Great way to spread sound

Written by: Wayne from Massachusetts on December 22, 2015

Crutchfield Customer Review (What's this?)

The product was easy to use and easy to set up. The online information helped me to understand which switch I needed based on the speakers I'd purchased. I didn't want to spend a lot and have individual volume controls in each speaker location, so this switch was perfect for letting me have speakers in multiple rooms, but without having to worry about speaker conflicts.

Pros: Price, ease of use, simple set up

Cons: Doesn't allow volume control of each room separately, but I knew that upfront and was my decision based on price.

Created three zones

Crutchfield Customer Review (What's this?)

I was looking for a simple clean looking device to push audio to my garage and patio from receiver located in living room. Found what I was looking for at Crutchfield along with details on switch operation and how it functions. It is easy to install and functions exactly like it should. It allows you to choose all four zones or allows you to single in on a specific area to push music to. The built in protection is a plus as well!!

Pros: Clean appearance, Easy to set up, Functions exactly as advertised, Price for it's purpose.

Cons: Russound push in terminals are close in tolerance in back. I used 14 Gauge wire in the push in terminals and it was tight.

Easy to setup

Works Well



it works

Written by: BJ from Saratoga Springs on December 22, 2014

Crutchfield Customer Review (What's this?)

It fits my need perfectly. Connected speakers in four rooms to the unit and connected it to my receiver and now have sound in all rooms. I was worried I might have problem getting enough volume in all the speakers, but I could not tell the difference between connecting them directly and through the unit.



Russound SS-4.2 Review

Crutchfield Customer Review (What's this?)

I combined this with the Onkyo TX-NR727. Works as advertized!


Cons: None


Written by: TPC from New York, NY on January 14, 2014

Crutchfield Customer Review (What's this?)

This unit is a MUST HAVE for driving a combination of multiple sets of speakers (in this case, four sets, a total of eight speakers) with differing impedances. The unit is attractive, easy to set up and use.....the labels for each switch are a nice added bonus.

Pros: Easy set up.

Cons: No remote controller is would be a major plus.

Product Research


Overview: The Russound SS-4.2 Speaker Selector allows you to switch up to four speaker pairs connected to a stereo amplifier. Each pair of speakers can be turned on or off through individual front panel switches. It provides switchable built-in impedance matching, or can be used with impedance matching volume control. The SS-4.2 is designed for use with 8-ohm loudspeakers.

Impedance Matching Protection: When used with multiple speaker pairs, the impedance matching circuitry lets you operate the system safely with automatic overload protection. When connecting more than one pair of 8 ohm speakers to the speaker selector, the rear panel impedance switch should be placed in the "In" position. If using impedance matching volume controls (such as ALTx-2 or LPTx-2), the switch should be in the "Bypass" position.

Amplifier Requirements: When using internal impedance matching (switch set to "In") a 4-ohm stable amplifier is required. When using external impedance matching volume controls (switch set to "Bypass"), a 4 to 8 ohm stable amplifier may be used. You should use only the Amplifier "A" speaker outputs when the SS-4.2 is used. "B" speaker outputs should not be used.

Connections: The SS-4.2 features spring clip speaker terminals that can accommodate up to 12-gauge wire. For most applications, stranded 16-gauge speaker wire is recommended. For runs of over 100 feet, 14-gauge is recommended, while 12-gauge can be used for runs of up to 200 feet.

Performance: The speaker selector is designed for use with amplifiers with a power output of up to 100 watts per channel RMS (200 watts per channel peak. The frequency response is 20Hz to 20kHz (+/- 0dB).

Room Labels: The SS-4.2 comes with a sheet of non-adhesive room labels which slide into a groove in the front panel. A total of 52 labels and 8 blanks are included.
