Russound PRO-12HP - Dual Source Twelve Pair Impedance Matching Speaker Selector

In stock

The most important and most forgotten about subject in getting reliable and high quality distributed audio is arguably impedance matching...Forget these fundamentals and you will open up a host of issues!

The PRO-12HP is a robust, efficient dual-source speaker selector for up to eight pairs of speakers. 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-12HP is designed for use with either 4 or 8-ohm speakers.

The PRO-12HP 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.
