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 SCV100 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.

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.

More about Impedance Matching

All speakers have an impedance rating, typically 8 ohm for a pair of home speakers. To operate in the safest mode, most standard amplifiers and basic two-channel receivers are rated for an 8-ohm incoming load. To operate safely and consistently, the amp needs to see an 8 ohm load, and that’s where speaker selectors and impedance-matching volume controls come into play. In a basic multi room system, only a Speaker Selector is used to connect the speakers to the amplifier/receiver. Not only does the Speaker Selector allow you to connect multiple speakers to the amplifier but also adds internal Impedance Protection which is enabled by a manual protection switch. Both our ISS and DSM series Speaker Selectors feature internal Resistors that protect the amplifier. The down side is that the power rating normally 140 watts is cut in half when the protection switch is enabled so rated at 70 watts with protection. In a standard multi-room system (using Impedance Matching VC) you will typically have an amplifier/receiver, a speaker selector with 4 to 8 zones, and volume controls connected to all the speakers. Impedance-matching volume controls provide more precise protection for the amplifier/receiver versus the protection built into the standard speaker selector. Plus with the protection switch in the off position you will have the maximum power handling capability of the respective speaker selector. It is important that the protection switch is turned off when using the Impedance matching Volume Controls. 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. You can use both 4 and 8 ohm speakers when setting up your system. But you need to count a 4 ohm speaker as two 8 ohm speakers when calculating your Impedance setting.

Can I add 2 pairs of speakers to 1 volume control?
1 Answers
Hi Ryan: Yes you can connect a second pair of speakers to this volume Control. I would first recommend stepping up to a SVC300. Then you need to look at what else you are planning to do. Is this only two pair speakers connected or is there more to the story. We do not recommend connecting more than two pair of speakers to a volume control. There are other factors, what is the impedance of the pairs, are they the same? What are you connecting it to, Zone 2 of a A/V Receiver or to a 2 channel power amplifier like our High Current AMP200. Is there a speaker selector involved as well? Let me know if here is more to your system, tim@osdaudio.com TL/4470

I ordered this SVC100 Volume Control to replace a NXG NX-V70 Volume control that was not working (one of the two speakers connected to this NXG VC was silent). When I installed the SVC100 both speakers connected to it play but the volume control does not change the volume of the speakers at all. It's the same volume with the switch setting at each of the 3 switch settings 1/2x, 4x or 8x. This volume control runs back to a pyle speaker switch without volume control. There are 5 sets of speakers going through the speaker switch and the other 4 sets work fine with their NXG NX-V70 volume control. Unfortunately that volume control is no longer available. Why doesn't this SVC100 volume control work for me?

Hi Karen: It sounds like you have it hooked up backwards. Check to make sure the leads coming from the Speaker Selector is connected to the inputs of the SVC100 and the speakers are connected to the Output side. Please let us know if that helps. tim@osdaudio.com. TL/4608

I'm looking at adding something to my RV to control the different zones that it currently has. I find the speakers in the RV are to loud and the ones onutside are too quiet. It is the typical car stereo set up. 12Volt DC supply. Each speaker is controlled with its own feed. Each zone (3 in total) has two speakers each with its on feed (Left/Right). Would something like this work? Thanks.
1 Answers
Hi Tan: In order to answer your question, would nee additional info. First are we talking about three zones with two pairs each per zone? Did you wire the two pairs per zone in Parallel (Parallel doubles output, series cuts it in half). Will need to know which speakers you are using, Brand and model number (a 4 ohm speaker will play louder than a 8 ohm speaker).What we will be able to tell from the specs of the speaker is the sensitivity of the speaker. Typically sensitivity is measured in decibels usually between 86 and 92 dB. The higher the number (say 91 dB) the more efficient the speaker and will play louder than a speaker rated at 88dB (3dB is doubling your power) Lastly you need to understand the speakers in the RV are in an enclosed space and will play louder than the speaker outside since it is trying to fill a much larger area. The single volume control will not help you in this application... tim@osdaudio.com TL/4465

