CLEANING THE MIXER:
Clean by wiping with a polished cloth slightly dipped with water. Avoid getting water inside
the unit. Do not use volatile liquids such as benzene or thinner which will damage the unit.
CONNECTIONS
Except for microphone and headphone, all connections are cinch. Use good quality cinch-
cinch cables to prevent bad audio quality. (example: JB Systems code: 2-0370)
For more information on connections, please refer to the next chapter.
Be sure to turn off the mixer before you make changes to the different connections.
In this manual we talk about "line inputs". This is a global name for inputs with a level
between 750mV and 2V. This includes tuners, videos, CD-players, etc.

CONTROLS AND FUNCTIONS

1. DJ MIC INPUT JACK: Accepts an unbalanced microphone ¼" mono jack. 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 or line/aux.
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. 2-BAND TONE CONTROLS: The frequency of each channel can be controlled
separately over a range from -26dB to +12dB. In the center position the tone control is
flat. (switched off)
5. TALKOVER: Use this switch to automatically mute the input channels 1 and 2 while
you are talking through the DJ microphone.
6. PFL SELECTOR: Used to select the source you want to monitor. You can listen to any
input channel while its channel fader is closed.

7. CHANNEL FADER: Used to set the level of each channel separately.
8. CROSSFADER: With this fader you can mix over between the channels 1 and 2. The
crossfader only works when you move the selected channel faders (7) to the desired
level!
9. VU METERS: Monitors the output level of master 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.
10. POWER switch: Used to turn the power of the mixer on and off. The blue led is lit
when the mixer is turned on.
11. MASTER LEVEL: Used to adjust the level of the Master output.
12. MIC LEVEL: Used to set the level of the DJ micro input.
13. CUE LEVEL: Used to control the output level of the headphone output.
14. HEADPHONE jack: You can monitor all inputs/outputs when you connect any modern
stereo headphone to this 6.3mm jack.

15. MAINS AC ADAPTER: connect this adapter to a 230V/50Hz mains outlet. Plug the
small connector of the adapter in the adapter input (16)
16. ADAPTER INPUT: connect the supplied AC adapter to this input. If you should use
another adapter, please make sure that it has 12Vac and minimum 500mA.
17. RECORD OUTPUT: Used to connect any recording equipment to the mixer. This
output is not influenced by the master volume.
18. MASTER OUTPUT: Used to connect an amplifier. The output level can be set by the
master volume.
19. INPUT CHANNELS: each used to connect two different audio signals. Refer to
switches (2) to change one line input to phono level. The input source selector on the
front determines which input will be active.
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.
