The peak level of an audio signal is usually determined by the clipping level of electronic components. The following procedure should be used as a guide before the system installation is completed. Adjustment of source unit output and PAR-245 input: 1. Turn PAR-245 volume control fully counterclockwise. Turn source unit volume 1/2 to 3/4 of maximum. Adjust all PAR-245 input gains fully counterclockwise. Adjust the left input gain control clockwise until the input clip LED lights. Then adjust the control counterclockwise slightly until the LED doesn't light. This setting will minimize system background noise and prevents overloading the PAR-245. Repeat Step 5 for the right input gain control. There are separate left and right gain adjustments for each input which allows left/right balance adjustments. Adjust gains to minimum sensitivity (fully counterclockwise on the gain control of a PPI amplifier. ) 2. Turn the volume knob on the PAR-245 to the 3 o'clock position. Increase the gain on the amplifier until the onset of audible distortion. Repeat step 3 for any remaining amplifiers in the system. NOTE: In many multi-amplifier systems, the gain of some amplifiers may need to be further decreased to achieve tonal balance. 8 BACK TO CONTENTS SYSTEM TUNING Parametric Operation The PAR-245 Equalizer/Preamp puts an incredible amount of control at your fingertips. Correctly adjusted, it can solve many of the problems you will encounter along your road to perfect sound. By following these guidelines, you will avoid common pitfalls in system tuning and get your sound quickly dialed in. We recommend that you use a Real Time Analyzer (RTA) to speed things up, but it is possible to tune your system without it. It is important to understand what your equalizer actually controls to be able to use it effectively. On the face of the PAR-245 are five Boost/ Cut controls each corresponding to a range of frequencies.
