Digital Broadcast Delay

• Seamless Delay update – No clicks, pitch changes and or other unwanted artifacts Digital I/O's: AES/EBU, S/PDIF, Wordclock BNC 75ohm
• 5200 ms Delay per channel
• Analog 24 bit A/D-D/A converters
• True 24 bit delay resolution
• Sample rates:  Internal 44.1, 48kHz - External 32, 44.1, 48kHz
• Sample Rate Conversion from 31-49kHz
• Total Recall via programmable setups
• Tap Delay time – Instant or Preview
• Delay time in: Frames (Various resolutions), Sub-frames, Fields, Milliseconds and Sub-Milliseconds (0.1 ms increments)
• Separate Dial and Nudge for Delay time adjustment
• Independent Dial/Nudge resolution
• Built-in digital Output Fader (remote controllable)
• Remote capabilities: RS-485 (Input only) for Recall Setup, Delay time adjustment & GPI for external control of the digital Output Fader or Tapped Delay time
• User Interface Lock mode for "Set & Forget" purposes

Unique User-Interface
The resolution of the delay can be displayed in frames, sub-frames as well as milliseconds and sub-milliseconds (0.1 ms increments), allocated individually to each of the two delay time controls. The Tap control features a Preview as well as an Instant mode. The Preview Tap enables preview of the tapped delay time before it is inserted in the actual Audio chain, while the Instant Tap inserts the tapped delay time immediately. The User Interface also has a "Set and Forget" lock function, for when the D22 is being used in a more "fixed" environment.

Remote Options
The D22 can be remote controlled via RS-485, allowing the user to change Delay time or even the full setup from a distance. GPI (General Purpose Impulse) allows external control of Tap Tempo as well as Master Fader output.

Ultimate Hardware
The D22 is equipped with industry-leading 24 bit AES/EBU and S/PDIF digital interface and 24 bit A/D-D/A converters. The Delay algorithm itself carries a full 24 bit signal through to the output. Even when bypassing the D22, true 24 bit resolution is maintained, leaving the digital signal untouched. When used in Analog setups the D22 contains Relays, enabling hardwired bypass to ensure uninterrupted signal flow in the event of an unexpected loss of power to the unit.
