    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.

    Josh • 12/17/2019, 2:17:43 PM I only get audio if the volume control is in the fully on position. I do not get any audio on any of the lower volume settings. What is wrong?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Josh: That is a loaded question. It would help to know the following: What are you connected to Amplifier/Receiver and what speakers (Brand & Model)? How many Zones are you dealing with (Is this the only Volume Control you have). What is the impedance matching setting (look inside the 3/4" hole on the bottom)? You may have the Inputs connected to speakers instead of the Amplifier. It sounds like it could be reversed. TL/4655
    H P • 12/17/2019, 2:17:43 PM Hi I have a Onkyo 676 7.2 channel receiver. I will be using zone 2 for outdoor definitive technology 2 x aw6500 speakers. I just ordered 14 gauge direct burial in wall wire from your website. Do i need a separate/different wire? Or the wire i ordered and OVC100 will work for volume control? Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi HP: I am assuming you will be connecting the Zone 2 speaker Level outputs of the ONKYO Receiver. 14 Gauge will work perfect with the Onkyo, Definitive Technology speakers and OVC Volume Control. I would have recommended the OVC300 especially since the AVR is rated at 100 watts and the speakers will handle up to 200 watts. The OVC100 is rated at 50 watts RMS and 100 Watts peak so you would saturate the transformers before it could effectively turn down your volume to in-audible levels. You would want the OVC300. And checkout our Aqua Blue electrical connectors with silicon for terminating the speaker wires to the OVC 300. TL/4665
    Jeannette • 12/17/2019, 2:17:43 PM I have a JVC AX-R551 amp with zone 2 Driving 2 Bose 151 speakers. Old setup at fishing camp but would love to have volume control downstairs on those Bose speakers. Is the OVC 100 the correct choice for this application? And would like a recommendation for replacing the speaker wire. Thanks
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Jenette: The BOSE151 are rated at 10 to 100 watts and your JVC is rated at 100 watts per channel. You you would be better with the OVC300. It is rated at 150 watts RMS and 300 ways peak. But it will never saturate and distort because it will have ample storage capability. These volume controls attenuate your sound so in fact you are turning your sound down from whatever your source level is set to. You want to make sure you have plenty of room to divert the sound to the transformers. So the sound will be in audible long before it would saturate. TL/4762
    John Corry • 12/17/2019, 2:17:43 PM Can you provide any guidance on if the grey color of the box will match grey pvc pipe? Do you have any recommendations on a brand to buy that will match?
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi John: Good question, I assume we can find out the Grey Pantone and then you could contact the PVC manufacturer. I am also assuming our factory who has been doing this for ten plus years most likely used a PVC pipe as a reference. I will ask our engineer and post the results. TL/5054
    Barry • 12/17/2019, 2:17:43 PM We are in the process of building a pool and I am adding speakers outside under the eves. I have a Denon AVR 1913 receiver that will be located in the house. On each end of the house I am putting my pair of Klipsch AW650's (zone1). Part of patio is covered and under that section I am adding one Polk Audio Atrium8 SDI (zone 2). On the the far end of the pool I am going to go ahead and run the wire for a pair of 360 speakers, but I have not decided which brand at this time (zone 3). And while I am at it I may or may not run another zone for a sub. My question is will the OVC100 fit my needs? Since I am going to end up having at least three controllers, is there a cleaner, neater way to mount them together? I had thought about adding an elbow to each housing and then running them into one piece of conduit up to the attic, or I guess I could turn them sideways. They will be mounted on the stucco siding and have to be turned upside down to run back into the soffit since I am on a slab. Thanks for your help!
    Customer Service • 12/17/2019, 2:17:43 PM
    Hi Barry: I am assuming you are using the DENON Receiver for two-channel stereo mode. Are you using a speaker selector to separate your zones? The OVC100 is typically rated at 50 watts RMS and 100 watts peak. I would look at the OVC300 and make sure your impedance setting set to 4X for each volume control. Mounting the OVC300 sideways, upside down or right side up should not matter. It sounds like you want to have conduit connected to each volume control. The DENON does not have Zone 2 Preamp output, so I am assuming you combine all three zones to the front speaker outputs (or you utilize the surround, channel 4 and 5 and rear surround, channel 6 and 7 connections as well). Typically we would recommend something like our DSM4 four zone speaker selector which organizes your wires into parallel connections. It also features dedicated on/off buttons per zone. And the DSM4 features Dual source with dedicated A/B switches per zone connection. The OVC does not disconnect when turned counterclockwise to where you no longer can hear the music. It is still diverting the signal into the Transformers inside the waterproof box. The switch on the Speaker Selector disconnects totally. We have a 360 degree Omni speaker, the OS850. There are many outdoor subwoofer options we offer, and your DENON has a preamp output as well. TL/5508
