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.

CB • 12/17/2019, 2:17:43 PM The specs say this control can handle 150w rms, the owners manual says 100w rms. Which is it? Is this rating Per Channel or Total?
Customer Service • 12/17/2019, 2:17:43 PM
Hi CB: Worse case consider that these are rated at 100 Watts Continuous RMS power with peaks as high as 300 watts. But really an Impedance Matching Volume Control's main function is to help to protect your Amplifier/Receiver from an unwanted loads. Secondary is to help adjust the volume levels. Note: all these Volume Controls are passive devices that attenuate the volume level. You set the maximum level then turn the sound down (turning counter clockwise) by diverting the signal current into the two transformers (Right & Left Stereo). It does not have an on/off setting so when you turn it down to inaudible levels it does not stop diverting the current into the transformer. To turn fully off hopefully you will have a speaker selector with an on/off switch or a speaker A or B switch on the Amp/Receiver. The OVC 300 Volume Control has the highest rated protection. I hope that helps TL/4013
Paul • 12/17/2019, 2:17:43 PM I have an Onkyo TX-NR545 and plan to hook up outdoor speakers to zone 2. I have two Klipsch AW-650 in the patio and two Klipsch AWR-650 rocks out in the yard. I'd like to be able to control the volume of the patio and yard separately. The AWR-650s are "true two-way" speakers meaning they have left and right channel speakers in each rock and have separate wires to connect them. So this ends up as three pairs of speakers. What would be the best wiring configuration with two OVC300's? Could I mix one OVC300 with the single AW-650 and another OVC300 with the AWR-650s wired in series or parallel?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Paul: I am assuming you are connecting these from the Speaker Level Zone 2 output. We typically do not recommend running multiple speakers off a zone two output but I would recommend connecting the the pair of patio speakers with the single OVC 300 and then the two Dual voice coil stereo rocks in parallel to the second OVC 300. Make sure you set the impedance setting to 4X. Check your receiver to see if it gets hot to the touch when playing both the patio and rocks speakers at high volume. The OVC 300's will do the impedance matching so your receiver sees a consistent 8 ohm load. Typically the Japanese Receivers will have relay that will shut down before there is any damage caused by a low impedance load. The next step would be to add a dedicated High Current amplifier like our AMP 200 and connect to the Zone 2 pre-amp output. Good luck TL/4029
John • 12/17/2019, 2:17:43 PM I have a Sony receiver with 8 ohm output. I plan to hook up two Dual Voice Coil Rock Speaker to the B speaker output I plan to use the OVC 300 volume control I plan to use 14-4 direct burial cable in plastic conduit The specs on the speakers are as follows: Contractor Series MR-8S 8 Dual Voice Coil Poly Resin Weatherproof Woofer 8 Poly Pro Woofer with rubber surround Tweeter Two 1 Mylar Tweeters Response 60Hz-20kHz Impedance- 8 ohm Max power - 120 Watts Sensitivity 90dB As my rock speakers are Dual Voice coil, they have a cable with 4 wires coming from them. How do you suggest I connect the two speakers (8 wires) to the OVC300?
Customer Service • 12/17/2019, 2:17:43 PM
Hi John: On our site there is an image on the SVC300 page that show the color scheme for the input and output wiring. 14/4 typically has Red, Black, White and Red jacketed conductors... 14/4 from Receiver SVC300 Input Red Right Positive Red Right Positive Input Black Right Negative Black Right Negative Input White Left Positive Blue Left Positive Input Green Left Negative Black Left Negative Input Note; all cables on the SVC300, both Input and output feature two conductor molded together with a black ground for all four choices SVC300 Output 14/4 x 2 (one 14/4 to each DVC speaker) Green Right Positive Output Red Right Positive Output to speaker Black Right Negative Output Black Right Negative Output to speaker White Left Positive Output White Left Positive Output to speaker Black Left Negative Output Green Left Negative Output to speaker Not sure what the conductors are on your DVC Rock speakers just connect corresponding right (positive and Negative) and left (positive and negative) to the correct inputs of the speakers. You will connect the two 14/4 cables in parallel to the output side of the SVC300, set impedance switch to 1/2x Let us know if that answers your question... TL/4041
Craig • 12/17/2019, 2:17:43 PM I'm trying to hook up a volume control with off switch by my hot tub outside. I purchased VC105 In-Wall Impedance Matching Volume Control with On/Off Switch and AL-DBPV1C Waterproof Box to Install In-wall Volume Control Outdoors. I'm wondering now if this OVC300 is what I should have purchased because I still need some type of outdoor box to install the switch in, then the waterproof box over it. I guess my question is, do you sale something that this vc105 switch will mount in so I can mount it to a post on my deck. I went to 2 different places today that sale electrical items and I struck out.
Customer Service • 12/17/2019, 2:17:43 PM
Hi Craig: The VC-105 is still your best option from us with the weaterproof cover; Check out waterproof boxes from Grainger: https://www.grainger.com/category/weatherproof-boxes/electrical-boxes-covers-and-accessories/wire-cable-and-carrier-systems/electrical/ecatalog/N-qri?okey=Weatherproof+electrical+boxes&mkey=Weatherproof+electrical+boxes&refineSearchString=Weatherproof+electrical+boxes&NLSCM=14&EndecaKeyword=Weatherproof+electrical+boxes&searchBar=true&searchRedirect=Weatherproof+electrical+boxes Good luck TL/4091 PS: One other option based upon how many other speakers you have connected in your system. If tis is your only pair of speakers or you are using a speaker selector with good internal protection you should consider the OVC 305 R White or Grey. It is a Resister based outdoor Volume Control that features make a break before Make design and does not have impedance Matching Volume Control but is better sounding and when you do turn the knob counter clockwise all the way to stop it is truly off.

james ackley • 12/17/2019, 2:17:43 PM I have a side by side with 6 speakers on the rear top behind me and when riding I could not hear the music so I turned 2 of the speakers facing me but now its too loud so I am wanting to control the volume of those 2 front facing speakers so as I can turn them down alone. What do you recommend? I am looking at the OVC300 Outdoor Volume Control Self-Impedance, What do you think?
Customer Service • 12/17/2019, 2:17:43 PM
Hi James: The OVC300 will work. I am curious what the rest of the setup is for you. Do you mean 6 speakers or 3 pair and one pair you want to add the Volume Control. Are you using a speaker selector and what Amplifier are you using? TL/4154
