Features & Specifications

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.

Specifications

Other Product Info

There are two types of volume controller - Impedance matching and Non-impedance matching. If you connect your speaker parallel to the receiver or connect the speakers into an impedance protection speaker selector, use impedance matching volume controller. If you connect just one pair of speaker directly to the receiver or your speakers are connected directly into an impedance matching speaker selector, use regular volume controller.

When OSD entered the volume control arena, they choose to make the best sounding volume control with the widest frequency response and the best all around value on the market. The VKR series transformerless volume controls are the net result. They offer 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. This is a statement that no other manufacture can claim with their autoformer volume controls.

This Audiophile quality volume control is best to use with speaker selector or multi-zone amp. It is not impedance matching volume control. It features optimized sound quality with minimal low end roll off due to high permeability steel utilization. The VKR120 controls feature impedance matching capabilities and removable connectors.

All of the OSD volume controls feature two ounce double-sided G10 glass epoxy PCB’s, 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, Decora(r) metal/plastic insert and mounting screws. All Phoenix Gold volume controls will install as follows in single gang boxes from 18 to 14 cubic inch, except VKR120 with not fit a 14 box; double-gang in all 32 cubic inch or larger boxes; and triple-gang in all 42 cubic inch or larger boxes.

QUESTIONS & ANSWERS

By Jax from manhattan on September 9, 2012
If I have the DSM4 with the Impedance protection enabled , should I get this VKR120 resistor based VC or should I still just get the SVC300 and set the jumper to 1x? What is better for my setup thanks.
By Customer Service - Q&A on September 14, 2012

Answer:
Hi Jax,
Setting the SVC300 at 1/2X would not be using the impedance matching. If you are running the protection on the DSM4, then you don't need impedance matching on the volume control. For an ideal setup, it's best to keep an even setup with the zones/volume controls so 4 zones equals 4 volume controls. The question is: what is the power handling of your amp and speakers. The SVC300 can handle up to 300 Watts; the VKR120 can handle up to 150 Watts. Hope that helps!

Can I branch two ICE640TT stereo speakers in this? if not which volume control I should buy if I have 2 stereo speakers to put in one volume control unit...tkx
By Customer Service - Q&A on October 3, 2011

Answer:
Yes - you can use one volume control for two pair of speakers or in your case two single stereo speakers.

Please connect your speaker in "parallel" not in serial.

Does the lowest setting on the VKR120 completely turn off the speakers vs a transformer type VC simply making the sound inaudible.
By Customer Service - Q&A on December 23, 2012

Answer:
Hi Davis:

The VKR120 is a Resistor based non impedance matching volume control. These are a make before break design, so there is no connection between clicks and it does completely disengage when turned all the way counterclockwise. Depending on the setting of the master volume the control may become inaudible before the last click. But is not completely off until totally turned to the last click. The Impedance Matching Transformer style volume controls do not turn off at all except the SVC205 which has an actual on off switch on the plate below the rotary knob. Note the Resistor based volume controls in theory tend to sound better. There have no high or low end roll off meaning they have a broader Frequency Response.

The only volume control you should use.

These volume controls are audibly superior to any of the transformer coupled models we've used. MUCH tighter bass and cleaner highs.
Pros:
Incredible value at this price. Outperforms any v/c we've heard yet.
Cons:
You must pay attention to impedances. Use a switch with impedance protection if you are using multiples.

Delivers as promised...!!!!! MUST HAVE
April 14, 2014
I have been using volume controls from OSD for years with a multi-channel amp. So basically I have had impedance matching controls for no reason. I have always found them to be reliable, but noticed the lack of bass punch and the reduction in volume, even at the highest setting. I also noticed that with their HEAVY transformers, they always get hot....meaning some of my audio is being transferred into heat... NOT ANYMORE - these new Transformerless controllers are awesome 1. Compact and light - easy to fit into wall boxes 2. Crystal clear sound 3. No volume loss 4. No bass loss 5. NO heat!!!!!! If you have your system set up with ONE TO ONE amp channel to speaker (so you don't need impedance matching), get yourself some of these. Especially if you are listening to audiophile quality on audiophile speakers. The difference is VERY noticeable. I also have not found ANYONE else selling a controller like this. I also must add that OSD really stands behind their products. Over the 10 years I have used their stuff, I have occasionally had a volume controller (the old ones) die on me (note that I have bought over a 15 of these over the years) and OSD has replaced without any problems. A great store with excellent customer support!!!!!!
Pros:
See above... Light weight and compact Great Sound High quality build Easy to install
Cons:
None
Best Uses:
Multiroom setup with 1 to 1 amp channel to speaker

Great sound, TREMENDOUS value!

This resistor-based volume control "hit the mark" for me... quality construction, easy to install, nice looking on the wall etc. A nice feature is that it gives you the ability to completely "shut off" the speakers (disconnected/open circuit) from the amplifier... which allows you to leave the amplifier on for other zones without drawing current on an unused zone. I used this resistor-based volume control to replace a transformer type connected to a high-end set of Definitive Technology outdoor speakers. The sound platform has definitely changed in comparison to the transistor-based model. The high ends seem to come across better now!
Pros:
Easy To Set Up, Easy To Use, Quality Construction
Best Uses:
Upgrade, Replacement
