Sound splitting

Written By Rich, Bellaire, Texas on Thursday, November 26, 2015

Crutchfield Customer Review (What's this?)

Excellent piece of equipment to slit sounds to different speakers. Easy to use and far better than the Realistic splitter I replaced. I would highly recommend it

Pros: Easy to set up. Directions very clear

Cons: The tabs are a little hard to pull up to insert wires

Niles SS - 4

Written By Robert, Orlando on Monday, July 27, 2015

Crutchfield Customer Review (What's this?)

Does just fine. My only wish would be that you can't shut off zones wirelessly.

Pros: fair price

Cons: not able to turn zones on/off wirelessly

Works as advertised

Crutchfield Customer Review (What's this?)

The magic box works just like it is supposed to. I do not understand the issue people have with the wire connectors. They are easy and quick to use. The buttons work well. The box is black like every other piece of hifi equipment. It is all just ducky.


Written By Doug, Maryland on Wednesday, October 29, 2014

Crutchfield Customer Review (What's this?)

It woks well. I used this to replace some switches I had installed to send the signal to speakers in different rooms, but this is better because it allows multiple speakers to play simultaneously. I am using it with the Onkyo 929 receiver driving all three zones.

Pros: simple to set up and use

Cons: none

niles ss-4

Written By Brett, Bloomsburg, pa on Monday, August 04, 2014

Crutchfield Customer Review (What's this?)

The niles ss-4 works like it should. I have it paired with the Yamaha rn-500 and it allows me to listen to music in any area of the house. My only gripe is the connectors on the back are a bit small and I had to trim the 14 gauge wire to make it fit. 16 gage would fit without any trimming.


Written By JerryO, Clayton, CA on Friday, May 30, 2014

Crutchfield Customer Review (What's this?)

great simple product; performed well after troubleshooting issue with the receiver shutting off after10 seconds of power; wire strippers are a "must" for this simple project

Pros: simple and easy to install

Cons: after installing speaker wires, receiver kept shutting off; checked and rechecked wiring with no success; sent Niles(mfr) very detailed email with receiver/speaker specs to see if the combination may be culprit; while waiting for a response, I researched on line possible solutions; a source suggested that too much speaker wire was left bare in the back of the ss4; purchased a wire stripper, restripped wires, and everything worked;never received a response from Niles;poor service on their part

Works as expected

Written By Alan S., Boulder, CO on Monday, May 26, 2014

Crutchfield Customer Review (What's this?)

Works as expected. Very easy to install. Switching 4 sets of speakers, no problems.

Pros: Easy install.

Could not have been easier!!!

Written By JK, Huntsville, AL on Wednesday, April 16, 2014

Crutchfield Customer Review (What's this?)

This was easier than I thought. Could not have been simpler to hook up or use. .

Pros: Easy Hook up, once I had micro srewdriver. Easy to use.

Cons: Pins are a little hard to get open for wire insertion, but micro screwdriver solved that issue.

Simple and Effective

Written By JulieT, Las Vegas, NV on Thursday, December 05, 2013

Crutchfield Customer Review (What's this?)

We needed a low cost solution to connect existing in-wall speakers in 4 rooms to our home theatre stereo. The Niles SS-4 was perfect fit. I'm no AV expert, but I was able to figure out how to get it hooked up and am now enjoying music throughout my entire home without having to by a multi-room amplifier.


Written By Anonymous, Hollywood, FL on Tuesday, February 19, 2013

Crutchfield Customer Review (What's this?)

Works as advertised. Paired with the Yamaha rxv673.

Pros: Push of a button to activate each room.

Cons: None

Positive ending

Written By PeterD, Buffalo, NY on Monday, February 04, 2013

A follow up to my earlier review: I contacted Niles about the switch problems I was having , and after returning the defective unit to them, i received a brand new SS-4. Great customer service!

Switches Fail

Written By PeterD, Buiffalo, NY on Wednesday, January 09, 2013

Crutchfield Customer Review (What's this?)

I have had this unit for about 16 months. Within six months after purchase two of the switches began to stick. It became necessary to pull them in and out instead of having them "snap" in and out. Within another few months, one of the switches began to short out, so it is now necessary to jiggle it to get both speakers to work.

Just what I needed

Written By Grayhouse13, Mulberry Florida. on Saturday, November 10, 2012

Crutchfield Customer Review (What's this?)

This is exactly what I was looking for, tried another from a local chain store, but it was cheap and it would loose a lot of sound, this one was perfect and I love it.thanks crutch field, this was my first order from them and it was perfect.

Pros: Well made and easy to use

Cons: None

Great product

Written By RobertM, Kansas City, MO on Sunday, June 19, 2011

Crutchfield Customer Review (What's this?)

