Inputs
7 Specifications
1) Advance the master faders until the mixing ratio of
the audio sources connected can be adjusted to an
optimum level.
2) Use the channel faders to adjust the desired volume
ratio of the audio sources: Adjust the audio sources
to be heard at the highest volume to an optimum lev-
el ( see chapter 6.1 ); reduce the levels of the other
audio sources accordingly.
With an additional audio source connected to the
input ‘AUX-IN’ or ‘PLAYBACK’, mix the signal of this
audio source to the master signal with the level con-
trol ‘AUX-IN’ or ‘PLAYBACK LEVEL’.
3) To indicate the master level by means of the peak
program meter, none of the PFL buttons must be
pressed.
4) Use the master faders to adjust the final level of the
stereo master signal available at the master output
‘MAIN MIX OUTPUT’. Adjust the level for the signal
at the recording output ‘RECORD’ with the control
‘RECORD LEVEL’ ( the signal for the output ‘record’
is taken after the master faders ).
Usually an optimum level control is obtained when
the peak program meter shows values in the 0 dB
range (indication 0 dB = 1.23 V) with music passages
of average volume. However, if the output level is too
high or too low for the following unit, the level of the
master signal must be increased or decreased accor-
dingly.
6.4 Monitoring via headphones
Via stereo headphones connected to the jack, the mast-
er signal or one or several input channels can be monit-
ored (pfl=pre-fader listening). In this case, the peak pro-
gram meter will always indicate the signal to be heard
via the headphones.
1) For post-fader monitoring of the master signal, unlock
all PFL buttons.
2) For simultaneous pre-fader monitoring of one or sev-
eral input channels, press the corresponding PFL bu-
tton(s). Due to technical reasons, the signal is mono-
phonic only.
3) Adjust the headphone volume with the control
‘PHONES’.
