Features and Specifications:
With a whole-house audio system, you’ll enjoy great sound in the rooms you choose, but one person may like to shake the roof off while the other likes it mellow. That's where volume controls come in very handy. OSD Audio’s wall-mounted volume controls are an affordable, easy way to control speaker volume independently in each zone. Whether you choose 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
• Soft-touch slide attenuation
•Fits in a standard gang box; measures 4.125cm W x 6.35cm H x 6.35cm D
• Installation materials included


A Little about Volume Controls
Not every installation will require an impedance-matching volume control but it's important to know when you need it. 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 volume controls provide more precise protection for the amplifier/receiver versus the protection built into the speaker selector. In fact, 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.

Questions and Answers:
By Doug from Roy, Utah on January 6, 2012
I have 4 ceiling speakers (2 pair), do the speaker wires (8) hook into this controller and then do wires go out to the receiver? I guess the real question is how does the whole hook up work?
By Customer Service - Q&A on January 6, 2012

Answer:
Doug,
You would splice this is in-line where it fits best. The input would be from the amp/ receiver, and then through the output -to the speaker. Our volume controls have four inputs and four outputs. It works great for a pair of speakers. Note: Putting more than one pair per volume control is not recommended by OSD Audio for the novice user.

Will this work with Sonos ConnectAmp? Would I need to make any changes?
If I have two zones connected to a single AMP; would having one turned down and the other on cause any issues?
By Customer Service - Q&A on July 9, 2012

Answer:
Hi Mark C:

You should have no trouble connecting two VMS100 to your SONOS connect AMP. Make sure Impedance Setting is set to 2X. A Volume Control is an attenuator that adds no gain. When you turn down the volume in one zone the Volume control diverts the current to its transformers. The amplifier is still outputting to each volume control. Just understand that the VMS100 is not to be used as a on/off switch. That is usually accomplished by adding a speaker selector like our IS4 which features dedicated on/off switch per zone. You could even add two additional pairs with volume controls if needed and still have no problem.

By Pete from Phoenix on July 16, 2012
I have one sonos system that controls three rooms, two adjacent on the first level and the third in the basement. The speaker selector is on the second floor of the house (three floors away from basement) and it is impedance matching. Since I can't turn off the impedance matching for just two zones on the speaker selector, can I turn it off on the volume controller? Just want this in basement so I don't have to have it on down there (bedroom in basement as well).
By Customer Service - Q&A on July 17, 2012

Answer:
Hi Pete,
The VMS100's lowest setting would be 1/2x. Switch your volume controllers to this setting and this will disable the impedance matching so your speaker selector can take over.

By MarkC from Houston, TX on July 18, 2012
Since connecting the 2 Volume Controls to the Sonos ConnectAMP, I have noticed that the audible volume is lower than without the volume control connected and the ConnectAMP at the same volume as previous. What could cause this?
By Customer Service - Q&A on July 18, 2012

Answer:
Hi Mark,
These are impedance matching volume controls, that does take away slightly (less than 10%) from the power handling the speaker receive. You should make sure the settings on your two volume controls are at the lowest 1/2x to minimize the power loss.
CL
By Customer Service - Q&A on July 20, 2012

Answer:
Hi Mark:

The primary function of an impedance matching Volume Control is just that, to control the impedance matching (mainly to protect the Amplifier/Receiver). This is a passive device that does not add any gain. In effect you are not turning the Volume up but Attenuating the Volume Down. As you turn the volume down the signal is diverted to the transformers causing a bit of a load that ultimately drains power or volume compared to when you use no volume controls. So you will find you need to increase the volume level of the SONOS to higher settings to achieve the same volume level that you get without the volume controls.

