    Speaker Volume Controller RMS 75W (Rotary Type) - White

    This is a rotary-type wall plate volume control for speaker systems with power ratings of up to 75 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 75 watts per channel.

    Please note: This volume control does not include a wall mounting bracket.

    Support Files:

    Input 2 channels, 75 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.

    Does this item come in an off-white color, like ivory or almond?
    New User U on May 4, 2017
    BEST ANSWER: the ones I have are white. If there is another colour it will have a different item #
    Hello..I installed a 100w in-wall volume control. It only has sound on the last 4 volume clicks of the dial. The rest are just silence. Did I buy one that was too powerful? Should I have purchased the 50w?
    A shopper on Nov 27, 2017
    BEST ANSWER: Do your speakers have transformers? If they are low z speakers then you need a low z VC not a 70V etc.

    PROS: Works fine...after a little fine running of the speaker wire

    Volume control
    I have used this one and I will continue to use them.

    PROS: Great unit- Priced better than most distributors.

    CONS: The depth..You cant use a box for this device. You have to use a trim out ring.

    volume control
    Wiring terminal slips right off for easier wiring installation. The internals are large, so you will need to be careful when putting the wires back in the box.

    Knob works smooth better the others I have purchased.

    Looks great on the wall and adjust the volume just as expected.

    PROS: Easy to install.
    Works great.
    Comes with cover plate.

    CONS: None

    Installed and working great
    Installed 3 of these when i was renovating our house, they all work great.
    As good if not better then name brand volume controls, for way less $$$.

    PROS: low cost, easy to install, good build quality

    CONS: none

    Did the trick!
    Used for adding control to in-wall speakers in extra rooms. Was not looking for audiophile listening, just for background music. This item worked perfectly...and the price was fantastic for the quality.

    PROS: Metal enclosure, does exactly what it is supposed to do.

    CONS: Wire terminals a little small.

    volume slider was broken
    Wish quality control could look at the parts before they are shipped. It's almost as if some of these items were returned once and someone snatched a part or two???

    PROS: ordered two and one was broken on the slider

    CONS: one was broken on the slide and had to return, only after returning the previous one that was also missing clips. A bit disappointing. The one that does work seems to work quite well.

    Works well but difficult to install
    The biggest problem with this device is that it is too big to fit into even an extra deep electrical box. I had to modify my boxes with a Dremel tool to get them to fit. I think maybe these need special boxes, but that wasn't made clear. And I wanted them in double boxes.

    Then, the connectors are not seated very positively and would become disconnected when inserting the unit in the box. So I had to wrap them with electrical tape to get them to stay, which added size making fitting even harder.

    Once in the wall, these work great! I have no loss of signal when running multiple speakers like I did with a simple a switch.

    Damaged Order

    CONS: Large single box order only had the volume controls damaged. We assumed the four volume controls were damaged prior to shipping since no other items were damaged.
