4) In each output channel, use the 3-way
equalizer (17) to attenuate or boost the
high frequencies (HIGH) and the low
frequencies (LOW) max . ±15 dB and the
mid-frequencies (MID) max . ±12 dB as
desired . The sound adjustments have an
effect on the level; therefore it may be
necessary to readjust the output volume
afterwards .
5) Use the corresponding control BAL (18)
to adjust the balance between the right
output and the left output for each output
channel . The adjustment does not have
any effect on the balance at the jacks
PHONES (4) and REC (28) .
6) Each output channel can be switched to
mono operation with the STEREO / MONO
selector switch (20) [button pressed] . The
signals of the left channel and the right
channel are mixed to a mono signal . Then
the mono signal can be picked up at both
jacks of the respective output . The volume
ratio between both jacks can still be ad-
justed via the control BAL (18) . The stereo
signal is maintained at the jacks for a re-
corder REC (28) .
5.3 Talkover
To improve the audibility of an announcement
while a music programme is played, switch on
the talkover function with the button TALK-
OVER (12) for the microphone on channel
MIC: If the button is pressed (LED above it
lights up), the levels of the input channels
CH 1 to CH 4 are automatically attenu-
ated to an adjustable extent via the control
T .O .ATTN . (7) . To switch off the function,
unlock the button .
Note: The level attenuation always has an effect
on both output channels, even if the microphone
channel MIC has not been assigned to both output
channels via the buttons Z 1 and Z 2 (14) . There is no
level attenuation at the recording outputs REC (28) .
5.4 Monitoring via headphones
The PFL function (prefader listening) allows to
monitor each of the input channels CH 1 to
CH 4 via headphones connected to the jack
PHONES (4), even if the corresponding fader
(15) is set to minimum . This will allow e . g .
to select the desired title on a CD or to time
the moment for fading in an audio source .
Alternatively, it is also possible to monitor
each output channel ahead of its fader (22) .
1) For prefader listening to an input channel,
press the button PFL (13) of the channel
(LED above it lights up) .
To monitor an output channel ahead of
its fader, press the button PFL (21) of the
channel (LED above it lights up) .
2) Adjust the desired headphone volume with
the control PHONES (3) .
