-10 dB Pad/Clip indicator: Input attenuator
switch. This switch is generally set to the out
position except in cases where the clip LED
flashes more than occasionally. It may be
necessary to "pad" the input if you are using a
bass with active electronics or very high output.
The pad button light flashes red when the input is
being overdriven. If the -10dB is switched on and
the clip indicator still flashes frequently, reduce
the volume on your bass.
3
Gain: Sets the preamp gain after the input stage. It
is used in conjunction with the input pad to
optimize the amplifier's headroom.
4
Contour: As part of the amps active equalization
the contour switch decreases the mid-range
frequencies while boosting low and high
frequencies.
5
Treble: Boost and cut at 7 kHz +14 dB shelving
type. Use this control to add or remove edge and
definition.
6
Hi-Mid: Boost and cut at 1 kHz +6 dB. A "Q
Optimized," band pass type, this works on lower
string harmonics and effects the punch of your
sound.
7
Low-Mid: Boost and cut at 250Hz +6dB/-10 dB.
A "Q optimized" band pass type, this works for
main body of your sound.

type. This is used to control the low end push.

Power Button: Turns the amplifier on and off. In
the on position, the ring surrounding the button
will light red during power up then changes to
blue, indicating the amp is ready for normal

Aux In: This 1/8" input for a CD or MP3 player
allows the user to monitor an external audio
source.

Headphone/line out/chain out: When switched,
this output allows the user to send a direct
(unbalanced) line out to devices with unbalanced
inputs such as personal multitrack recorders. This
connection requires a shielded patch cord. The
Chain out allows the user to connect directly to a
GK MBP powered extension cabinet. This
connection is made with a balanced, tip, ring,
sleeve to male XLR cable.

Unswitched, this headphone jack can be used to
monitor your playing with headphones.

Headphone/line out/chain out switch: This
switch toggles the output from headphone to line
out.

Speaker: The power amp output to a speaker
cabinet delivers 200w into 4 Ohm loads. Lower
impedances such as 8 Ohms or 16 Ohms and no
load are acceptable. One 4 Ohm speaker and one 8
Ohm speaker is not recommended. A twist-lock 2
pin or 4 pin GK Speakon connector is required.
