The Russound PRO-8 HP is a central speaker selector for systems that need to run 8 rooms of speakers from one location. A front-panel A/B switch chooses which of two source amplifiers feeds all connected speakers, while individual room switches turn each zone on or off.
Audiophile-grade autoformers handle impedance matching, and a rotary switch on the rear panel is set according to the number of speaker pairs in use, so the amplifier sees a safe load no matter how many rooms are active. The HP version adds a low-frequency protection circuit, a bipolar-capacitor 6 dB high-pass filter centred at 30 Hz, that trims subsonic energy so the system can be played louder without tripping amplifier protection. Power handling is rated at 100 watts RMS continuous and 300 watts peak per channel. Speaker wiring lands on detachable, colour-coded snap connectors that accept up to 14 AWG, and printed room labels are supplied for a finished look.
Key Features
- A/B dual-source input switching
- 8 speaker-pair zone switches
- Autoformer impedance protection with rotary setting
- 30 Hz low-frequency protection filter
- Detachable colour-coded connectors, printed room labels
Ideal Applications
Larger homes, offices, retail spaces, restaurants and fitness areas where one or two amplifiers must drive many rooms of in-ceiling or in-wall speakers with central on/off control.
Compatibility
Works with conventional stereo amplifiers and receivers and 4- or 8-ohm speakers; not for 70V systems. Room-level volume can be added with impedance-matching wall controls such as the ALT-126R. Set the rear SPEAKER PAIRS switch to the number of pairs connected when amplifier and speakers share the same impedance; use twice that number for an 8-ohm amplifier driving 4-ohm speakers, or half for a 4-ohm amplifier driving 8-ohm speakers. Any speaker pairs wired together must present at least 4 ohms. Russound covers speaker selectors with a 10-year limited warranty.
