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.

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.

SOUND CHECK In a live sound reinforcement system, the input signals to the mixer will come from the micro- check. A good thing to also check here is feedback in the monitors from the microphones. Good phones and instruments. Each microphone or instrument must be connected to one of the mixing positioning of the monitors and the use of a graphic equalizer solves most major monitor feed- console inputs. -
