MODEL- R275HC VENDOR- RUSSOUND

FEATURES- Audio Amplifier- Black
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.
* Selectable low-cut filter for the protection of autoformer-based volume
controls and speaker selectors.
* Bridgeable zones to create flexible power configurations.
* 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.

In 1967 in a quiet town in rustic New England, Russound was founded based on a desire to make the finest audio accessories on the market. The company’s early products included hi-fi solutions such as speaker selectors, tape monitor switchers and volume controls. The name Russound became synonymous for high-quality volume controls and the company soon developed a reputation as the industry’s leading manufacturer.
