1. Input Gain Control
This control adjusts the level of the input signal that is sent to the
equalizer. It provides between -15dB and +15dB of gain.
2. EQ Bypass Button
Pushing this button in removes the equalizer from your signal
path. The input gain and low cut filters are not affected, how-
ever.
3. Boost/Cut Range Button
This button selects which of the two boost/cut ranges the equal-
izer will use, either ±6dB or ±12dB. When pushed in, the ±6dB
option is used, and when released the ±12dB option is used.
4. Output Level Meter
These four LEDs indicate the output level of the equalizer. The
red clip LED marks the point 3dB before clipping occurs. If this
occurs, it's advised to adjust the input gain control to a point that
will cause this LED to flash only occasionally, or reduce the level of
any frequency sliders that may have excessively high signals.
5. Low Cut Button
When the low cut button is pushed in it will affectively reduce all
frequencies below 50 Hz in your signal at 12dB/octave.
6. Frequency Band Slider Controls
Each of these sliders will boost or cut the corresponding frequency
by ±6dB or ±12dB (depending on the settings determined by
the boost/cut button). All sliders are center detented, and this
position indicates that the corresponding frequency will have a
flat response. The frequency band centers of the GEQ3100 are
marked at 1/3 octave intervals at ISO standard intervals, whereas
the frequency band centers of the GEQ1500 are marked at 2/3
octave intervals on ISO standard intervals.

9. Output Connectors
These male XLR-type and 1/4" TRS phone jack connectors are
provided to send the processed signal to external devices.
10. Input Connectors
These female XLR-type and 1/4" TRS phone jack connectors are
provided to receive signals from external devices to be processed
by the GEQ equalizer. The maximum input level that the equalizer
can accept is +22dBu (ref: 0.775Vrms).
