Architectural Specifications

The digital audio delay unit shall be a single rack space, bal-

anced two-input, two-output configuration. The delay adjust-

ment range shall be from 2.00 to 999.99 ms, adjustable in 0.01

ms increments via increment / decrement pushbuttons, in 10 µs

or 1 ms intervals. Additionally, the values shall be selectable in

terms of distance in feet or meters, as well as in frames for all

common NTSC and PAL / SECAM frame rates.

A 40x2 backlit character LCD shall indicate current delay

settings and provide cursor controls for selecting and setting the

delay values and configuration parameters, including tempera-

ture, frame rate, and stored memory values. Bypass status, signal

/ overload presence and mode of operation shall be indicated

with individual indicators.

Terminals on the rear panel shall allow remote disabling of

the front panel controls and bypass switches. Additional termi-

nals shall provide access for remote switches to recall memory

settings.

The inputs and outputs shall be active balanced with XLR

connectors, and include switchable fail-safe output relays on each

channel that automatically enable in the event of power failure.

RFI filters shall be provided.

The unit shall be capable of operation by means of its own

built-in universal power supply operating at 100-240 VAC and

meet CE requirements. The unit shall be UL and cUL listed.

The unit shall be a Rane Corporation AD22S.
