Matthew Tevald
from New Jersey asked:
March 31, 2019
My amplifier spec is 50 Watt RMS per channel at 4 ohms. I currently have 2 pairs of 8ohm speakers connected to it without any issues. Can I connect an OVC305R to control the volume of both speaker pairs?
1 Answer
Hi Matthew: The OVCR305R is a better choice versus the OVC300 as long as you do not need Impedance Matching. And that seems to be the case based upon your description. There is no high or low-end roll-off and a broader Frequency response, and unlike the typical Transformer style when you turn the knob fully counterclockwise, it shuts the Volume Control off. Another difference is this is a "Break before Make design" so there is no sound between clicks. The Break before make most notable when you have the master volume at its highest level and then start slowly turning the volume down. But this is all about listening to music and the OVC305R is a step up. TL/5480

In my setup I will have Yamaha RX-V377 Front L and Front R go to Steren 400Watt, 4 channel speaker selector then it will go to two Klipsch KHO-7 (75W min and 300W max) or room's 5.1 theater system. Will OVC305R work fine with speaker selector in the picture?
1 Answer
Hi Danny: The OVC305R would be your best match with the Steren Speaker Selector. Since the Steren has automatic internal protection you do not (or should not) use Impedance Matching Volume Controls. You do not need a volume control for each zone either. Normally if you use impedance matching volume controls you need to make sure all zones are covered and you use speaker selectors where you can defeat the internal protection so you are not double dipping. So the OVC305 R resistor based Volume Control is the perfect choice for one or two zones or for all four. TL/4911

I'd like to mount this in a recessed box in my exterior siding. I'd keep the faceplate, knob, etc. Does it come apart?
1 Answer
HI Doug: If you are placing this in a weatherproof box and don't need the Weatherproof housing then look at the VKR-120 which is the same Resister based Volume Control with removable face plate and knob. Good luck TL/4456

I am using a Niles SSVC-6 speaker selector with Selectable Impedance Magnification. I have six pairs of speakers connected and the impedance selector set to 6 pairs. In the backyard I have a pair of Yamaha NS-AW350W speakers. I want to put a volume control outside with the Yamaha speakers. I was wondering if the OVC305R Stereo Outdoor Volume Control would work with this set-up. Thanks for any help!
1 Answer
Hi Herb: The OVC-305 is an ideal choice for your application. The OVC305R is a resistor based volume control that has no impedance matching but does have a broader frequency response than it transformer counterpart. The Niles Speaker Selector will handle the impedance matching and the OVC-305 will just control the volume without limiting the high or low frequencies. The other advantage to the OVC-305R is that it is a break before make setup . You will notice the music does not play between clicks. But when you turn the rotary knob to full off the Volume control turns off and disconnects the resistors from the signal. Good choice TS-2271

July 10, 2012
The specs on the web page say: -54dB, 12 step attenuation Resistor Based but the Product spec sheet says: -36, 11 Step for the OVC305R Which is correct and does the lowest step turn the sound off?
1 Answer
Hi Peter, Hi Peter: Thank you for pointing that out. The correct spec should be 11-step at 36 dB attenuation. At the bottom setting (all the way counter clockwise), the volume control is completely disconnected (off). The design of the resistor-based is “Break before Make” so there is no connection between clicks. On the upside, the resistor-based volume control has a broader frequency response and typically better sound quality; however, it does not do impedance matching. TL/MA

from Memphis TN asked:
April 5, 2017
This will work for one pair of 6 OHM Yamaha's NS-AW150WH, correct?
1 Answer
Hi Michael: This is a Resistor based Volume Control that has no Impedance matching capability. The 6 ohm Yamaha's will show the Receiver/Amplifier a 6 ohm load. Which is OK if you are planning just to connect a single pair of Yamaha's connected to it. If you are planning to do multiples you will need a Speaker Selector that has good internal protection to handle the Impedance matching. Note, this are considered a little better sounding volume control with a broader Frequency Response with no high or low end roll off. It is considered break before make design so there is no connection between clicks so you have to be careful on your source volume levels when attenuating the sound with the OVC305R. TL/4290

