Consumption of this appliance, otherwise you could overload the wall outlet, which could cause fire.
8. Internal / External Voltage Selectors Internal of external voltage selector switches, if any, should only be reset
and re-equipped with a proper plug for alternative voltage by a qualified service technician . Do not attempt to alter
this yourself.
9. Object & Liquid Entry Take care to avoid any objects falling into or liquids are not spilled in to the inside of the

A: Channel section:
All channels of powered mixers & mixing consoles are the same.
(MONO CHANNEL)
(1)MICROPHONE
Electronically Microphone inputs accept a standard XLR male connector.
1.GROUND=shield, 2.HOT=signal input, 3.COLD=ground(shield).
You can use max -60dB~ -10dB according to signal level by GAIN control.
(2)LINE INPUT
Using by1/4"standard line connector, You can use unbalance(tip/signal) and
balance(tip/ring/signal). It can be connected with keyboards or other electric instruments.
Tip=positive ring=negative sleeve=ground.
(3)LOW CUT
This switch, when push, cut the input signal below 75Hz.
(4)GAIN CONTROL
Adjust input sensitivity from -60dB to -16dB with the MIC and -34dB to +10dB with the LINE.
(5)HIGH FREQUENCY EQUALIZATION CONTROL
Provides ±15dB of fixed frequency equalization that shelves at 12KHz.
(6) MIDRANGE GAIN CONTROL

(12).PAN CONTROL
The pan control sends continuously variable amounts of the post fader signal to either the
Left & Right main busses. In the center position, equal amounts of signal are sent to the and
right busses. As the control is roated in either direction, more signal is sent to the buss
indicated in the direction of the rotation while less signal is sent to the other buss, if the control
is turned all the way to one side, the signal is only.
(13) PRE-FADER LEVEL(PFL)
Pressing channel mode switch once disengages the stereo solo bus, and replaces it with a
separate mono PFL bus. PFL should always be used for gain setting.
