CONNECTIONS
Except for microphone and headphone outputs, all connections are cinch. Use good quality cinch-cinch
cables to prevent bad audio quality.
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 up to 2V. This includes
tuners, videos, CD-players, etc.
Both USB connections will be detected as a sound card on your computer. These connections are
bidirectional (play/record music simultaneously)

2. 2-BAND TONE CONTROL: The frequency of the DJ mic can be controlled over a +/-12dB range.
3. DJ MIC VOLUME: Used to adjust the level of the DJ mic.
4. MIC SWITCH: Used to switch the microphone:
 OFF
 ON
 TALK OVER: mic switched on; the sound level of all the other channels will decrease to
around -14dB

headphone output (15):
 Put the knob in the extreme left position to monitor a selected PFL signal (7).
