preventing damage occurring to its products in
transit, it is sometimes unavoidable. if the product is
noticeably damaged, users are advised to contact the
dealer at which they purchased the product.

is not positioned above power amplifiers and that the
unit has plenty of ventilation, as to avoid overheating.

outputs. For example, a mixer's output signal could
be sent to the inputs, and an amplifier and speakers
connected to the outputs.

CONNECTIONS AND CONTROLS
Front Panel
1.Output Level Meter
This 6-segment lED level meter (4-segment on the
GEQ1502F) will give you an accurate indication of when
the output level of the GEQ equalizer reaches certain
levels. if the red "clip" lED illuminates, users are advised
to reduce the level of that particular channel, either
through use of the input level control or by lowering the
frequency slide controls.
2. FB.D Switch
The FB.D Feedback Detection system is activated when
this button is pushed. When feedback is detected, an
lED will illuminate on the affected frequency's slide
control. users can lower the level of that frequency to
eliminate the feedback.
3. Audio In/Out Switch
pushing this button will enable and disable the equalizer
function for the respecting input channel. When the
equalizer is disabled, the input signal will be sent directly
to the output channel without being altered.
4. Range Switch
This switch is used to change the boost/cut range of
the frequency slide controls between ±12 dB and ±6 dB
(switch depressed).
5. Input Control
This control is used to adjust the input level for the
corresponding channel. it gives you a boost/cut range
between -15 and +15 dB.
6. Low Cut Switch/Control
The low-cut button on the GEQ1502F will remove
frequencies below 25 hz to help eliminate unwanted
stage rumble and other unpleasant low-frequency
sounds.
The GEQ3102F features a low-cut control that will allow
users to select the cut-off frequency of the low-cut filter
between 10 and 400 hz. please note that this affects the
