SKU: OSD-VKR-120
OSD VKR-120150W In-Wall Knob Style Resistor Base In-Wall Volume Control (White, Almond, Bone)
Resister-based volume controls like our VKR120 are often used with multi-channel amplifiers and impedance-matching speaker selectors. This is not an impedance matching volume control and features optimized sound quality with minimal low end roll off due to high permeability steel utilization. The VKR series of transformerless volume controls offers the widest frequency response of any volume control on the market today with virtually no high or low end roll off resulting in audiophile sound quality. Other features include two ounce double-sided G10 glass epoxy PCBs, a non-shorting design utilizing a "make before break" switch which prevents the amplifier from ever seeing a dead short and 12-14 gauge solderless speaker terminals with easy top termination. Every volume control includes a color coded knob and mounting screws.

Would the VKR120 work well with Sonos "Connect Amp" or "Amp" products? My current in wall impedance volume controller has very poor what i would call "volume ramp up". In wall controller at 100%, within the volume control on the Sonos controller at 50% the volume is still very low.

Hi Steve:If you are connecting directly from either the SONOS Connect AMP or the new SONOS AMP, you will not need Impedance matching volume controls. The SONOS Connect AMP can handle two pair of 8-ohm speakers (4-ohm load, each with a VKR120 connected inline). The SONOS AMP claims it can connect three pairs of 8-ohm speakers in parallel (2.6-ohm, each pair with a VKR120 inline). You know these are passive devices that attenuate the sound level from the Source. You are no adding any gain, just turning the sound down (counterclockwise). The VKR features a "Break Before Make" design. They disconnect between clicks, and unlike the Impedance Matching Transformer type Volume Controls, it disconnects when the rotary knob is turned all the way counterclockwise until the last click. The Resistor based Volume Controls do have a Broader Frequency Response with no high, or low end roll off. A good choice.TL/5597
