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:
A. CONNECTING AC POWER TO YOUR MIXER
• Be sure to plug your mixer into the proper voltage marked
on your mixer, either
120V-60Hz
or
240V-50Hz
.
• Use only a grounded (3 prong) power outlet to prevent a
shock hazard (do not bypass). This gives the quietest ground-
ing for your mixer.
B. CONNECTING INPUTS TO YOUR MIXER
• For balanced microphones, use a shielded cable and plug
into the XLR
MIC
inputs.
• For high output devices like instruments & keyboards, plug
into the
LINE
input jacks using a shielded cable. Adjust the
channel
GAIN
control for mic or for instrument.
C. TURNING YOUR MIXER ON
• Set all channel and master
LEVEL
controls to their OFF
positions
• Set all
HI
,
MID
, and
BASS
controls and the
GRAPHIC
EQUALIZERS
to the center “flat - no boost or cut” position.
• Adjust all channel “
PAN”
controls to their center position.
• Connect your speakers and monitors at the rear panel.
• Turn the mixer on by the rear
POWER SWITCH
and watch
for the front
POWER
LED to come on. Your mixer is now
ready to operate by turning the levels up.
MIC CHANNEL FEATURES
1. XLR MICROPHONE INPUT
The
XLR MIC
input is designed for balanced low impedance
microphones. The high performance, low noise preamps do
a superb job of noise reduction. The XLR connector is wired
as per the industry standard, pin 1 is ground, pin 2 is non-
inverting (positive), and pin 3 is inverting (negative). Note:
Make sure the phantom power is switched off before con-
necting or disconnecting microphones to the mixer.
2. LINE INPUT JACKS
The
LINE
input is a 1/4” phone jack designed for balanced or
unbalanced line or instruments. Examples of these inputs
would be guitar, keyboard or effect returns. The line input
can be used at the same time the mic input is being used.
Channels 7/8 and 9/10 feature stereo LINE INPUTS for
stereo (use the top jack for mono input).
3. GAIN CONTROL (CHANNELS 1-6)
The
GAIN
control adjusts the input sensitivity on both the
LINE and MIC input jacks over a range of 40dB. For quietest
operation, set the
GAIN
control just below the point where
the
PK
LED flashes. If the PK LED lights or if distortion is
heard reduce the
GAIN
slightly until the PK LED is off.
4. CHANNEL “PK” LED
The
PK
LED indicates when the channel is nearing it’s clip-
ping level, causing distortion. Reduce the GAIN slightly to
prevent distortion. On channels 7/8 and 9/10, reduce the
level from your external souce. To get more volume,
increase the master MAIN control and re-adjust your main
mix.
5. CHANNEL LEVEL CONTROL
The
LEVEL
control adjusts the volume of the channel before
going to the PAN control. Here is where the individual
channel volumes are adjusted to make up the desired mix at
the main outputs.
6. CHANNEL BALANCE CONTROL
The
BAL
control places the channel between L and R in the
main stereo outputs. At the “0” center setting, the channel will
be heard equally from the L and R outputs.
When both 1/4” jacks are used on channels 7/8 or 9/10, the
BAL adjusts the L-R levels, sending signals from LINE 7/9 to
the LEFT, and signals from LINE 8/10 to the RIGHT.
7. CHANNEL EFFECTS 1&2 LEVEL
The
EFF 1&2
adjusts the level sent to the dual effects proces-
sor and to the front
EFF SND 2
jack. The effects control is
post-channel level, which automatically tracks the channel’s
LEVEL & EQ controls. Turning this control to the left will
send to the internal effects processor 1. Turning to the right
will send to the internal effects processor 2 (and the external
EFF 2 SND
jack). Center “0” is off. Reduce these levels if the
PK LEDs
are flashing on the effects processors.
8. CHANNEL MONITOR CONTROL
The
MON
control adjusts the volume of the channel going to
the master
MONITOR
control. The
MON
control is a pre-
LEVEL control. This means it is unaffected by the channel
LEVEL
.
9-11. CHANNEL TONE CONTROLS
Each channel features active 3-band EQ tone controls
LO
,
MID
, and
HI
. All three function as boost (clockwise) & cut
(counter-clockwise) controls. The center
0
is the “flat” or no
effect position. The
LO
and
HI
controls are shelving type
with corner frequencies at 80Hz and 11.5k Hz respectively.
The
MID
control is a band pass type centered at 750Hz.
These settings will vary with the type of voice or instrument.
Try reducing the
MID
to add clarity and turn up the
LO
and
HI
for a fuller sound. Channels 7/8 and 9/10 feature stereo
EQ controls.
12. TAPE IN JACKS (CHANNEL 9/10)
The
L-R TAPE IN
inputs on CHANNEL 9/10 are for connecting a
CD or tape player. These
TAPE IN
jacks can be used for return-
ing another stereo effects processor or instrument (keyboard).
Channel 9/10 inputs are NOT muted by the MUSIC BREAK
switch.
MASTER SECTION FEATURES
13. MAIN LEVEL (L & R AMPS)
The
MAIN
control is the master volume control for all chan-
nels. The
MAIN
signal is sent through the MAIN L-R
GRAPHIC EQ
to the
L
and
R
amps and the front
L
/
R
output
jacks.
14. MONITOR LEVEL (MONITOR AMP)
The
MONITOR
master level is sent through the MONITOR
GRAPHIC EQ
to the
MONITOR
amp and front output jack.
15. TAPE OUT LEVEL
The
TAPE OUT
LEVEL sends the
MAIN
signal mix to the
TAPE OUT
jacks for recording. The
TAPE OUT
level is unaf-
fected by the MAIN level control so a recording level can be set
independently of the MAIN speaker volume.
16. TAPE OUT JACKS
Use the
TAPE OUT L-R
jacks for recording or to send to
external power amps. If the TAPE OUT is being used to
record, make sure the TAPE IN jacks are not connected to
the recorder output or turn the channel 9/10 LEVEL to “0” or
feedback will result.
17. EFF 2 SEND JACK
The
EFF 2 SEND
jack can send a signal to an external proces-
sor. This is the same signal sent to the internal EFF 2 processor.
Effect returns can be connected to any input channel. Make
sure the EFF control for the return channel is set to “OFF” or
“EFF1” or feedback will occur.
18. MAIN L-R OUTPUTS
The
MAIN L
/
R
outputs are the same signals that feed the
internal LEFT and RIGHT amps. Use these balanced 1/4”
outputs to feed additional power amps, etc..
