31. Input Gain control with level LED for input channels. Allows to compensate for different
source levels. A white signal LED indicated a signal present, a red Peak LED helps to adjust
sources to the same level while keeping required headroom. The Preak LED shall only
occasionally be lit.
32. Level control of input channels. Allows adjustement of the respective channel level.
33. PFL switch for input channels. Assigns the respective channel to the headphone bus for

zone output, depending on the setting of switch (39). Note that the level limitation applied by
means of the rear-side maximum level controls (6) / (11) is not displayed on the meter.
41. PFL level. Determines the signal volume at the headphone output (42). Always set this
control to minimum before putting on headphones, as sudden loud impact may damage your