How do I test this
1 Answers
Hi Jim: You would have to connect speaker wire from the amplifier to the inputs on the SVC100 Volume Control then connect speaker wire from the SVC100 outputs to the inputs of the speakers you want to control the volume on. Make sure you turn the volume knob clockwise till it stops (fully open, actual volume from the amp). Turn your amp/receiver on and If music is playing it is connected correctly. Then start turning the knob counterclockwise slowly one click at a time. Each click should reduce the volume 3 to 6 db depending on the click until you hear no sound which depending on your volume levels on the amp may be one or two clicks before the knob stops. Now you have tested the Volume Control. Note these volume controls are antenuators, where they reduce the volume by diverting the signal into the transformers. There is no power to these volume controls they are passive devices. TL/3665

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.

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).

June 14, 2014
Want to attach 3 pairs of model AP450 or AP490 speakers to my older JVC RX662V. This receiver has an output of 110 watts per channel into 8 ohms. This receiver has 2 buttons for 2 sets of speakers. These new speakers would alone be on this second circuit. My GUESS is the amp can handle it since the surround sound side is driving 6 speakers with ease. Since I want volume control, is the impedance-matching control the way to go? However, Viewing the on-line Owners Manual, I don't have a clue as how it should be wired. THANKS!
1 Answers
Hi Ed, It's actually unlikely that the receiver can handle more than a pair of speakers per zone. If you have only the one extra zone available, running more than a single pair of 8ohm speakers could fry your receiver or damage the speakers. The surround sound side is different because each speaker has its own output, whereas the second zone only has outputs for two speakers. In our opinion, you should run an external amp to power these outdoor speakers safely. You can run something like our AMP200 or the SW-RX5502. Let us know if that helps. Thanks! BM 2750

I am totally confused about the impedance settings!! I have purchased 3 of these VC's and 3 dual voice coil ICE800TTWRS Stereo speakers. I will be running all 3 from my Zone 2 connections from a Yamaha RX-V673 amp. a) Can I just connect all 3 straight to my amp? b) What Impedance setting should my VC's be set on? The stereo speakers have an 8Ohm Impedance, but is that per coil or per speaker?? Thanks in advance for any help. I don't want to blow my amp up!!
1 Answers
Hi Graeme, Thanks for asking! First of all, I would advise against running all 3 of these speakers off the Zone 2 of your receiver, as that zone is probably only intended to run 1 pair of 8ohm speakers, which in your case would mean on dual tweeter speaker (contact Yamaha to confirm). What you need is an external amp that will be dedicated to these dual voice coil speakers. Check out the AMP200. As for the volume controls; you want to set each according to how many pairs or dvc speaker you are running. In your case each should be set at 4x, because you should round up. Let us know if this helps. If you have any further questions, please let us know. Thanks! -BM 2260

1 Answers
Hi Stephen, First, I would just like to mention that a lot of receivers aren't built to power multiple sets of speakers off the B zone. Typically they are intended to have a single pair of speakers running at 8ohms. Anything more can affect the receiver and or speakers over time. Many of these receivers will specifically warn against it in the owner's manual. They may mention speaker selectors too. That being said, you can run 4 speakers off a volume control (in parallel), but it would be best to run that with the SVC300, not the 100. Thanks. -BM 2205

Is there any problem with doing this, and what is the best way to wire this successfully? Thanks.
1 Answers
Hi Mark, Receivers have as many outputs as speakers they can drive. We would not recommend putting two volume controllers on one channel. Consider buying the AMP200 instead. Unlike your receiver, this high current amp can handle doubling up on one channel. With your current receiver, you can add this volume control to one pair per channel. CL/MA 1984

