    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.

    Mark • 12/17/2019, 2:17:43 PM house was pre-wired with 6 zones, one pair of speakers per zone. There are OSD VCs and speaker selector. The receiver was a Sherwood Rx4109. The system as setup caused the Sherwood to become inoperable. Tried a Pioneer receiver. Same result. Put in a Dayton Audio 12-channel amp, with 40 watts per channel. The system sound has static and the warning lights on the front of the Dayton amp flash from blue to red, to blue, to red (blue being the normal operation indicator) within minutes of powering the system on. I think the speakers are OSD, but they're in the ceiling and I have not pulled them yet. The VCs have SVC-70 SHH-009 printed on the circuit board, so I assume that's the model. Any suggestion to get this whole house system functioning optimally (one zone does feature speakers mounted outside on the deck).

    Hi Mark, You can't run a system like that with a receiver. You'll need a high-current amplifier. Check out our AMP300.

    I purchased a Dayton Audio MA1240a amp which is comparable to OSD's MX1260 12 Channel Amp x 60W, so the question remains: "Why is this not working properly?" I do not know who wired the house system, but if they wired it in parallel, could this be cause of my problem? Thanks for responding! Mark

    I would say that the speaker selector you have doesn't have protection built in or it's not enabled. The selector should be able to limit the load on the receiver, Also your OSD VCs may not be impedance matching. This could also cause an issue.
    roger smith • 12/17/2019, 2:17:43 PM I am going to have my left and right speaker in two adjacent rooms that are separated by a door. Can I use one volume control for each speaker? Basically it would be a volume control for the left speaker and a volume control for the right.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Roger, That would create a 16 ohm load back to your amp/receiver, which most receivers aren't built to handle but if it could, then that should be fine. Understand that you would be separating stereo though.
    Walter • 12/17/2019, 2:17:43 PM I have two sets of 4 ohm speakers on our boat running from a Kenwood KDC-416S receiver.. I want to be able to control the volume for each set of speakers. What do you recommend? Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Walter, I'd go with the OVC300 to be safe.
