your instrument. It is intended for bass guitar but will
accept other instruments as well.
b Active/Passive Switch
k Normal / Sub Switch:
Set this switch to Active when using an active bass
guitar. Setting to Active will lower the input gain by
12 dB.
When this switch is set to Normal, the Bass Control
frequency is centered at 100Hz. When this switch is
set to Sub, the Bass Control frequency is centered at
50Hz.
c Gain Control:
Adjust clockwise to increase the amount of preamp
volume. When set too low, the Signal Indicator will
not light.
l Normal / Shift Switch:
When this switch is set to Normal, the Mid Control
frequency is centered at 800Hz. When this switch is
set to Shift, the Bass Control frequency is centered
at 400Hz.
d Clip Indicator:
Indicates when the input signal has reached
maximum level. Note: The Active / Passive Switch
is the only control on the amplifier that has an effect
on this. If the switch is set to Active and the Clip
Indicator still lights, lower the output of your
instrument to correct.
m Normal / Define:
When this switch is set to Normal, the High Control
frequency is centered at 3KHz. When this switch is
set to Define, the High Control frequency is
centered at 5KHz.
n Graphic Equalizer Section:

When this is active, the signal to the power amp will
be boosted by 6dB. Note: When using the
footswitch, this button will be disabled.
h Bass Control:
Controls the amount of low frequency in the signal.
The Normal / Sub Switch changes the center
frequency for this control. (See k)
s Power Jewel:
Indicates when AC power is applied to the amplifier.

signal will be unaltered by the EQ sections of the
preamp. When set to Post EQ, the Direct Output
Jack signal will reflect the entire sound (including
EQ settings) of the preamp. Note: The Master

authorized service center for repair.
{ Effects Send Jack:
Use this jack to connect to the input of an external
effects processor. This jack can also be used as a
preamp out.
v Speaker Output:
This jack is used to connect the amplifier to
internal speakers, or an external speaker cabinet,
using a heavy duty Speakond speaker cable.
Note: To prevent overheating and possible loss of
signal, do not connect a load lower than 2 ohms.
(To connect a cable: Align tab on speaker cable
connector slot. Insert and twist one quarter turn
clockwise to lock. To remove a cable: Pull back
release button on cable connector, twist connecter
counter clockwise one quarter turn, and pull out
