Horn Bi-Amp System (HBS):
Your amplifier incorporates GK's unique HBS. This feature is automatically engaged when you con-
nect to a GK HBS compatible enclosure, giving you independent control of the tweeter and woofer
signals. Now you can push the woofers to the max while the tweeter remains clean, crisp, and free of
clipping distortion. A smooth tight tone is easily dialed in by adjusting the Horn and Woofer Master
controls on the amplifier's front panel.
Horn Bi-Amp Mode:
Horn Bi-Amp compatible bass cabinet. Use a
properly wired four-conductor Speakon cable to
connect to your cabinet. Set the switch on the back
of your GK HBS compatible enclosure to Bi-Amp.
In this mode, the cabinet's internal crossover is
bypassed. Use the Woofer/Main knob to control
the output signal to the woofer, and the Horn knob
to control the output signal to the horn.
Note: The 50W horn amplifier has a fixed frequency
output of 5kHz and up (high frequencies only). It
will not provide a usable signal to drive a separate
speaker cabinet.

BI-AMP MODE
FULL RANGE MODE
This mode requires a GK
Full range Mode:
with virtually any standard bass cabinet. Use a
two-conductor Speakon cable or a ¼" speaker
cable to connect to your cabinet. If using a GK
HBS compatible enclosure, set the switch on the
back of the cabinet to Full range. In this mode,
the cabinet's internal passive crossover is used to
split the signal between the woofer and horn. Use
the Woofer/Main knob on the front of the amplifier
to control your output level. The Horn knob is not
used.
Note: To avoid the risk of damage to the amplifier,
do not use a four-conductor Speakon cable with non
GK cabinets. Instead use a two-conductor Speakon
or ¼" speaker cable.
CAUTION:
UNDER NO CIRCUMSTANCES
SHOULD THE WOOFER/MAIN AMP AND
THE 50 WATT HORN AMP BE CONNECTED
TOGETHER!!!
