RANE AD22S – AUDIO DELAY
The Rane AD22S 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 AD22S offers 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.
The AD22S 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.
The AD22S's balanced XLR inputs and outputs offer 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.
In some situations it may be necessary to recall a stored setting or enable channel bypass from a location other than where the AD22S is located. Have a room divider wall? You can install a switch to select between the two room settings automatically when the wall is moved. Does the delay for your outdoor speaker array change with the temperature? Wire up a switch to change from a memory setting adjusted for one temperature to one saved for the other when the weather warms up. For these reasons we have provided remote recall connections on the rear of the unit that can be wired to standard switches installed in any other location.
