Crutchfield Customer Review (What's this?)

Behaves as expected.

Pros: speaker cable attachment system

Love it

Crutchfield Customer Review (What's this?)

it works what can I say. There is something "not elegant" about splitting up my power amps output between 4 sets of speakers. But that's the way my house is built and this unit couldn't do it any better. There is no change in sound quality running everything through the SSVC-4. It works perfect and balancing volumes in all the rooms is a breeze for me because of the layout of the house.

Crutchfield Customer Review (What's this?)

Fantastic product! Allows me to control 4 separate pairs of speakers and independently adjust on/off and volume level. Love having music throughout my whole first floor. (Front porch, kitchen, living room, and rear deck). you are hooking up to the "main speakers" of an existing home theater system, you will have to recalibrate or adjust the sound level, it will be lower than before. Price seems high, but as they say, you get what you pay for!

Pros: Well constructed

Cons: Terminal Blocks are small and challenging to work with 12 gauge speaker wire.

Exactly what I was looking for ... separate volume controls for 4 separate zones.

Works like a champ

Crutchfield Customer Review (What's this?)

Niles unit was recommended solution to attach outdoor speakers to a home theater unit
by the Crutchfield advisor. Extremely happy and glad I went ahead and got the 4
speaker unit... I can finally add a set to the kitchen which I would have done years ago
had I only known how easy it was. Almost wish I had gotten the SSVC-6 although I need
the extra capacity right now.
I really like wire connector/harness on the back. I am working in a tight space and it is
difficult to hold a light and get the wires through the connector clips on the amp. With the
removeable rail I was able to wireup each speaker/amp input where I could see and
then just slide in the rail and screw it tight at a 90 degree angle to the back of the unit...
nice engineering!

Perfect Solution

Crutchfield Customer Review (What's this?)

We bought a new property which is very open. It is a beautiful post modern glass house
where all the rooms flow into one another and into two outside areas, one a pool area
and one a side garden/orchard/BBQ area. We have five pair of speakers: pool, great
room, BBQ area, Master Bedroom and Guest Bedroom. Putting the two bedrooms on
one circuit with this speaker selector allows us to fill the property with music. Being able
to control the volume in each of the areas allows a blend of sound that is very balanced.
Without the individual speaker controls, we would have to have speaker controls in each
area. This allows us to balance the sound from the central source. This device can
handle the power, never blowing the amp. We used the Airport Express to connect our
iTUNES library to our amplifier so we can fill the house with great music for our many
parties. A perfect LOW COST solution which performs just as the Crutchfield advisor
said it would. I am going to buy the 6 pair NILES for my primary home in Northern CA.
Thank you Crutchfield! Easy set up and perfect performance!

Great Product

Crutchfield Customer Review (What's this?)

I love this product and it does exactly as advertised. It was very easy to hook up, great selection of labels, and the ability to independently control the volume for each set of speakers is very easy. I'm using this with speakers in the living room, master bedroom, and outside deck and each is set at different volume levels. I highly recommend this for those looking for a simple yet effective device to control Zone 2 speakers.

Crutchfield Customer Review (What's this?)

Great product, easy setup, though I balked a bit at the price. I love the wire connections. My dream of multi-room volume control is now a reality. Initially I wished the volume controls turned smoothly instead of in set increments, but after using it I find that I do like the incremental adjustment. Trust Niles -- and Crutchfield.

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.

Removable Speaker Terminals: There are four removable speaker output terminal blocks and one removable speaker input terminal block. The blocks are removable, making it easier to wire the SSVC-4 into your system, and the blocks accept 14 to 22 gauge wire.

Protection Circuitry: The left and right channel ground returns are isolated to make the unit compatible with all types of amplifiers. The impedance magnification switch on the rear of the unit offers settings for up to six pair of speakers (even though there are only four pair of outputs) so the impedance load presented to the amplifier remains constant.

Volume Controls: The volume controls use autoformers instead of L-pads to minimize power loss and heat production. Each volume control uses a 12 position rotary knob with "pop-free" switching and 54dB total attenuation.

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



  • Frequency Response: 20-20kHz +/-1.2 dB
  • Power Handling: 100 watts per channel RMS at 8 ohms
