    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 100 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-100 includes an easy access impedance switch that lets you set the impedance without opening the box.

    bill • 12/17/2019, 2:17:43 PM Can any of your outdoor volume controls be used on a 70 Volt system? (instead of 8 ohm)
    Customer Service • 12/17/2019, 2:17:43 PM
    HI Bill: We do offer dedicated 70Volt mono Volume Controls. The 8 ohm versions do not work for the High impedance systems (25V, 70V or 100V). They are listed under Amplifiers & Electronics/Volume Controls/70V Volume Controls. TL
    Steve • 12/17/2019, 2:17:43 PM I have this volume control about 1ft away from the left speaker, and the right speaker is about 20ft away. The right speaker have virtually no volume at all. I can her it if I put my head right up to it. I swapped speakers left to right and still the right speaker isn't getting any volume (confirming both speakers are good though). If I move change the balance on the amp to all left I get pretty much the same thing (as expected, all sound coming from the left speaker) but if I put it all the way to the right I get nothing. Again, putting my head up to the right speaker I just barely hear it. I have the volume control at the default jumper setting. Would changing it fix the problem?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Steve: It sound like the Volume Control is the culprit.You should also contact us about upgrading to the OVC300. When the Volume Control is open all the way fully clockwise you should have equal output per each speaker. When you start attenuating the signal lowering the volume if the Volume control is rated too low it saturates and tends to distort at low volumes. So a new 300 watt Volume Control might be the ticket. Please contact to discuss your options (tell him Tim sent you). Good luck TL #1237
    Anson • 12/17/2019, 2:17:43 PM What do i set the jumper to if i installing 2 Def Tech AW6500 to a Denon avr-2309IC or possibly one speaker
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Anson, I would recommend stepping up to the OVC300. You would set Impedance to 1/2x the lowest setting for your one pair of speakers coming off the Denon receiver at 105 watts per channel. CL 1250
    John F • 12/17/2019, 2:17:43 PM I have 3 sets of outdoor speakers running off of a Phoneix Gold ISM4 splitter. I would like to install volume controls over these 3 locations. 1) If a speaker is rated "4-8 ohms" what setting should that control be. 2) The 2nd set is 8 ohms. What would be that setting, independent of the other two? 3) Not sure what the 3rd set is, probably 4 ohms. I am assuming each selector would be set independent of the others?? Or all 3 must be considered when setting the selectors for the 3 different speakers sets over different lines.
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi John, You set the impedance in correlation to the number of 8-ohm pairs you are running. Since 4-ohm speakers count as two and based upon two 4-ohm and one 8-ohm, set it at 4x or 8x (depending on what amp you are using). If you are using the PG AMP100 (equal to our AMP120), then set all to 8x. If you are using the PG AMP210 (equal to our AMP200), set all the volume controls to 4x. The protection should be OFF on the ISM4, because the volume controls are doing the impedance matching and you do not want two components trying to match the impedance. We recommend the OVC300 for 4-ohm speakers as it is designed for heavier loads. CL/MA 1939
    Don • 12/17/2019, 2:17:43 PM I am ordering the AP490 patio speakers. Will this control work with these speakers?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Don, The OVC100 outdoor volume control is a great match with our AP490 patio speakers. CL/MA 1975
