[. . . ] The amplifier will be turned off, and the THERMAL LED illuminates until heatsink temperatures return to normal. At that time the amplifier automatically turns back on, and continues operating normally. NOMAD protection - The amplifier output MOSFETs are protected from excessive power dissipation by NOMAD protection circuitry. NOMAD (Non-Multiplying Advance Decision) limits the power when it measures signal voltage and current conditions that will exceed the pre-determined power limit of the MOSFETs. This instantaneous power calculation is performed on each output MOSFET, causing the amplifier to automatically limit power when needed. In this way, a speaker load with an impedance "dip" over a particular frequency range will only activate the NOMAD protection when sufficient audio is present at that same frequency range, but continue operating normally otherwise. Short protection - The NOMAD protection circuit also protects against shorts, and will instantly limit the output power if speaker wires are shorted together. 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". ­ 10 ­ Design Features FRONT VIEW REAR VIEW ­ 3 ­+ 1 2 + 600W 2 ­ 8 -- ® S R 2 6 0 0 Made in the U.

Recessed Front Panel - Prevents switches and controls from accidentally being adjusted or broken. Power Switch - Turns the amplifier ON and OFF 3. Power LEDs - Verifies that the amplifier channel is ON 4. Status LEDs - Displays the status of the amplifier. The LEDs are as follows: SIGNAL indicates if signal is present; CLIP illuminates if the amplifier is being overdriven; PROTECT illuminates if the amplifier is experiencing a "short" in the speaker array; THERMAL illuminates if the amplifier has shut down due an overheating condition. Female XLR & 1/4" TRS Input Jacks - Feeds input signal to the amplifier using industry standard male XLR or 1/4" TRS (tip/ring/sleeve) plugs. Male XLR Daisy Chain Jacks - Enables the connection of multiple amplifiers. [. . . ] Connect signal from source to CH B input. Biamp/Stereo switch not active (Stereo/Mono switch overrides this switch when in mono/70V/100V mode). Connect parallel array of 100V transformer-equipped speakers across the red terminals of the 5-way binding posts. (1200W ­ SR2600, 600W ­ SR2300) 6. [. . . ]
