INITIAL SETUP

1. after  opening  and  unpacking  the  GEQ  equalizer, 

inspect  the  unit  for  any  noticeable  damage. Though 
attempts  to  take  every  precaution  possible  in 
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. 

2. if you wish to mount the GEQ into a 19” rack, ensure it 

is not positioned above power amplifiers and that the 

unit has plenty of ventilation, as to avoid overheating. 

3.  plug  any  required  devices  into  the  GEQ’s  inputs  and 

outputs.  For  example,  a  mixer’s  output  signal  could 

be sent to the inputs, and an amplifier and speakers 

connected to the outputs.

4. plug the provided power cord into the power connector 

and  into  an  appropriate ac  power  source.  Be  sure 
to  check  local  voltage  levels  before  connecting  the 
unit.  Do  not  under  any  circumstances  defeat  the 
ground-pin of the cord, as it is provided for your own 
protection.

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 
signal sent through the subwoofer output, as well.
