Congratulations!

You are now the proud owner of the compact but powerful Crate BX-25 or BX-50

Bass Amplifier. The small size of each amplifier belies its big performance: the Crate

Custom speaker makes the most of the amplifier’s musical output power: 27 watts

into a 10” speaker for the BX-25; 50 watts into a 12” speaker for the BX-50. A4-band

rotary EQ combined with Crate’s variable Contour gives you complete control over a

wide variety of sounds. In addition, the front panel headphone and extension speak-

er jacks make this amplifier equally suited for private practicing as well as perform-

ing in intimate surroundings.

Like all Crate products, your BX-25/BX-50 is Musician Made in the U.S.A., using

only the best components. Extensive testing at the hands (and ears) of skilled tech-

nicians and musicians 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

information in this manual before you begin playing.

And thank you

for choosing

BX-25/BX-50 BASS AMPLIFIER

BX-25/50 Bass Amplifier

3 4 5 6 7 8 9 10 1312 1411 15

1: 0dB INPUT: Connect your bass here if it has “normal” pickups

and no active electronics. This sends a full strength signal into the

amplifier. If your bass has active electronics or high output pickups,

or if the amp sounds like it’s distorting try the -15dB Input (#2).

2: -15dB INPUT: Connect your bass here if it has active electron-

ics or high output pickups. The output signal will be attenuated by

15dB to keep it from overloading the amplifier’s input stages.

3: GAIN: This serves as the input signal level control, allowing you

to set the amplifier for the best signal to noise ratio.

4: CONTOUR SHAPE: This control is only active when the

Contour Active switch (#5) is pressed in. The setting of this control

shifts the frequency where the contour effect is centered, giving

you a wide variety of tonal variations, from a studio “V”-shaped

tone to a more “live”, more present sound.

5: CONTOUR ACTIVE: When this pushbutton switch is pressed in

the Contour Shape control (#4) is activated and the sound of your

bass is affected by the setting of the control. Pressing the switch in

a second time releases it, deactivating the Shape control.

6: LOW: Adjust the output level of your low-bass tones with this

control. The center position is “flat” (no boost or cut). Turning the

control to the left reduces the output level of the low frequency

tones; turning it to the right increases their level. This control allows

a 28dB range of boost or cut at 60Hz.

7: LOW MID: Adjust the output level of your lower midbass tones

with this control. The center position is “flat” (no boost or cut).

Turning the control to the left reduces the output level of the lower

midbass tones; turning it to the right increases their level. This con-

trol allows a 15dB range of boost or cut at 400Hz for the BX-25;

150Hz for the BX-50.

8: HIGH MID: Adjust the output level of your upper midbass tones

with this control. The center position is “flat” (no boost or cut).

Turning the control to the left reduces the output level of the upper

midbass tones; turning it to the right increases their level. This con-

trol allows a 18dB range of boost or cut at 1kHz.

9: HIGH: Adjust the output level of your high frequency overtones

with this control. The center position is “flat” (no boost or cut).

Turning the control to the left reduces the output level of the high

frequency overtones; turning it to the right increases their level.

This control allows a 33dB range of boost or cut at 10kHz.

10: MASTER LEVEL: The output level of the internal speaker,

headphone jack and extension speaker are governed by the set-

ting of this control. At the full left position there will be no output;

rotating the control to the right increases the output volume level.

11: LIMIT: When a power amplifier reaches maximum output lev-

els it may begin to “clip” its output signal which generates poten-

tially speaker-damaging distortion. The BX-25/50 has a special

APM (Automatic Power Maximizer) limiting circuit which helps

minimize this problem by monitoring the power amplifier’s output

signal, keeping it below clipping. This feature insures you that the

sound from your amplifier remains clean and pure even at full

power. The APM indicator will only light when the amplifier is near

clipping; flashing at peak playing levels is acceptable, however if

the light remains on constantly reduce the Master Volume until the

light flashes.

12: HEADPHONES: For private practice sessions, plug a pair of

stereo headphones into this jack. The internal speaker is discon-

nected whenever headphones are being used.

13: EXTENSION SPEAKER: You may connect the BX-25/50 to

an external speaker with a rated impedance of 4 ohms or more

using this jack. The internal speaker is disconnected from the

amplifier when the Extension Speaker jack is used.

14: ON LED: The word “ON” will glow when you turn the amplifier

on showing you that the amplifier is activated and ready to play.

15: POWER: This heavy duty rocker type switch is used to turn the

amplifier ON in the up position, OFF in the down position. The ON

LED (#14) works with this switch as a visual indicator.

16: POWER CORD: (Rear panel, not shown) This heavy duty,

grounded, three wire power cord is to plugged into ONLY a

safely wired, grounded 120 volt, 60 cycle AC power outlet. DO

NOT attempt to defeat the ground connection of this cable!

If your BX-25/50 was purchased outside of the United Stated,

see the unit’s rear panel for its power rating and follow the

above guidelines.

WARNING: DO NOT attempt to use head-

phones in the Speaker jack! Permanent

hearing damage could result!

The BX-25/50 is covered with a durable black Tolex material: wipe it clean with a lint-free cloth. Never spray

cleaning agents onto the cabinet. Avoid abrasive cleansers which would damage the finish.

El BX-25/50 esta cubierto con un material durable Tolex: limpielo con una toalla seca. Nunca rocie el gabinete

con sustancias limpiadoras. Evite usar materiales abrasivos con los cuales pueda danar el acabado.

Le BX-25/50 est couvert avec «Tolex» un recêtement noir et durable. Essuyez cette matière avec une toile pro-

pre et sans charpie. Ne pulvérisez jamais les agents de nettoyage sur l'appareil. Evitez les nettoyeurs abrasifs

qui peuvent endommager le «Tolex.»
