Easy to install in a standard single-gang box, it ensures low distortion and a flat frequency response for an immersive listening experience. ## Description Designed for whole house audio systems, OSD Audio’s VMS100 is a heavy-duty yet decorative impedance-matching volume control that is ideal for adjusting the volume of a pair of speakers independently in various rooms of your whole house audio system. Rated at 100 Watts peak with minimal bass roll-off, the VSM100 includes adjustable jumpers to add up to eight pairs of 8-ohm speakers simultaneously depending on what type of load your amp can handle, and the impedance-matching feature helps stabilize the ohm load going back to the amp or receiver to avoid overheating. A complete volume control kit that fits into a standard single-gang box, this kit includes the volume control, 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 VSM100 provides a ruler-flat frequency response while the 12-step slider offers noise-free volume control and a wide range of listening volumes.SpecificationsPower handling: 100W per channelFrequency Response 20Hz - 20kHzFront-mounted switch allows for easy adjustment when multiple pairs of speakers are connected to a single receiver oramplifierImpedance matching for 2, 4 or 8 pairs of speakers and can be used as non-impedance matching if leaving default onjumper setting at 1X.Steps: 12 (make before break)Total Attenuation: 42 dB (Max)Includes White, Ivory and Almond Plates, Inserts and KnobsFits in a standard gang boxMeasures 4.125cm W x 6.35cm H x 6.35cm D5-yr warranty Review: Works as promised and easy to install. - The speaker volume control works exactly as promised.

The screw terminals for attaching input and output wires increased the ease and flexibility of installation. The unit fits in a typical single gang box. I used the slider volume control in an external box to control outdoor patio speakers. The controller came with four face plates of different colors which are more than similar products from other sources. ### ⭐⭐⭐⭐⭐ RV Volume Control *by M***H on 4 August 2017* Works great for RV exterior speakers. No more in and out to adjust volume. ### ⭐⭐⭐⭐⭐ Great Value, great sound, great quality *by B***S on 1 October 2025* Easy to install, just make sure to give some slack on the wires you’re feeding in. It operates exactly how I needed it to, as I have my receiver inside in my basement, and wanted to control the volume of my outdoor speakers outside. Didn’t sacrifice any sound, the music quality is perfect with no interruptions, there is no lack of power to the speakers with this (I am running 75’ of speaker wire), and the look is what I expected. Great value compared to overpriced alternatives ## Frequently Bought Together - OSD 100W in Wall Volume Control Impedance Matching for Home Speakers, Slider White VMS100 - Micca M-6C 2-Way in-Ceiling Round Speaker, 7.6" Cutout Diameter, Whole House Audio, Home Theater, Indoor or Covered Outdoor, 6.5" Woofer, 1" Tweeter, White, Paintable, Each - Micca 6.5" 2-Way in Ceiling or Wall Round Speakers, 4 Pack, 6.5 Inch Woofer, 8" Cutout Diameter, Low Profile Rimless Design, for Indoor Rooms or Covered Outdoor Porches, White, Paintable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/558013553-osd-audio-vms100-impedance-matching-100w-in-wall-slider-style](https://www.desertcart.tn/products/558013553-osd-audio-vms100-impedance-matching-100w-in-wall-slider-style) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
