Time-Align Your Sound System's Output!

The Rane AD 22d Audio Delay is the tool you need to time-align your sound system's output! The AD 22d is a fully balanced two input, two output audio alignment delay providing a range of 1.50 to 999.99 milliseconds on each output. The delay of each output is independently adjustable in 10 microsecond and 1 millisecond increments. 24-bit audio converters provide excellent sound quality.

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, which is used to accurately convert distance into time, may be manually entered in degrees Celsius or Fahrenheit.

Memory for preset delay recall
Each output has two nonvolatile memories (no batteries required) for easy access to previously stored delay values. The AD 22d includes remote recall screw terminals on the rear that accept external configuration switches, permitting independent remote recall of the memories.

It's tamper-proof - a must for permanent installations!
A recessed rear panel switch is available for locking out front panel controls. In this mode, all of the front panel push buttons are disabled with the exception of the channel select and display 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. 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. Signal present and clip indicators provide visual acknowledgment that the Input signal is within optimal range.
