CONTROLS AND FUNCTIONS

1. DJ MIC INPUT JACK: Accepts an unbalanced microphone with XLR connector. You
can find the ¼" mono jack on the rear of the mixer. This input is mainly used as DJ-
microphone. The talkover does not affect the signal level of this input.
2. INPUT SOURCE SELECTOR: Used to select the correct input on each channel:
Phono, line, aux or mic. On some channels there are additional input selectors on the
back.
Hint: Line, Aux, CD, Tuner, etc... are different names for inputs with almost the same signal levels.
3. GAIN LEVEL: Adjusts the input level on each channel. Use this control to adjust the
level on the VU-meter at about 0dB.
4. 3-BAND TONE CONTROLS: The frequency of each channel can be controlled
separately over a range from -26dB to +10dB. In the center position the tone control is
flat. (switched off)
5. TALKOVER: Use this switch to automatically mute the input channels 2 and 3 while
you are talking through the DJ microphone.
6. PFL SELECTOR: Used to select this channel to be monitored via the headphones
output. Pressing multiple Cue-buttons makes it possible to derive a mixed sound from
the selected sources.
7. CHANNEL FADER: Used to set the level of each channel separately.
8. BEAT LEDS: These leds switch on and off to the rhythm of the beat. These leds help
you to find the right cadence.
9. CROSSFADER: With this fader you can mix over between the channels 2 and 3. The
crossfader only works when you move the selected channel faders (7) to the desired
level!
10. VU METER SWITCH: Used to select the input of the LED VU meter: Master output
(stereo) or PFL (CH2 and CH3, each on 1 led bar)

11. VU METERS: Monitors the output level of master1 or PFL. Make sure the levels do
not exceed 0dB (or 100%). The audio risks to be distorted when the signal level
comes in the red zone of the VU-meter.
12. POWER switch: Used to turn the power of the mixer on and off. The blue led is lit
when the mixer is turned on.
13. MASTER2 LEVEL: Used to adjust the level of the Master2 output.
14. BALANCE MASTER1: used to adjust the balance between left and right output on
Master1.
15. MASTER1 LEVEL: Used to adjust the level of the Master1 output.
16. CUE LEVEL: Used to control the output level of the headphone output.
17. CUE MIX: With this fader you can mix the master output and any of the input channels
through the headphone output:
• Put the fader in the extreme left position to monitor a selected PFL signal.
• Put the fader in the extreme right position to hear the master output.
• Put the fader in any other position to hear a mix of the two signals.
This option makes it possible to check your mix before you put it on the master output.
18. HEADPHONE jack: You can monitor all inputs/outputs when you connect any modern
stereo headphone to this 6.3mm jack.

19. MAINS CABLE: connect this cable to a 230V/50Hz mains outlet. Before use, inspect
the cable to be sure it's not damaged!
20. GROUND (GND) CONNECTION: Many Turntables have a GND-connection. It is
preferable to connect this signal ground to the GND-connector. If your turntable does
not have a ground wire, you don't have to use this connector.
21. MASTER OUTPUTS: These outputs carry the same signal but can be controlled
independently by the master1/2 levels. Use the outputs to connect unbalanced
amplifiers.
22. RECORD OUTPUT: Carries the same signal as the master outputs but is not
influenced by the master level, balance and mono/stereo controls. Used to connect
analog recording equipment.
23. INPUT CHANNELS: each used to connect two different audio signals. Refer to
switches (24) to change one line input to phono level. The input source selector on the
front determines which input will be active.
24. PHONO/CD SWITCH: This switch makes it possible to switch between the CD and
phono level inputs.
25. LINE INPUT CHANNEL1: used to connect a line level audio signal to channel1.
26. MIC INPUT: ¼" mono jack alternative to the XLR microphone input on the front (1).