Ken
from Mineola, NY asked:
July 22, 2016
I have a Denon AVR-X40000 receiver. Going to install a pair of Definitive Technology AW6500 outdoor speakers in my backyard under the eves of my house. the speakers are 8 ohm and can handle up to 200 watts each. I'm using Audioquest 14/4 speaker wire from the receiver to the speakers. Less than a 100'. Would like to hook up a speaker volume control outside. Which one would you recomend ? Thanks
1 Answer
Hi Ken: If this is your only pair of speakers you are powering so you do not have to worry about impedance matching then the OVC-305R (resistor based) volume control with be your best sounding option. It has a little bit better overall frequency response but no Impedance Matching capability that is needed for certain applications. The OVC-300 sacrifices a bit of sound quality but makes up for it with its impedance Matching capability. It is the same with our VKR-120 vs the SVC-300 both for interior use. So now the question is are you using this Receiver just for these pair of speakers. The amplifier features Front stage R & L, Front Height R & L and Front Wide R & L. It is a 7.2 Receiver with 11 outputs (7 standard and 4 additional effects) It does have Zone 2 and Zone 3 outputs but the are Pre-amp outs that would need an external Amplifier like our AMP 200. Interesting that it does assign the Front Wide R & L for 2 channel playback but you would not be able to have the Home Theater run at the same time as the 2 channels. You can only do that I believe when using Zone 2 or Zone three for three different sources available at the same time but again that would take external amps to power both ZONE 2 and ZONE 3. TL/3895

August 9, 2015
Would this control unit be sufficient if it was running to an OMNI Sub200 which connects to 2 Niles 6 1/2" rock speakers (RS6PRO) 8ohms? My receiver is a Sony 725w 5.2 channel (STRDH550). On my other channel I would be running a pair of Yamaha 6 1/2" 6ohm speakers (NS-AW390BL). Do you guys think this setup would work and have a good sound around a pool?
1 Answer
Hi Brad, That should be fine! Always good to run the volume control between the sub and satellite speakers so you can limit the volume on the satellite speakers, allowing you to turn up the volume to the sub to reach its full potential.

J. Brooks
from Nampa, Idaho asked:
July 27, 2015
I plan on running three pairs of outdoor speakers off of a Niles SI-2150 amp. All of the speakers will be the same make and model (have yet to decide which speakers we’ll go with, but they will be the same). The speakers will be wired in parallel bringing the impedance level down to a 2.67 ohm load at the Niles SI-2150 amp. Obviously all three pairs of speakers will be playing at the same time (which is what we want), however we want to have volume control on each pair of speakers to adjust the listening level as needed OR flat out shut a pair of them off. Will this OVC305R volume control work best for this application OR do I need to go with the OVC300 impedance matching volume control? Again we want to adjust the volume level of each pair of speakers independently from the others. Included is a rough idea of what I am planning on doing. Thanks!
1 Answer
Hi J, Is that amplifier high-current and able to run 2ohm loads? If not, it may be risky running that many speakers off of it. We have our AMP200 and AMP300 that are high-current and can run down to a 2ohm load per zone. If it's like that though, then either volume control will work, but you would have most power yielded with the OVC305 since it wouldn't absorb any power to activate the impedance matching.

Greg
from Boston, MA asked:
July 24, 2015
I installed the OVC305R connecting my Sony receiver B channel 6 ohms output to a single pair of Yamaha 6 ohms speakers. The right speaker only works when the volume knob is turned up to 9 or above. I've tried swapping speakers and re-wiring but it appears to be the OVC305R that is the problem. Any suggestions?
1 Answer
Hi Greg, It sounds like the issue could be that the volume on your receiver isn't loud enough. That's usually the source of the problem when the volume control starts acting strange. It needs power to run through it for it to function properly, and then you can turn the volume down via the volume control itself.

I have a pair of Pyle outdoor speakers rated at 200w RMS/400w peak each. The highest rated volume control I can find is 300w peak. Is there a product just like this one that is rated for 400w? If not will this be okay as long as I don't push the speakers to the highest volume? Or am I out of luck if I stick with these speakers? Thank you!
1 Answer
Sorry, not that I know of. Our max is 300wpc. Possibly could work if you limited the volume on your receiver so it's not pushing out so much power? Might want to talk to the manufacturer of the receiver to see what they recommend.

