Saga Home Edition SAG5500HE 12-Zone Dual Source Stereo Speaker Selector, For use with both 4-ohm or 8-ohm amplifiers

This Dual Source Speaker Selector from our Saga Home Edition™ series is a highly efficient impedance-matching selector designed for use with both 4-ohm or 8-ohm amplifiers and 4-ohm to 8-ohm speakers. It’s equipped with a low-frequency protection circuit to reduce subsonic signals, which allows high power operation without amplifier shutdown. Autoformers are very efficient because of the small loss incurred as a result of heat dissipation. This makes it safe for you to incorporate up to 2 speakers in all twelve zones. There’s a back panel rotary switch, which is used to set the appropriate impedance based on the number of pairs of speakers connected. In addition, the "make before break" design protects your amplifier(s) from damage caused by potential dead-short circuits. Premium construction provides excellent reliability, precise switching and noise-free volume control.
