2.1.FOR SAFE AND EFFICIENT OPERATION
Be careful with heat and extreme temperature
Avoid exposing it to direct rays of the sun or near a heating appliance.
Not put it in a temperature bellow 41°F /5°C, or exceeding 95°F /35°C.
To avoid placing on un-stable location
Select a level and stable location to avoid vibration.

4 / 15
Do not use chemicals or volatile liquids for cleaning
Use a clean dry cloth to wipe off the dust, or a wet soft cloth for stubborn dirt. Pull the plug before
cleaning.
If out of work, contact sales agency immediately
Any troubles arose, remove the power plug soon, and contact with an engineer for repairing, do not
open the cabinet by yourself, it might result a danger of electric shock.
Take care with the power cable
Never pull the power cable to remove the plug from the receptacle, be sure to hold the plug. When not
using the device for an extended period of time, be sure to disconnect the plug from the receptacle.
Transport
The console should be transported either free-standing or in an appropriate case. The console should
be protected during transport with foam or similar shock-absorbing materials. So you can avoid
damages.
Hearing
To avoid hearing damages, you should not operate a sound system with high levels. This applies to
monitor systems, which are in the near of the ear, headphones or IEMs also.
Important
Damages caused by the disregard of this user manual are not subject to warranty. The dealer will not
accept liability for any resulting defects or problems. Make sure the electrical connection is carried out
by qualified personnel. All electrical and mechanical connections have to be carried out according to
the European safety standards.

3. Mono input channel
1. Balance input (MIC)
Electronically balanced inputs accept a standard XLR male connector.
2. LINE-input
The unbalanced LINE input is provided for the use of an unbalanced
mic or to accept an unbalanced high impedance input signal (e.g. Deck,
turntable, keyboards…)
3. GAIN
With this button you can adjust the input sensitivity of each channel.
4. PK
This LED will light when the signal level approaches clipping at any of
the three monitored points: pre-EQ, post-EQ or post-fade
5. -20dB
If this switch is pressed the input signal will be lowered by 20dB.
6. Equalizer
HIGH: With this control you can raise or lower the highs. At the
beginning the control has to be set on 12 o’clock position. Clockwise
turning raises the highs, counterclockwise turning lowers the highs.
MID: It is a bell shaped filter; with it you can raise or lower the signal by
15dB around the center frequency. The center frequency can be set
between 249Hz and 6 kHz. Q = 1.
LOW: With this control you can raise or lower the lows. At the beginning
the control has to be set on 12 o’clock position. Clockwise turning
raises the lows, counterclockwise turning lowers the lows.

7. AUX 1/AUX 2 FX
The AUX are pre-fader and post-EQ. Normally they are used for
foldback or monitor speakers, which need to be controlled separately
from the main P.A.
8. PAN
With this control you can change the distribution of volume on the
channel R and L or the groups 1 and 2. If the control is set on the
middle position, both sides get the same signal portion. Turning
clockwise raises the signal portion of channel R or group 1,
counterclockwise for L or group 2.
9. MUTE
Press this switch to turn the channel signal off. The large red LED lights
if is muted.
10. MAIN
This is the main control switch. If this switch is not pressed there is no
output.
11. SUB
The main group control switch. If this switch is not pressed there is no
output.
12. PFL
You can monitor only the signal of this channel on your headphones by
pressing PFL.
13. Channel fader
With it you can control the volume of the channel.

4. Stereo outputs
1. MIX OUT
The mix left and right outputs are sent from the XLR sockets as
balanced signals.
2. SUB
The SUB output jack.
3. AUX OUT
AUX 1: This is an impedance balanced phone-jack type output. This jack
outputs the signals from AUX (AUX1) bus. You can use this jack, for
example, to connect an effect unit, cue box, or other monitoring system.
AUX 2: This is an impedance balanced phone-jack type output that outputs the signals from
AUX2 bus. You can use this jack, for example, to connect an effect unit.
Note: The channel fader can adjust the level.
4. AUX RET: MONO L/R
These are unbalanced phone-jack type line inputs. The signal received by these jacks is sent
to the MIX L/R buses and the AUX 1 (AUX 2) bus. These jacks are typically used to receive
the signal returned from an external effect device (reverb, delay, etc.)
Note: These jacks can also be used as an auxiliary stereo input. If you connect the L (MONO)
jack only, the mixer recognize the signal as monaural and will send the identical signal to the L
and R jacks.
5. PHONE
This is used for monitoring the master signal and individually monitoring each channel with
PFL.
6. MIX BALANCE OUT
Left/Right master out balanced interface.
7. 2TK IN
These two RCA phone sockets are unbalanced left and right line-level
inputs, used for connecting a playback device.
8. REC OUT
These two RCA outputs carry a copy of the MIX L and MIX R signals.
Here you can connect a recording device.

5. Master
1. DIGITAL EFFECT DISPLAY
2. PHONE
This is used for monitoring the master signal and
individually monitoring each channel with PFL,
L/R 6 G1/G2.
3. PARAMETER
With this control you can adjust the effect
parameter such as depth, speed and so on. All
the parametric levels will being resetting
4. AUX 1
This is used for adjusting the built-in effect level
send to AUX bus.
Note: The built-in effect level which is sent to
AUX bus is not controlled by EFFECT fader.
5. SEND
This is used for adjusting the volume of AUX 1.
6. AUX 2 FX
This is used for adjusting the volume of AUX 2.
7. EFFECT Fader
This fader is used for adjusting the effect output level of built-in/external effect units for each channel.
8. AUX RET
This is used for adjusting volume of AUX sound, when sending AUX signal to used jack.
9. POWER LED & Level meters
POWER: This LED lights when the mixer is on.
PFL: This LED lights when the PFL is activated.
+48V: This LED light, when the phantom power for each mono cannel is activated.
10 segment LED level meters: The level of the output is displayed on the 10 segment level meters. If
level shows PEAK, please lower the output level.

If the switch is pressed the signal of the SUB is
send to 2TK/MP3, if it is not pressed it gets the
signal from the MIX.
12. /13. TO L/R
These are two select switches for the group
signal send to the MIX or SUB output. When
they are pressed, the group signal is send to
MIX output.
