CLIP-LED CHANNEL 1-16
Once the red Clip LED lights up, the corresponding channel is operating at the distortion limit. Adjust the Gain controller (N 18) so that the Clip LED
of the corresponding channel only lights up briefly when signal peaks occur. Avoid the permanent lighting of the Clip LED by reducing the input gain
or input sensitivity; if necessary, reduce the volume of an external audio device.
35
GR 1/2 CHANNEL 1-16
Press down on the GR 1/2 switch to add the corresponding channel to the channel group 1 (PAN all the way to the left), to the channel group 2 (PAN
all the way to the right), or to both groups of channel groups 1 and 2 in the same proportion (PAN in central position). The signals of the channels
grouped together in one group are routed simultaneously to the corresponding line outputs GROUP OUT 1/2. The total volume of the resulting group
is adjusted using the volume controller GROUP 1/2 (N 104); if the audio signals of the group are to be routed to the MAIN MIX sum channel, press
down on the L-R switch (N 105).
36
GR 3/4 CHANNEL 1-16
Press down on the GR 3/4 switch to add the corresponding channel to the channel group 3 (PAN all the way to the left), to the channel group 4 (PAN
all the way to the right), or to both groups of channel groups 3 and 4 in the same proportion (PAN in central position). The signals of the channels
grouped together in one group are routed simultaneously to the corresponding line outputs GROUP OUT 3/4. The total volume of the resulting group
is adjusted using the volume controller GROUP 3/4 (N 106); if the audio signals of the group are to be routed to the MAIN MIX sum channel, press
down on the L-R switch (N 107).
37
L-R CHANNEL 1-16
To route an input channel (channel 1 - 16) directly to the MAIN MIX sum channel, press down on the L-R switch of the corresponding channel.
38
PFL CHANNEL 1-16
Press down on the PFL switch (Pre Fader Listening) firstly, to be able to listen to the signal of the respective channel regardless of the channel level
controller (N 32) using headphones connected to the headphone jack PHONES (N 82),secondly, to make a more accurate gain adjustment since
the level of the input signal is now displayed on the 12-segment LED display of the MAIN MIX sum channel. At the same time, the PFL LED of the
corresponding channel and the PFL LED below the level display of the MAIN MIX sum channel light up. If the PFL switch is brought to its original
position, the PFL LED will go out.
