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 would like to know if this volume control will work on my two speakers I have on my patio/deck. The speakers are connected to the main amplifier in my living room...the speakers are weather proof..we have sound, but I have turn the stero up in the house real Loud to here the speakers outside. Will this volume control work ok with my setup??right now the patio speakers are on an on/off switch..thanks for your reply

As long as the speakers are 8 or 4 ohms & each wired individually, this volume control should work just fine. It is not an outdoor volume control, so it will have to be placed indoors or somewhere where it is protected from the elements.

How deep is this item. I'm afraid the electrical box I installed may not be deep enough. What are all the dimensions?
Customer Service • 12/17/2019, 2:17:43 PM
The depth on this volume control is just shy of 3".
Philip • 12/17/2019, 2:17:43 PM
Does this control turn the speakers off the the volume is all the way down?
Customer Service • 12/17/2019, 2:17:43 PM
Philip,
This volume control would regulate the electrical current your speaker is receiving, If the volume on your amp / receiver is up and the control is all the way down, there could be a very minimal amount of volume still noticable (less than 10%) Although we do have a volume control with an On/ Off feature.Take a look at the SVC205.

Can I put 2 pair of speakers on 1 svc100?
Customer Service • 12/17/2019, 2:17:43 PM
HI Ken:
Yes you connect two 8 ohm speakers with this volume control. The power rating (100 watts) pertains to the amplifier or receiver that you are using. If you were running a 150 watts plus you would want to step up the SVC300. Note, If these are the only speakers you are connecting to the system then set the impedance matching to 1/2X. The speakers should be run in parallel (connecting the positives together and the negatives together seperately) The amplifier should still see an 8ohm load.

Our church wants to put a speacker with a volume controller switch in our nursery can you hook this up to a sound board??
Customer Service • 12/17/2019, 2:17:43 PM
Hi Scott,
First, you need to determine if this is a 70V system or 8 Ohm. 1) If it's a 70V system, you'll need a mono volume control such as our OSD MO70V. Make sure the speaker has a 70V tap (check out our 70V speakers) and then connect the volume control in the nursery before connecting to the speaker. Note: if this is a two-conductor connection (+/-), then it is most likely 70V. 2) If this is a four-conductor connection (+/-, R & L), then the SVC100 should work (8 ohm system). Make sure to set the impedance matching switch to 1/2X.
