esigned for the performing artist,
Crate’s CA112D 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 specially designed dual
voice coil 12” low frequency transducer 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 fea-
tures 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 fre-
quencies. 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-control-
lable XLR and 1/4” balanced line outs allow
you to patch into house sound boards or
recording consoles, plus an effects loop line-
in/line-out setup allows connection of exter-
nal effects.
Enough already? Not for us. The CA112D
features Crate’s Digital Signal Processing (DSP)
for a variety of digital reverbs, effects and
delays specifically designed for acoustic
instruments.
The CA112D was designed, evaluated, and
tweaked by musicians and music loving engi-
neers. Highly sophisticated computer driven
assembly machines and highly skilled assem-
blers use only the finest components to pro-
duce 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 CA112D Acoustic Amplifier. Designed
to be its best, so you can sound your best!
