Overview: The Russound PRO series speaker selector (PRO-6HP)
is a high efficient
dual-source impedance-matching selector. This high-quality speaker selector is
designed for use with either 4-ohm or 8-ohm amplifiers and 4-ohm or 8-ohm
speakers. The PRO series speaker selector is equipped with a low-frequency
protection circuit to reduce subsonic signals which allows high power operation without
amplifier shutdown. The PRO series unit also employs audiophile-grade impedance matching
autoformers to maintain a safe operating load at the amplifier while
distributing maximum power through the system. Autoformers are very efficient
because of the small loss incurred as a result of heat dissipation. In addition,
series selector is equipped with a black panel rotary switch , which is used to set the
appropriate impedance based on the number of pairs of speakers connected. This
switch selects the proper taps of the autoformers, allowing all the amplifier's
power to be delivered to your speakers. The PRO series speaker selector can be
connected to one or two amplifiers. A front panel button allows switching
between the two amplifiers for all speakers connected to the unit.
Note: The Russound PRO series dual source speaker selectors are
available in 6-channel, 8-channel and 12-channel.
Dual Source Six Speaker Selector: 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.
Two Amplifier Connection: 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 amplifiers up to 100 Watts per channel RMS continuous and
300 watts per channel peak. The PRO-6HP is also designed for use with either 4-
or 8-ohm speakers.
Note: Only one of the two amplifiers connected to the PRO-6HP can
be activate; they cannot be both on simultaneously.
Audiophile-Grade Autoformers: 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.
Impedance Switch: A rotary switch on the rear panel sets the
appropriate impedance for your amplifier, based on the number of speaker pairs
Speaker Selection: The PRO-6HP features six buttons on the front panel
that allows you to select which speakers are playing (1-6) so you can control
speakers in several rooms of your home from one central location. Printed room labels are
included so you can label the front-panel of your PRO-6HP.
Connections: The PRO series speaker selector has removable modular snap connectors
that provide color-coded wire terminations without the need for set-screws. The
PRO-6HP provides four pair of speaker inputs for connecting two amplifiers and
twelve pair of speaker outputs for up to six pair of speakers. Speaker
connections can support multiple speaker pairs wired in parallel or series,
provided their combined impedance is a minimum of 4-ohms. The unit's speaker
connectors will accept up to 14 gauge wire.
Optional External Volume Controls: If external volume controls (sold
separately) are used, connect speaker wire from the appropriate speaker
connector on the PRO series selector to the volume control input and from the
volume control output to your speaker.
