27. Crossfader. A high-grade dual rail 45mm fader determines the mix ratio
between the stereo signals routed to A (assigned to the left crossfader side)
and B (assigned to the right crossfader side). If no signals are assigned by
means of the switches (26), the crossfader is disabled.
28. Crossfader Curve switch. Allows the transition characteristic of the crossfader
between the A and B signal to be switches between smooth a flat and steep
mixing curve.
29. AUX Input for INPUT4. This is a 3.5mm Mini-TRS stereo socket which allows
to connect sources like MP3 players etc. without removing the mixer from its
mounting position.
30. POWER LED. Indicates whether the unit is switched on or off.
31. Output level meter. Displays the output level at outputs (4) and (5).
32. Main 1 level control. Determines the main output level present at outputs (4)
and (5).
33. Main 2 level control. Determines the output level present at output (9).
34. Talkover control. This control allows to set the amount of damping applied to
the stereo music signal when speaking into a microphone connected to either
the MIC1 or MIC2 input. The threshold level from which on this damping is
activated is set by the rear panel control (16).
35. PFL volume. Determines the signal volume at the headphone output (38).
Always set this control to minimum before putting on headphones, as sudden
high-volume impact may damage your ears. See further health advice below.
36. PFL Mix control. If the PFL mode (37) is set to “BLEND”, the headphone
signal can be a mix of the main output and the input(s) assigned to the PFL
bus by means of switches (25). This control determines the mix ratio between
the main and the PFL signal.
37. PFL Mode switch. This control offers two pre-listening modes: (A) Split. In this
mode, the master signal appears on one earcup of the headphones, the PFL
signal on the other earcup. (B) Blend. In this mode, main and PFL signal are
mixed with adjustable ratio by means of control (36). A LED indicates the
pressed position.
38. Headphones output. A ¼” TRS connector to connect a headphone. Turn the
PFL volume (35) down before plugging in any headphones.
