Manual-2FRONT PANEL DESCRIPTION POWER LED illuminates whenever the appropriate power supply is connected to the unit with the correct line voltagesource. Channel BYPASS switches and LEDs: When the BYPASS switch is in the in position the red BYPASS LED illuminatesand the channel is in the BYPASS mode. In this mode the audio signal is routed directly from the INPUT to the OUTPUTjacks without passing through any active circuitry (often referred to as hard-wire bypass). Use this switch to compareequalized and unequalized material. In the event of power failure, the GE 215 automatically goes into BYPASS. Channel OVERLOAD indicators illuminate if any section of the same Channel of the GE 215 is within 3 dB of clipping.Occasional blinking of this LED is acceptable, but if it remains on more than intermittently, turn down either the Channel’sLEVEL control or reduce the output level of the preceding component to avoid distortion. Channel LEVEL controls set the Level of the signal coming into the GE 215. Turn this control down if the OVERLOADLED lights up in it’a Channel steadily (meaning too strong an Input signal). Since actual unity gain depends on varyingslider settings (which is why we have not marked a unity gain position on the front panel), use the BYPASS switch todetermine the exact unity gain position of this LEVEL control by comparing EQ and BYPASS loudness. Filter Level slide controls set output levels of each of the 30 bandpass filters for each Channel.
