    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.

    Pat Wright • 12/17/2019, 2:17:43 PM I am having trouble with Bose 151 speakers. When I hook them up two of four speakers work. On the first receiver I thought one side of the receiver was bad. It appeared the left side was gone. I then hooked up a different receiver and had the same problem. I was told I need a impedance matching volume control. Will this correct the problem?

    Hi Matt, Keep in mind that the speakers you have are 4 ohm so you'll need to check if the receiver you are using is stable at 4 ohms. Also, how are you wiring the speakers? You wouldn't want to daisy chain them; instead, do home runs for each speaker (connecting to its own dedicated channel). If that doesn't help, try swapping the speakers on different channels to rule out that the speakers are not defective. CL/MA
    Jeff Sweater • 12/17/2019, 2:17:43 PM I'm going to run three zones of speakers in the house that I'm building for the kitchen, dining room, and outdoor patio speakers with my B speaker output (an 8 ohm, 90 W amplified signal) from my Onkyo 607 receiver (these Ill use the A speaker outputs on my receiver to power ODS ICE660 speakers in my living room for surround sound). I'm trying to do it on the cheap for now and will purchase an amplifier to power these three zones if I find my receiver is not powering these speakers as well as I'd like. I'm going to run the amplified signal from my receiver to a 4 zone OSD speaker selector switch, and then run in-wall speaker wire to a SVC100 OSD volume controller within each room/zone. With that said I have the following questions: 1. Can I run a 2 conductor wire from the speaker selector to the volume controller, and then run two conductor speaker wire to each 8 ohm speaker so they are in parallel? Or does that not provide me any advantage and I should just daisy channel these speakers in series and save the wire? I know I can get 4 conductor speaker wire and run it to the volume controllers, but Im not sure what that really gains me? 2. Is there is anything Im missing within the layout I discussed above, or are there any other things I should consider? Thanks! Jeff

    Hi Jeff, How many speakers are you running in each room? If you only have a location for a single speaker, then you should consider our Dual Voice Coil Stereo speakers: In-Ceiling (ICE640TT), Patio (AP550TT) or Rocks (RS850TT). You should be using four conductor 16 gauge wire from the Onkyo (2nd zone speaker level output) to the Speaker Selector (recommend DSM4). Then run four conductor 16 Gauge (single cable with four internal conductors) to each Volume Control (Left, Right, +/-). Next, connect either 2 conductor if you are connecting a stereo pair in the zone or run four conductor to the Dual Voice Coil speaker. Youll want to run your system in stereo since that is the output from your Onkyo. Then make sure to set the Impedance setting on the Volume Controls to 4X. Make sure to turn the protection switch on the DSSM4 to the Off position (disable) since the Volume Controls are handling the protection. If you are not happy with the output, then you can look to add an external amplifier that can connect to the ONKYO 607 Pre-Amp Outputs for Zone 2. You would then connect the external amplifier to the Speaker Selector (either our AMP150 or AMP200) and drive the Volume controls and Speakers in the same setup. Adding with no subtraction. We stock both the 16/2 and 16/4 CL3 speaker cable in 50, 100 and 500 feet. TL
    Jeff Sweater • 12/17/2019, 2:17:43 PM Thank you for your responses. I'm going to run 2 speakers from volume controller in the Dining Room, and two from volume control out to the Patio. I want to install 3 speakers in our Kitchen/Breakfast Area, but if that is more painful or expensive than it is worth, then only installing 2 speakers in the Kitchen would suffice. Jeff

    Hi Jeff, There is a simple solution. Run three each of our ICE640TT in the kitchen. Connect them together after the volume control. On two of the speakers you will connect only one of the voice coils (there is a16/8 ohm switch on the back of the speaker, set it to 8 ohm). On the third speaker, use a four-conductor cable making sure to connect both voice coils and setting the switch on the back to 16 ohm. Take a short length of four-conductor cable from the volume control then bundle the positives for left and right and the negatives for left and right so they are connected in parallel. You should not have a problem since the volume controls are set to 4X, which is how many pairs you have for the total system. If you were to add another pair to the fourth zone of your speaker selector, you would have to change all your settings to the 8X. The beauty of the DVCs is they also feature Dual Tweeters, which increases your coverage directly underneath the speaker. We have these available in both 8" and 6.5" TL
    Jeff Sweater • 12/17/2019, 2:17:43 PM Hi TL, One last question on this 3 speaker layout to make sure I have thoroughly beat this horse to death. Attached is a wiring schematic is created as reference to make sure we are on the same page. You said I should buy 3 of the dual voice coil speakers (ICE640TT) and I should run 4 conductor wire to one speaker (lets say speaker S2) and then only 2 conductor wire to the other two speakers (speakers S1 & S3). I was wondering what the reason was for having speakers S1 & S3 as dual voice coils when you are recommending I only power one voice coil on each of these speakers? Couldn't I just use two single, 8 ohm voice coil speakers and one dual voice coil set to 16 ohms instead?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jeff: The advantage of theses Dual Voice Coil, Dual Tweeter speakers is when you connect only a single voice coil both tweeters are still playing giving a broader dispersion pattern beneath the Speaker itself. This would be considered an upgrade over a standard stereo pair featuring just a single tweeter. You can certainly use a combination of a pair of ICE640s and a single ICE640TT as you suggested. This would also be a little more affordable. You would not be wrong going either way. TL
    Brett • 12/17/2019, 2:17:43 PM I want to power two pairs of 8 ohm speakers, one outdoors and one indoors using zone 2 of my receiver which can handle 6-16 ohms. Can I use two of these and set one of them, for the outside, to 1x and the other for the inside to 4x so that the offered load to the receiver is 6.4 ohms? The reason for doing this I thought was to give more power to the outside speakers. I got 6.4 = 1/(1/(8x1) + 1/(8x4)) = 1 / (1/8 + 1/32) = 1 / (0.15625) = 6.4. Or is best just to set each to 2x? Thanks

    Hi Brett: I would purchase an OVC100 for outside and an SVC100 for inside. I am not sure if the settings you are proposing will have the desired effect on the output of the two speakers, it is an interesting theory. Typically you set the impedance settings based upon total number of 8 ohm speaker (in the case of 4 ohm speakers they count as (2) 8 ohm speakers) you will be connecting in parallel. I am thinking you set both to 2x and see what you think. Setting the inside pair to 4x would not cause any damage so it might worth the try. TL
