About the Crate Acoustic CA125D:
D
esigned for the performing artist,
Crate’s CA125D Acoustic Amplifier
gives you more of what you want.
More power. More clarity. More control. And,
more freedom. Imagine: microphone quality
sound, without feedback. And without being
“chained” to a mic stand!
More power: twin 50-watt RMS power
amplifiers drive a pair of specially designed
high fidelity 8” low frequency transducers for
plenty of volume and low end punch.
More clarity: a separate 25-watt RMS
power amp drives a highly efficient Piezo
tweeter for clean crisp highs and natural
midrange blend. A tweeter level control on
the rear panel allows you to adjust the high
frequency output to suit your taste.
More control: three independent channels,
each with its own gain and reverb/effects
controls. The main Instrument channel features an “Active/Piezo” switch to properly
match the pickups of your instrument, plus a
three-band rotary EQ with variable contour –
for total control of the critical midrange frequencies. An easy-to-use feedback elimination
circuit with frequency select and cut controls
lets you kill feedback without sacrificing
sound quality. Plus a footswitchable chorus
with depth and rate controls.
The Vocal/Aux channel offers both low
and high impedance inputs for both kinds of
microphones, with phantom power on the
Low-Z input. The third “Aux” channel allows
the use of a rhythm machine, background
tape, or another mic or instrument.
Still more: The master section features
reverb and effects return controls, a five-band
graphic EQ, and the master level control. A
footswitch jack on the rear panel provides
control for reverb and chorus. Level-controllable XLR and 1/4” balanced line outs allow
you to patch into house sound boards or
recording consoles, plus an effects loop linein/line-out setup allows connection of external effects.
Enough already? Not for us. The CA125D
features Crate’s Digital Signal Processing (DSP)
for a variety of digital reverbs, effects and
delays specifically designed for acoustic
instruments.
The CA125D features a flip-out locking bar
underneath the cabinet which allows you to
tilt the amplifier back for increased coverage
and projection.
The CA125D was designed, evaluated,
tweaked and redesigned by musicians and
music loving engineers. Highly sophisticated
computer driven assembly machines and
highly skilled assemblers use only the finest
components to produce each amp. Every cabinet is hand-built and hand-covered by trained
craftsmen. The final assembled product is
tested – and played – by skilled musician/
technicians. It is only after the amplifier has
passed this barrage of picky people that it
gets packed up and shipped out.
The CA125D Acoustic Amplifier. Designed
to be its best, so you can sound your best!
To get this amplifier to sound its best,
read this user’s guide prior to its use.
To keep this amplifier looking its best, avoid
abrasive cleansers. Wipe the cabinet clean
using a slightly dampened cloth. Never use
brass cleaners on the hardware since they
could damage their protective coatings.
