The Russound R1250MC is a 12-channel power amplifier ideal for use as the main amplifier in home theater and distributed audio systems. The 12 channels are arranged in pairs to provide amplification for six stereo zones. The R1250MC provides an array of useful features such as autosensing line inputs, bridged mono operation, independent zone triggering, bus inputs and multiple speaker outputs per zone to meet a wide variety of applications and configurations. The R1250MC is rated at 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms. With a zone’s mode switch set in the Bridge Mono position, both channels in the zone are combined for a mono output of 140 watts into an 8-ohm load. All this power is supplied by three high-output toroidal transformers. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme
The Russound R850MC is an 8-channel power amplifier ideal for use as the main amplifier in home theater and distributed audio systems. The eight channels are arranged in pairs to provide amplification for four stereo zones. The R850MC provides an array of useful features such as autosensing line inputs, bridged mono operation, independent zone triggering, bus inputs and multiple speaker outputs per zone to meet a wide variety of applications and configurations. The R850MC is rated at 50 watts per channel into 8 ohms and 80 watts per channel into 4 ohms. With a zone’s mode switch set in the Bridge Mono position, both channels in the zone are combined for a mono output of 140 watts into an 8-ohm load. All this power is supplied by two high-output toroidal transformers. Each output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
The R275HC is a 2-channel high-current power amplifier capable of driving low-impedance loads. It 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). This amplifier has a selectable low-cut filter designed to protect autoformer-based volume controls and speaker selectors. It also includes an autosensing input that activates the amplifier upon detecting an audio signal. The amplifier returns to standby mode when the audio signal ceases. 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.
The R235LS 2-channel amplifier has a space-saving low profile design with automatic local source switching capability. The R235LS allows a local source (e.g., PC or TV in the bedroom) to automatically override the speakers in that particular zone of a distributed audio system. This can be accomplished with its autosensing line input or with its trigger input for versatility in many different applications. The R235LS is rated at 35 watts per channel into 8 ohms and 50 watts per channel into 4 ohms. In bridged mode the R235LS is rated at 100 watts of power into a single 8-ohm load. Each amplifier output channel incorporates robust protection circuitry for safety and reliability under extreme circumstances.
