POWER
Please do not connect microphones to the mixer (or the stagebox/wallbox) as long as the
phantom power supply in switched on. Connect the micro-Phones before you switch on
the power supply. IN addition, the monitor/PA loudspeakers should be muted before you
activate the phantom power supply. After switching on, wait approx. one minute in order
to allow system stabilization.
The blue POWER LED indicates that the console in powered on.
LEVEL INDICATOR
The high-precision 4-segment display accurately displays the relevant signal level.
2.4 Main section
The red +48 V LED lights up when phantom power is turned on. Phantom power is required to operate
condenser microphones and is activates using the +48 V switch located above the +48 V LED.

Caution! You must never use unbalanced XLR connectors (PIN 1 to 3 connected) on the
MIC input connectors if you want to use the phantom power supply.

When the TAPE TO MIX switch is depressed, the 2-track input is assigned to the main mix providing
an additional input for tape machines, MIDI instruments or other signal sources that do not require any
processing.
CD/TAPE TO MIX
Press the CD/TAPE TO CTRL ROOM/PHONES switch if you want to monitor the 2-track input via the CTRL
ROOM OUT. This provides an easy way to monitor signals coming back from tape to ensure that they are
recording correctly.
CD/TAPE TO CTRL
If you are recording a signal via the CD/TAPE OUTPUT and wish to listen to this simultaneously via
the CD/TAPE INPUT, do not use the CD/TAPE TO MIX switch. Doing this would create a feedback
loop, since the signal would be routed, via the main mix, back to tape via the CD/TAPE OUTPUT.
To monitor the CD/TAPE INPUT, use the CD/TAPE TO CTRL ROOM switch to assign the tape signal
to the monitor(s) or headphones. This will avoid the tape signal being routed to the CD/TAPE
OUTPUT.
FX TO CTRL
If you want to monitor only the FX send signal in your headphones or monitor speaker(s), press the
FX TO CTRL switch. Now the signal of the effects processor can be monitored alone, and the main mix
and/or CD/tape signal is no longer present on the phone and control room outputs.
LEVEL SETTING
To correctly set the gains of the channels, first set the LEVEL controls of the input channels to their center
positions (0 dB) Then use the TRIM controls to increase the input amplification until signal peaks show 0 dB
on the level meter.
When recording to digital recorders, the recorder s peak meter should not go into overload. While analog
recorders can be overloaded to some extent, creating only a certain amount of distortion (which is common
and often desirable), digital recorders distort quickly when overloaded. In addition, digital distortion is not only
undesirable, but also renders your recording completely useless.
The peak meters of your ME display the level virtually independent of frequency. A recording
level of 0 dB is recommended for all signal types.
When recording to an analog device. the VU meters of the recording machine should reach approx. +3 dB
with low-frequency signals (e.g. kick drum). Due to their inertia VU meters tend to display too low a signal level
at frequencies above 1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10 dB. Since
drums should be driven to approx 0 dB.
MAIN MIX
Use the MAIN MIX fader to adjust the volume of the main out.
PHONE/CONTROL ROOM
Use the PHONE/CONTROL ROOM control to adjust the signal level of the CONTROL ROOM and PHONES
outputs.
