    Outdoor Speaker Volume Controller RMS 100W - Gray

    You're out in your yard enjoying your pool or BBQ. You've set up your outdoor sound system so that you can listen to music while you relax. What a hassle it is to go all the way back inside your house just to adjust the volume. Wouldn't it be easier to have a volume controller out in your patio?

    Here's your solution: an outdoor speaker volume controller. This specially designed unit comes in a weatherproof, sealed enclosure specifically designed for ootdoor installations. A simple rotary design allows you to set your audio to the perfect listening level.

    The water resistant enclosure also makes it perfect for marine (boating) applications.

    This rotary control can be set to one of twelve positions, including the minimum (off) and maximum volume settings.

    Support Files:

    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 overall 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.

    Overall a great design and does exactly what I wanted them to. The box is small and tight but I don't think I would be happy with a larger box mounted on my wall. Great deal and does the job well.

    PROS: Solid Design, Easy to Install, Looks good mounted on my patio.

    CONS: I have 6 Yamaha outdoor speakers and 2 of them are being controlled with this box on my patio. The unit does exactly what it is supposed to but the sound from these 2 speakers even at full volume is a little lower than the other 4 that are directly connected to the receiver.

    Great choice, easy to wire with good instructions.

    PROS: Arrived in short time. Works great.

    CONS: Small wire connections, but that is needed for the size of the unit.

    Outstanding deal
    If your on the fence about the quality of this volume control don't be. Just buy it.

    PROS: Well built, includes all the gaskets, speaker terminals come off for easy installation. Can't get over how inexpensive it is.

    CONS: None

    Works Great! Easy to install. Watch video online firts

    PROS: Works as advertised, very easy to install. The online video has all the info you need.

    CONS: One volume controller they sent me was defective, I called Monoprice and they shipped me out another one right away and that one works perfect.

    The connectors are very hard to access, and even harder to screw down, with the outer case in the way. 14 AWG wires barely fit in the connectors, and fit very poorly in the case. It took several attempts to get a tight enough fit in the connectors that the wire would hold and not pop out while jamming the cover closed on the case. You cannot use a regular screw bit to tighten the case as the hole is too small - you need to use an eyeglass screwdriver or something similar.

    I did not have these problems with the indoor volume control.

    Product no longer working
    This product did work for 2 years, but now no longer works properly. It isnt like the volume control is fully exposed to elements either since it is in my porch. Essentially one speaker is working fine but the other one isnt coming out properly. Having removed all the wires and reconnected them without the volume control, i can see the volume control is the problem. I have tried to fix the potentiometer with some fader lube but didnt work either. Now I have to buy another one since this one is likely out of warranty...but cant say I would want to replace it with the same one anyway. I dont recommend this product.

    Very tight fit
    I had the same problems as other reviewers due to the size of the controller and the box it is mounted in, i.e., it's difficult to get the wires in there with the controller. I understood these limitations when I bought the product, so I'm not surprised. I am using 12 AWG wires since I have an outdoor application with long runs to a pool area. I didn't have problems getting the wires into the screw mounts-they are removable and were big enough to accept the 12 AWG wires (barely). However, with the controller mounted in the box and the top wires running along-side it to exit the bottom, it puts a lot of stress on the controller so that the knob doesn't turn smoothly. I worry that this will not work well long-term. The box really needs to be larger, even for smaller wires.

    PROS: low cost
    impedance matching

    CONS: box too small for high quality wires

    Really tight fit
    I still don't know how this control works because I haven't been able to get it closed. Because of the length of my wire run, I needed to use 12 awg wire and it doesn't fit. Even with 14 awg, it would be a challenge to get this thing closed. The connectors are pluggable (thank goodness) but inconveniently located and really crammed in there. The unit itself takes up so much room that there is no room for the wire, even if I'd used 14 or 16 awg. Any outdoor installation is likely to have long wire runs and require larger wire – the manufacturer should have known this. I'm trying to find another conduit box to put it all in.

    PROS: price, pluggable connectors, seems well built

    CONS: Enclosure is too small and the connectors are inconveniently located. Wouldn't work unless you used really small wires which would require the amp to be very near - most likely outdoors and make this control unnecessary.
