OPERATING TEMPERATURE
Do not expose this unit to excessive heat. This unit is designed to operate between 32°
F and 104° F (0° C and 40° C). This unit may not function properly under extreme
temperatures.
WARNING: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture.
The lightning flash with an arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of un-insulated “dangerous voltage” within the products enclosure that may be
of sufficient magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
product.
GROUNDING INSTRUCTIONS
This product must be grounded (earthed). If it should malfunction or breakdown, grounding pro-
vides a path of least resistance for electric current to reduce the risk of electric shock. This product
is equipped with a supply cord having an equipment grounding conductor and a grounding plug. The
plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with the local codes and ordinances.
DANGER - Improper connection of the equipment grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the
product is properly grounded. Do not modify the plug provided with the product– if it will not fit the
outlet, have a proper outlet fitted.
The wires in this mains cord are colored in accordance with the following code:

Introduction
HIGH Input Jack
Using a standard guitar cable with a 1/4” jack - plug your bass into this jack. This input jack
was designed for passive basses (without batteries), however, you may plug your active bass
into this input for a higher gain structure.
LOW Input Jack
Using a standard guitar cable with a 1/4” jack - plug your bass into this jack. This input jack
was designed for active basses (with batteries), however, you may plug your passive bass into
this input for a softer gain structure.
DEEP Button
When the Deep button is pressed IN, a fixed EQ is applied to the preamp to give a BASS
boost to the sound of +8dB at 50Hz.
BRIGHT Button
When he Bright button is pressed IN, a fixed EQ is applied to the preamp to give a TREBLE
boost to the sound of +10dB at 10k Hz.
EQ Button
This button switches the EQUALIZATION section IN or OUT.
GAIN Control
The control adjusts the overall “GAIN” or distortion of the signal.
SHAPE Control
This control adjusts the overall tonal shape of the EQ. Turning the control clockwise will
increase the high frequencies. Turning it counterclockwise will provide a boost to the low
frequencies.

Front Panel
BASS Control
This control provides a 15dB of cut or boost at 100Hz. Rotating this control clockwise will
increase the lower frequencies and, depending on other settings, will generally make your tone
warmer and heavier.
MID-LOW Control
This control provides approximately 15dB of cut or boost at 220Hz.
MID (MIDDLE) Control
This control allows your getting 15dB of cut or boost at 660Hz. Turn it clockwise, the sound
will be fatter and more powerful.
MID-HI Control
This control provides approximately 15dB of cut or boost at 1.6K Hz.
TREBLE Control
This control provides a 15dB of cut or boost at 5k Hz. Rotating this control clockwise will
increase the high frequencies producing a brighter sound.
COMPRESSOR Control
This controls the amount of signal compression. At the full counterclockwise position there is
no compression. At the full clockwise position there is full compression. The sonic effect of
compression is reduced dynamics, increased sustain and a more consistent output level regard-
less of how light or hard the strings are played.
VOLUME Control
This control determiners the overall level (output) of the amplifier.
POWER - On/Off Switch
This turns the amplifier on and off. When the switch is “lit” then the amplifier is “on”.
COMPRESSOR Button
Use this switch to turn ON or OFF the Compressor.
SEND Jack
Use this 1/4″ unbalanced jack to send signal to a professional outboard effects processor. Out-
put level is approximately 0 dB to +4 dB and is post-EQ and post-shape but unaffected by the
setting of the volume control. It can also be used as a Line Out jack if required.
RETURN Jack
Use this 1/4″ unbalanced jack to return signal from a professional outboard effects processor.
This jack can also be used as a Line In Jack if required.
LINE OUT Jack
Use this jack for recording, direct to a PA system, or to a power amplifier.

AC POWER CORD
Using the included power cable connect the amplifier to a standard wall
outlet. See “Fuse Replacement” section for details on how to replace the
fuse.
SPEAKER OUTPUT Jack
The socket is situated on the rear panel of the unit. It connects to the in-
ternal speaker, you can also connect it to an external speaker cabinet.
COOLING FAN
It works with a speed controlled fan drive circuit. This reduces the
amount of fan noise as the fans run slow when the unit is cool and in-
crease in speed with output power demands.

Back Panel
We recommend that you use an authorized repair person to change the fuse
in this unit.
To access the fuse, first power down the unit and unplug the cable from the
wall outlet and the amplifier. Using a small screw driver, open the fuse tray
by prying open the small tab as shown in the drawing above.
Please note that the tray may not come all of the way out.
Remove the old fuse and replace with a comparable new fuse and close the
tray being sure that the tray snaps into position.
