Basic Setting Of The Input Channels; Mixing Of The Audio Sources; Talkover Function; Monitoring Via Headphones - IMG STAGELINE MMX-602/SW Mode D'emploi

3) Connect the power amplifier for the speak-
ers or a subsequent unit with line input
(main mixer, effect unit, etc .) to the matching
output jacks:
a unit with XLR input to the XLR jacks L /A
and R / B (19) and / or
a unit with RCA input to the phono jacks
L /A and R / B (20)
4) A recording unit for audio recordings can
be connected to the phono jacks REC (21) .
The re cord ing volume is independent of the
adjustment of the output level controls (14) .
The record ing is made independent of the
position of switch STEREO / MONO (13), i . e .
it is always stereo phonic .
5) Headphones can be used to monitor the
output signal of the mixer . For this purpose,
connect headphones (minimum impedance
2 × 8 Ω) to the 6 .3 mm jack
6) Finally connect the mains plug of the cable
(18) to a mains socket (230 V/ 50 Hz) .
4.1 Switching on the microphone
phantom power
To be able to operate phantom-powered micro-
phones as well, it is possible to switch on a 12 V
phantom power separately for each microphone
input .
Attention! To switch on the phantom power,
the mixer must be opened . This must only be
done by qualified personnel .
1) Disconnect the mains plug from the mains
socket .
2) Screw off the housing cover .
3) For the desired microphone inputs, rearrange
the corresponding jumpers JP101 (for chan-
nel CH 1) to JP601 (for channel CH 6) from
Off to On, as shown in fig . 3 .
4) Tightly screw on the housing cover again .
5 Operation
1) Prior to switching on, the output level con-
trols (14) should be set to zero to avoid a
possible switching-on noise .
2) Switch on the unit with the POWER switch
(17) . The red power indication (5) lights up .
3) Switch on the connected units, always switch
on the power amplifier for the speakers last
of all .
4) When switching off the system, always
switch off the power amplifier first .

5.1 Basic setting of the input channels

1) First set the six channel level controls LEVEL
[front rotary knob (9)] to zero and the six
balance controls BAL [rear rotary ring (10)] to
mid-position . Set the equalizer controls LOW,
MID, and HIGH (12) likewise to mid-position .
2) Select the desired input for each channel with
the input selector switch LINE / MIC (11):
button pressed: the microphone input is
selected via the XLR jack (23)
not pressed: the line input is selected via the
phono jacks (22)
3) Select the operating mode with the selector
switch STEREO / MONO (13):
button pressed: mono operation; the mono
output channels A and B are available with
the same mixing signal
not pressed: stereo operation; a stereo out-
put channel LEFT / RIGHT is available

5.2 Mixing of the audio sources

1) Do not switch on the talkover function for
the time being, i . e . the button OFF/ ON (7)
must not be pressed .
2) Feed a signal to all connected inputs (test sig-
nal, music piece, or microphone announce-
ment) .
3) To be able to hear a signal via the output,
turn the output level controls LEFT/A and
RIGHT/ B (14) approx . to position 7 for the
time being .
4) Turn up the front rotary knob LEVEL (9) of the
(16) .
channel(s), which are to be heard at highest
volume, until the indication PEAK (3) shortly
lights up with the music peaks . Slightly turn
back again the control(s) .
5) Add the remaining channels which are to be
heard as well with the corresponding rotary
knobs LEVEL accordingly .
6) If the MMX-602 / SW is in stereo operation
[button STEREO / MONO (13) not pressed],
adjust for each channel with the rear ro-
tary ring BAL (10) either the balance of the
stereo signal of the RCA jacks or apply the
microphone signal to the desired spot in the
stereo basis .
7) Adjust the sound with the controls (14):
LOW for the bass range
MID for the midrange
HIGH for the high range
8) Adjust the output level with the controls
LEFT/A and RIGHT/ B (14) so that the yellow
0 dB LEDs of the level indication (4) light
up with music peaks . However, if the input
of the subsequent unit (amplifier, mixer) is
overloaded by this, turn back the controls
correspondingly .
In stereo operation, adjust the balance
of the mixing signal with the output level
controls (14) at the same time . In mono
operation, a different level for the outputs
A and B can be adjusted with the controls .

5.3 Talkover function

With the talkover function, the audibility e . g . of
an announcement via channel CH 1 or CH 2 can
be improved if the volume of the other channels
is automatically attenuated by 12 dB during the
announcement .
1) Switch on the talkover function with the
button OFF/ ON (7) . The indication ON (1)
lights up .
2) Select with the selector switch CH 1 + 2 / CH 1
by which channels the volume of the other
channels is to be attenuated:
button pressed: if a line signal is present at
channel CH 1 or if a microphone announce-
ment is made via channel CH 1, the volume
of channels CH 2 to CH 6 is attenuated
not pressed: if a line signal is present at
chan nel CH 1 or CH 2 or if a microphone
announcement is made via one of these
channels, channels CH 3 to CH 6 are atten-
uated .
3) Feed a signal to channel CH 1 or CH 2 (e . g .
an announcement via microphone) and turn
up the control SENS (6) until the indication
ACTIVE (2) lights up during the announce-
ment . The indication ACTIVE always lights
up in case the corresponding channels are
attenuated .
Note: If the control SENS is turned up too much,
the volume attenuation can already be released by
interfering noise . If the control is not turned up far
enough, there is either no volume attenuation at
all or only in case of high volume signals .

5.4 Monitoring via headphones

Via headphones connected to one of the jack
(16), the mixer output can be monitored .
Adjust the headphone volume with the control
LEVEL (15) .
CAUTION Never adjust the headphones to
a very high volume . Permanent
high volumes may damage your
hearing! The human ear will get
accustomed to high volumes which do not
seem to be that high any more after some
time . Therefore, do not further in crease a high
volume after getting used to it .
The headphone volume is independent of the
output level controls (14) . Thus, it is possible to
monitor the signal even if the output controls
are set to zero .
