Features and Specifications: The OSD Audio SVC100 Knob-style Volume Control is one of our most popular models. Rated at 100 Watts peak, this unit shares the same capabilities as the slider version and is built with close attention to performance, reliability and durability. Some folks prefer the knob control over the slider type which is why we offer both. As you can see by the many reviews, the result is a blend of transparency and functionality, with low distortion and ruler flat frequency response. The unit comes with White, Ivory or Almond faceplates and whether you go with knob control or soft-touch sliders, OSD Audio offers convenience and style with colors to match any decor.
Features
• Control volume from any room
• Wall-mounted volume controller works with any audio/video system
• Low distortion and ruler flat frequency response
• All installation materials included
What Is Impedance Matching?
Volume controls do not add gain (volume) to your system but attenuate the volume up or down. The sound source is turned up to optimum levels and the volume control reduces the sound to almost inaudible levels. There are two types of volume controllers: Impedance matching and Non-impedance matching. A basic multi-room system will typically have an amplifier/receiver, a speaker selector, 4 to 8 pairs of speakers, and volume controls. To protect the amp, the speaker selector has impedance matching that you can turn on or off (manually) depending whether you have impedance matching volume controls. More complex multi-room systems often have a volume control for each pair of speakers that is attached to the speaker selector. Impedance-matching VCs offers more precise protection for the amplifier/receiver versus the protection built into the speaker selector. Remember, when adding impedance matching, you must turn off (disable) the protection in the speaker selector. Most impedance-matching volume controls feature three standard settings: 1/2x, 4x and 8x, while some add a 16-ohm setting like our VMS series. These settings correspond to a chart in the owner’s manual based upon the type of amplifier (4 or 8 ohm) and the number of 4 or 8 ohm speakers that you will be using in the multi-zone/room/speaker system. Click on the Product Information icon below. The Q&A section also has good stuff about VCs.

Questions and Answers:  By Philip from Ohio on January 6, 2012 Does this control turn the speakers off the the volume is all the way down? By Customer Service - Q&A on January 6, 2012Answer: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.
CLBy George Balli from Ajax,ON.Canada on November 11, 2012 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? By Customer Service - Q&A on November 12, 2012Answer: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 won’t 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 1371By Customer Service - Q&A on November 12, 2012Answer: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 By morgan meeks from Buford, Georgia on November 16, 2012 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 By Customer Service - Q&A on November 19, 2012Answer: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)
CL1382By Ken from CO. on February 4, 2012 Can I put 2 pair of speakers on 1 svc100? By Customer Service - Q&A on February 6, 2012Answer: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. By Rick from Indianapois, in on December 9, 2012 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. By Customer Service - Q&A on December 11, 2012Answer:Hi Rick,
Can you supply us with more information? We’ll 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 - 1457By Customer Service - Q&A on December 11, 2012Answer: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 - 1457By scott shane from waukesha on February 13, 2012 Our church wants to put a speacker with a volume controller switch in our nursery can you hook this up to a sound board?? By Customer Service - Q&A on February 14, 2012Answer: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.

By Simon from quebec, quebec on December 12, 2012 Is there a mute mode on these? Is it possible to turn the volume to 0? Thanks By Customer Service - Q&A on December 13, 2012Answer:Hi Simon,
The SVC100, SVC300, OVC100 and OVC300 models do not turn off when you rotate the knob counterclockwise. They will turn the sound down so you no longer hear the music but the current is being diverted to the transformers. That is why we recommend if you are using a speaker selector, you should use the on/off switch to turn off the zone when you're not going to listen for extended periods. We do have SVC205 impedance-matching volume control featuring an actual on/off switch on the front of the panel. These cut the signal completely. Our resistor-based series, including the VKR120K and OVC305R, do turn off when rotating the knob all the way counterclockwise until it stops. These are considered our best sounding volume controls but do not have impedance-matching capability.
TL/MA- 1460By Jeff Sweater from Lititz, PA on April 12, 2012 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 I’ll 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 I’m not sure what that really gains me?
2. Is there is anything I’m missing within the layout I discussed above, or are there any other things I should consider?
Thanks!
Jeff
By Customer Service - Q&A on April 12, 2012Answer: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. You’ll 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.
TLBy Jeff Sweater from Lititz, PA on April 12, 2012 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 By Customer Service - Q&A on April 12, 2012Answer: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"

By Brett from Phoenix, AZ on August 7, 2012 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 By Customer Service - Q&A on August 8, 2012Answer: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.

Very Clean, Very Functional
August 27, 2012
This control is great. Always be prepared with the proper
sized tools such as a very small screwdriver for work with these
types of controls. Also always use the proper gauge of wire - too
big is too big! The depth of the control can be a little
challenging depending upon your application. I installed one of the
volume controls in my gazebo next to a hot tub thus needed a
weatherproof enclosure. The depth of the control prohibited use of
an off-the-shelf solution. I instead used two waterproof enclosures
bolted together to provide sufficient depth to accommodate the
control. Looks great and works great.
Pros:Easy To Set Up, Easy To Use
Cons:Depth can be an issue
