1 Balanced Direct Out (MBS Only): An electroni-
cally balanced low Z output. This is permanently set to
Pre-EQ.
2 Ground/Lift (MBS Only): This switch disconnects
the ground on the balanced, XLR output to eliminate hum
and buzz when connecting to equipment that is running
on a different ground system.
3 Input: A standard ¼" input jack to plug in active or
passive basses using an instrument (shielded) cable.
4 -14dB Pad: Reduces the input signal from your bass.
Press in if you hear distortion at low volume settings.
5 Volume: Sets the preamp gain after the input stage.
6 Low Cut: Rolls off the low end, producing a more
"vintage" tone reminiscent of the GK 400B.
7 Contour: Cuts midrange frequencies while boosting
lows & highs. Center frequency is 500hZ.
8 Presence: Adds edge and definition to higher frequen-
cies.
9 Treble: Boost and cut at 5 kHz +5dB/-22dB shelving
type.
10 Hi Mid Frequency (MBE Only): Sets the center
frequency for the Hi Mid control between 620Hz and
6.2kHz.

Optimized," band pass type.
12 Lo Mid Frequency (MBE Only): Sets the center
frequency for the Lo Mid control between 160Hz and
1.6kHz.

type.

16 Stereo Chorus LED (MBE Only): LED is lit when
the Stereo Chorus is engaged.

the Chorus effect.
19 Chorus Depth (MBE Only): Adjusts the depth of

22 Limiter On/Off: Press in to turn the Limiter on.
23 Limiter Level: Varies the power amp output from
20 watts to 150 watts. When using the limiter, start with
the adjustment knob turned fully clockwise. Turn the
knob counterclockwise to decrease distortion.
24 Effects Send (MBS Only): For the insertion of ef-
fects after the EQ, but before the boost section. May also
be used as a line out.
25 Effects Return (MBS Only): When the Return jack
is used, the Effects Loop is 'in series', meaning all of the
signal goes through the Effects Loop.
26 Phones: Stereo¼" output jack for private head-
phone listening.
27 Power/Protect LED: The LED is red for five seconds
while the amp powers up, then turns blue when the amp
is ready. Should the amp experience a fault (over heat,
over current) the amp will mute and the LED will switch
to red until the condition is corrected.
