Two KQ30s Stereo Operation
In this application you are using two KQ30s and will have the ability to equalize your Left channel independently
from your Right channel. This type of setup is employed by the ‘Die Hard’ competitors using equalization to move
the location of the sound stage in their car or my cousin Bernie who still claims he can hear grass grow.
Once you have your interconnect cables routed from your source unit to the KQ30s, simply connect the Left
channel RCA output from your source unit into the Left channel RCA input on KQ30 number 1. Now connect the
Left channel RCA output from KQ30 number 1 to the Left channel input of your electronic crossover or amplifier(s).
KQ30 number 1 is now the equalizer for just the Left channel of your system. (Fig. 1)
Next, take the Right channel RCA output from your source unit into the Left channel input of KQ30 number 2.
Now connect the Left channel RCA output from KQ30 number 2 to the Right channel input of your electronic
crossover or amplifier(s). KQ30 number 2 is now the equalizer for just the Right channel of your system. (Fig. 1)
Check the STEREO/MONO switch on both KQ30s and make sure
they are in the MONO (in) position. Also check the EQ/BYPASS
switch on both KQ30s and make sure they are in the EQ (out) posi-
tions. (Fig. 2)
**
When using the KQ30 in this setup the Right channel Output
of each unit is identical to the Left channel of that unit. This is
helpful if you need an additional Left or Right stereo channel out-
put to feed another device.
