Neo Series Bass Combo Amplifi er
Horn Bi-Amp System
Horn Bi-Amp Mode: This mode requires a GK
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 HBA compatible enclosure to Bi-Amp.
In this mode, the cabinet’s internal crossover is
bypassed. Use the Woofer/Main knob to control the
ouput signal to the woofer, and the Tweeter knob to
control the ouput signal to the horn.
Note: The 50W horn amplifi er has a fi xed frequency
output of 5kHz and up (high frequencies only). It
will not provide a useable signal to drive a seperate
speaker cabinet.
Fullrange Mode: This mode is compatible
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
HBA compatible enclosure, set the switch on
the back of the cabinet to Fullrange. 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 amplifi er
to control your output level. The Tweeter knob is
not used.
Note: To avoid the risk of damage to the amplifi er,
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!!!

Horn Bi-Amp System:
Your amplifi er incorporates GK’s unique Horn Bi-Amp System. This feature is automatically engaged
when you connect to a GK HBA compatible enclosure, giving you completely 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
Tweeter and Woofer Master controls on the amplifi er’s front panel.