This is a sleek well-designed product. The detachable connector plugs are also really helpful--allows you to make each speaker's connections easily in the comfort of your hands in good light, and then plug the whole little assembly into the speaker selector.

Protects my reciever but...

Written By Mike F., Otwell, IN on Friday, December 03, 2010

Crutchfield Customer Review (What's this?)

This box does what I want it to but it does have it's flaws. It doesnt give you much room
to work on the back as far as hooking the speaker wire, 14 gauge is about the biggest it
will accept which is mostly all that any guy needs but if you wanted to have bigger wire it
won't fit. The thing I dislike the most about it, I have a 100 watt high-current receiver and
want to power my Advent Legacy 2's. My speakers are 6ohms, so if I run the speakers
without the Niles box it's drops my receiver to an unsafe 3ohm load. I purchased this box
to protect the receiver. When I run all 4 speakers it cuts my sound down, my sound is
better just running 2 speakers without the box. If you want to purchase this box for
speakers in separate rooms this would be perfect. I'm a stickler for perfection when it
comes to sound but also can't afford Mono Blocks.haha If you are running into a
situation as I have had on an unsafe load, I wouldnt purchase this, it's not worth the
money to have 2 extra speakers sound like they are in a concrete building.

Does what it's supposed to

Written By Anonymous, Houston, TX on Friday, July 23, 2010

Crutchfield Customer Review (What's this?)

Not much to say really. I set up 8 in-wall speakers in 4 pre-wired rooms and power them all through this box from the extra set of outputs from my receiver. Works great! Does what it's supposed to do, and the speakers sound great.

Niles SS-4

Written By Curtis, Portage, MI on Friday, July 17, 2009

Crutchfield Customer Review (What's this?)

Love this little guy! I have all 4 sets of speakers hooked up and they all sound great! The speakers sound great no matter how many I turn on. I would recommend this to anyone. Please realize that if you have an amp that has an A and B front speaker set, you can not run the B set off of your amp they must go through the Niles unit so pay attention to how many speakers sets you need in total.

could they make the connectors any smaller?

Written By Bear, boston, ma on Wednesday, June 10, 2009

Crutchfield Customer Review (What's this?)

1st off I got an ALMOST DOA unit. hook up 1 set of speakers, it works. hook up 2nd... problems, volume dropped, amp shut down, etc. I tore all the wiring apart 3 times, thinking I made a mistake. Every time, it's flipping those little connectors. Then checking connectors, and hooking them into the amp, and it works. make it a little bigger, and give it a real connector. I e-mailied Niles this past week and received no reply. I will try calling them in the morning. Either that, or I'll just add a 2nd power amp to dirve the 3rd set of speakers (not hooked up... couldn't get 2 to work right thru the unit). Most people seem to love it, so, I didn't give it a 1 star, but, I couldn't give it any more than 2.

Crutchfield Customer Review (What's this?)

I've had the Niles ss-4 for about a month and it works great. With my amp at about 1/4 volume I get plenty of power to three rooms. Haven't installed fourth set of speakers yet, but don't anticipate any problems.

Great Device

Written By Baiju, Anaheim, CA on Tuesday, December 30, 2008

This device works great. It was recommended by the Cruchfield staff. I use it with eight speakers and the sound is great if I have two on or eight. Highly recommended for multiroom setups.

Don't Gamble your Receiver

Written By Scott, University Place, WA on Monday, October 06, 2008

Crutchfield Customer Review (What's this?)

If you want multiple speakers around your house...or even outside on the deck, etc... this is really going to tax your receiver. Advice- add up the load...the total ohms and see what your receiver can handle... then get a top rated speaker switch with a protector built in. The protector in most recievers will function well for a while...but keep pushing it..and it will fail. Double the back up. The speaker switch I had before is in the garbage. Get the Niles and give your reciever a break!

Product Research



Construction: The chassis is durable black metal with padded feet.

Speaker Switches: Each set of speaker outputs has an on/off switch so any combination of connected speakers can be played at any given time.

Protection Switch: The impedance protection switch on the front of the unit safeguards the receiver or amplifier even when all 4 pairs of speakers playing (4 pairs of 8-ohm speakers will present a 4.5-ohm load to the receiver or amplifier).

Note: You will need to activate the "Protection" switch whenever the overall system impedance might fall below 4 ohms. It is recommended to verify that the receiver or amplifier is capable of driving a 4-ohm load.

Removable Speaker Terminals: There are four removable speaker output terminal blocks and one removable speaker input terminal block, each of which can accept 14 to 22-gauge wire (16-gauge recommended). This makes it easier to wire the speaker selector into your system.

Labels: Included are 72 pre-printed and 6 blank label stickers for easy identification of the front panel controls.



  • Frequency Response: 20Hz-20kHz +0dB,-0dB (flat)
  • Power Handling: 100 watts per channel RMS at 8 ohms
