R275HC
Amplifier
The R275HC is a 2-channel high-current power amplifier capable of driving low-impedance loads. It incorporates a selectable low-cut filter designed to protect autoformer-based volume controls and speaker selectors.
This amplifier can be used for power upgrades in specific zones, for large speaker selector or volume control systems and for long series-parallel speaker runs (e.g., large outdoor zones).
The R275HC is rated at 75 watts per channel into 8 ohms and 100 watts per channel into 4 ohms. In bridged mono mode the R275HC is rated at 200 watts of power into a single 8-ohm load. All this power is supplied by a high-output toroidal transformer. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
Features Include:
- Selectable low-cut filter for the protection of autoformer-based volume controls and speaker selectors
- Bridgeable to create one channel with substantial power output
- High-performance design for demanding indoor and outdoor zones
- Reliable and robust circuitry designed for stability under demanding loads
- Convenient source loop outputs for easy connection to other components
