FRONT PANEL DESCRIPTIONS
1. MIC Use this balanced XLR jack to connect a microphone to the machine.
The phantom power required for condenser Mics can be activated with switch PHANTOM
2. Channels 1 feature an additional LINE / input on a balanced 1/4” jack.
3. Use the GAIN control to adjust the input gain. This control should always be turned fully counter clock
whenever you connect or disconnect a signal source to one of the inputs.
4. In addition, the mono channels are equipped with a steep LOW CUT filter (slope at 18 dB/oct, -3 dB
at 75 Hz) designed to eliminate unwanted low-frequency signal components.
5. 6. 7. The upper (HIGH) and the lower band (LOW) are shelving filters that increase or decrease all
frequencies above or below their cut-off frequency. The cut-off frequencies of the upper and lower band
are 12 kHz and 80 Hz respectively. The MID band Is configured as a peak filter with a center Frequency
of 2.5 kHz
8. The PK LED’s of the mono channels illuminate when the input signal is driven too high, which could
cause distortion. If this happens, use the GAIN control to reduce the preamp level until the LED does not
light anymore.
9. EFF sends enable you to feed signals via a variable control from one or more channels and sum these
signals to a bus. The bus appears at the console’s FX sent output and can be fed from there to an ex-
ternal effects device. The return from the effects unit is then brought back into the console on the stereo
channels. Each FX send is mono and features up to +10 dB gain.
10. The PAN control determines the position of the channel signal within the stereo image. This control
features a constant-power characteristic, which means the signal is always maintained at a constant
Level, irrespective of position in the stereo panorama.
11. The LEVEL control determines the level of the channel signal in the main mix.
12. LINE IN Each stereo channel has two balanced line level inputs on 1/4” jacks for left (L/MONO) and
right (R) channels. If you use only the (L/MONO) jack, same sound is output from both Left and right
speakers.
13. The EFF SEND connector outputs the signal you picked up from the individual channels using the
EFF SEND controls. You can connect this to the input of an external effects device to process the EFF
bus’s master signal. Once an effects mix is created, the processed signal can then be routed from the
effects device outputs back into a stereo input.

14. PHONES/CTRL ROOM OUT
The stereo PHONES connector (at the top of the connector panel) is where headphones are connected.
The unbalanced CTRL ROOM OUT connectors carry the summed effects and main mix signals as well
as soloed channel signals. The PHONES/CONTROL ROOM control in the main section adjusts the level
Of both headphones and main monitor outputs.
15. The unbalanced CTRL ROOM OUT jacks carry the summed effects and main mix signals, as well as
all channel signals. The PHONES/CTRL RM control adjusts the level of both headphones and main
16. USB Jack
play/pause switch. Long press this key until the indicator flashes. Then turn on the phone Bluetooth,
search until the phone shows the Bluetooth link of the mixer, join the link until the connection is success-
ful.
Vol+/Next Press once to key is play song skip to next song. Press and hold it volume up.
Vol-/Prev Press once to key is play song skip to previous song. Press and hold it volume down.
17. The -10d8 switch which selects between +4 dBu and -10 dBV. At -10 dBV (home-recording level),
the input is more sensitive (requires less level to drive it) than at +4 dBu (studio level).
18. REC OUT These connectors are wired in parallel with the MAIN OUT and carry the main mix signal
(unbalanced). Connect the 2-TRACK OUTPUT to the inputs of your recording device. The output level is
adjusted via the high-precision MAIN MIX fader or rotary control.
19. 2TK RET The 2-TRACK INPUTS are used to bring an external signal source (e.g. CD player,tape
deck, Etc.) into the console.
20. 21. The MAIN OUT connectors are unbalanced and balanced jacks. The main mix signal appears
here at a Level of O dBu. The MAIN MIX fader adjusts the volume of these outputs.
22. The red +4BV LED lights up when phantom power is on. The PHANTOM switch activates the phan-
tom power supply on the XLR connectors of all mono channels.
23. EFF SELECT - Selects the internal effects processor will apply to the various channels. Each channel
can send different levels of audio to the processor by adjusting their EFF SEND knobs. See the EFFECTS
section for an explanation of the available effects.
24. Level indicator The high-precision 4-segment display accurately displays the relevant signal level.
25. The EFF SEND control adjusts the volume level of the EFF signal provided at connector EFF SEND
JACK.
26. The EFF TO MAIN control feeds the effects signal into the main mix. If the control is turned all the
way counterclockwise, no effects signal is present in the sum signal of the mixing console.

27. When the 2TK TO MIX switch is depressed, the 2-track input is assigned to the main mix providing
an additional input for tape machines, MIDI instruments or other signal sources that do not require any
Processing.
28. Press the 2TK TO CTRL RM switch if you want to monitor the 2-track input via the CTRL ROOM
OUT. This provides an easy way to monitor signals coming back from tape to ensure that they are re-
cording correctly.
29. If you want to monitor only the effects signal in your headphones or monitor speaker(s), press the
EFF TO CTRL switch. Now the signal of the effects processor can be monitored alone, and the main mix
and/or CD/tape signal is no longer present on the phone and control room outputs.
30. Use the MAIN fader to set the overall volume level of your machine.
31. The PHONES/CTRL RM control adjusts the level of both headphones and CTRL ROOM outputs.
