C1644
CONCERT 44 SERIES
The C844, C1644(P), C2444 and C3244 feature 8 to 32 channels with true 4-bus
performance. The C1644P adds four 300 watt power amplifiers built into our ROAD WARRIOR case. Never before
have so many features been packed into such a rugged, compact USA made mixer. The best feature of the Concert
44 Series is the sound.
Sound that is pure and quiet enough for digital recording studios.
Everything is log-
ically laid out making the powerful features simple to use.
The knobs have been located so that adjustments
can be made quick and easy with visible pointers showing you the status of your mix at a glance.
TRUE 4-BUS DESIGN
The Concert 44 Series offers increased mixing flexibility over standard stereo con-
soles by letting you assign channels to one of the 4 sub groups or L/R.
This allows you to mix the entire drum,
horn, choir, etc. into one sub group, which feeds the L/R faders.
This is an easy way to control the volume of
grouped mics and inputs.
If you don’t need subgrouping, you can depress the L/R channel button and the
channel goes directly into the L/R output like a standard stereo console. All 4 sub group outputs have bal-
anced outputs for long cable runs.
TWO EFFECT SENDS / TWO 24-BIT EFFECT PROCESSORS
Two built-in 24-Bit effects, each offering
256 stereo effects, is a first in a 4-bus mixing console.
Since there are two, you no longer have to choose between
that great vocal reverb with delay and that awesome guitar chorus - you can have both!
Each processor offers
lush REVERBS, rich CHORUSES, thick textured FLANGING and pristine ECHOES with fully adjustable parame-
ters for damping, decay, depth, speed, time and regeneration.
Both processors can be sent back into the moni-
tor mix so the performers can hear exactly what the audience is hearing.
FOUR MONITOR SENDS
Every channel has 4 MONITOR sends with MASTER output level controls.
Monitor
send jacks are balanced TRS.
3 BAND EQ/MID SWEEP
The superb EQ system gives extended 15 dB boost and cut tone shaping.
The
LOW frequency control builds bass starting with 20 Hz through 80 Hz for a solid non-flabby low-end.
The exclu-
sive offset of the MID FREQ. control ends the confusion of selecting your mid frequency from 100 Hz to 5kHz.
The MID cut and boost control adjusts the gain to the perfect mid-dip or boost curve to enhance all instruments
and vocals. The 11.5k Hz HI treble control adds sparkle to your top-end without adding harshness.
Both the
LOW and HI are “shelving”, which means they are effective from 20 Hz and up to 20k Hz.
The LO CUT switch
eliminates stage rumble or other unwanted low frequencies that would normally rob power from your woofers.
TWO 9 BAND EQUALIZERS
Precision equalizers provide precise 1 octave adjustments to tune in your over-
all sound and control feedback.
Unlike one stereo equalizer, two independent 9 bands offers total flexibility.
With two convenient buttons, you can assign either EQ to the R/L outputs or to the 1/2 monitor outputs.
Center
frequencies are
63, 125, 250, 500, 1k, 2k, 4k, 8k & 16k Hz.
RECEIVING INSPECTION—read before getting started
INSPECT YOUR MIXER FOR DAMAGE which may have occurred during shipping.
If damage is
found, please notify the shipping company and CARVIN immediately.

In the event you have to re-ship your unit, always
use the original carton and packing material. This will provide the best possible protection during
shipment.
CARVIN and the shipping company are not liable for damage caused by improper pack-
ing.
SAVE YOUR INVOICE.
It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE.
If you find items missing, they may have been shipped separately.
Please
allow several days for the rest of your order to arrive before inquiring.
RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual for your

Keep your portion of the card and return the portion with your name and comments to us.
CHANNEL FEATURES
Every channel has a full balanced XLR and LINE (1/4”) preamp with an INSERT
jack for a compressor or EQ that also serves as a DIRECT OUT when plugged half way.
The PAN con-
trol directs the channel into the L/R output or any of the 4 sub groups after depressing the appropriate
ASSIGN switches.
A PFL (pre fader listen) switch allows you to hear the channel before the fader is
turned up in the headphones.
A solid “on” condition of the PEAK LED indicates that the MUTE switch
has been activated which turns the channel off including all monitor and effect sends.
When flashing
during use, the PEAK LED also lets you know when to adjust the channel’s GAIN control to prevent chan-
nel cliping.
The SIGNAL LED lets you know that a signal is coming through the channel starting at –20
dBu. A silky smooth 60mm audio taper FADER delivers professional fade-outs.
The PHANTOM power
switches provide power through the XLR connectors for use with condenser mics like the Carvin CM90E
in groups of 8 channels.
MASTER FEATURES
Each of the 4 SUB GROUP faders can be switched to the R/L outputs or used
independently through their own balanced output jacks.
Each of the sub group’s PFL switches allow you
to listen to the sub groups in your headphones before it is turned up.
The R/L MAIN output faders are
independent for added flexibility over a single stereo fader.
A MONO control sums both the R/L outputs
together for a center, side fill or subwoofer output.
The stereo HEADPHONE control tracks the METER
switches which allow you to look and listen from the L/R, MONO, MONITOR 1/2 and 3/4 outputs and
channel PFL switches.
The master section also features 2 EFFECT SENDS, 4 RETURNS and RCA TAPE
IN/OUT jacks.
All 4 SUB GROUPS, 4 MONITORS, XLR L/R and MONO outputs are balanced.
A FOOT
SWITCH jack turns both effects processors on or off remotely with the optional FS22 foot switch.
SWITCHING POWER SUPPLY
Our exclusive 125k Hz switching power supply eliminates trans-
former noise.
Like a laptop computer, go anywhere in the world and not worry about power because
you can run on any voltage from 90 to 250VAC. (
except C1644P
)
SUPERB SOUND
State-of-the-art low impedance, low noise preamps are featured on every channel.
The balanced common mode rejection is better than 70 dB to eliminate cable noise.
All main outputs are
balanced to guard against system noise.
The near theoretical limit on distortion has been achieved with THD
below .01% to guarantee the purity of your sound, ensuring it will be dynamically open and transparent.
ENGINEERED TO LAST
Hidden deep in the heart of these San Diego, CA
made mixers is the SMT con-
struction that utilizes surface mounted components to prevent malfunctions caused by vibrations.
Sealed
controls and switches guard against the outside elements while heavy-duty jacks provide a positive con-
nection to your cables.
Fire retardant FR-4 military spec circuit cards feature double-sided copper to elim-
inate radio frequency interference.
Precision 1% tolerance components guarantee your settings will be
accurate every time.
The Concert 44 Series is built to strict standards.
