You are now the proud owner of the compact but powerful Crate BX-15 Bass Amplifier,
small in size but big in performance: the 8 Crate Custom speaker makes the most of the ampli-
fiers 12 watts of musical output power. A 4-band rotary EQ and built-in Limiter circuit give you
complete control over a wide variety of sounds. In addition, the front-panel headphone and
external speaker jacks make this amplifier equally suited for private practicing as well as per-
forming in intimate surroundings.
Like all Crate products, your BX-15 is designed by musicians, and built using only the best
components. Extensive testing insures you that this amplifier is the absolute best it can be.
In order to get the most out of your new bass amp, we urge you to check out the informa-
tion in this manual before you begin playing.
And thank you
for choosing

FRONT PANEL -“ MASTER SECTION
1: INPUT: Use this 1/4 jack to connect
your bass guitar to the amplifier by
means of a shielded instrument cable.
2: VOLUME:Use this control to adjust
the output level of the amplifier.
3: LOW:Use this control to adjust the
bass response of the amplifier.
Rotating the control counterclockwise
reduces the low frequency output.
Rotating the control clockwise increas-
es the low frequency output. It may be
necessary to reduce the Low frequen-
cy output at higher volume levels.
4: LOW MID: Use this control to adjust
the thickness: or fatness of the
amplifier. Rotating the control counter-
clockwise reduces the lower midrange
frequency output. Rotating the control
clockwise increases the lower
midrange frequency output.
5: HIGH MID: Use this control to adjust
the clarity and definition of the string
attack. Rotating the control counter-
clockwise reduces the upper midrange
frequency output. Rotating the control
clockwise increases the upper
midrange frequency output.
6: HIGH: Use this control to adjust the
high frequency response of the ampli-
fier. Rotating the control counterclock-
wise reduces the high frequency out-
put. Rotating the control clockwise
increases the high frequency output.7: EXTERNAL SPEAKER:Use this
jack to connect the amplifier to an
external speaker. The internal speaker
is disconnected when this jack is used.
The impedance of the external speak-
er must be 4 ohms or greater.
WARNING: Do not attempt to use head-
phones in the Speaker jack! Permanent
hearing damage could result!
8: HEADPHONES:Use this jack to
connect headphones to the amplifier.
The internal speaker is disconnected

loud levels.
9: ON LED:This LED illuminates
when the amplifier is turned on.
10: POWER:Use this switch to turn
the amplifier on (top of the switch
depressed) and off (bottom of the
switch depressed).
11: POWER CORD (rear panel, not
shown):The grounded power cord
should only be plugged into a ground-
ed power outlet that meets all applica-
ble electrical codes and is compatible
with the voltage, power, and frequency
requiremnts stated on the rear panel.
Do not attempt to defeat the safety
ground connection.
