Power Switch: To turn the equalizer ON or OFF , press the upper or lower portion of this button. CAUTION: Always turn on your equalizer BEFORE your power amplifiers are turned on , and always turn off your equalizer AFTER your power amplifiers have been turned off. 2. Filter `Level Controls: Each of these sliders controls the output level of each of the 15 bandpass filters. 3. Filter Range Switch & Indicators: The gain range of the filter sliders is switchable (as a group) from +/-6dB to +/12dB For maximum boost/cut capability. At 6dB the green LED will illuminate and at 12dB the yellow LED will illuminate. 4. Bypass Switch & Indicator: When the red LED is illuminated, this indicates that the unit or channel is in the bypass mode. Signal is routed directly from the input to the output without passing through any circuit (often referred to as "hard-wire bypass"). Use this switch to compare equalized and unequalized material, or to bypass the EQ section in the event of power loss or unit failure. 5. Overload Indicator: This red LED illuminates if any section of the equalizer is within 5dB of clipping. Occasional blinking of this LED is acceptable, but if it remains on more than intermittently you should turn down either the equalizer's level controls or reduce the output level of the preceding compon ent to avoid andible distortion. 6. Low-Cut Frequency Control: To cut down unwanted signal, this control determines the roll-off frequencyof the High-Pass Filter (HPF) in the instrument. The roll-off frequency cans de adjusted from 10Hz to 250Hz by turning this knob.
