5.3.4 Sum Pages
When touching Sum, the last used Master, AUX or N–X page opens for
parameter adjustment.
5.3.4.1 (Sum) Master Page
This page opens when selecting it from the Sum page. It allows parameter
adjustments for the two main master buses PRG A and Record. The master
bus labels may be renamed in the configuration tool.
Mono / Stereo The audio format for each main output bus (Mono/Stereo) is set to Stereo
by default but can also be set to Mono if required. In case of an AES/EBU
output, both channels then carry the left/right mono mix.
PFL PFL feeds the pre-fader audio signal to the PFL bus. This button enables/
disables the PFL (pre-fader listening) function on the corresponding main
master (highlighted if enabled). The “PFL Cut on Channel Active” (Broadcast
PFL Mode) has no effect on the audio signal.
Insert This button is visible only if an insert from the inserts pool is assigned to this
main master. It toggles the insert return on/off (highlighted if on).
(Master) Fader The fader value is indicated by the yellow-colored bar graph. The exact value
is displayed in dB and can be set with the rotary encoder below the field.
Notes: Any master output can be assigned to any physical fader on the desk; refer to
chapters 5.3.6 and 6.5.11.
The fader value adjusted with the rotary encoder (or the mouse) and the one
of the physical fader in the corresponding fader strip, if assigned, are work-
ing in parallel, it is a kind of “the last wins” circuit. This means that moving
the physical fader also effects the bar graph on the screen; the other way
round, however, a change with the rotary encoder or the mouse sets the fader
in take-over mode, because the new (electrical) fader value and the fader’s
(physical) position will then be different. If optional motor fader modules are
installed, the fader position of course follows the rotary setting.
The master outputs have a fixed output limiter; its parameters can be set in
the configuration tool.
