    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.

    shane • 12/17/2019, 2:17:43 PM I purchased a ovc300 I'm having trouble with the volume . I connected the wires on the receiver to the right and left speaker inputs positive to positive and negative to negative then I connected the speaker wires to the input side of the volume control in the same order, then i ran the speaker wires to the two speakers and connected the speaker wires to the output in the same order the two speaker sound don't sound right when I turn the volume up on the ovc300 the one speaker is louder than the other. when I turn down the volume one speaker you can't here at all.

    Volume control are designed to attenuate the sound (turn it down). You have to make sure the output from the receiver/amplifier is properly balanced and set to the maximum comfort listening level. This is when the volume control is turned all the way to the right (fully open with no attenuation). You can also bypass the volume control to make sure you have the balance and volume levels set properly. Also make sure you have set the impedance to 1/2X on the volume control.
    bruce • 12/17/2019, 2:17:43 PM will this unit work in stereo right and left ch.?

    Bruce: This is a stereo Volume Control with a left and right input and output, four conductors in and four conductors out (L&R, +/-). TL
    Bryan • 12/17/2019, 2:17:43 PM Can these be wired in series? I have speakers on the deck and then speakers in the yard/patio area. Sometimes I will want to turn the yard/patio area down and not the deck area or vice versa.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Bryan: Impedance Matching Volume controls are meant to be wired in Parallel. If you are connecting two volume controls from a single output you need to make sure the impedance setting on each of the OVC300 are set to 2X, if you had three volume controls it would be set on 4X. You can also add any of our ISS or DSM speaker selectors which are wired in parallel as well but add on/off capability and switchable protection if you were not using the volume controls. TL
    Mr. Pils • 12/17/2019, 2:17:43 PM I have a simple amp with a single set of speaker outputs for left and right currently connected to some deck speakers. I'd like to add some of your green tic/paramount style speakers to and adjacent patio to the same amp. I think I will always want both sets on, however, I would like independent volume control. I suppose if I want one set off I could just turn the volume to minimum. my question is, can I connect in parallel, using wire nuts to create two each left - + and right - + and then run one of each set to 2 seperate volume controls of this model? Then each volume control goes to its own pair of speakers? Is this dangerous for the amp? Or exactly what this device is made for? Is 1/2x setting the same as 2x or is there a discrete 2x setting? Based on other q&a 2x seems appropriate. Thanks, I love all the products to date. Whole house abus system at inlaws using 13 sets of OSD speakers is superb!

    Well need to know which amplifier you are already using for your existing speakers. If it is something like our AMP60 or even AMP120, you might have issues loading up two Volume Controls. Does your current amplifier feature a speaker A and B output? If you were using something like AMP200, you could easily use the Speaker A and Speaker B output to a Volume Control, then to the individual pair of speakers. That way you could also turn off either pair at the amplifier as well. The Volume Controls would be set to the 1/2x setting. Also for your new speakers that you want to add, checkout the OMSUB200 combined with the OS525 for a unique Sub-sat system. TL/MA
    Tommy • 12/17/2019, 2:17:43 PM how do you wire these up?
    Customer Service • 12/17/2019, 2:17:43 PM
    Tommy, Our voume controls can fit in anywhere between the speaker and the amp or receiver. They have four inputs and four outputs. You would put your speaker wire (like our 16-2 outdoor speaker wire found in the audio/ video cables section ) from the amp/ recever into the inputs of the OVC300 and then out from the outputs to the speaker pair.