I have new construction and need two volume controls for the outdoor speakers, both are outside and in covered areas, would these be ok to use. They are not exposed to rain. The boxes are already flush mounted. I thought I read something about these not being able to turn volume up, only down..is that correct?
1 Answers
Hi Andy, The volume control is a passive devise. It does not add power; rather it attenuates what power it is given. Turn the volume all the way up on the control. From your amp, turn the volume to the maximum level you would ever want. Then at the volume control, turn it down to a comfortable level. This technique gives you room to go up and down in volume as you please. CL/MA 1960

I have patio speakers (8 ohm) and inside stereo speakers (4 ohm) connected to a speaker selector with impedance protection and my problem is the inside volume is much louder than outside. I am using a 5.1 surround sound receiver to drive them connected to the main left and right channels. Will this impedance matching volume control even out the mismatch volume. I intend to connect it only to the pair of speakers on the patio leaving the inside speakers unaffected so I don't have to remember to check the volume controller when using the surround sound for movies. Thanks, Loren
1 Answers
Hi Loren, The issue is that the 4-ohm speakers will play almost twice as loud as the 8-ohm speakers you have outside. The volume control is a passive device that does not add gain; therefore, whatever the volume you have playing through the system, you will only be allowed to turn the volume down, not up. You really need to use the volume control with the inside speakers so you can turn them down. I would recommend using our VKR120 resistor-based volume control while continuing to use the speaker selector with the protection enabled. This way, you can listen to the outdoor speakers as loud as you want and use the VKR120 to attenuate the inside speakers to an acceptable level. You can turn the VKR120 to full off (all the way counter clockwise until it stops) as well. In theory, it also sounds better than the transformer impedance- matching volume controls. TL/MA - 1508

Is there a mute mode on these? Is it possible to turn the volume to 0? Thanks
1 Answers
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- 1460

2 Answers
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 1371

from Phoenix, AZ asked:
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
1 Answers
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

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?
1 Answers
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

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
1 Answers
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

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
1 Answers
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. TL

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?
1 Answers
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

Our church wants to put a speacker with a volume controller switch in our nursery can you hook this up to a sound board??
1 Answers
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. TL/MA

Can I put 2 pair of speakers on 1 svc100?
1 Answers
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.

Does this control turn the speakers off the the volume is all the way down?
1 Answers
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.

Very Clean, Very Functional
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.

ConsDepth can be an issue

Nice unit for the price.
Had volume controls on my outddor speakers, but my indoor speakers are more efficient and I could not match the volume. No shop had a volume switch that came after the preamp. This is a great unit at a great price. Solved all my problems with volume.

Great prodct, great service
These controls work as advertised. The audio input and output terminals can be slipped off the circuit board for ease of connection. Inputs and outputs are clearly marked If you are in a commercial building like mine, some of the walls use 1/2 thick steel studs. There is not enough depth within the wall for the control. I added a surface box and all is well. I'd buy this product again in a heart beat.

This volume control is very easy to instal and use. The fact that it comes with multiple color plates is a bonus. The only drawback to I found is that the terminal block that the speaker wires attach to does not seem to attach well if you remove them to install the speaker wire.

I have three of these. Had a problem with two not working initially, but OSD replaced them with no questions asked. They work perfectly. The only reason I give 4 stars instead of 5 is that the color and size does not match perfectly with other decora wall plates. Since I have two zones outside I wanted a dual gang plate and had to modify one from HD to work. It looks OK though. Other than that issue, OSD makes excellent products and I have been very pleased with all my purchases.

Got six of these plus the six room selector. They work as good or better than Speaker Craft and Niles for $80 less each! Three different color plates is a huge convenience. Unreal. I was screwing in the speaker wires directly, struggling with the tight fit, and finally realized the connector base pulls off the pins. Makes screwing in the wires easer. Just plug the bases back onto the unit. Don't mix up the INPUT and OUTPUT labels if you do remove the terminal bases.

Always a pleasure dealing with these guys. I emailed some questions to them, before I tore out my walls, regarding how best to wire the house for audio. I received a prompt and explicit description of what I would need to complete the project. A year latter the walls are sealed and I have the best sound system on the block.
