OSD Audio’s VMS100 is an impedance-matching volume control for adjusting the volume of a pair of speakers within a whole house audio system. Ideal for dining rooms, saunas, porches or other areas of the house where you want to add sound, the VMS100 maintains the full hi-fi audio frequency response with no low frequency roll-off and is equipped with the same features of volume controls that cost twice as much. Rated at 100 Watts peak, the volume control includes adjustable jumpers to add up to eight pairs of 8-ohm speakers simultaneously, and the impedance-matching feature helps stabilize the ohm load going back to the amp or receiver to avoid overheating. This is a complete volume control kit that fits into a standard single-gang box and includes the VC, junction box, screws and assorted color trim plates (white, ivory and almond) so you can choose the color that best matches the room. Compatible with almost any dedicated audio zone or whole house system, the electronics inside the VSM100 are designed with a ruler-flat frequency response while the 12-step slider provides noise-free volume control and a wide range of listening volumes.

Features:
  • Decora style impedance-matching volume control for whole house audio systems and dedicated audio zones
  • Rated at 100 Watts peak with minimal bass roll-off
  • Impedance-matching helps stabilize the ohm load to avoid overheating
  • Accepts up to 14-gauge wiring and fits in a standard gang box with a depth of 2.9”
  • Includes junction box, screws and white, ivory and almond trim plates to match any room décor
  • Precision electronic design provides low distortion and a ruler flat frequency response
  • 12-step linear slider for pop-free control and a wide range of listening volumes
  • Installs easily and works with almost any audio system
What Is Impedance Matching Volume Control?
Impedance is a measurement of resistance to alternating current. Speakers are specified by impedance, and a common value 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. Volume controls such as the VMS100 have selectable impedance so you can 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. 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.

31 Questions asked on 100W Impedance Matching Decora Style Soft-Touch Slider Speaker Volume Control Kit - VMS100

Frank • 12/17/2019, 2:17:43 PM Q What if you have 3 pairs of speakers in the house. Where do you set the impedence control?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Frank, To clarify, does each of speaker pair have a direct run back to a speaker selector? Most speaker selectors have impedance matching to where you would keep the volume control at the lowest setting 1/2X. To help you further, well need to know more information, such as what amp/receiver you using. Can you also let us know how your system is wired? CL/MA 1317
Albert • 12/17/2019, 2:17:43 PM Q What are the dimensions?
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Albert, The VMS100 volume control will fit in a standard gang box and measures 4.125cm W x 6.35cm H x 6.35cm D. CL/MA 1696
Albert • 12/17/2019, 2:17:43 PM Q Is the VMS100 available in light almond, looks like it is one of three optiions in the picture but don't see an option for it in the ordering process? Thanks :-)
Customer Service • 12/17/2019, 2:17:43 PM
A Hi Albert, You dont need to pick a color. OSD Audio volume control come with all three colors in the package. This way you can switch it up if your decor changes because you will have spare face plates and knobs. CL/MA 1701
Jared • 12/17/2019, 2:17:43 PM Q Other vendor's volume control specifications note that they can only support 14 AWG wire, however I have 16 AWG wire. Will this still work with the VMS100?
Customer Service • 12/17/2019, 2:17:43 PM
A Jared, Yes. This volume control will work with 16 gauge wire. The only gauge it may have difficulty with is 12 gauge. Thanks. -BM 2261
Jason • 12/17/2019, 2:17:43 PM Q I have a 7.2 pioneer SC-63 with a DC3 amplifier amp that puts out 125 watts RMS per channel. I was wondering if this will fry the volume controller as it is only rated at 100 RMS power. I will have 4 pairs of speakers coming off a distribution box and a volume controller for each pair. thanks, Jason
Customer Service • 12/17/2019, 2:17:43 PM
A Jason, Will the 4 pairs be running off one channel or each pair has its own channel? In other words, will 125 watts be distributed into 4 pairs or will each pair have 125 watts? It may be safer to go with the VMS300. Let us know. Thanks. -BM 2367
