SKU: OSD-OVC300-PAR
OSD OVC300300W Rotary Outdoor Volume Control, Impedance Matching and Weather Resistant, White or Grey
Unique easy-access impedance matching jumper setting without open the weatherproof seal box. If you enjoy an outdoor audio system, you'll love the convenience of outdoor volume controls! Now you can stop dragging the remote control outside where it is sure to get lost, or avoid having to get up and go to your audio source to turn the volume up or down. This pure resonance volume control offers 300 Watts of optimized sound quality with minimal bass roll-off. Control 1-8 pairs of speakers simultaneously with impedance matching. The autoformer design features outstanding sound quality due to high permeability steel utilization in the volume control core. Comes with Grey or white face plate. In addition, the OVC-300 includes an easy access impedance switch that lets you set the impedance without opening the box.

I currently use Sonos Amps to power my outdoor speakers, would I be able to insert these inline to act as an additional physical volume control?

HI Steve:
If you are just connecting to a single pair of speakers per each SONOS Connect Amplifier (assuming you have more than one). I would recommend the OVC305 Resistor based Outdoor Volume Control which would feature your best sound quality (broader frequency response with no high or low-end roll-off inherent in auto-former style VC) and when you turn the volume knob all the way counter-clockwise you disconnect the signal (full off). This Volume Control has no Impedance matching so you are limited to a single pair of speakers connected to the SONOS Connect Amplifier. If you have 2 pairs of speakers connected I would recommend using our OVC300 Outdoor Impedance Matching Volume Control and connecting the two speakers in parallel after the Volume Control and setting the impedance switch to 1/2X. Note these Volume Controls are passive devices (both Resistor and transformer based) with no external power supply. They attenuate the signal (turn the signal down, no gain added) from whatever volume level you have set on the SONOS Connect. As you turn the knob counterclockwise the signal is diverted into the Autoformers on the back of the Volume Control so eventually, the sound becomes inaudible. It does not fully turn off even though you can no longer hear it. Most of our application use these Impedance Matching Volume Controls with a Speaker Selector which has a dedicated on/off switch per each zone. Bottom line no problem adding one of our Volume Controls just pick the one best for your application. If you need further clarification based upon your system setup; tim@osdaudio.com

I am currently running an Onkyo TX-RZ820 in the house and am looking to have the Zone 3 pre-out feed an AMP300 that will drive either three or four pairs of outdoor 8ohm speakers. My desire is to have a volume control for each pair of speakers and was wondering if it was more appropriate to go with either the 100W or 300W OVC?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Robert:
Always better to go big, pick the OVC300. These are passive devices that attenuate the volume not add gain. The way they work is when you are turning down the volume the signal diverts into the transformer (one for the right channel and one for the left channel). If the transformer is not big enough it will saturate the transformer before the signal is inaudible causing the signal to distort. The myth is if you turn the volume control down to where you do not hear the music anymore then the Volume Control must have turned off. So you have an active signal still diverting into the transformers. This why we recommend turning the zone off with the on/off switch of the Speaker Selector especially if not planning on listening to that area for any length of time.

Hello,
I would like to have 4 speakers wired throughout my patio. My stereo has two channels available and my stereo operates with 8ohm impedance per channel.
I was thinking if I could have two 8-ohm speakers connected and series (16-ohms) and use this for impedance matching (using 1/2x setting) back down to 8ohms to be able to connect to my receiver? The same would be done with the other pair of speakers.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Speaker-King:
Typically we recommend using the Impedance Matching Volume Controls with no more than two pairs of speakers before having to add a speaker selector and dedicated Volume Control to one or two other pairs of speakers. In reality, there are three settings on each Volume Control, 1/2X, 4X, and 8X. These numbers signify how many 8-ohm pairs connected in parallel to the Amplifier/Receiver. In your case, if you combine the two pairs of 8-ohm speakers in parallel to the outputs wires of the OVC300 and set the Impedance Matching switch to 1/2X, the Sony Receiver will see an 8-ohm load at the Speaker B output connection (Right and Left; +/-). I am assuming you have a pair of 8-ohm speakers connected to Speaker A Output of the SONY. So if you were to wire the two pair of speakers directly back to speaker B bypassing the SVC300, the Receiver would see a 4-ohm load which by itself might not be a problem unless you decide to play both Speaker A and Speaker B at the same time. Note, this would cause a 2.6-ohm load, under the 4 -ohm safety limit. You certainly can add a second OVC300, one to each pair of outdoor patio speakers it would most likely present a little safer load to the SONY. Another option for you to check out would be our SSVC2 2 zone speaker selector with individual Internal Impedance Matching Volume Controls per each channel. That would be installed right at the SONY Receiver. So you have three choices, 1) a single OVC300 wired to the two pairs of 8-ohm speakers, 2) 2 OVC300 one for each pair of 8-ohm speakers with both OVC300 wired back to Speaker B and connected in Parallel or utilizing the SSVC2 and wiring one pair to Zone 1 and the second pair to Zone 2.

Note: The AP550TT is a single stereo Dual Voice coil speaker that would not work for your application.

I have similar volume controls to run stereo pairs around my workplace, but if I wanted to run a pair of patio speakers with an outdoor subwoofer, how would I control the volume for both the subwoofer and the speakers with this volume control?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Rich:That is a tough question, what Subwoofer and Satellite speakers do you have? Do have the product already or trying to figure out what to buy? If you have a subwoofer/satellite system where you are running a full range signal to a subwoofer with built-in low pass crossover and high pass output to your satellites, then the OVC300 would go in-line before the Subwoofer. We do have an SSVC2 dual source, dual zone speaker Selector that would work but is more for indoor application and I am thinking you are looking for an outdoor option. I want to discuss your system further; tim@osdaudio.com. I am curious about your whole system; we have some new wireless options that would allow you to control your volumes from your Smartphone or tablet.TL/5584

Hi,I am interested in this producgt,1) do you ship to Canada2) can the input and output wires be connected to the board directly and not be tied to the wires shown in the photos?Thanks
Customer Service • 12/17/2019, 2:17:43 PM
Hi Siavash:I believe you can check on our web site and see if it gives you an option to ship directly to Canada. Or contact our customer service at 1-562-697-2600 ask for customer service.The Design does not feature input and output connections on the circuit board like the in-wall versions of our Volume Controls. The input and output cables are connected directly to the internal circuit board.TL/5595
