PRO-8 HP 8 Pair, Impedance Matching Speaker Selector

Designed for demanding applications, this high-quality speaker selector features a low-frequency protection circuit to reduce subsonic signals. This allows higher power operation without amplifier shutdown. An A/B switch on the front panel allows you to power all your speakers with either of two source amplifiers. The PRO-8HP is designed for use with either 4- or 8-ohm speakers. The PRO-8HP uses audiophile-grade autoformers for impedance matching to maintain a safe operating load at the amplifier while distributing maximum power throughout your system. A rotary switch on the rear panel sets the appropriate impedance for your amplifier, based on the number of speaker pairs connected.