Hi Dan, The OVC305R can only handle 300 watts per channel max. I don't believe it would be safe to run with the amp in bridged mode.

Hi Joseph, Correct - the outdoor volume controls are only weather-resistant due to the box they are enclosed in. Removing the internal control from the box would make it susceptible to the elements.

I'm looking to purchase OVC305R to control a pair of TIC GS5's. I would like to flush mount the VC and faceplate into a standard electrical "bell weatherproof" box. Can this been done? I would flush mount the electrical box behind my outdoor siding to hide the conduit in the fireplace "framing"...
1 Answer
Hi Steve, I'm not 100% sure it will fit, but if it does fit it's definitely okay as long as it's weather proofed. You can remove the internal volume control from the box by popping the knob off, unscrewing the bolt, then removing the faceplate.

Marc
from Pennsylvania asked:
August 4, 2013
I have two sets of outdoor speakers (Bose 151s 40w 4ohm) being driven by a sony stereo amplifier (STR-DE185), One set of speakers is hooked up to the A speaker output and the other to the B speaker output, I wanted to have each set have it's own volume control so I hooked each up to tit's own OVC300 volume control. I was able to hook them up correctly, I think, but when turning the volume down, the amp shut off and went into protect mode. This happened with each setting 1/2, 4 and 8. This didn't happen until I hooked up both the left and right speakers. Right only worked fine. Since each volume control is driving only one set of speakers would I be better off with the OVC305R? Thanks, Marc
1 Answer
Hi Marc: The correct setting for your two OVC300 should have been 4x for both. The BOSE speakers being 4 ohm need to be calculated as two 8 ohm speakers for each or (4) 8 ohm speakers total. When you connected two 4 ohm speakers to your SONY Receiver in the 1/2x setting and played both speaker A & B at the same time the amplifier saw a 2 ohm load which caused it to shut down. Changing to the OVC305R Resistor type volume control which has no impedance protection would create the same scenario as the 1/2x. Check to make sure your wiring is correct for each Volume Control, Inputs connected to the Receiver and outputs to the speakers. Did your Receiver shut down or get hot when you played the two pair of speakers connected directly to the A & B without Volume Controls? TL-2122

kidromel
from Los Angeles, California asked:
July 25, 2012
Hello I have a 1 pair of 8ohm OSD speakers running off of the "B" channel of my AV receiver which is rated 100+100 stereo at 8 ohms. I purchased a low cost volume control that was described as 100w and it ran fine as long as did not go past a certain level (34) and it would run for hours with out incident. However when I attempted to take it a little above that level (36), my receiver would activate "PROTECT". Note, I troubleshooted by bypassing the volume control to ensure it was not a line issue and I could run it past level 36 without tripping the protect mode. So either I have VC that is not 100+100 but 50+50 or I will need to get a higher powered VC. Can you please advise on the power specs and since I will be only running 1 pair of 8ohm speakers, what should the impedance be set at? If the VC IS underrated or I misunderstood the power specs, I will most likely turn my existing VC into a paper wait and purchase an OSD305R.

Hi Kidromel, If your speakers are over 100 watts peak you should go with the OVC305R, which is more heavy duty that the 100 watt OVC205 R CL

If the white stickers ripped of the wires, how can you tell the input wires to the volume control? Is this possible without opening up the control box? I can see one pair of the white/black wires says input but I do not want to assume the other white/black pair is the other input. Thank you
1 Answer
Hi Thomas, Please remove the faceplate of the unit by unscrewing the four screws and then remove the knob (it slides off). There is a rubber nut you must unscrew (we find it helpful to use a pair of needle-nose pliers for this). Take off the faceplate and press the wires in one by one to determine which set is on top. The top wires are the outputs. The bottom wires are the inputs. I will email you a picture of the OVC305R with the white labels so you can see which are positive and negative. CL/MA
