CH1~CH4 INSERT:
2
These four INSERT are a break point in the input channel signal path. It allows the signal to be taken
out from the mixer, through an external equipment such as a compressor, and than back to the mixer
to continue the final mix output.
The stereo channel(A)
1
MIC microphone input
This is an XLR type balanced connector for microphone,the input level range: -60~-
20dB. At this channel the amplified signal will be feed to the L/R main bus equally finally.
ST LINE IN Line
input
:
2
This is one unbalanced phone jacks to which line level devices can be connected, the
rated input level is -10dB. The
tip
of
JK
socket
is
used
for
Left
input
channel, and
the
ring of JK socket is used
for Right input channel, When you connect the socket’s tip
and ring, the right signal will be same as the left.

-10dB attenuation switch
Press this knob, the input signal will be attenuated 10dB, when the input signal level is
too strong.

BAL
：
This knob is used for controlling the stereo signal of the channel feed to L/R buses as
some proportion to balance the stereo sound image.

These 4

knobs are used for controlling the signal level feed to AUX1~4 bus, these 4 parts are all
EFF:
9
This knob is used for controlling the signal level feed to EFF bus, it has been set after
the channel fader, so it is enslaved to the fader position. Adjust these knobs when you
use effector on this channel.
11
CHANNEL FADER
:
This fader controls the output level feed to main bus from the input channel, adjusting the volume
balance between channels. Faders of channels not in use should be pulled down.
12
SIG,PEAK
Indicador
:
These two LED indicators detect the signal level which exists at the end of the
channel but in front of the channel fader. SIG LED flashing means the channel is in
normal, and PEAK LED will be light at 6dB before clipping to remind that the signal
level is too strong to the unit will be overload.
13
PFL
:
switch
This switch allows you to monitor the signal of the input channel, the signal is
sampled in front of the channel fader, so it has nothing to do with the fader position.
14
SUB,MAIN
channel output control
:
These two switches control if the channel signal will feed to the SUB and MAIN bus
or not separately. The switch should be turned off for unused channels.

GAIN control
Use this knob to adjust the level of the input signal to the optimal level. For the best
balance of S/N ratio and dynamic range, adjust this knob so that the peak indicator 12
lights occasionally.

P48V phantom power switch and indicator
This button switch is used for turning on or off the +48V phantom power in the unit. The +48V phantom
power will exist on the input socket of each microphone input channel when this switch is pressed.
Notices: Slide down all channel fader before turning on or off the switch;
Don't plug or unplug microphone after this switch were turned on;
Don't turn on the phantom switch when a dynamic microphone is in use.

This USB jack is a communication port by which the USB audio interface of the mixer can carry data
with a computer . The computer in use do not need any drive soft, plug and play, also it provides
power for the USB audio interface at the same time.
