25-Seven PDM: ‘It Just Works’
PHOENIX — KTAR(AM/FM)’s
engineering department had one of those visits, from Rick Sawyer from 25-Seven
were shown a box that, like most of these demonstrations, would solve all the
world’s problems. It was the 25-Seven Precision Delay. This box was touted as
the solution for HD diversity delay and smooth transition in and out of delay
for sports programs, etc.
It was also promoted as a precise delay for
FM booster synchronization and large delays such as time zone shifts. We did
not need any of that.
We were, however,
in the market for a profanity delay system that would stay in AES sync on the
incoming AES input, provide simple front-panel control, allow engineer-selectable
access to controls, easy remote control and provide precise time delay in order
to function as both a profanity delay and an audio sync to TV during simulcast baseball
profanity delay was notorious for losing AES sync; and its front-panel controls
allowed the user to switch the input from digital to analog accidently and not
be aware of what he had done.
we had an elaborate set of remote controls for the existing profanity delay
tied into our Harris RMX digital consoles and the host turrets, we were not
easy to convince that the 25-Seven Systems Program Delay Manager could do the
job. After all, we’d had to design and build outboard power supplies and relay
systems to make the existing system work and get the Harris remote panels to
light up properly. On top of that, the 25-Seven PDM was not able to provide the
precise time increments we needed for synching up to the TV audio.
Rick told us
that we would need the 25-Seven Systems Precision Delay along with the PDM to
do what we wanted. No deal! But the day after our visit, I got the following
email from Rick:
First, let me thank you for the warm Phoenix hospitality
and the station tour. I appreciate it! You certainly have a gorgeous
facility and it is nice to see one so well designed.
Second, a 25-Seven PDM is departing our California
facility today headed your way. Two things to note about this unit:
(1) You WILL be able to set delay in tenth-second
increments using either the menu settings on the front panel or the
configuration page on the web interface. From FP, select MENU, CONTROLS,
DELAY SIZE. This should address your sports broadcast synchronization
(2) All audio settings are in a category of their
own: MENU, AUDIO. This should dramatically reduce the likelihood of someone
inadvertently changing inputs/outputs when resetting delay increments.
And remember, since PDM can be completely controlled
via its browser interface, it should be easy for your sports guys to adjust the
delay while watching/listening to TV from a non-studio location.
This is a factory new unit (not a demonstrator),
so if it meets your needs, which I am confident it will do, you can just let
BGS know you are keeping it and work directly with them on the purchase without
our having to swap machines.
forward to hearing from you after your “test drive” and, as always, I am
available to assist in any way.
the 25-Seven PDM in hand, it took only an hour with the fully programmable
remote control relays and inputs to interface to our Harris controls. The
internal power supplies in the PDM were more than adequate to light the Harris
controls. We have not experienced any AES synchronization issues. The front-panel
controls are easy to use and the operators can tell at a glance the status of
feature of the 25-Seven is the ability of the box to send an email whenever the
dump button is pressed. The email includes the dumped audio file. This is
particularly useful to our programming department, since most of the bleeps are
necessitated by our own on-air talent.
Program Delay Manager is a feature-rich box that is easy to program and easy to
use. It just works.
