Strickland, VP Engineering Table of Contents DECLARATION OF CONFORMITY . . 21 ­1 ­ NOTICE - IMPORTANT SAFETY INFORMATION The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure, that may be of sufficient magnitude to constitute a risk of electric shock to persons. 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. [. . . ] 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". ­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.

Recessed Front Panel - Prevents switches and controls from accidentally being adjusted or broken. 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. The signal derived from the input signal is directly passed through (daisy chained) to these output jacks. Stereo/Mono Switch - This dual purpose switch is used to select the operating mode of the amplifier. In Stereo mode the amplifier can be configured for standard 2-channel stereo operation. In Mono mode the amplifier can be configured for Standard Bridge mono, 70V mono or 100V mono operation. Load Switch - Selects the speaker impedance or transformer voltage that will be connected the output binding posts. In Constant Voltage Mode the amplifier can drive an array of speakers using 70V or 100V transformers.
