Product Description

Rane AD 22D is a fully balanced, 2-in/2-out, professional audio alignment delay, intended for use with live or installed PA systems, and providing a delay range of 1.50 to 999.99 ms on each output. The unit is housed in a rugged, single-space metal rackmount chassis.

The delay of each AD 22D output is independently adjustable in 10µSec and 1 ms increments. 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. The temperature is used to accurately convert distance into time. The unit features 24-bit audio converters for consistent sound quality.

Each AD 22D output is equipped with 2 non-volatile 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 can operate as two independent channels in dual mono, or as a stereo pair, allowing for simultaneous editing of both channels. This unit is a workhorse product offering technology and reliability at a reasonable price.


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.
