16 25-Seven Program Delay Manager
Version 2.3 Manual April 2013
Build with PreRoll
You may want to build your delay without changing speed or playing an insert file. Pre-
Roll Mode lets talent start their introduction
before
the scheduled program time. This is
often done by studios feeding a network, rather than a local transmitter.
•
Set
Build Mode
to
PreRoll
. Then, you can press
BUILD
and have talent start
talking
earlier
than the program is supposed to air. This early start, heard in
the studio only, should be the same number of seconds before airtime as
you’ve chosen for
Delay Size
.
For example, if you feed network at Noon and use a 10 second delay, you would back-
time and start the PreRoll ten seconds before noon. In other words, talent starts talking
at 11:59:50; PDM then outputs the material starting at exactly 12:00:00.
•
The LCD will start to count up with numbers and a bar graph, like this:
Building Speed:10 “‘
Target Delay: 10.0 {}
Delay 3.4s Menu
While PDM is counting, studio audio is sent to PDM’s delay memory, and its output is
muted.
When the full delay time is reached (and the solid bar fills the screen), PDM starts play-
ing delayed audio to the air chain. If you started the PreRoll at the right time, this
should be exactly the right time to start sending the program to the network.
Delay times, time manipulation, and speed selections
PDM uses advanced time manipulation algorithms that don’t affect pitch and don’t add
harmonic distortion or frequency limitations. They also don’t rely on deleting pauses,
so they can be used on audio with continuous energy, such as musical performances or
background crowds at events. PDM’s algorithms excel at speech, and won’t destroy
your talents’ delivery.
