FRONT PANEL DESCRIPTION

1

POWER switch.

Pressing the top half of this switch causes the mechanism contained within to connect power from the remote

power supply to the circuitry of the unit causing it to operate (ON). Pressing the bottom half snaps the switch to the opposite

operating mode (OFF).

2

SIGnal present indicator

illuminates green when an input signal greater than -20 dBm is applied to the unit, regardless of the

position of any controls on the unit, including the BYPASS switch.

3

OverLoad indicator

glows or flashes red when the signal passing through the unit is within 4dB of the maximum allowable level

at some point in the circuitry.

4

LEVEL s

ets the Level of the signal coming into the GE 30. Turn this control down if the OVERLOAD LED lights up steadily

(meaning too strong an Input signal). Since actual unity gain depends on varying slider settings (which is why we have not

marked a unity gain position on the front panel), use the BYPASS switch to determine the exact unity gain position of this

LEVEL control by comparing EQ and BYPASS loudness. Full counterclockwise rotation of this control provides full input attenu-

ation (signal off), full clockwise rotation yields a minimum of +6 dB of gain in the BOOST/CUT mode, or a minimum of +20 dB

of gain in the CUT-ONLY mode.

5

Overall BYPASS switch and indicator.

Pressing this button to its in and locked position provides a complete “hard-wire” bypass

of all active circuitry in the GE 30, including grounds. The GE 30 automatically switches to the Bypass mode in the event of a

power failure. This insures that should something fail in the power supply of the unit, signal passes to the rest of the system. The

indicator illuminates red when the GE 30 is placed in the Bypass mode via the switch.

6

Equalization controls.

These 60 mm slide controls set the relative level of boost or cut at each 1/3-octave frequency location. The

effect of each control is indicated by one of two calibration scales, the selection of which is denoted by an illuminated yellow LED

located at the top of the CUT-ONLY scale and at the center of the BOOST/CUT scale.

7

LOW CUT filter

control rotates in a clockwise direction to increase the frequency of the low filter cutoff. The calibrations on the

front panel indicate the -3 dB point of the filter. Rotating this control to its full counterclockwise position effectively bypasses the

filter.

8

HIGH CUT filter

control rotates clockwise to increases the frequency of the high cut filter cutoff. Like the low-cut filter, the

calibrations reflect the -3 dB point of the filter. Full clockwise rotation effectively bypasses the filter.

9

CUT-ONLY indicator

illuminates yellow when the EQ MODE select switch on the rear panel is depressed, placing the GE 30 in

its CUT-ONLY mode.

0

BOOST/CUT indicator

illuminates yellow, advising the operator that the rear mounted EQ MODE function select switch is in

its OUT position, placing the GE 30 in the + 12 BOOST/ -15 CUT mode.
