    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.

    Tim • 04/23/2023, 3:49:20 PM Will this (or one of the other volume control options) work with the BOM 4.1.2 and LS2 speakers? Thanks

    Hi Tim: The OVC305r would work best. You connect one to each of the four conductor outputs. The OVC305r does not have or need Impedance matching protection. Two eight pairs of speakers can be wired in parallel. Or one 4-ohm speaker. The other advantage the OVC305r has over the OVC300 is that it will disconnect completely when the knob is turned counterclockwise until it stops (turn off). Tim L 5/2023

    Rob • 12/04/2023, 6:01:22 PM How would I control a centrally located outdoor subwoofers volume level while using 3 outdoor full range speaker pairs with OVC300s on each pair to help fine tune the outdoor levels as to not annoy the neighbors. That is when I turn down the full range speakers volume using the OVC300 how can I have it so the subwoofer volume tracks this sound level reduction?
    Customer Service • 01/10/2024, 2:35:23 PM
    Rob: Connect your Sub amp in line with your primary speaker pair. It would be best to access the volume control wiring before the Sub amp High Speaker Level inputs (R&L +/-). Using the Speaker Level outputs, the sub amp would connect to the primary pair. The subwoofer would connect to the Mono speaker outputs of the sub amp. The speaker input and outputs work even if the sub-Amp is turned off. You will have more control over the volume of the Subwoofer by utilizing the Gain control on the Sub Amp. The master signal volume level would be controlled by the OVC300 equally between the SUB and the pair of speakers. There are a lot of variables or unknown aspects of your actual system. Please don't hesitate to let me know if you need further clarification.
