2X so it is designed to have a higher output, especially when used in conjunction with our AMP200. The jumpers need to be set to 4x or 8x when used with our AMP120 or with most Audio/Video receivers. With a little information, we can be more helpful. TL/MA - 1405

How do you remove the speaker connector plugs? The instruction page refers to a "captive screw" on each side of the connector. I'm not finding that.
1 Answer
Hi Dennis, The A/B input plug and also Zone1/2 and Zone 3/4 connectors are removable. They are not attached, but the connection is fairly tight. I find pulling on one side then the other while applying constant pressure works best. It is literally just pushed in. You’ll find that when it is removed, it is easier to terminate the wires because you have much better leverage. TL/MA 1318

Connection options to be sure I understand. My receiver has an A/B selector. Please confirm that I can connect this unit to my B speakers coming out of the receiver as 14 gauge speaker wire. The SSVC4 can split this signal into 2 or 4 zones with separate volume controls. If that sounds correct. Given this set up, will I be able to turn my amp volume down (my A speakers) and still crank up my B speakers much louder? Thanks for your help!
1 Answer
Hi Dan, All of our speaker selectors will accept 14 gauge wire. What you're trying to do may be determined by what your receiver can do. Does it allow separate volume control for A and B? I am assuming it does not. Our volume controls are passive devices that allow you to turn down the volume; they do not amplify a signal. You might consider using our SVC300 volume control on the A speakers that you want to turn down. If you tell me more about your application, I can make a more detailed recommendation by knowing more about your system. CL/MA 1294

i have an home theater receiver, what is the best way to connect to this device? front, rear or center outputs?
1 Answer
Hi Chris: Check your owners manual or let me know what make and model Receiver you have. Most will allow you to use it as a 2 channel receiver. They usually mark the Front Right and Left speaker as Speaker A just for this application. They will be the channels that would have a full range signal output so that is where you would connect the SSVC4. If you are still unsure, let me know the make and model of the Receiver. You may have a second zone output setting which may connect to the channels 6 and 7 (if you have a 7.1 AV Receiver) which is another place you may be able to connect to the SSVC4. TL

June 4, 2012
I am considering a sound system with 3 separate pairs of outdoor speakers around my pool. I am also looking at a dual coil sub-woofer for the pool area. Wouls the SSVC-4 Speaker Selector be a good choice for me? Can I use one of the "zones" to control the volume of my sub-woofer?
1 Answer
Hi John: if your subwoofer is passive with a built in crossover you will have no problem running the subwoofer from anyone of the four zones (powered by the same source as your three pairs). Even if you were to run a separate subwoofer amplifier you could connect it to the SSVC4 as Source B with your receiver/amplifier connected to Source A. So, yes this Speaker Selector will work for you. Another choice is use our DSM4 speaker selector with Dual Source as well but no internal Volume Controls. You could connect a dedicated outdoor volume controls in line for each of the three pair of outdoor speakers plus another Volume Control for the Subwoofer. These would be similar to the Impedance matching Volume Controls found in the SSVC4. You would set the impedance matching setting to 4x. You would run 16/4 or 14/4 from Receiver to Speaker Selector the out to each Volume Control then two conductor from the Volume Control to each speaker. I give you the alternative since we are back ordered on the SSVC4 until July. The Outdoor Volume Controls are OVC300 (white or Grey housing). Our CL3 rated speaker wire is also rated for direct burial and comes in 16, 14 and 12 gauge versions both in 2 and 4 conductor. We also recommend our Aqua Blue terminating connectors rated for direct Burial as well (filled with Silicon). Good Luck TL

