High resolution Delay for broadcast master control and linking. Delay-time may
be adjusted while signal is being passed, thanks to a low artifact processing
technique. The delay is easily adjustable from the front panel using dedicated
Nudge keys, Encoder and Tap function. Increments can be set in ms, fields or
frames, and the unit delays linear audio as well as Dolby E or AC3 streams. Remote
control of by-pass and delay time is available through GPI or RS485 inputs.
Balanced and unbalanced AES/EBU I/O is standard, and outputs are always active.
Sample rate conversion can be invoked when using digital inputs.
Analog I/O is standard, and outputs are always active. The 24 bit converters are scaled
in the analog domain, with scaling under preset control, to minimize noise and maximize
headroom under all operating conditions.

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.
