gain controls are bypassed.

LOW CUT (3)

A high pass filter, continuously variable from 5 Hz to 200 Hz. Low frequency roll-off is at 12 dB per octave. Adjust this control to approximate low frequency cut-off of speaker system.

HIGH CUT (4)

A low pass filter, continuously variable from 5 kHz to 35 kHz. High frequency roll-off is at 12 dB per octave. Adjust this control slightly above high frequency system limitation.

LED LEVEL METER (5)

This multicolored LED ladder indicates output level.

GAIN (6)

Calibrated control for regulating overall gain of the equalizer section. Unity gain throughout the signal chain may be maintained by recovering lost signal at this point. Example: Assume the equalization process has introduced a signal loss of -6 dB by negative (-) adjustment of the EQ section. The gain should then be adjusted to +6 to maintain unity gain through the equalizer.

EQUALIZER SECTION (7)

31 bands of 1/3 octave filters. The filters are constant “Q” devices, located at ISO center frequencies. Effective equalization range is from 20 Hz to 20 kHz. Maximum cut or boost per frequency is 15 dB.

AUTOMATIC FEEDBACK LOCATING LEDs (8)

When feedback occurs, the LED of the frequency band that is feeding back will illuminate indicating feedback in that band. The LED will remain illuminated for a few seconds even after the feedback is gone. This is to allow you to see where the feedback is if the feedback goes away before any correction is made. If there is no feedback occurring, the LED of the frequency band with the most energy in it will illuminate. Just because the LED is illuminated does not mean that there is feedback occurring. For best performance of the automatic feedback locating system, use an input signal of 0 dB (1V RMS).
