Architectural Specifications
The digital audio delay unit shall be a single rack space, two
input, two output configuration. The delay adjustment range
shall be from 1.50 to 999.99 ms, adjustable via increment/decre-
ment pushbuttons, in both 10 microsecond and 1 millisecond
intervals. Independent remote recall terminals shall be provided
for external recall of stored configuration memories, two per
channel. A five (5) digit LED display shall indicate delay values
in milliseconds, feet or meters as well as temperature setting and
software revision level. Bypass status, current memory, channel,
and display modes shall be indicated with individual indicators.
A recessed rear-panel switch shall disable the front panel, yet
still allow viewing of delay values.
Independent input-output sensitivity controls shall be
included to allow calibration of the input signal for maximum
performance. The inputs and outputs shall be active balanced
with XLR connectors. Each channel shall have indicators for
signal present and input/output clip conditions.
The unit shall provide independent, fail-safe bypass relays
requiring no power to engage. RFI filters shall also be provided.
The unit shall have certified compliance with FCC docket
20780 Part 15J for Class B computing devices. The AD 22d shall
comply with EMCD 89/336/EEC (CE approved). The 120 VAC
model shall be powered from a UL listed, CSA certified remote
power supply, and the 230 VAC model shall be powered from
a remote power supply meeting LVD 73/23/EEC and EMCD
89/336/EEC standards. The unit shall be constructed entirely
