I have a reciever with two sets of speaker channels A n B will it allow me to use all four at once?

New User U on Aug 2, 2020

BEST ANSWER: They may need to be the same ohms. I would say go ahead and try it. If it doesn't work or doesn't sound good just get another one and put one set on one control and the other on another control. You can locate the controls right next to each other so they are in the same location. Hope this helps.

The Monoprice OVC Rotary 300-Watt Outdoor Volume with Auto Impedance Matching is only designed to handle one pair of speakers. So if you intend to control Speaker Pairs A & B with an outboard volume control, you will need to purchase two.

Depends on how you wire the inputs. I have mine set for a set of outside speakers only. The rest of the speakers are on all the time.

I don’t think so. You can install a Bluetooth on your receiver and control volume with your phone.

I have two pairs of speakers running off one amp I need one of the speaker pairs to be louder. Will this do that for me?

A shopper on Dec 14, 2021

BEST ANSWER: I believe so - description states "allows you to connect multiple speaker pairs to a single power amplifier". I expect for your use case you would use one of these to make one of your speaker pairs quieter i.e. the amp is turned up, and you use this volume control to turn the other to a lower level or silent. Using two volume controls, you could adjust each speaker pair independently.

It will. Just tie this in mine with the pair you want to regulate and you can control their volume individually from the other pair

If you install it correctly it should lower the volume on one set.

is that 14 gauge speaker wire?

A shopper on Jun 12, 2022

BEST ANSWER: No, it is 18 AWG. Also be aware that the box is barely big enough for the wire and all the connectors. It was a long run to my outdoor speakers, so I used 12 gauge wire. It was a real struggle to get everything in the box. Would have been easier if I used 14 or 18 gauge, but I felt like 12 gauge was appropriate for the long speaker run and a 300 watt control with a 150 watt amp.

Excellent build, Sturdy and easy to install.

I am now able to adjust the volume without going inside to my where my amp is at. Highly recommend these volume control.
Before painting I used #200 wet/dry sandpaper so the paint will adhere to box.