This volume control does not have an Off switch, but the SVC205 does.
CL
By Customer Service - Q&A on January 31, 2012

Answer:
Hi Jim,

Most of our Transformer style Volume Controls do not disconnect even if they are turned all the way counterclockwise. They may be inaudible but there is still a connection. We do offer the SVC205 Impedance Matching Volume Control that features a true on/off switch. Unfortunately, it is not available in a slider style. We do offer a resistor-based volume control that is a "Break before Make" design that does completely disconnect when turned fully counterclockwise. This is not Impedance Matching but it has a broader Frequency Response and may offer a little better sound quality than the transformer based.

I have 16 units of your VMS-100 slider. How many speakers can control 1 VMS-100? My speaker is 20 watts to 100 watts 8 ohms.
By Customer Service - Q&A on July 25, 2012

Answer:
Hi Jose,
Our volume controls have 4 inputs and 4 outputs, meant for a pair of speakers. One left and one right. The only way you can add more to one volume control is by wiring in parallel, which we don't recommend for the novice installer.

By Jed from Minneapolis on April 17, 2012
Will this volume controller work with the SPW-8 Eight Zone Speaker Distribution Panel.
I will have 5 pairs of speakers with a Sonance 2120 AMP. 120 watt per channel x2 8 ohms.

I was planning to use a VSM 100 volume control for each pair of speaker. Speakers will be max of 125 watts.
By Customer Service - Q&A on April 17, 2012

Answer:
Hi Jed:

Yes these will work perfect with this setup. You will need to set the impedance to 8X for each Volume Control. That will insure your Sonance Amp sees a workable impedance load.

Product arrived as promised, a stock out meant that the item was upgraded to 300 series to meet delivery promise and allow me to finish the job. The coils on the unit arent bulky so they are easly to slip into a standard gang opening versus other mfgers units. A great unit for multiple pairs of speakers in one house.

Sticky Sliders but still Pretty Darned G
February 28, 2012
I bought 12 of these. I love the way they sound and in general I would say I am very pleased. The only negative is that the Plate and Slider mechanism doesn't slide very smoothly. It tends to bind. I see this on all of them. Now I don't adjust them terribly often so it's only an annoyance but if you are REALLY picky you might want to consider the dial type.
Pros:
Sound Quality, Easy To Use, Quality Construction, Easy To Setup
Cons:

Great volume control
August 10, 2011
For the price I was really impressed at the quality of the construction of these units. You cannot tell the difference from the higher end volume controllers that cost over $100 each. Here are my Pros: - I like the slider because I don't have to worry about a house guest over rotating the a knob and damaging the controller. With a slider you can instinctively look at it and tell the range of travel and at what volume level the unit is at from across the room. Which is great if you have kids who like to play with knobs all the time. - There is zero audible static, clicks or defects through the sliders range of adjustment from your speakers when making adjustments. - Love the removable plugs that allow you to hookup your in wall wires without having to dangle the entire unit from a few wires while you complete install. You get a removable plug for both your source and to your speakers. wire the plugs then connect to the controller and screw in place. Love that! - The built-in impedance selector is great as well so if you don't want to buy a separate speaker selector you don't have to worry about damaging your amp. The only two minor complaints I would have are: 1. The white face plates on all of mine were not truly white so they don't completely match standard white face-plates you get at you local hardware store. The did all match one another, just not a pure white which is noticeable to obsessive compulsive people like me. On the plus side you do get multiple color plates to suit your home decor. 2. The slider does not have any noticeable detent's in its range of travel which is very good. But on the negative side as you are adjusting the slider there are very small 'deadbands' or spots where you don't get any volume adjustment for the small amount of travel you put in. Again not a major issue as you still get a linear range of volume adjustment over the full range of the slider, just a few spots where it kind of stutters I guess. I bought 6 of these through out the house each one powering a pair of 8" in ceiling speakers and terminating at the OSD 150w amp. I couldn't be happier with their performance and quality and this is my volume control of choice going forward.
Pros:
Easy To Use, Multiple color face plate, Easy To Setup, Removable wire plugs, Quality Construction, No detents in slider rang
Cons:
White plate not true whit
Best Uses:
Whole home audio
