Impedance-Matching Protection Safeguards Amplifiers
To help protect expensive audio equipment, this 4-zone high-power speaker selector includes impedance-matching frequency protection circuitry that reduces subsonic signals so you can safely drive multiple pairs of speakers without going below the amp's impedance ratings which can cause it to overheat or shut down.

Something that is regular priced of $300 that’s now $88 causes me to question -why such a big discount? Is there a newer model that replaced it or something?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Rick:
Yes, $300 may be a fabricated MSRP (manufacturers suggested retail price). We had been selling this model at a MAP price of $129.00 MAP (Minimum Advertised Pricing) for more than ten years. Recently a couple of our competitors copied our design and had forced us to lower our price to meet competition. This design has not changed in the ten years we have been selling it online. It was a good value at $129.00, now a great value/performance deal at its current price.

Hi, doing some research on the ssvc4 and an amp for whole home audio. I have 4 separate rooms, each with 1 speaker that I would like to run mono. I do not have an amp/receiver yet as this is my biggest concern, how do I get mono to 4 separate speakers in zones with centrally controlled volume.
Here are the specs on my speakers:
Audio Specifications
Sensitivity(2.83V@1m) 89dB
Frequency Response(-10dB) 32Hz – 20kHz
Nominal Impedance8 ohms
Crossover Frequencies2.4kHz
Recommended Maximum Amplifier Power100 watts
Any recommendations would be appreciated!
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jerome:
I am assuming that you have already installed your speakers and have a two conductor wire (+/-) running from each speaker back to a central location. It would have been easier if you had run single four-conductor speaker wire (Right: +/- and Left: +/-) to each Zone and had picked out a DVC speaker with both Dual Voice Coils and Dual Inputs. The DVC speaker typically features two Tweeters as well. It takes a stereo signal then sums both channels into a Full range mono signal. Again, assuming you have speakers in place and two conductor speaker wire to each speaker you could use the SSVC4. But to pull this off, I would suggest using our AMP200 along with our Pre-1 Preamplifier and connecting your source to the Preamplifier. Check out the Pre-1 on our website. First, the Pre-1 features a 1.5V output gain for whatever source you connect to the selectable inputs (three plus a Phono input). The second key feature is the Mono stereo switch which combines the stereo input of whatever sources you select. So even though you will connect the Pre-1 to the AMP200 (Right and Left channel) and then the Right and Left input of the SSVC4 Source A. Then connections on the SSVC4 would be as follows; Zone 1: Left +/-, Zone 2: Left +/-, Zone 3: Right +/-, and Zone 4: Right +/-. You will have the ability to control the volume for each zone and also be able to turn the zone on/off as well. So if you need further clarification, please contact me at tim@osdaudio.com. Also, check out our ACE850 as an example of an 8" Dual Voice Coil speaker. Note: There are many source options to choose from including Turntable, CD/DVD player, SONOS Connect, AMAZON Dot, Chromcast Audio, iPod, Bluetooth Receiver, Lap Top, TV among others.
Good Luck

Hello,
Im currently doing a sound system install at a local restaurant and Im wondering if the attached photo of my planned setup will work. Ive been reading through the customer questions here and other sites and they have mentioned about using a amp/mixer so it will give audio sources the extra volume it needs rather than just plugging the audio sources straight into the SSVC4 Just wondering if the Mackie mixing board in the photo will work as to what im doing. Kind of curious as ive never used a zone/speaker selector like this before. Thanks!

Hi Jeremy:
I am familiar with the Syracuse area, having married a girl from Onondaga Hill. Both my parents and In-Laws lived in Skaneateles for many years. Where is the restaurant located?
Regarding your system; Both the Mackie Mixer and the DENO Pro Tuner/Internet Radio with Bluetooth are Pre am only. They need to connect to an amplifier like the AMP300 or XMP300 before connecting to the SSVC4. Plus your drawing shows only four each of the Yamaha speakers (should that be four pairs where the SSVC would work). The Touch Tunes System looks like a streaming Jukebox for bars and clubs (app driven). But would like to know what hardware you use for of the Touch Tunes System (That may be powered based upon 7your drawing with the direct connection to the SSVC4). So please let me know how many total speakers you are looking for your setup. And what are you using to play your Touch Tunes System? Do you have a Blueprint or layout of the project? tim@osdaudio.com
I will send you a diagram and send to your email.

Does this mean the sound is mono and not stereo? And what if you have surround set up in one room ? This amp has a & b speaker switch’s but both can’t be played at the same time. I have another set of speakers in another room that I would like to have hooked up.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Carl:
The SSVC4 is a four zone speaker selector with internal Impedance Matching Volume Controls and Dual Source switchable per zone. It is a passive device with no power supply. You need a powered source for both A and B source input to utilize the dual source capability. You can use it with an Audio Video Receiver as long as you utilize an external amplifier connected to your Zone 2 Preamp output. No Audio Video Manufacture recommends connecting more than a single pair of speakers to a Zone 2 speaker level output. The SSVC4 is a stereo speaker selector with four stereo zones (Right and Left). The alternative is to go with a passive speaker selector utilizing impedance matching volume controls (one IMVC for each zone) connected to an external amplifier from the Zone 2 Preamp output. The point is we have solutions for almost any application.

Mike • 12/17/2019, 2:17:43 PM
This is what I have:
Living Room:
- 4 built in speakers (2 front and 2 rear)
- interior speaker wiring for all 4 speakers with speaker jacks on the wall where the tv resides
--- also want to add a subwoofer for home theatre
Outside:
- 2 built in speakers
- wired to living room with speaker jacks on the wall where the tv resides
I do not have a receiver, and am trying to determine what to get. I'm now thinking that since I'll want the 5 indoor speakers OR the 2 outdoor speakers to be playing, this SSVC speaker selector would not work. What would the receiver requirements be?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Mike:
You need to look for a 7.2 Audio/Video Receiver with Zone 2 output. Something like the ONKYO TX-RZ620 or DENON AVR-X2400 H. Both these Receivers feature 7 channels, 5 of which will run your home theater (inside your living room) including 1 to 2 subwoofer outputs plus you have 2 channels (channels 6 and 7) which can be connected to your two outdoor speakers (I am assuming two speakers, one stereo pair). You can control your Receiver with a dedicated app and play the Home Theater while controlling your Zone 2 independently. Or you can switch your Home Theater to stereo mode and listen to the same source for both inside and outside. That would be all you need to control your existing system. You can expand your Home Theater by using channels 6 and 7 for DOLBY ATMOS/DTS:X. You would need to add two more speakers to your living room setup (in-ceiling would be an option depending on accessibility). Then you would need to add an external amplifier for your outdoor speakers. Then if you wanted to expand your whole house system, you would look to add a speaker selector like the SSVC4 with Built-in Impedance Matching Volume Controls. It depends on if you want to take advantage of all the features available to you.
Good luck
