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 have a 4 ohm amp driving two 3 ohm speakers. I want to install a volume control to control each speaker volume independent of the other. Or I would like to control one speaker and use the standard volume output on the other speaker.
Any idea what I need to do to control the speaker volumes independently?

Hi Jerry:
Could you please clarify a few things?
1) What four channel power amplifier do you have (Brand and Model)
2) What 3-ohm speaker are you referring to (again, Brand and Model)?
3) Are you saying you have two pairs of speakers or two speakers each?
4) The SVC100 is a stereo Volume Control.
Please let me know, thanks in advance.

I have four zones that will be powered by an AMP200 or AMP300 and switched by a selector with impedance protection switched off. All speakers will be 8ohm, and all will be controlled by SVC100 controllers. One zone will terminate to an A/B, A&B switch, then run into two volume controllers. I will sometimes switch to both A and B powered at the same time. Having this one zone wired with four speakers in parallel, what should I set my volume controllers to? Should the two-volume controller's zone be set differently than the other three? Will this cause this zone to have a lower volume since its now a 4ohm load? Thank you.

I have an onkyo TX nr676. For main room I have four Polk audio rc 80i speakers and a center speaker all rated at 100w. For outdoor, I am getting a pair of Polk audio 200 patio speakers. Amp and speakers all at 100 watts per. I want to put volume control on outside pair for zone 2. I have the svc 100 for the pair. Is that the right control? What should switch be set at?

Hi Jim:It sounds like you are planning to connect your pair of Polk outdoor speakers to the Zone 2 output of your ONKYO TX-NR676. If that is all you are planning for your system with no intention of expanding in the future, then we would recommend the VKR120 for indoor mounting or the OVC305R Resister based outdoor weatherproof version would work the best. If you are planning on expanding in the future, then your two choices would be between either the SVC300 (indoor) or OVC300. The SVC100 rated at 50 watts RMS continuous with a peak of 100 Watts. The SVC300 and OVC300 feature Impedance Matching and for your application (one pair of 8-ohm speakers) your impedance matching setting would be 1/2X. You may find that a couple of speakers is not enough coverage for your outdoors application. Good luckTL/5579
