4. System Setup
The impedance at the amplifier or receiver will change as the number of speakers are
switched on and off. As more speakers are switched on, the total parallel system
impedance will be lower. The total impedance needs to be the same as or greater
than the minimum impedance drive of the amplifier. The system impedance of the SS-
4 with 4 pairs of 8 ohm speakers is 5.0 ohms. The system impedance of the SS-6
with 6 pairs of 8 ohm speakers is 4.33 ohms. In either system, a 4 ohm amplifier or
receiver will be required. When the SS-4 or SS-6 is used with an 8 ohm amplifier or
reciever, only 2 pair of 8 ohm speakers can be selected at a time. More than two
would result in an impedance that would be too low for the 8 ohm driving amplifier.
The recommended power of the audio amplifier should be no more than 100 watts
RMS per channel. If the SS-4 or the SS-6 is over-driven then damage will occur. The
maximum power handling of the SS-6 is 70 watts RMS per channel and the maxi-
mum power handling of the SS-4 is 100 watts RMS. If your power requirements
exceed that of the SS-4 or the SS-6 Russound offers many other impedance matching
selectors that will handle more power such as the PRO series.
The SS-4 / SS-6 outputs can be wired to the speakers directly or they can be wired to
an in-wall volume control so that the volume level in each room can be indepen-
dently adjusted without changing the volume level in the other rooms.
When the SS-4 or the SS-6 is used in conjunction with Russound volume controls,
the amplifier should be used as a master volume setting and the room-to-room vol-
ume changes are made at each volume control. When varying the volume level of
the amplifier, be careful not to turn the amplifier up to a level that the amplifier is clip-
ping or distorting.
The recommended volume control for this unit are the Russound Series ALT, LPT, XLT
or xALT. Consult your Russound dealer for details.

7. Warranty
The Russound SS-4 and SS-6 are fully guaranteed for Ten (10) years from the date of
purchase against all defects in materials and workmanship. During this period,
Russound will replace any defective parts and correct any defect in workmanship
