Product Research


Overview: The Russound PRO series speaker selector (PRO-12HP) 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, the PRO 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 Twelve Speaker Selector: The PRO-12HP is a robust, efficient dual-source speaker selector for up to Twelve 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-12HP is designed for use with amplifiers up to 100 Watts per channel RMS continuous and 300 watts per channel peak. The PRO-12HP is also designed for use with either 4- or 8-ohm speakers.

Note: Only one of the two amplifiers connected to the PRO-12HP can be active; they cannot be both on simultaneously.

Audiophile-Grade Autoformers: 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.

Impedance Switch: A rotary switch on the rear panel sets the appropriate impedance for your amplifier, based on the number of speaker pairs connected.

Speaker Selection: The PRO-12HP features twelve buttons on the front panel that allows you to select which speakers are playing (1-12) 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-12HP.

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-12HP provides four pair of speaker inputs for connecting two amplifiers and twenty-four pair of speaker outputs for up to twelve 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.

What/which input on the Receiver/Amp end should be used to connect the speaker selector to the receiver/AMP and type of cable/wire terminals that are ideal please? Thanks in advance.

A speaker selector would be connect to the speaker outputs of a receiver/amplifier, not an input. If multiple speaker outputs are available on your amplifier, then choosing which to connect to will depend on the nature of your amplifier/receiver and the goal of your project. This unit is designed to accept bare wire connections. For further help with your project, please reach out to our advisors via online chat or phone at 1-800-324-9695.

Is this amplifier compatible with the Sonos API so that I can control it through the Sonos app?

The Russound PRO-12HP is not an amplifier. It only connects multiple speaker pairs to a single amp (for instance if you want to distribute sound from one amplifier to multiple rooms). It is strictly controlled by the buttons and dials on the selector itself; no other apps.
albert  Jan 03, 2022
I will be hooking up 24 speakers that are identical name brand & power rating. Want to make sure I am providing enough power to drive the speakers. Can I hook up 2 power amps at once to the selector & divide the power? I.e- 12 speakers powered by each amp & all running through selector & all playing at same time?

The amp selector is either/or, you cannot do both or spread the power. The unit does accommodate12 pairs of speakers. there is a dial that needs to be adjusted correctly for the impedance. If your amp is 8 ohm and speakers 4, you may want to call an expert and make sure it can handle that adjustment for the full 12 pairs.
