SKU: OSD-OVC305R-PAR
OSD OVC305R300W Resistor Based Weather-Resistant Outdoor Volume Control Rotary Style, White or Grey
This super sturdy, easy to install outdoor volume control can be used for one pair (two speakers). A pure resonance resistor-based volume control, it can handle up to 300 watts of optimal sound with minimal bass roll-off. The control board is prewired and the wires are clearly labeled, making installation easy, and this product can take the rigors of outdoor environments. You can use these along with one of our speaker selectors for a whole-house audio system at an affordable price.
Attention: This is not a impedance-matching type volume control.

I bought these volume controls, the wires are labeled input and output but does not inicate positive and negative, I used the wire with the sripe for neg and everything sounds terrible. Did I get the polarity wrong, please advise

trying to find out which wires are pos and neg have been waiting for response, your customer service is no service. you have been holding up my project and you make no attempt to return phone calls. I have left numerous messages, you have made no attempt to contact me!!!!!!!!!!!!!!!!!! very unhappy customer in houston

Brent,
I emailed you a diagram now. It goes on the LEFT + - (output) + - (input ) then on the RIGHT + - (input) then + - (output)

If the white stickers ripped of the wires, how can you tell the input wires to the volume control? Is this possible without opening up the control box? I can see one pair of the white/black wires says input but I do not want to assume the other white/black pair is the other input.
Thank you

Hi Thomas,
Please remove the faceplate of the unit by unscrewing the four screws and then remove the knob (it slides off). There is a rubber nut you must unscrew (we find it helpful to use a pair of needle-nose pliers for this). Take off the faceplate and press the wires in one by one to determine which set is on top. The top wires are the outputs. The bottom wires are the inputs. I will email you a picture of the OVC305R with the white labels so you can see which are positive and negative.

Is the lowest step 'off' on these or is it -36 thus leaving the speakers on? Description says 12 steps, brochure says 11 steps.

Hi Peter,
Thank you for pointing that out. The correct spec should be 11-step at 36 dB attenuation. At the bottom setting (all the way counter clockwise), the volume control is completely disconnected (off). The design of the resistor-based is “Break before Make” so there is no connection between clicks. On the upside, the resistor-based volume control has a broader frequency response and typically better sound quality; however, it does not do impedance matching.

The specs on the web page say:
-54dB, 12 step attenuation
Resistor Based
but the Product spec sheet says:
-36, 11 Step
for the OVC305R
Which is correct and does the lowest step turn the sound off?
