CONTROL eLeMentS:

1
THE MONO MIC/LINE CHANNELS
You can connect balanced, low impedance microphones or a low
level signal to the XLR socket. on the 1/4 " line jack you can connect
either a microphone or a line level instrument such as synthesizers,
drum machines, effect processors or any other line level signal.
Note: You shall never connect an unbalanced microphone to the XLR
socket if you do not want to damage both the microphone and mixer.
Also, it is not possible to simultaneously use both the MIC & LINE
inputs on the same channel, use only one of them for the appropriate
source.
2 INPUT LEVEL SETTING
This control is provided with 2 different indication rings: one is for
the microphone and the other for the line level. When you use a
microphone you shall read the OUTSIDE ring (0~40dB), when you
use a line level instrument you shall set this control in a way that the
peak LED will blink also occasionally in order to avoid distortion on
the input channel.
3 LOW CUT SWITCH
By pressing this button you will activate a 75Hz low frequency filter
with a slope of 18 dB per octave. You can use this feature to reduce
the hum noise caused by the mains power supply, or the stage
rumble while using a microphone.

They are organized in stereo pair and provided with 1/4 '' TRS so-
ckets. Use the left input if connect a mono input signal to the STEREo
INpUT.
5 +4dBu/-10dBV
These switches select the input sensitivity of the line inputs on the
stereo channels. +4dBu is suitable for professional audio devices,
-10dBV is suitable for general HI-FI devices.If you are not sure which
setting to use, try at first +4dBu,if the volume level is too low change
it to -10dBV.
6 AUX SENDS
