Speaker Volume Controller RMS 100W (Rotary Type) - White
This is a rotary-type wall plate volume control for speaker systems with power ratings of up to 100 watts per channel and impedance ratings of 4 to 16 ohms. This rotary 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 100 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.

Questions and Answers
PROS: cheap price
CONS: doesn't work as advertised
recommend these for a customer installation. Although the price is inexpensive the call back possibility will quickly erode any savings. Very cheaply made, but good sound quality and adequate for light duty use. We will have to see the long term reliability. Very pleased with Monoprice customer service.
PROS: Inexpensive volume control, great sound quality,
CONS: Cheaply made, sloppy feel. Need deep single gang box or better yet open back low voltage box. Ordered two one didn't work properly, but Monoprice shipped me another one without having to return the original. Work well for price and sound is terrific, Would not use these for a customer installation, too many quality control issues. Get what you pay for.
PROS: Nice design. Perfectly match my existing Decora light switch plates. Little to zero loss in sound quality and volume. Knob has discreet settings and I like the subtle "click" sounds as the knob is rotated.
CONS: After very little use, for reasons unknown, turning the knob felt like gum was stuck inside. The nice clicking sound disappeared, the knob was a chore to turn, and it felt rubbery, which rendered this volume control to be completely unacceptable. I purchased seven of these, but have only used one, so far, as part of a test setup before installing the rest of them throughout my house. It may be that this defect may be isolated to the one VC that I chose to use, but I'm not taking a chance and will return the rest for a refund.
If you need a great volume controller, spend the little bit of extra money and buy this 100W model. You won't regret it.
PROS: Device is built better than the 50W and 75W models.
CONS: Much larger transformers than the smaller models means that you have to modify your gang box. I'm using a steel case gang box with "battleships" for retainers, and I had to take off the side panel of the box to fit this unit into the wall.
going to need to have the defective unit replace. I wasted several hours troubleshooting this - in the end, it was just a defective unit... A little frustrated. I understand this sort of thing happens - but reading the reviews, it seems that it's a little too regular for this to happen. This is a poorly manufactured/tested product.
PROS: Works well.
CONS: Requires very deep outlet box, not standard box

The Decora Face and knob on this are NOT WHITE. When i put the white plate cover on, it's VERY off-white.
PROS: Works greatrotary knob is BIG
CONS: unit is very big won't fit in all elec. boxes.
