1. OVERVIEW. 1-2. INTRODUCTION. The SR series integrated mixer/amplifiers have been designed for easy setup and simple but versatile operation. Requiring only the addition of microphones and speakers, the SR powered mixers are self-contained sound reinforcement systems, with features and performance generally found only in units costing much more.

2-3-3. REVERB RETURN TO MAIN CONTROL. This control determines how much of the signal from the reverb system is added or returned to the main mix. When the LED is illuminated, the phantom power is on. The 15 volts used for phantom power will run nearly all condenser microphones. 2-3-4. REVERB RETURN TO MONITOR CONTROL. Determines how much of the signal from the reverb system is added to the monitor mix.

channel is turned all the way down - otherwise a feedback loop will exist which could cause oscillation and possible damage to speakers. Care must be taken to insure that the amplitude of the return signal is not too great for the preamp channel input. An input pad may be used if needed. REVERB FOOTSWITCH. The Digital Reverb and Effects processer can be defeated by inserting an optional footswitch into the REVERB FOOTSWITCH jack. This allows the Reverb and Effects to be turned off and on remotely. 2-4-4.

allows the power amplifier to be used independently from the rest of the SR powered mixer. Possible uses of this feature include dedicating the power amp to the monitor system while employing an auxiliary power amplifier for the mains, or using the SR power amp as one of the two power amplifiers in a biamped system (this would require the addition of an external crossover). See Section 4-5. 3. REAR PANEL 3-1. SPEAKER OUTPUT JACKS(In Parallel). These are the speaker outputs for the built-in power amplifier.

• Use the highest quality patch cords available and keep them as short as possible. 4. Slowly attenuate the Equalizer control which has the greatest effect on reducing the ringing. This will take some trial and error - the first ringing usually occurs between 1 kHz and 4 kHz. Continue until the ringing has stopped. • Avoid patching a buss output back into its input. An example of this is patching a phase shifter from the EFF.
