in at the input. Anything talent says will be heard only in the studio and control room,
and won’t go to air. When you let go of the
COUGH
button, PDM starts to rebuild the
delay.
The Cough function is usually used for short comments (and of course, coughs or
sneezes) that won’t last longer than the Dump Size. But it continues to protect your sig-
nal during longer comments: If you hold down the
COUGH
button for more seconds
than are stored in memory, PDM will mute the output. It will also flash the
COUGH
but-
ton to warn you of dead air.
…press the yellow
EXIT
button. PDM will stop storing new audio, and will send any ex-
isting audio in its memory to the transmitter. Then it will send incoming audio directly
to the transmitter in real-time.
Depending on how your system is set up:
••
PDM will play any remaining audio using time compression, subtly speeding
up what’s in memory to rejoin real-time faster; or
••
PDM will play what’s in memory with no speed change 1 . Some operators call
this function roll out or wait and exit .

Even if you’ve set the system to exit by speeding up, you can access this no-speed-change mode at any

Whenever you press the DUMP button, program audio gets dumped … as you’’d expect.
But PDM also does other things when you press that button:
a) PDM starts writing a pair of audio files, one of what was broadcast, and one ““off-air””
of what actually took place in the studio. You have indisputable records of both what
the listeners heard,
and
what they didn’’t hear because of the dump.
b) It then adds a few seconds of extra audio to these files, taken from before and after
the dump event. This makes it easier to identify the context.
c) PDM stamps the files with the current date and time, and stores them in non-volatile
memory.
d) It sends either the complete files, or text notes that they’’ve been created, to e-mail
addresses in your PD-Alert system. Setup instructions are on page 38.
