OSD SVC 100In Wall 100W Knob Volume Control, Speaker Impedance Matching (White, Black, Brown) Decora Style
OSD Audio's SVC100 is an impedance-matching volume control that lets you adjust the volume of a pair of speakers independently of other speakers within a whole house audio system. Ideal for areas such dining or conference rooms where you may want softer volumes or for saunas or garages where you may want higher volumes, the SVC100 maintains the full hi-fi audio frequency response with no low frequency roll-off. Equipped with the same features of volume controls that cost twice as much, the SVC100 is rated at 100 Watts peak and includes adjustable jumpers to add up to eight pairs of 8-ohm speakers simultaneously. The impedance-matching feature helps stabilize the ohm load going back to the amp or receiver to avoid overheating and damaging expensive equipment. A complete volume control kit that fits into a standard single-gang box, the SVC100 also includes the junction box, screws and assorted color trim plates (white, ivory and almond) so you can choose the color that best matches the room. This versatile whole house volume control is compatible with almost any dedicated audio zone or whole house system, and the 12-step rotary knob adjusts the volume from inaudible to loud and everything in between.
Features:
- Decora style impedance-matching volume control for whole house audio systems and dedicated audio zones
- Rated at 100 Watts per channel with minimal bass roll-off
- Impedance-matching feature stabilizes the ohm load so parallel connections of multiple volume controls can be installed without damaging the amplifier
- Front-mounted adjustable jumpers allow easy adjustment when multiple pairs of speakers are connected to a single receiver or amplifier
- Accepts up to 14-gauge wiring and fits in a standard gang box with a depth of 2.9'Includes junction box and screws as well as white, ivory and almond trim plates to match any room d'cor
- Precision electronics provide low distortion and a ruler flat frequency response
- 12-step linear rotary-style knob for a wide range of listening volumes
- Installs easily and works with almost any audio system
What Is Impedance Protection?
Speakers are specified by impedance, which is a measurement of resistance to alternating current, and a common value for speakers is 8 ohms. When you're connecting multiple speakers to a receiver or amplifier, you need to stay above the amp's minimum load requirements because going below the impedance rating can overheat or even damage expensive equipment. The SVC100 allows you to match the impedance with the number of speakers being controlled with the capabilities of your amp. A basic multi-room system will typically have an amplifier/receiver, a speaker selector, four to eight pairs of speakers, and volume controls. Impedance-matching volume controls feature three settings depending on how many speakers you are connecting. For one to two pairs of 8-ohm speakers, the setting is 1/2x; for three or four pairs of 8 ohm speakers, the setting is 4X. Keep in mind that volume controls do not add gain (volume) to your speakers but simply attenuate the volume up or down. During setup, you'll set the source volume to its optimum level, then the volume control turns the sound down to inaudible levels.

I am installing a pair of speakers in the kitchen and a pair of speakers in the patio and plan for each to be on their own zone from a separate 4 zone amp. My question is can I install both volume controls side-by-side in a 2-gang box without any issues? I just don't know if they generate any type of radio wave or something that might cause a problem like a hum or something if two volume controls are placed close together.

Hi Stephen,
That shouldn't cause any issues as long as there aren't any other electrical components next to them.

I have a boat 4 channel radio receiver and 2 pairs of speakers, one pair is 4 ohm and one pair 8ohm. I was trying to figure out if I need 2 volume controlers so I could turn the 4 ohm down and 8 ohm up for playing both pairs at the same time. Or is there a better way ? the 4 ohms volume is much higher then the 8 ohm.
Thanks

Hi Steve,
I wanted to check with you about what AMP you will be using and what speakers you have?

I connected 2 Yama ha outside speakers to my receiver and they work fine...however..I couldn't lower the volume outside without lowering the volume inside. So..I purchased the volume control and it does nothing...The input and output are correct...what do I need to do?

Hi John,
Email our return department to do some troubleshooting and get an RMA for repair/replacement. Thanks.

Want to attach 3 pairs of model AP450 or AP490 speakers to my older JVC RX662V. This receiver has an output of 110 watts per channel into 8 ohms.
This receiver has 2 buttons for 2 sets of speakers. These new speakers would alone be on this second circuit.
My GUESS is the amp can handle it since the surround sound side is driving 6 speakers with ease. Since I want volume control, is the impedance-matching control the way to go?
However, Viewing the on-line Owners Manual, I don't have a clue as how it should be wired.
THANKS!

Hi Ed,
It's actually unlikely that the receiver can handle more than a pair of speakers per zone. If you have only the one extra zone available, running more than a single pair of 8ohm speakers could fry your receiver or damage the speakers. The surround sound side is different because each speaker has its own output, whereas the second zone only has outputs for two speakers. In our opinion, you should run an external amp to power these outdoor speakers safely. You can run something like our AMP200 or the SW-RX5502. Let us know if that helps. Thanks!
