For stations serious about protecting their licenses and documenting their intent to keep the airwaves clean.
Leave it to 25-Seven Systems to re-invent the profanity delay. Program Delay Manager (PDM) brings the possibilities of the Internet age to “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.
The Air Check is in the E-mail
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 patent-pending PD Alert™ feature, a time-stamped audio file gets internally archived and emailed to the PD (or GM, or CE) every time questionable material is “dumped”. For stations serious about protecting their license, PD Alert provides an instant log record establishing your station’s action and intent to keep the airwaves clean.
Analogue/Digital and IP Audio
PDM is the only program delay to provide IP Audio and control over Axia Livewire audio networks. Whether you already have an IP audio system or you want to keep your plant IP-capable, PDM has you covered with future-proof Ethernet connectivity, as well as standard analogue and digital inputs and outputs.
Superior audio algorithm quality
25-Seven has a well deserved reputation for offering the industry’s most transparent time compression and expansion algorithms. Your listeners probably won’t appreciate our superior processing, because they won’t perceive it being used!
Superior control
Choices, choices! Easy to use front panel controls, GPIO and web interface each let you:
Build expands audio to build delay
Exit compresses audio to return to real time
Cough reduces delay to quickly exit, sneeze, or talk to the producer
Dump takes objectionable material off the air
You choose how to build / exit a delay
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.
Web-configurable
Say goodbye to hieroglyphs. Navigating though “set and forget” parameters is a breeze with the built in web interface. Configuration pages offer obvious control with all your settings on one simple screen, so you don’t waste time squinting at cryptic LEDs, or entering data though an ill-suited LCD interface. Talk to your PDM over your LAN or WAN. What could be easier?
Designed and built in the US
PDM was developed by an award winning, world-class team that has designed many great products for some of the biggest players in the broadcast business. All 25-Seven products are designed and built in the USA.
Controlling Program Delay Manager from a Web Browser
In addition to controlling Program Delay Manager using GPIO (contract closures), PDM comes with a built-in, password-protected web server, allowing you to remote control your unit across a local or wide area network. The server gives you five separate pages for complete and convenient control over your PDM.
Front Panel
An Adobe Flash-based application replicates PDM's front panel on your web browser, so every button and display is present and functions just like the real front panel. Through careful client-server communications management, round-trip latency is almost imperceptible, creating a seamless user experience. You can even control PDM from multiple computers. Just open a web browser interface on each, and anything you do on one computer will be reflected on the others, as well as on PDM's physical front panel.
Configuration
Tired of learning hieroglyphics just to configure a profanity delay? Navigating though “set and forget” parameters is a breeze with the PDM's Configuration page. You'll find obvious control with all your settings on one simple screen, so you don’t waste time entering data though an ill-suited LCD interface.
PD Alerts™
A dedicated page lists all of the PD Alert emails the PDM has sent to your chosen staff.
Dump Archive
A Dump Archive shows all your saved dumped audio files. Easily review just what's been cut out of your air stream.
Insert Files
Easy management of the files you can use for quickly building your buffer at the beginning of the show. No more flash drives and cryptic file names!
Program Delay Manager technical details and specifications
Power Input
PDM comes with a standard IEC C14 power connector.
Network
PDM connects to a standard 10/100Base-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.
Analogue 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 analogue 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 analogue 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 Ouputs
On the Livewire version of PDM, audio connections are exclusively via the network. PDM-Axia also supports Livewire-based GPIO.
GPIO
Eight parallel control inputs and eight parallel control outputs appear on a DB-25 connector. Input and output functions are assigned through a configuration menu on the front panel. Inputs and outputs are opto-isolated for easy interface to other equipment. A +5v supply and ground are also brought out to the DB-25 for simple remote controls using pushbuttons and LED status readouts. The +5v supply can carry 200 mA, more than adequate for 8 LEDs and 8 logic inputs. It is protected by an internal, self-resetting thermal circuit breaker.
