    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.

    George Balli • 12/17/2019, 2:17:43 PM I want to install 2 speakers in my kitchen, 2 in the living room and 2 outside on the patio. If i have a receiver from my home theater system, do I still need another one or an amplifier? How should I wire them?Which control system would you recommend and which volume control?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi George, If you are using your existing receiver for your home theater surround sound system, you'll need to add an amplifier for your whole house speakers. You could add another receiver but for whole house audio, you wont need features such as surround sound processing, which is more applicable to home theaters. Our AMP200 2-channel amplifier would do the trick. The DSM4 speaker selector lets you add up to 4 pairs. You would wire each speaker with a direct line (home run) to the volume control and then to the speaker selectors. CL/MA 1371

    Hi George, If you are using that receiver for your surround sound, then it sounds like you need to add an amplifier for your whole house speakers. Our AMP200 would do the trick, with our DSM4 speaker selector- giving you room for up to 4 pairs. You would wire each speaker with a direct line (home run) to the volume control and then to the speaker selectors. CL 1371
    morgan meeks • 12/17/2019, 2:17:43 PM I was wondering if these svc100 volume controllers have transformers on the back of them do the speakers that I hook them to have to have a 70v transformer as well and these will work with 70v systems right? Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Morgan, The SVC100 are Stereo 8 ohm Volume Controls. For 70 V systems use our model number OSD-MONO70-VC (now back in stock as of today) CL1382
    Rick • 12/17/2019, 2:17:43 PM I have run my home on the following for about 6 years until my tuner fuses burned out. I never Could run the volume too high or the Protect warning on my amp would shut it down. So I never ran The tuner more than 50 % volume. Heck, it would affect my fluorescent light in the room it was in. I have 5 rooms, each with the transformer type volume controls. A separate run from the selector box to each volume control then out from each volume control to 2 speakers (left & right). I had set the volume controls to x8. However, after my amp failed, it's fried, I tested the ohms on the system. I checked the output from the selector to the tuner ( tuner removed) and I was getting a reading of about 2.9 to 3 ohms. According to the chart, I should be getting around 7.5 ohms. So I set them all to 16x then read them again to get about 1.9 ohms. I don't get it, my tuner Is rated for 8-16 ohms. That's way to low. At 16x if I read one set alone I get about 15.5 to 16 ohms. Turn on two sets I get around 8.9 ohms, the third set halves it again and so on. My point is, any more than 2 rooms ( 2 pairs of speakers) those volume controls are not raising the impedance like they should. Am I not seeing something here. I really think the tuner was overloaded for a long time and it just gave up. I want to be sure I have these wired correctly before plugging in another tuner. One note, when set to 8x, If I switched the selector protection on, I would get about 8 ohms.

    Hi Rick, Can you supply us with more information? Well need to know the model receiver, speakers, and volume control and speaker selector before we can tackle the issue. Are you enabling the protection switch? Let us know so we can give you an accurate answer. TL/MA - 1457

    HI Rick: Can you supply us with more information, What Receiver are you using. Whose Volume Controls (are we to assume they are SVC100's) are you using? What Speaker Selector and are you enabling the protection switch. What speakers are you using. I want our acoustic engineer to chime in on this one but need the additional information before attempting to tackle the issue. TL - 1457
