PDM Operator's Manual Version 2.4a • September 2019
Program Delay Manager at a Glance
Broadcasters have been using Profanity Delay for decades. The first schemes used analog
tape loops, and delayed programming by several seconds. Operators who heard something
inappropriate switched the audio feed to real-time, stopping those last few seconds from
getting to the transmitter (and presumably, keeping listeners and the FCC happy).
Before the next program segment, the operator would play a jingle or promo to the trans-
mitter, while the host talked into the tape delay. This would build up a fresh delay for the
next obscenity.
Tape delays were soon replaced by trouble-free digital ones, and many of today’s units can
slow down the input signal to build a delay without interrupting programming. Other
features may include automatic playout of filler material, a ‘cough button’ to let hosts
speak privately to a producer while delayed audio is on the air, and a smooth ramp back to
real-time when desired.
25-Seven’s Program Delay Manager combines the functions of the best delay units with
some unique and potentially vital features:
Automatic audio logging of every “Dump” event:
n
What gets fed to the transmitter is automatically recorded on a time-stamped audio
file. There’s no question of what actually went on-air.
n
What got dumped is also automatically recorded, on a time-stamped “off-air” audio
file. There can’t be any question of what actually took place in the studio or over your
phone lines.
n
On-air log files provide proof of standards for regulatory authorities. You can
instantly demonstrate what people actually heard, not what they thought they heard.
n
Off-air audio files provide proof of fairness for listeners. If you had to dump a guest
comment, you can demonstrate exactly what was considered objectionable.
n
Off-air audio files can also be used as extended content for less restrictive
environments. Create Web promos, or let Internet listeners hear highlights of ‘what
couldn’t go on the air!’.
n
Log files provide a valuable record for program management and personnel
development or evaluation.
n
All log files include short audio segments from before and after the event, so you can
identify their context.
