C44 SERIES CONTROLS
CHANNEL FEATURES
1. 1/4” LINE INPUTS
The line connectors are for connecting balanced and unbal-
anced instruments and line level sources such as drum
machines, keyboards, ETC.
2. XLR MIC INPUTS
The balanced Mic inputs are for connecting microphones that
use XLR connections. Both the LINE and XLR MIC inputs can
be used simultaneously.
3. CHANNEL INSERT/CHANNEL DIRECT OUT
To insert channel effects, compressor, etc. use a 1/4” TRS (Tip
Ring Sleeve) cable (see
INSERTS AND DIRECT OUT
illustration
on page 5 for TRS details). To achieve a direct out from the chan-
nel, insert a standard 1/4” cable to the first “click” (1/2 insert).
4. GAIN
The
GAIN
controls the input level for the channel. If the
GAIN
is set too high, the
PEAK
LED will flash and distortion may
occur. Decrease the amount of
GAIN
until the
PEAK
LED does
not flash. It is important that the gain control should be kept
right under the
PEAK
LED flash point to maintain the lowest
noise performance of the channel. You can use the channel
PFL
switch to monitor the channel input level and use the
meters to adjust the
GAIN
control to
0
dB. This will give you
a good reference point where the
GAIN
control should be set.
5. LOW CUT SWITCH
A 75 Hz
LOW CUT
filter helps eliminate unwanted low fre-
quencies. Great for reducing “boom” noise from mic stands
or from acoustic/electric guitars. Turning up the
LOW
EQ when
using this filter can help create a punchier bass response.
6. ACTIVE 3 BAND EQ
The
C44 SERIES
mixers provide studio EQ. The ±15 dB boost
or cut gives an overall 30 dB range for powerful EQ control.
The active circuits deliver deep bass from the 20-80 Hz
LOW
control. The
MID
control works at 100Hz to 5kHz, depend-
ing on the
MID FREQ
control. The
HI
control functions at 11-
20k for crisp highs.
Start out with all tone controls at their center “zero” posi-
tion. Determine which position your
MID FREQ
sounds best,
then cut or boost your
HI
,
MID
, and
LOW
frequencies as
needed. If you are trying to mic instruments such as acoustic
guitar or drums, try various mics and mic placement before
adjusting your tone controls. A typical setting may be:
HI +6,
MID -4
(
MID FREQ
set at
700Hz
), and
LOW +4
.
Don’t be afraid
to push the HI and LOW controls to get good presence and
depth while reducing the MID’s to clean up your sound. This
is the key to great sound.
7. MID SWEEP
This control allows you to select which frequency (from 100Hz
to 5kHz) that the
MID
control will boost or cut. Instruments
and singers have various tonal qualities. By adjusting the
MID
FREQ
, you can select the exact frequency that will best com-
plement these various inputs. 700Hz is a recommended set-
ting for the
MID FREQ
control for guitar and vocals.
8. 9. 10. MONITOR 1 THRU 4 CONTROLS
The channel MONITOR controls allow you to create four inde-
pendent monitor mixes. The
MONITOR
signals (pre-EQ, pre
fader) are routed to the master
MON 1, 2, 3
and
4
controls
(
#24
) respectively before going to the output connectors (
#39
).
To start, use
MON 1.
The
MON 2/MON 3
control will send
either to
MON 2
or
MON 3.
The center position is
OFF
. The
MON 4-ALT EFF 2
not only sends to the
MON 4
out but also
to the
EFF2
if the
EFF2/MON 4
switch (
#21
) is selected in the
master EFFECTS 2 processor. This provides two simultane-
ous effects per channel and the use of
MON 4
.
11. EFF 1/EFF 2 CONTROL
The
EFF 1/2
control will send a signal to
EFFECTS 1
or
EFFECTS 2
and to the
EFF 1-2
jacks (
#36
). The center posi-
tion is
OFF
. If BOTH effects are desired simultaneously for
all channels, press the MASTER EFFECTS 2
SOURCE
EFF2/MON4
switch (
# 21
) and use the
MON 4
channel send,
which will also send to the
MON 4
output (
#39
).
12. PAN CONTROL
Each channel’s
PAN
control allows stereo imaging by panning
Left or Right during recordings or live performances. The
PAN
control also works for the sub-mix groups. A center posi-
tion will send a channel’s signal to a pair of sub-group faders
(
1-2
,
3-4
when assigned). By panning hard left, the signal is
routed to only sub-group fader 1 or 3 when assigned. Panning
hard right routes the signal to sub-mix fader 2 or 4. Dual ele-
ment pan controls provide 15dB greater separation than
standard pan controls.
13. CHANNEL SIGNAL GREEN LED
The
SIGNAL LED
is pre-fader and post EQ. This LED helps the
operator verify that the channel is receiving a signal from the
mic or instrument inputs even when the channel fader is off.
14. CHANNEL PEAK RED LED
This peak indicator is pre-fader and post EQ. If the
PEAK
LED
flashes, the channel needs a reduction with the
GAIN
control
(
#4
)to prevent distortion. A “solid” lit
PEAK
LED indicates that
the channel has been
MUTED
.
C844, C1644, C2444 & C3244 4-BUS MIXERS
QUICK START UP
If you’re like most new owners, you’re probably in a hurry
to plug your mixer in and use it. Here are some brief instruc-
tions to get you going quickly. With the mixer unplugged and
the unit turned off, complete the following procedures:
1. CONNECTING AC POWER TO YOUR MIXER
• The mixer can be used with 120 or 240VAC (it automati-
cally switches internally)
• Use only a grounded (3 prong) power outlet to prevent a
shock hazard. This gives the quietest grounding for your mixer.
2. CONNECTING INPUTS TO YOUR MIXER
• For low level balanced devices such as microphones, plug
into the balanced
MIC
inputs using a shielded microphone
cable with XLR connectors.
• For high level balanced or unbalanced devices such as
instruments & keyboards, plug into the
LINE
input jacks using
a shielded cable with 1/4” phone plugs. Adjust the
GAIN
knob
for the mic or line input being used.
3. TURNING YOUR MIXER ON
• Adjust all channel
FADERS
and master
LEVEL
controls to
their OFF positions
• Adjust all channel’s
HI
,
MID
, and
BASS
controls and the
two master 9 Band
GRAPHICS
to their center position.
• Adjust the Channel “
PAN”
controls to their center position.
• Turn the mixer on by the rear panel
POWER SWITCH
and watch for the
POWER
LED. Your mixer is now ready
to operate.
