OWNER’S MANUAL
BFX15
BASS AMPLIFIER
WITH
DIGITAL SIGNAL
PROCESSING
Congratulations!
You are now the proud owner of the compact but powerful Crate BFX15 Bass
Amplifier with Digital Signal Processing. The BFX15 offers a wide selection of digital
effects designed especially for the bass guitar , each of which are easily accessed with
a simple turn of a control knob. (No programmer’s degree required!)
The BFX15 is small in size but big in performance: the 8” Crate Custom speaker
makes the most of the amplifier’s 12 watts of musical output power. A 4-band rotaty
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 suitable for private practicing as well as performing in intimate surroundings.
Your BFX15 is designed by musicians and made in the U.S.A., using only the best
components. Extensive testing at the hands (and ears) of skilled technicians and
musicians ensures 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 read this manual before you begin playing.
And thank you
for choosing

1. INPUT: The signal output from an instrument
(active or passive) or a line level signal may be
connected here by means of a shielded instrument cable.
2. GAIN: This serves as the input signal level
control for the amplifier and controls the overall
output volume level.
3. LOW: Use this control to adjust the output
level of the low frequencies. This control has a
24dB range of cut or boost at 70Hz.
4. LO MID: Use this control to adjust the output
level of the lower-middle frequencies. This control has a 20dB range of cut or boost at 400Hz.
5. HI MID: Use this control to adjust the output
level of the upper-middle frequencies. This control has a 16dB range of cut or boost at 2kHz.
6. HIGH: Use this control to adjust the output
level of the high frequencies. This control has a
22dB range of cut or boost at 10kHz.
7. DSP MODE: Select the type of digital effect
applied to the signal with this control. The
effects are described as follows:
BYP ASS: No effects applied
DELAY: Slapback delay effect
ECHO: Long delay effect with regeneration
CHORUS: Chorus effect
FLANGE: Light flange effect
FUNK-WAH: Touch-sensitive wah-wah (“T-Wah”)
effect
OCT AVE: Adds secondary note one octave
lower than original note
ROOM: Small room reverb effect
HALL: Large hall reverb effect
8. HEADPHONES: For private listening, con-
nect a pair of stereo headphones into this jack.
The internal speaker is disconnected when
headphones are plugged in.
9. SPEAKER: Use this jack to connect the
amplifier to an external speaker with a minimum impedance rating of 4 ohms. The internal
speaker is disconnected when this jack is used.
WARNING: TO AVOID POSSIBLE
HEARING DAMAGE, DO NOT USE
HEADPHONES IN THE SPEAKER
JACK!
10. ON LED: This LED will illuminate when the
amplifier is turned on.
11. POWER: This switch applies AC power to
the amplifier. The amplifier is ON when the top
of the switch is depressed.
12. AC LINE CORD: Plug this cord into a properly wired, grounded, 120 volt, 60 cycle outlet.
DO NOT attempt to defeat the ground connection of this power cord! If your amplifier
was purchased outside of the United States,
see the unit’s rear panel labeling for its power
rating, and follow the above guidelines.
