Russound PRO-12HP Dual Source 12 Pair Speaker Selector

PRO-12HP Dual Source 12 Pair Speaker Selector The PRO-12HP is a highly efficient dual source, impedance-matching speaker selector. This high quality speaker selector is designed for use with either 4 or 8 ohm speakers. The A/B switch located on the front panel allows all your speakers to be driven from either of two amplifiers. The PRO-12HP speaker selector is equipped with a low-frequency protection circuit to reduce subsonic signals. This allows higher power operation without amplifier shut-down. Utilizing audio-grade impedance-matching autoformers, the PRO-12HP is capable of maintaining a safe operating load at the amplifier while distributing maximum power throughout your system. The PRO-12HP is equipped with a rotary switch, located on the rear panel, which is used to set the appropriate impedance to be seen by your amplifier, based on the number of pair of speakers connected. This switch selects the proper taps of the autoformers, allowing the amplifiers power to be delivered safely to the speakers.
