Program Delay Manager

From: Telos

-PD Alert™ instantly emails time-stamped audio files whenever Dump is pressed
-Files capture what took place both on- and off-air
-Seamlessly builds and exits delay
-Configurable delay time, build and dump options

Leave it to 25-Seven® Systems to re-invent the profanity delay. Program Delay Manager (PDM) brings the possibilities of the Internet age to a “stand-alone box” technology that hasn’t advanced much since the 1980’s. Ease of use, transparent audio quality and program director friendly features converge in PDM to take an old process to a new level.

Program Directors have more on their plates today than ever before. There’s no way anyone can monitor every broadcast hour of every day, but PDs need to be the first to know what happened when that “dump” button got pressed.

With Program Delay Manager’s patented PD-Alert™ feature, two time-stamped audio files capturing what took place both on air and off air get internally archived and emailed to the PD (or GM, or CE, or the legal team) every time questionable material is “dumped”. 

For stations serious about protecting their license, PDM provides an instant log record establishing your station’s action and intent to keep the airwaves clean.

PDM comes standard with 99 seconds of stereo audio delay, and a dump button that can be set to remove any number of seconds you choose.

Build a delay through pre-rolling, time expansion or audio file play-out capabilities built right into PDM. Exit a delay through time compression or use the Cough button to simply wait and exit.

Dump audio through the standard “cut and rebuild” method, or use PDM’s Overkill™ feature to play a “fill” file. Overkill allows you to select a show specific file from a list and play it over the dump buffer instead of collapsing the delay.


-Power Input:
PDM comes with a standard IEC C14 power connector.


PDM connects to a standard 100BASE-T network connection. This port is used for Axia Livewire, synchronization to a network time server, and secure remote control via a web browser. If connected to the Internet, it should be behind a hardware firewall.


-Analog Inputs and Outputs:
Stereo inputs are electronically balanced XLR females, pin 2 hot, with a load of 20kΩ: this makes it compatible with all modern electronically-balanced outputs. If fed from a transformer-balanced output, we recommend bridging a 680Ω resistor between pins 2 and 3. Outputs are electronically balanced XLR males, pin 2 hot, designed to feed a load of 600Ω or greater. Input and output sensitivity default levels can be set from the front panel, and can range between +20dBu and -10dBu.

-Digital Inputs and Outputs:
When set to AES/EBU via the configuration menu, this input conforms to IEC 958 Professional (5v p-p,
110Ω balanced) on XLR connectors. When set to s/pdif, the voltage and impedance switches to IEC 958
Consumer (.5v p-p, 75Ω unbalanced): connect signal to pin 2 and shield to pins 1 and 3. Digital output (selectable AES or s/pdif) is always active, regardless of whether you are using analog or digital inputs. PDM will lock to any valid 32 kHz, 44.1 kHz, or 48 kHz signal at the digital input connector, even if you have selected analog for the input. In that case, the digital input controls PDM’s internal sample rate. If PDM is not connected to a digital input, it uses its own high-reliability 44.1 kHz sample clock


-Axia Livewire Version Inputs and Outputs:
On the Livewire version of PDM, audio connections are exclusively via the network. PDM-Axia also supports Livewire-based GPIO.
