PDM Operator's Manual Version 2.4a • September 2019
You can choose how long PDM takes to build a delay. Choose a setting based on how quickly
your talent talks, how subtle you want the time manipulations to be (slower speaking styles
can work with higher speed settings), and how long you’re willing to wait for the delay
memory to fill.
As a general guide:

To dump an objectionable comment…
…tap the red
DUMP
button. PDM will eliminate the last few seconds of audio that you
heard in the control room, before it can get to the transmitter or network feed. How many
seconds get dumped depends on how PDM is set up, and on how much delay memory it’s
had a chance to store.
n
The size of each Dump event is determined when the unit is set up, but can be
changed at any time—even while you’re on the air.
n
When there’s enough audio in memory to smoothly Dump the full amount you’ve
preset, the
DUMP
button will light
7
. This starts a few seconds after you begin a
segment, or as you rebuild after an earlier Dump event.
n
You can also press
DUMP
when it’s not lit: PDM won’t have enough audio stored to
Dump all the seconds you’ve designated for a dump event, but it will dump whatever
it has available.
n
As long as the
DUMP
button is held down, incoming audio will be discarded.
After a Dump event, PDM begins to rebuild its memory with incoming audio, using subtle
time expansion so programming is never disrupted.
7 For extra safety, you can also connect one of PDM’s GPIOs (page 34) to keep your phone system off-air until
enough delay has been built for a smooth Dump, or to light a “delay unsafe” warning for producers.
