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.

Hello I have a 1 pair of 8ohm OSD speakers running off of the "B" channel of my AV receiver which is rated 100+100 stereo at 8 ohms. I purchased a low cost volume control that was described as 100w and it ran fine as long as did not go past a certain level (34) and it would run for hours with out incident. However when I attempted to take it a little above that level (36), my receiver would activate "PROTECT". Note, I troubleshooted by bypassing the volume control to ensure it was not a line issue and I could run it past level 36 without tripping the protect mode. So either I have VC that is not 100+100 but 50+50 or I will need to get a higher powered VC. Can you please advise on the power specs and since I will be only running 1 pair of 8ohm speakers, what should the impedance be set at? If the VC IS underrated or I misunderstood the power specs, I will most likely turn my existing VC into a paper wait and purchase an OSD305R.

Hi Kidromel,
If your speakers are over 100 watts peak you should go with the OVC305R, which is more heavy duty that the 100 watt OVC205 R

I'm planning an install and I'm just wondering, what is the optimal gauge wire to use with these controllers? I'd like to run 12AWG or 14AWG wire, but I don't know if that's too large for the terminals on the controller.

Hi Tim,
The volume controls on our outdoor models are fully encased. There are small leads coming out of the bottom where you splice on your speaker cable. You are able to use a variety of gauges, including 12 gauge.

I want to use this volume control in my outdoor set up , but I have 12 AWG wire. Is it possible to use 12 AWG wire with this unit?

Hi Andy,
The outdoor volume controls have short leads that come out of the bottom where you can splice your 12- gauge wire.

I just received my OVC305R and the cables are mislabeled. There are two cables marked "LEFT OUTPUT." So I opened it up by removing the face plate, and confirmed which cables are output (top cables) and which are input (lower cables). Ok great. Now, how do I tell which are right and left and (+) and (-)?

Thank you for bringing this to our attention. Do both wires contain a red and black wire? If so, black will always be - and red will always be +. Feel free to call us at 562-697-2600 to discuss further. Thanks!

I have two sets of outdoor speakers (Bose 151s 40w 4ohm) being driven by a sony stereo amplifier (STR-DE185), One set of speakers is hooked up to the A speaker output and the other to the B speaker output, I wanted to have each set have it's own volume control so I hooked each up to tit's own OVC300 volume control. I was able to hook them up correctly, I think, but when turning the volume down, the amp shut off and went into protect mode. This happened with each setting 1/2, 4 and 8. This didn't happen until I hooked up both the left and right speakers. Right only worked fine.
Since each volume control is driving only one set of speakers would I be better off with the OVC305R?
Thanks,
Marc

Hi Marc:
The correct setting for your two OVC300 should have been 4x for both. The BOSE speakers being 4 ohm need to be calculated as two 8 ohm speakers for each or (4) 8 ohm speakers total. When you connected two 4 ohm speakers to your SONY Receiver in the 1/2x setting and played both speaker A & B at the same time the amplifier saw a 2 ohm load which caused it to shut down. Changing to the OVC305R Resistor type volume control which has no impedance protection would create the same scenario as the 1/2x. Check to make sure your wiring is correct for each Volume Control, Inputs connected to the Receiver and outputs to the speakers.
Did your Receiver shut down or get hot when you played the two pair of speakers connected directly to the A & B without Volume Controls?
