OnAir 2000M2 Digital Mixing Console
7-8 Monitoring SW V 4.0 Date printed: 12.11.03
7.4 External PFL
The OnAir 2000M2 provides an external PFL audio input. If the EXT PFL
key is pressed, the key is illuminated, and the signal at the EXT PFL input
is routed to the PFL bus. A control output is activated if EXT PFL is ac-
tive. In addition, the EXT PFL function can be activated by a dedicated
control input on the “EXT PFL CTRL” connector (refer to chapter 15.13).
With this feature, the OnAir 2000M2 is well-suited for the integration with
a broadcast automation (CAB, computer-assisted broadcasting) system.
These systems need a separate PFL input that can be activated by the CAB
system itself.
