    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.

    Support Files:

    Input 2 channels, 100 watts per channel
    Output 2 channels, 4 to 16 ohms impedance matching
    Frequency Response 35 Hz to 20 kHz (+0/-2 db) at rated power
    Wire gauge 14 to 16 AWG
    Material Plastic ABS
    Depth 2 3/4"

    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.

    Very Well Made at Great Price

    Pros: Easy install
    Great quality build

    Cons: Can be a tight fit for some openings

    A very well made volume controller. The weight alone gave me confidence! Installed without any problem and works as advertised. My audio-video guy helped me with installation and he even commented on the quality. He installs very high end systems and was unfamiliar with Monoprice. Think I might have converted him.

    Great volume control

    • Kaden,

    Pros: High power
    Easy to Install

    Cons: Matte white
    A little large
    "Clicks" when turned

    This is a great volme control. As others have mentioned it is more of a matte white color. It is also a bit on the large side, but I was able to install it in a low voltage box just fine. It accepted my 14 AWG wire just fine unlike some others. One thing that I don't like is that when you turn it it "clicks" into each posistion. Overall it is a great volume controller for the price.

    Works well, just watch the colour and finish

    • Anonymous,

    Pros: Good quality
    solid piece of hardware
    easy to connect to
    works as advertised

    Cons: finish is not bright white
    finish is also very matte vs. as compared to most switches/outlets

    Works as advertised - just note that the colour is slightly off-white and not bright white / higher gloss white like most current decora switches and outlets. Side by side you will notice a difference in finish.

    Cost Effective and works well

    • jagnag,
    •  Calgary, AB 
    • 12/14/2015 8:07:11 AM

    Pros: + good price
    + work well
    + good volume
    + rotary "bumps" let you set the volume in multiple steps
    + configurable by jumper for different setups (see impedance correction chart in product description for details - I saved a copy for future reference)
    + good price compared other other sites

    Cons: - Note the size: they are large units and would have struggled to put these in a single gang electrical box. Luckily my wiring guy used low voltage plates during the construction of our home which made it easier. Even then, the plate's hole was just barely wide enough to accept the volume control unit. Had to slide in at an angle which was tricky because the wires kept trying to push the unit's jumper pins into the plate and actually bent a few pins before it got inserted properly.
    - Jumper pins are in a terrible location and will catch and bend while inserting or removing the unit into a low voltage wiring plate.
    - Rotary knob seems smooth on 3 of the units but the 4th one is a little tight around the 4th or 5th stop. Hopefully it doesn't seize up like others have reported happening.

    Received quickly but shipping was almost 50% of the total cost. They work as expected and are a good deal for the price (paid $17.87 + shipping). I ordered 4 and all worked OK. Would order again if needed.

    Size Does Matter - This One fits well in Single Gang wall bracket

    • Satisfied&Happy ,
    •  Raleigh, NC 
    • 7/14/2015 6:40:59 AM

    Pros: Fits into single gang - tight squeeze though
    Simple look - easy on eyes

    None - For Reviews that says it is too big and does not fit - Well they should have read the specs right on this page that says (depth - 2-3/4"). So the size of the unit is not a Con at all.

    I received it yesterday and the unit was in the wall within 20 minutes. Sound quality is good and I didn't notice any loss at low freq. at any volume range. IMHO, sound quality is quite rich (but then again this is personla perspective and not a standard). It Will take a little bit time to see long term durability. So I am all happy about this product.
    My review is mainly in response to people who says that this is too big and does not fit into a single gang - Really ??? Did you not read the specs. of the product right on this page before you ordered? That simply means you did not do your homework right.
    By the way it does fit in the single gang albeit a tight squeeze. The way connectin posts are located on the unit(top and bottom) all 8 wires will fit in the box. You need to run 4 from top (to speakers) and 4 from bottom (from the source). Once in the gang, there is no room for wires on the side but top and bottom have enough clearance - you need to spread wires a little bit. I would suggest that sometime we need to improvize and customize instead of whining and complaining. In my case, no I didn't need to improvize however, if I had to, I would be posting the update on how to do that. Anyway, Thanks Monoprice for another good product.
