Functions
1.Mic
Electronically balanced XLR-type inputs for connecting low-
impedance microphones. The input provides extremely low noise
and low hum signal processing. When connecting a microphone
make sure that the pin assignment is correct. Always make sure to
read the manual of the microphone you want to connect. The XLR-
inputs are not suitable for connecting line level signals like an
additional mixing console, FX-unit, etc. You have to use the LINE-
inputs, when connecting this kind of equipment.
2. Line
Electronically balanced inputs for connecting a keyboard, CD
player, mixer, etc. You can connect balanced or unbalanced
signal sources to the Line input. Do not connect signal devices to a
channel’s MIC and LINE input at the same time. This will cause
mutual interference, which results in level reduction.
Note: When connecting signal sources, please make sure that the
corresponding channel faders and the master faders are at their
minimum settings. Otherwise plug-in noise can occur.
3/ 5. LINE in
Unbalanced stereo inputs for connecting a keyboard, CD player,
mixer, etc. You can connect unbalanced signal sources to the Line
input. When using a mono device, always connect it to the Left
(mono) input.
Note: When connecting signal sources, please make sure that the
corresponding channel level controls and the master mix control
are at their minimum settings. Otherwise plug-in noise can occur.
4. Trim
Mic Channel input level is determined by the Gain control. With the
Gain control you can adjust the MIC or LINE input-sensitivity, while
optimally matching the incoming signals to the mixer’s internal
operation level. The high gain of this mixer is ideal when dealing
with very low input levels (i.e. vocal recordings or distant sound
sources).
How to set the Input level:
1)
Set the trim control and the corresponding level control to their minimum setting.
2) Connect the desired sound source (CD player, microphone, etc.) to the corresponding mic or line
input.
3) Play the sound source at its highest volume setting; respectively, sing or speak as loud as possible
directly into the microphone.
4) While doing so, adjust the input level using the gain control, so that during the loudest passages the
peak LED (11) only blinks occasionally.
This basic channel setting leaves you at least 8dB headroom. This means, you have at least 8dB before
signal clipping. If you want to make further adjustments to the channel’s EQ setting, you should repeat
step
3 and 4 again.
