ELEMENTS:
1
MONO CHANNELS (MIC/LINE)
The mono channels offer balanced XLR connectors for low-impedance micro-
phones and other low-level equipment. In addition, there are 6.3 mm TRS jack
input connectors for microphones and line level equipment (e.g., synthesizers,
drum computers, effects processors, etc.). Important: The MIC and LINE inputs
cannot be used simultaneously on the same channel. +48V PHANTOM POWER
The XLR inputs on the mono channels p48V phantom power for con-
denser microphones. Important: Never connect a microphone without phantom
power to the XLR input when phantom power is on.
2
INPUT GAIN ADJUSTMENT
The input gain control has two different scales: one for microphones and one
for line level devices. The outer ring (0 ~ 44 dB) refers to microphones, the
inner one (+15 ~ -30 dB) to line level devices. Always adjust the gain control
so that the peak LED above the channel fader lights up only occasionally. If the
LED is on constantly, this can lead to distortion.
3
LOW CUT FILTER
The LOW CUT button activates a low cut filter (75 Hz, slope 18 dB/octave) for
reducing low-frequency noise such as mains hum or handling noises from
vocal microphones.
4
STEREO CHANNELS
The stereo channels are configured as stereo pairs with 6.3 mm TRS jack
input connectors. Mono signal sources should be connected to the left jack
input connector.
5
+4dBu/-10dBV SELECTOR
The line inputs of the stereo channels have a button for selecting the input
sensitivity (+4 dBu for professional audio equipment, -10 dBV for general hi-fi
devices, etc.). If you are uncertain which setting to use for the respectively
connected device, first try +4 dBu. If the level is too low, switch to -10 dBv.
6
AUX SENDS
These 6.3 mm TRS sockets can be used to split the signal and send it additio-
nally to external effects processors or the like. In addition, these outputs can
be used as submix outputs.
7
PHONE
Headphones for monitoring the output signal (MAIN MIX) can be connected to
this TRS socket.
