    The bottom line (blue background) shows the resulting audio that PDM sends to the transmitter or network feed. The white slash through the blue line, beneath the DUMP button, shows where PDM has smoothly deleted material from the on-air program.

  • Page 17: Cough Mode

    When COUGH is released, PDM starts rebuilding its delay. Another visual note… In this manual, we squeeze or stretch the type font a lot to illustrate how PDM adjusts audio speed. That’s because we wanted to make clear what’s happening.

  • Page 18: Exit Modes

    18 | OPERATING MODES Exit Modes PDM can handle the end of a delayed segment, before returning to real-time programming, by Rolling Out or Compressing. Instructions for setting the mode are on page Exit by Rolling Out This is the traditional method, similar to exiting an old-fashioned tape delay: n Talent finishes a sentence, presses EXIT, and stops speaking.

Whatever’s left in delay memory plays out slightly faster than normal. n Producer or network listens to PDM’s output. After talent’s final word, press BYPASS and go to the next program element.

    If the file isn’t the same length as the Delay Size, PDM will still join delayed audio when the file finishes. But it will subtly speed up or slow down the output as needed, to achieve the preset Delay.

    The BUILD, EXIT, COUGH, and DUMP buttons are discussed starting on page The BYPASS button is used for emergencies or when you want to take PDM out of the signal chain . It connects PDM’s analog and digital inputs to its outputs, with no processing or delay.
  • Page 24 As the peak input signal increases between -36 dBFS and Full Scale, successive LEDs light up. All four LEDs will light yellow if PDM is expecting a Livewire input but not seeing a valid signal. This is usually a configuration problem. All four LEDs will also light yellow in the unlikely event of internal error, even on XLR (analog and AES/EBU) systems.

    PDM. 20 PDM doesn’t receive e-mails; it only sends them. So it doesn’t need an incoming “POP” server. Also, PD-Alert does not support the SASL [Simple Authentication and Security Layer] protocol, so you won’t be able to use web mail services like Gmail.
  • Page 48 No matter which compression format you choose for e-mail audio files, PDM always keeps its internally stored files as full-resolution, uncompressed .WAV. 21 Assuming PDM is set for 8 second delay, 8 second dump increment, and 5 seconds each of before- and after-context.
  • Page 49 If you want to enter more than one “text-only” recipient, separate each address with a space. Retain dump files: PDM purges old audio files to make room for new files when space is needed in its internal storage. There’s a lot of storage, so dump files can hang around for a long time.

  • Page 62: Installation

    | 62 Installation PDM fits a standard 19” equipment rack, 1 unit high by 12” deep (allow additional depth for the connectors). While PDM doesn’t generate much heat, we recommend at least one unit of blank or perfo- rated rack panel separating it from any heat-generating devices above or below it. Do not block the fan or intake vents on the rear of the unit.
  • Page 63 Whenever there’s a valid digital input signal at 44.1 kHz or 48 kHz, PDM locks its internal sample clock to it. This assures high quality and full compatibility with other other equipment in the facility, so you can use PDM as an analog-to-digital bridge.
  • Page 64 64 | INSTALLATION n When PDM first powers up, it looks for a signal on its digital input jack. If it sees one at 48 kHz, it uses that sample rate to compute delay and ramping times. If it sees one at 44.1 kHz—or doesn’t see a valid digital signal at all—it uses 44.1 kHz.
  • Page 65 Typical PDM remote input (left) and output (right) circuits. Use the jumpers shown in gray for simple pushbutton / LED remote. Or use just the opto-isolator connections without pins 8 and 20 for interface to other equipment.
  • Page 66 Connecting to external logic or relay circuits: PDM’s GPIO inputs and outputs are isolated from its power supply and ground, and can be connected to external logic circuits or the power supplies in remote equipment: n Inputs require at least 6 mA flowing from the input common (pin 13) and the individual input circuit pin.
  • Page 67 If you want to control it from a computer or dumb terminal, you’ll need a DB-25 null mo- dem or a cable that reverses pins 2 and 3 (data), pins 4 and 5 (flow control). Since PDM uses standard pin configurations, you should be able to use an easily available DB-25 to DB-9 adapter to connect more common 9 pin cables.

  • Page 72 In5=None Out5=DumpReady You also have to configure the console itself, so messages are properly sent to PDM. You’ll need a computer connected to the Livewire network, and a browser. From the web browser, enter the IP address of this particular console. This will take you to the Element Control Center page.
  • Page 73 In our screen shot example, PDM’s Port Address 2 is set to communicate with port 4 of the GPIO Node at 192.168.1.21… In other words, if you pull Pin 11 (GPIO input 1) low on DB-15 number 4 (Port 4) on that node, PDM goes into Dump mode.

  • Page 74: Livewire Troubleshooting

    Once you’re sure audio is being sent to PDM, the unit will start in Real-Time Play mode. Now you should be able to monitor PDM at its Source address (as set in the Axia Source screen), from other devices on the Axia network. Verify meter and monitor levels to and from the PDM at your Livewire node or control surface.
