General Description
e Rane AD 22S is a fully balanced two-input, two-output
Audio Delay unit designed for multiple applications, including
speaker array synchronization and precision audio-to-video
alignment. With two distinct modes, the AD 22S oers the
functionality of dedicated devices within a single rack unit.
Featuring a range of 2.00 to 999.99 ms, this unit provides delay
displayed in units of time, distance, or frames. Use the dedicated
Video mode to provide almost a full second of audio delay in 0.5
frame increments for all standard NTSC or PAL/SECAM frame
rates.
e AD 22S can operate as two independent channels or as a
linked or stereo pair. Front panel controls let you choose settings
for each channel that can be stored into two nonvolatile memory

locations for quick and easy access at any time. Bypass relays
for each channel automatically connect should the device lose
power. Your settings are always saved into working memory and
restored upon power up. Rear terminals let you connect standard
switches to recall settings remotely.
e AD 22S’s balanced XLR inputs and outputs oer the
Rane standard of audio quality, with 24-bit processing and
delay precision down to 0.01 ms. With the ability to provide
unity gain up to a maximum input level of 24 dBu, the unit can
be used with standard high-impedance devices or in a mixed
environment using 600 Ω equipment. LEDs on the front panel
indicate signal presence and alert when the signal is nearing the
maximum input level.
