The SS-4 allows you to connect multiple pairs of speakersto your stereo receiver or amplifier and play any pair, any combination of pairs, or all pairs simultaneously. You don’t have to worry about overloading your amplifier. The SS-4 has a protection circuit that keeps your amplifier running safely, even if you have all pairs of speakers playing at the same time.

Balancing Speaker Volume
The volume control on your receiver or amplifier serves as the“master” volume for all speaker pairs connected. The volume level of the speakers may vary from room to room. This is caused by several factors. Two lesser factors are the size of the speaker and its efficiency. The largest factor is the physical size of the room. The best way to balance speaker volume is to equip each of the speaker pairs in your system with a Niles volume control. The controls allow you to adjust the volume of each peaker pair individually. If all the speaker pairs in your system are equipped with Niles volume controls, you can leave the amplifier or receiver volume set at one position nd use the Niles controls exclusively.
SS-4 Power Handling
The SS-4 is designed for use with a receiver or amplifier having a maximum power output of 100 watts per channel at 8 ohms. Damage caused by the use of a higher-power receiver or amplifier will void the warranty. Niles speaker selectors with higher power handling capabilities are available. Consult your Niles dealer, or receiver/amplifier manufacturer, if you are uncertain about the power rating of your receiver or amplifier.
Amplifier Impedance Load
As more pairs of speakers are parallel connected to a receiver or amplifier, the overall system impedance becomes lower. For example, if two pairs of 8-ohm speakers are connected in parallel, the impedance will be 4 ohms; two pairs of 4-ohm speakers in parallel become 2 ohms, and so on. Most receivers or amplifiers are not rated for use below a 4 ohm load. Most manufacturers do not recommend connecting more than two pairs of speakers without using some form of impedance correction.
The SS-4 includes impedance correction circuitry which protects your receiver or amplifier from low impedance loads. The circuitry assures that your receiver or amplifier will see a safe operating load,
