I have an onkyo tx-8050. I want to use the second speaker zone to power out door 8 ohms pop rock speakers. Not now but in the future I may want to add on speakers for out side obviously to a bigger receiver. Which volume control should I use and which gauge wire do you recommend. The distance from the receiver to the rock speakers would be roughly 150 feet

Hi Dan:
I would go with the OVC-300 for your current setup and for any expansion to your system. The higher power rating guarantees no distortion from over saturating the transformer especially at higher volumes. I would also recommend 14 gauge speaker wire for the distance you will be running the speaker cable. Also checkout our Aqua Blue direct burial terminating connectors.

I have a pair of rock speakers (insignia NS-R2111 - 8 ohms) connected to A Pioneer VSX--1130 audio receiver (6 ohms). When I use this volume control, I need to CRANK the receiver up to the MAX and have the volume control cranked up to the MAX.....and then I still only get minimal sound coming out of the speakers. Could this have anything to do with this volume control switch?

Hi Nick:
A couple of issues, you have a 7.2 Audio Video Receiver that has no pre-amp or speaker level output for a second Zone. What else are you connecting to the Receiver? Have you tried bypassing the Volume control and connecting the speakers directly to your output? When you say you have the Volume set to max I am assuming you mean fully open where you are not diverting any signal to the transformers? These are passive attenuaters that do not add any gain to the signal, you are actually turning the signal down as you turn the knob counterclockwise stepping the signal down 3 to 6 db at a time (per click). What is the Impedance setting you selected? I would be curious to hear how many speakers you have connected in total? Please feel free to respond to my email at tim@osdaudio.com.
Thanks in advance

I have 12 gauge direct burial speaker wire to my 100W outdoor speakers around 125 feet from the receiver The manual for this volume control says 14-16 gauge. Will this be a problem, or do I risk damage?
Customer Service • 12/17/2019, 2:17:43 PM
HI Scott:
No problem running a larger gauge wire in your system, you only run into problems when running too small a conductor like an 18 gauge over the same length, then you would be limiting the amount of current. In an 8 ohm setup you will experience signal loss when limiting the gauge of the wire for longer runs. We recommend a minimum 16 gauge up to 80 feet, 14 gauge up to 150 feet and 12 gauge above. If you are running wire for Sub woofer only then you will want to increase the 16 to 14 gauge above 50 feet and to 12 gauge above 100 feet. You do have to take in to consideration what components you are terminating the wires to. Most Volume controls and Speaker Selectors are limited to 16 and are tight on 14 gauge. The OVC300 is terminated to bare wire so will easily work with 12 gauge. Take a look at our Aqua Blue wire nuts ideal for direct burial. They feature silicon in the connector.
You are good with 12 gauge

I just received this volume control today. I didn't realize when I bought this volume control that it had pigtails. I was thinking I would run my speaker wire directly to the volume control. I have two questions: 1) if I wire my 12 gauge speaker wire to the pigtails coming out the bottom of the volume control, what kind of wire connector do you recommend? Having eight connectors in a 3/4" conduit will be tight, curious to your thoughts. 2) if I decide to wire my speaker wire directly to the speaker control, you unscrew the four screws on the cover, pull off the knob, but there appears to be a rubber gasket on the dial control. How do you remove that without damaging it so you can take off the cover? Thanks in advance!

Hi Scott:
The OVC Series of Volume Controls all feature hard wired input and output Color Coded Conductors. They are soldiered directly to the circuit boards, there are no removable connectors. Ironically most input and output connectors only accept up to 14 gauge and that is real tight so 12 gauge is better to be terminated with pigtails, now the new challenge how to terminate the 12 gauge to the pigtails with terminal cups that will fit into you 3/4" conduit/pipe. We do have our Aqua Blue weatherproof Electrical connectors with Silicon filling. You might be able to get away with smaller connectors since they will be in the conduit.
Good luck

is there any way to output 2 channel audio to two separate rock speakers with one volume control? or can this only handle 2 channel for one speaker? how would the wiring be set up?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Jim:
These are Impedance Matching Outdoor Volume Controls that provide you a couple of options. The Volume control is stereo with a left and right (+/-) Input and Left and Right (+/-) output. If you are buying it to power just two pair of speakers, no problem you just splice the outputs in Parallel positive to positve and negatives to negative. You just splice two right channels and two left channels. The internal Impedance setting would be 1/2x. There is also a 4x and 8X which are settings when you are connecting multiple Volume controls from a speaker selector. So if you have a four zone speaker selector with four pair of speakers, one pair per zone with a volume control then your would set the impedance to 4X on all four volume controls.
So yes you can connect up to two pair of speakers off a single OVC300 Volume Control.
