The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. [. . . ] Normal operation will continue immediately after the short is removed. Power Supply Current Limiting protection- The switching power supply will protect itself from excessive power dissipation by continuously monitoring currents in the switching MOSFETs. The Current Limiting circuit measures the currents in the switching MOSFETs and will instantly limit them to a safe level. Soft turn-on/fast turn-off - Speaker loads are protected from turn-on/turn-off transients by a circuit that monitors the power supply, and controls the amplifier when power on/off events are detected. At turn-on, this circuit waits for power supply voltages to settle, then sends a turn-on ramp signal to slowly turn the amplifier on. At turn-off, this circuit acts quickly to turn off the amplifier before power supply capacitors discharge, and voltages collapse into the output signal - causing speaker "pops". ­9 ­ Design Features ­ SR2300, SR2800 FRONT VIEW REAR VIEW ­ 3 ­+ 1 2 + 600W 2 ­ 8 ­ ® S R 2 8 0 0 Made in the U.

Power LEDs - Verifies that the amplifier channel is ON 4. Mains Power Connector - Connects AC Voltage to the amplifier. The power connector is safety approved IEC type 320. The earth (safety) ground pin of the power connector is permanently connected to the chassis. This connection is capable of shunting in excess of 30A of fault current. Biamp/Stereo Switch - This dual purpose switch selects either standard 2-channel stereo mode or 1-channel in, 2 channels out Biamp mode. Turn amplifier off before operating this switch. Removable Rear Panel - 8 screws can be removed to service fans and internal components without unracking the amplifier. ­ 10 ­ Design Features ­ SR2300CE, SR2800CE FRONT VIEW REAR VIEW PIN 1+ 12+ 2SPKR CHA+ CHACHB+ CHBAudio GND 600W 2 ­ 8 ® S R 2 8 0 0 Made in the U.
