10 Reviews | 3 questions - 7 answers


The Niles ABA-1D in-wall "A-B" selector comes in handy for two different types of custom audio installations. Use it to safely switch between two different powered audio systems you connect to one pair of in-wall speakers. Or, send music from a single audio system to one of two pairs of connected speakers. Hum along to your favorite music in the kitchen while you cook, then switch to your patio speakers while you enjoy an outdoor meal.

I am using this unit to switch a set of speakers in a den between either a small amplifier in the room for a source different than the rest of the house or to tie the den speakers into the whole-house system. Installation was a breeze and the switch is meeting my needs completely.

Pros: Quality unit, well priced, and easy to install


Good quality

Crutchfield Customer Review (What's this?)

I work with building automation and controls, and this seems to be a high quality item. Looked around and found some much cheeper, but none offered a ten year warrenty. I installed it outside to be able to isolate different receivers to one pair of speakers, and it works well. Only had it a couple of weeks, but don't expect any problems. If any arise, I can rely on Crutchfield to have my back!

Pros: Fits in a single gang box and installed a weatherproof cover over it.

Cons: It's a little deep, and it isn't cheep.

Can't beat Niles quality. This is the second Niles ABA-1D switch that I've installed. Does a perfect job of switching between two sets of speakers.

Pros: Installs easily, with simple connections.

Cons: None

Source selector switch

GeneS from NJ on 2/18/2014

Crutchfield Customer Review (What's this?)

Works great to select between two sources, one in the room with the speakers and the main one in the liv. rm. I used wire ferrels on the wires and inserted them into the connection terminals.


Cons: none

Crutchfield Customer Review (What's this?)

The speaker switch was easy to install but I needed to use a a low-voltage wall plate to avoid an electrical box, since this was installed in an old wall in my kitchen. A well made switch with screws to tighten down on the wires.

Pros: attractive wall switch; wire connectors seem superior quality.

Cons: somewhat expensive

Crutchfield Customer Review (What's this?)

Great product. I have 3 of them in use and have had no problems with them at all. My use for them is different than then intended function but works perfectly for what I needed. I use them as an On/Off switch for the speakers in remote locations in the house. I can turn the stereo on and control my music by WiFi through my iPhone. By pressing the button on this wall switch I am able to have music in the garage or the other side of the house without going to the remotely located speaker selector. Another bonus is I don't have to worry about a pair of speakers blasting music that I don't know are on since I can simply turn the switch off when I leave the space and stop the flow of music.



Highly recommend

Crutchfield Customer Review (What's this?)

Great product very easy to use. It's self explanatory and works great. Used it to go from two sources to two zones of speakers(basically a pair, as it says in the description). Plenty of room inside the receptical box for your wiring. Just make sure you have a small enough flathead screwdriver to tighten the screws down on the speaker wire. And it doesn't seem to take any sound quality/clarity away. Buy it!



Great Solution

JimmyG from STL on 8/5/2013

Crutchfield Customer Review (What's this?)

Perfect fix for my needs. I wanted to use 1 set of speakers as both rear surrounds for a home theater setup and as an additional set of speakers for when I'm running music throughout the house from another amp. This worked perfectly.

Pros: Easy setup, attractive, screw down terminals.

Cons: None.

Crutchfield asked  
Why did you buy this?

It did exactly what I needed it to do [ Joseph  Feb 02, 2017 ]

3 questions already asked

I know it can handle 350 watts per channel not I don't believe it is rated for a volt application but if you mean your speakers are 70 Watts it can more than handle it Enter [ Gerald  Apr 21, 2017 ]
I think it is. You could probably find something on line that would work, depending what is in the other half of the box. I have put a dimming light switch, with a center that same size, in a 4 gang box , with 3 other regular light switches and found a cover for that. [ Chris  Jun 03, 2016 ]
Yes. [ Rsvlrog  Jun 02, 2016 ]
Yes it's a decor plate which is the newer style switch plate. You need a duplex plate for the 2 gang depending what second item is. Make sure you don't combine 110 with low voltage in one box without the separator in middle. Any electrical supply should know what you need?? Good luck [ LOUIS  Jun 01, 2016 ]
Yes. [ Kevin  Jun 01, 2016 ]
I can't see any reason that would not work. Mine receives volume controlled directly from my receiver and works great. [ Greg  Dec 07, 2015 ]
I would think so. All this is, is a switching relay. Normally open or closed contacts. [ Chris  Dec 06, 2015 ]
