About the Niles SS-4

The Niles SS-4 lets you send music from a single amplifier or receiver to four pairs of speakers throughout your home.

Product Research
Features
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.

THIS THE SECOND NILES UNIT I HAVE BOUGHT. MY FIRST ONE STILL WORKS PERFECT AFTER 12 YEARS. I JUST NEEDED A THINNER UNIT TO FIT MY NEW SETUP. I AM SURE IT WILL PERFORM JUST AS GREAT.
