Speaker Volume Controller RMS 50W (Slide Type) - White
This is a slider-type wall plate volume control for speaker systems with power ratings of up to 50 watts per channel and impedance ratings of 4 to 16 ohms. This slider control can be set to one of twelve positions, including the minimum (off) and maximum volume settings.
The wall plate mounts into a standard single-gang, low-voltage wall bracket (not included) and has inputs and outputs for one pair of stereo speaker wires (4 input connections and 4 output connections). It can accept speaker wire in sizes from 14 to 16 gauge and provides a frequency response range of 35 Hz to 20 kHz (+0/-2db) at the full power rating of 50 watts per channel.
Please note: This volume control does not include a wall mounting bracket.

When setting up the speaker volume controls, it is important to match the impedance of your speaker system with the load rating of your amplifier. This is done by setting the jumpers on the volume control to compensate for the number of speakers you have in a parallel configuration and the impedance level of the speakers.
If using a single pair of speakers rated at the same load level as your amplifier, you don't need to make any changes - just leave the jumper in the default x1 position. However, if your speakers are of a different impedance level and/or you have more than one set of speakers in parallel, please refer to the following chart as a guide for setting the jumpers on the speaker volume control.
Note that for any speakers wired in series, the overal impedance level is the sum of each speaker. So two 4 ohm speakers wired in series is the same impedance as a single 8 ohm speaker.

PROS: well made, sturdy and a great price
CONS: plugs tend to slip off the connectors easily when putting back into the opening, check your volume before screwing back into the wall, or maybe a drop of superglue to keep plug firmly attached once wires have been inserted.
PROS: Looks good.
CONS: A little stiff in the overall action.
I ordered most of my equipment from Monoprice. Specifically, I ordered this volume control switch to control the volume of 4 ceiling mounted JBL speakers that provide audio to our new great room. I wanted a very modern look with all my switch-plates and accessories...and this volume slide control is already the envy of most of my friends after seeing our "new" home.
This is no toy... this is the real deal..with very substantial guts behind that slide control. It was a snap to install. granted...I was working with walls gutted down to the studs...like new construction...but this device could fit into any existing home if you know how to fish speaker wire down the wall and install a single gang box. (or hire someone to do it)
This Speaker Volume Controller literally changes the dynamics of everything...the feel of the slide is all-pro..nothing flimsy or "discount store" about it..ie: no popping, static sounds while adjusting volumes, and finally, it gives your media room, dining room, den or living room that all-pro installation look...and the sound quality.
As I said earlierm, th hyper-white switch-plate cover also matches all the other items I purchased here at Monoprice for my wall mounted TVs... I could not be happier...and thank to my pal Nolan for turning me onto Monoprice!!
PROS: Looks fantastic, rediculously easy installation, well built, substantial, very fair price, hyper-white to match all my other switch plate covers, slide action works like a charm!!
CONS: none, zero, nada.
PROS: Excellent product in every way.
CONS: cheaply made
