Russound SS-6.2 6 Pair Single Source Impedance matching Speaker Selector.

SS-6.2 - 6-Pair Speaker Selector The Russound SS-6.2 Speaker Selector allows you to switch up to six 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-6.2 is designed for use with 8-ohm loudspeakers. Features 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. 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 am
