Rane AD 22D Datasheet

Data Sheet-

General Description

The Rane AD 22d is a fully balanced two Input, two Output 

audio alignment Delay providing a range of 1.50 to 999.99 mil-

liseconds on each Output. The Delay of each Output is indepen-

dently adjustable in 10 microsecond and 1 millisecond incre-

ments. 24-bit audio converters provide excellent sound quality.

Each Output has two nonvolatile Memories (no batteries 

required), A and B, for easy access to previously stored Delay 

values. Remote Recall screw terminals on the rear accept external 

configuration switches, permitting independent remote recall of 

the Memories.

The AD 22d features XLR Inputs and Outputs, and is CE 

certified for emissions. Housed in a single rack space, the unit 

can operate as two independent channels (dual mono), or as a 

stereo pair (edit both channels simultaneously).

Delay values can be displayed in milliseconds, feet or meters. 

The ambient temperature of the room may be manually entered 

in degrees Celsius or Fahrenheit. This temperature is used to ac-

curately convert distance into time.

A recessed rear panel switch is available for locking out front 

panel controls. In this mode, all of the front panel pushbuttons 

are disabled with the exception of the Channel select and Dis-

play Mode buttons. The Channel button remains active so the 

user may view the Delay values without risk of changing them, 

and the Display Mode button allows displaying the Delay values 

in milliseconds, feet or meters. Internal jumpers are available to 

enable or disable Bypass while in Front Panel Lockout mode. The 

default setting of these jumpers disables Bypass in Front Panel 

Lockout mode.

Independent bypass relays provide a fail safe, hard-wired 

bypass in case of power loss.

The AD 22d is a unity gain device with Sensitivity controls 

to provide proper internal levels for the audio converters. If the 

input signal is nominally +4 dBu, set the Sensitivity control fully 

counter clockwise (+4 dBu). For those unable to touch a cable 

and determine its signal level, Signal present and Clip indicators 

provide visual acknowledgment that the Input signal is within 

optimal range.

Powered from a low voltage UL listed and CSA certified 

remote power supply (230 VAC supply meets LVD 73/23/EEC), 

the AD 22d is exempt from safety agency requirements, and may 

be used in any installation mandating agency compliance.
