Summary of Contents for 25-Seven Systems program delay manager

  • Page 2 WARNING: : To reduce the risk of electrical shock, do not expose the chassis to rain or moisture. There are no user-serviceable parts in the Program Delay Manager. If repairs are necessary, contact Customer Service at 888-257-2578 (toll-free), or write to info@25-seven.com.

    For more Information Warranty Close-ups Some parts of this manual explain how Program Delay Manager works ““under the hood””. We’’ve set these in a san-serif face. You don’’t need to read these sections to operate or install the system…… but they’’re interesting, and understanding them will help you use the system better.

  • Page 4: About This Manual

    About this Manual These pages will help you get the most out of the Program Delay Manager™ (PDM). •• The first pages describe PDM’s basic concept and operation: if you’re looking at a unit that’s already installed in a rack, they may be all you need.
  • Page 5 You will need to give PDM a network connection and access to an e-mail system, since PD-Alert uses Internet e-mail. But it doesn’t need a separate computer to run: all necessary functions are built into PDM. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 6 •• Flexible remote control: Use GPIO (buttons, relay closures, or TTL), secure Web interface, RS-232, IP •• packets, or Axia/Livewire GPIO functions are fully assignable by the user. •• Requires Livewire version of PDM. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 7: Basic Operation

    PDM’s delayed output. Other installation possibilities are covered later in this manual. You can change which mode gets activated easily, at any time, from the front panel LCD or remotely from a Web browser. See page 22. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 8 For extra safety, you can also connect one of PDM’s GPIOs (page 27) 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. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 9 …press and hold the blue COUGH button. While you’re holding it down, PDM will con- tinue to send delayed audio to the transmitter. But it won’t store any new audio coming 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 10 . Some operators call this function roll out or wait and exit. Even if you’ve set the system to exit by speeding up, you can access this no-speed-change mode at any time: 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 11: Operating Modes

    After you press EXIT, press and hold down COUGH, and then wait. Watch the LCD screen. When it gets close to Delay 1.0s, release COUGH and start talking again: PDM will smoothly transition to real-time mode. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 12: Cough Mode

    (from before COUGH was pressed) still goes to the transmit- ter. The degree of slowdown, delay memory limit, and Dump seconds can all be set from the front panel. So can other important parameters. Instructions start on page 19. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 13: Exit Modes

    Exit by Compression You can use this mode to exit delayed mode without talent ever having to pause. •• Talent presses EXIT and keeps on talking. PDM keeps recording audio into memory. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 14 “over” might get passed to the transmitter. Pressing BYPASS instantly switches PDM’s output to real-time and erases PDM’s memory. That’s why you want to press it right after talent’s last word reaches the out- put. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 15: Alternate Build Modes

    •• 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 out- put as needed, to achieve the preset Delay. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 16: Delay And Speed Selections

    They also don’t rely on deleting pauses, so they can be used on audio with continuous energy, such as musical performances or background crowds at events. PDM’s algorithms excel at speech, and won’t destroy your talents’ delivery. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 17: Front Panel

    Occasionally, you may need to do software updates or other system-level maintenance (page 55). Put the unit in Bypass mode, or remove it from the signal chain, before beginning these operations. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 18: Detailed Operating Instructions

    After you turn off Bypass mode, the “ready” screen appears. This screen also appears after you exit a delay. You may also see a brief Waiting for audio stream message while PDM initializes its audio hard- ware. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 19: General Menu Procedures

    Any changes you just made in the menu system are cancelled, and PDM returns to its normal operating screen. Depending on which menu you’re in, you may need to press a few times to see the Confirmation  screen. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 21 In other words, the setting means a +14 dBu signal would read 0 dBFS—the maxi- mum allowable digital signal—and standard line level is 10 dB less than that, or –10 dBFS. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

  • Page 23 The factory default is 7, which takes about two minutes to fully build an eight-second delay. That’s sub- tle enough to be imperceptible to most listeners. There’s a discussion of Build Speed on page 8. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 24 Note: In previous PDM software, the System Menu also included RS-232 and External Clock Offset. These functions now appear only on the Web interface (page 35). Leaving the screen lit at all times can shorten the life of the LCD’s backlight. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
  • Page 25 We recommend you make these settings from PDM’s front panel, rather than using its GUI from a re- mote network computer, so you don’t accidently change something that’ll break the connection. Nu- meric IP addresses should be set only from the front panel. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...

    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. 25-Seven Program Delay Manager Version 2.3 Manual April 2013...
