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-6HP is a robust, efficient dual-source speaker selector for up to six 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-6HP is designed for use with either 4- or 8-ohm speakers.
The PRO-6HP 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.
