25-Seven Program Delay Manager
Version 2.3 Manual April 2013 11
Whichever method you choose, PDM tells you where you are in the exit process. The
LCD will look like this:
Exiting Speed:10“‘
Delay 3.4s Menu
When
Delay
equals 0 seconds, PDM exits Delay mode, feeding the input signal to its
output.
Operating Modes
A visual note …
PDM is an advanced time-manipulation tool for radio broadcasters. But since we can’t
play audio in this manual, we’ll use graphics to explain how PDM operates.
These drawings might also help you visualize what PDM is doing when you press its
buttons. The top line (pink background) shows what’s happening in the studio: this is
what’s heard by the talent and producer. The bottom line (blue background) shows the
resulting audio that PDM sends to the transmitter or network feed. The
white slash
through the blue line, beneath the
DUMP
button, shows where PDM has smoothly de-
leted material from the on-air program.
Build by Expanding, then Dump
Build
is the process of recording incoming audio to PDM’s delay memory, so there’s
enough built up to cover the gap during a Dump event. There are other ways to build
delay, shown on page 15.
After you press
EXIT
, press and hold down
COUGH
, and then wait. Watch the LCD screen. When it gets
close to
Delay 1.0s
, release
COUGH
and start talking again: PDM will smoothly transition to real-time
mode.
