Easy Install. Is as expected; have speaker zone and volume control to multiple zones in house.

This device was relatively easy to use. It provided the needed amperage to the four sets of speakers we used with room for 2 additional.

Running 5 zones in house off of an old Yamaha receiver. Set-up was tedious with screw-in wire connectors, but that allows you to change the sequence of the speaker terminals later without un-doing anything (just un-plug & re-plug blocks into the desired terminal).

Sound is solid, even with no amplifier on 6-yr old low-end receiver.

Drawbacks (2) are minor - first is the price which seems excessive even though the unit appears built to last. second is the lack of range on the volume selectors and the adjustability is limited to "clicks" instead of fine tuning.

Overall a solid piece of equipment that allows for easy push button zone selection.

Crutchfiled experience was excellent (as usual).

I installed 2 of Niles speaker selectors for my house. I have installed 12
pairs of speakers and needed to select among them and adjust the volume
appropriately. I have since installed 5 more speaker pairs, and just ordered
a 3rd of these Niles.

The product features a high quality construction. They are built like a tank.
The volume knobs are sturdy. No hiss, no noise, no cracking. I'm very
impressed. I think the ultimate test for a speaker selector is to turn on a
single pair, and start turning the others one at a time. Since the Niles
automatically adjusts the impendence as you add more speakers, you can't
even hear volume variations on the first pair you had on. That is a
testament to how smoothly it performs the transitions from 1 pair to all 6.
That smoothness is what your amp needs to be protected.

I personally like the screw-in terminal. When you are dealing with 18 pairs
of speaker, you need to be able to take your time and space screwing in
the wires and ensure there are no exposed wires. Then, the terminal plugs
in perfectly on the back on the Niles. At that point the space and visibility
can be limited, but you know it is plugged in correctly (the connectors are
keyed so that they can't go in backwards), and the wires are secured in
place.

I set up my Niles to have all the speaker volumes 2 positions below the
maximum. That allows room to increase the volume 2 notches in places I
want to be louder (by the pool, or garage), without sacrificing quality.

I found this product very easy to install. What do you expect hooking up 6 pairs of speakers and 1 set to the amp.

I have it distributed to 6 rooms on main floor including kitchen, dining, family, playroom, gameroom and office. I use in-wall Polk speakers. Its great to be able to set each individual room with a default starting sound level. Additionally any room can be turned off/on in any combination. I have a low-end Sony receiver as my sound source and it integrates nicely.

I found the music delivered via the Niles box was clear and covered a wide spectrum. Bass was lacking but I expected that with smaller in-wall speakers.

What is it lacking...No remote control capabilities at all on the unit but that can be suplemented by the receiver/amp that will be connected to it. Wire guage was difficult to get into adapters - switched down one grade and it was easy to insert and screw. No bass/treble controls.

I recommend this unit for anyone looking for simple speaker distribution with above average sound and ease of implementation. Its not going to set any artist on fire but delivers as expected.

The Niles SSVC-6 touts undistorted signal division for up to 6 pairs of speakers. Despite its rather tedious speaker-wire connection set-up, I decided to try it, based on the encouraging spec sheet. However, I was very disappointed by the flat, muted signal it actually transmitted. Even after reducing connections to one speaker pair, I was unable to get the SSVC-6 to produce a better signal. Increasing the volume (or signal feed) only made it louder, but still flat and two-dimensional. It was a relief to disconnect it and hear full, three-dimensional sound from my speakers once again. Especially for the price, this device is a big disappointment. Audiophiles beware.
