R275HC 2-kanaals versterker

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.
