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.

The front clear outdoor cover for my volume control blew off. Can I get another cover or do I have to buy a whole new piece to install. The cover originally just lifted up from the top on hinges for you to access the volume control knob.

Hi Mary,
You would need to purchase a outdoor weather-proof box to get the cover part.

I have an 8 ohm Denon AVR-1913 stereo. I purchased 6 ohm deck speakers (Yamaha NS-AW150BL 2-Way Outdoor Speakers (Pair, Black) ) for Zone 2 on my stereo. The impedances do not match (my mistake). Can I buy the VKR120 Decora Volume Control and use with the pre-mentioned stereo and speakers? Thanks in advance for your help!

Hi Jon,
The VKR120 is a non-impedance matching volume control, so it will do nothing but send the power through from your amp to your speakers. That should be fine.

I have several sets of your speakers:
1 Ceiling Speaker with Dual OSD-ICE840TT Voice Coils OSD Audio ICE840TT
1 CeilingSpeakersWeatherResistantICE600WRS
1 CeilingSpeakerTrimless PairOSD AudioACE590Color white
2 Outdoor Speakers Patio OSD Audio AP520
I want to use the decor to adjust the volume on these speakers. Is this the product that I am looking for?
The 2 outdoor speakers may be in parallel at the source, with separate gang boxes outside. Would this also work?
Customer Service • 12/17/2019, 2:17:43 PM
You can use this if you have one for each speaker pair and one for the ICE840TT alone. Otherwise you would want to use something like the SVC300.

The box in my wall that I need this to mount in is a regular electrical box - 2.5" deep. It looks like this should work. Has anyone installed this in a 2.5" deep box?

Hi Chris:
I have been selling this Resistor based Volume Control design for over 20 years, no problem. You will notice the removable input/output connectors are 90 degrees from the front plate and not directly out the back. Making it easier to fit in Standard single gang J box.

Hi, I have a complicated setup. Bought 4 Klipsch R-1650-C speakers, 2 for 1st floor and 2 for 2nd floor.
1st floor Volume Control Setup: Has 4 speaker wires (1st & 2nd floors) and each wire has 1 Red and 1 Black wire. Also has a separate wire which goes from Volume control to Receiver with Red, Black, White and Freen wires inside this.
2nd floor Volume Control Setup: Has 2 speaker wires (2nd floor) and each wire has 1 Red and 1 Black wire. Also has 2 separate wires to connect to volume control and receiver with each wire having 1 Red and 1 Black wire.
Which volume control units should I buy to get the maximum usage?

Hi KK:
I would recommend our SSVC4 4 zone speaker selector box as your best option to connect all four pairs of speakers. I am assuming each pair are in a different room, two upstairs and two downstairs. And you do not already have volume controls in each room in line from the wall you show in your picture to the room, then to each pair of speakers. Typically you will connect the receiver to the volume control or in this case source A of the SSVC4 speaker selector with the four conductor cable (Red; R+, Black; R-, White; L+ and Green; L-) Then the two conductor Red and Black connects to the the left and right speakers in each room from either the Volume Controls or Speaker Selector's corresponding zone outputs (either zones 1, 2, 3 or 4). Your wires should already be labeled for each speaker. If not you can use a 9 volt battery to send a signal to each (you will need to have someone in each room to verify). The SSVC4 is ideal for your application since each pair of speakers would have a dedicated Impedance matching Volume control connected to it. It also features a second source input so you can add a second source switchable per zone (each zone has both an A/B and On/Off switch). Your other option is going with our SVC300 Impedance matching Volume Controls, one for upstairs (grey wires) and a second for downstairs (yellow wires). In this case you would tie the two right speakers wires (both reds together and both blacks together) and then both Left speakers as well. A single 2 conductor cable would then connect from the right conductors to the Right input of the SVC300. Do the same with the left conductors to the Left inputs on the SVC300. Do the same with your second volume control and your four two conductor cables from downstairs. You will have to split your four conductors black jacketed cable so you can run four conductors to each SVC300 inputs. You may notice the SSVC4 option does not need to any splicing or splitting of your existing wiring.
If you need anymore info, please contact me at tim@osdaudio.com. I could furnish you a diagram if need be but checkout the SSVC4.
Good luck
