C1644P REAR PANEL FEATURES:
1 & 2. SPEAKER OUTPUTS
The
1/4” JACK
(1.), and
TWIST-LOK JACK
(2.) of each amp are wired in parallel.
The minimum load for each amp is 4 OHMS
.
Chaining together more than one speaker on an output is
fine as long as the total impedance is not below 4 ohms.
If the speaker load is lower than 4 ohms, the
amp may go into one of the PROTECT modes. (Two 8 ohm speakers in parallel = 4 ohms) 12 Gauge TWIST-
LOK speaker cables are an industry standard for high power applicattions (pin 1+ is POS,
pin 1- is NEG,
pins 2+ and 2- are not used).
The 1/4” jacks are used for lower power applications. Use only 16 gauge
(or heavier) speaker cables, NOT shielded instrument cables.
Turn power off before connecting speaker
cables.
3. AMP ROUTING switch
will select between two internally routed configurations:
OUT postion: AMP1-LEFT, AMP2-RIGHT, AMP3-MONITOR1, AMP4-MONITOR2
IN position: 1 amp each,
for Monitors 1 thru 4.
Speaker output levels are adjusted from the Left/Right faders or Monitor 1-4 controls.
The front panel
GRAPHIC EQs
function with the amps,
depending on the front panel EQ1 and EQ2 switch settings.
4. AMP PATCH INSERT jacks
offer full flexibility for mixer to amp signal routing.
These jacks are T-R-S
(Tip-Ring-Sleeve). Tip is the power amp input. Ring is the signal sent from the mixer determined by the
AMP ROUTING switch.
The limiters are post insert.
Patching a compressor or equalizer between the
mixer and the amp can be done by using a stereo insert cable (like Carvin’s
AP1
).
Connect the RING
signal to the INPUT of the external device, and the TIP signal from the OUTPUT of the device.
Plugging
in a standard 1/4” cable (mono) into the AMP PATCH INSERT jacks allows any external signal to be sent
to the internal power amps.
***
DO NOT
USE A BALANCED CABLE***
For example, you may want to patch the GROUP outputs (1-4) into the power amps.
-Plug one end of each cable into the GROUP jacks on the top panel of the mixer.
-Plug the other ends of the cables into the AMP PATCH INSERT jacks.
The GROUP 1-4 faders will now control what is heard at the SPEAKER OUTPUTS.
C1644P FRONT PANEL INDICATORS:
5. AMP
CLIP
LEDs
- The red CLIP LEDs will flash when the particular amp has reached it’s maximum
output. Occasional flashing caused by bass frquencies is OK. Consistent flashing caused by higher fre-
quencies may damage drivers due to excessive distortion.
This will not damage the amp.
6. PROTECT LED
- The yellow LED indicates the power amp system has gone into one of its protection
modes. There will be no output from the amps. If the amp output has been short circuited, or overloaded
by putting less than 4 ohms on the output the amp will go into protection.
Check for shorted speaker
cables and speaker impedance, then reset the POWER switch (off-on).
If the amp has overheated, lower
the volume and make sure the fan vents are not blocked.
Wait for the fan to cool the amps. Normal oper-
ation will return in about 1-3 minutes.

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 logically laid out making the powerful features simple to use.
The knobs have been located so that adjust-
ments 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 1 octave adjustments to tune in your overall 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.

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 in the headphones
before the fader is turned up.
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 (pre-graphic EQ) 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 bal-
anced.
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.