I'm looking at the specs at the SSVC4, does this come in a D-100 and D-300 series like the SSVC6? The specs on the SSVC4 states 180w max per channel. But it also states in description 300w. The SSVC6 D-100 and D-300 states 180w max and 360w max respectively. I would really like 360w per channel but only need 4 channels? Thanks in advance Smokey
1 Answer
Hi Smokey: 180 watts would be the RMS or nominal rating. 300 watts would be peak. The unit features (4) 100 watt per channel internal Impedance Matching volume controls. Are you planning on only using two zones or four channels or four zones and eight channels. It takes two channels (left and right +/-) for a stereo zone. I am assuming you are utilizing eight channels and need the four zones. I believe the SSVC4 should be able to handle your application. TL

Hi Greg: The SSVC4 is a passive device that is strickly Speaker Level input, two of them (A & B) switchable per zone. All four zones feature a dedicated Impedance Matching Volume Control per zone. Output is Speaker Level as well. So all connections are using Speaker Wire both from the Amplifier/Receiver and out to the speakers. I hope that helps... TL

How do you hook up the speaker cables to the back of the unit? The instructions describe plug-in connectors that you loosen via two screws on either side of the connectors. There are no screws; it appears the only way to connect is working at the back of the unit. The website and instructions talk about easy to connect with plug in connectors. I looked at a picture on the back of the Niles speaker selector, and it indeed does have a screw on each side of the connectors. Any help/suggestions? Eric
1 Answer
Both the one Input and two Output connector located on the back panel are removable. The Input connector has 8 inputs to cover both A and B source, Right (-/+) and Left (-/+). There are two output connectors featuring 8 connections as well. Zone 1 - 2 and Zone 3 - 4 both with Right (-/+) and Left (-/+). They conveniently unplug from the unit so you have more leverage to screw or un-screw the individual set screw for each bare wire conductor input. TL/MA

Great Product
We had previously used a Radio Shack speaker selector system. The SSVC4 is a much better choice as it allows us to adjust volume levels independently for the outdoor speakers and indoor speakers in our clubhouse. Also appreciated the removable wire connection modules. This feature make it so much easier to do the original installation. The only negative feature our people have noticed is that it would be nice if there were numbers associated with the steps on the attenuation knobs, and pointers were in a visible color.

A must for multi-room speaker control. I noticed no discernible volume loss with all four channels running. I use it for small bookshelf and outdoor speakers that do not demand high wattage.

After returning a cheap ...
After returning a cheap plastic speaker switcher I bought from a well-known retail electronics store for $45, I decided to take a chance on a brand designed by a company that specializes in outdoor audio where speaker selectors are essential. My research paid off and I couldn't be happier. The build quality is very high, with an all metal chassis, solid volume controls that convey quality, and separate push button on/off switches for each speaker pair. It is the width of most DVD players and receivers, so it looks great in a rack. It is heavy enough so it doesn't slide back when you push the buttons. You can also run two receivers into the unit, and separately control whether each pair is driven by receiver A or receiver B. The back speaker connectors are in three strips that plug in and out for ease of installation, especially in a rack. You can run the wires to the front of the rack, install the wires, and then reach around the unit and plug them in. The only possible drawback is if you have huge speaker cable, as I doubt 12 or larger will work. This unit is designed for an 8 ohm receiver output and 8 ohm speakers, unlike cheaper units that will drop the impedence to 4 ohms which will not drive many speakers. You can spend twice as much on one of those high end audio brands, or spend less and get a lot more features. A great deal for the money.

This speaker selector ...
This speaker selector works good for the price. Other single source speaker selectors without volume control are much more than at OSD. I originally purchased this selector to power 3 seperate pairs of 6-1/2", 4-ohm, Alpine, marine speakers with an older Kenwood home theater receiver. Unfortunately, many "lower-end" receivers aren't capable of adequately powering several pairs of speakers like this and it kept cutting out. I decided to purchase the M15 amplifier from OSD to power my speakers and I just use the old receiver as a tuner and for all of my inputs. Now I am very happy with the sound and I have plenty of power to spare. I will come to OSD first for all of my electronics purchases. Very high quality at reasonable prices. Thanks!
