User manual RANE AD 22S

[. . . ] The amount of delay needed is the time it takes sound to travel from the stage to the lawn. While in DISTANCE mode, this can be displayed in feet, meters, or milliseconds. VIDEO ALIGNMENT The AD 22S is also excellent for synchronizing audio with video feeds, especially in a live environment where video processing typically adds several milliseconds to the signal that can have a noticeable effect on the final output. To assist in this application, the AD 22S can show your delay value directly in terms of frames. [. . . ] If channels are linked, then both are recalled. 9 BYPASS buttons: Toggle relays for each channel. If LED is on, bypass is enabled and the device functions like a wire. If bypass LED is off, the channel is active. 0 SIGNAL / OVERLOAD LEDs: SIG LEDs indicate signal presence on the input. OL LEDs light red when an input signal is near the maximum level and may clip. 3 2 1: >2:[ 45 25. 50 Feet 2. 74]Meters 67 80 °F 27 °C 8 Mem A * Mem B 3 92 >1:[ >2:[ 45 2. 5]Frames 3. 0]Frames 67 29. 97 fps 29. 97 fps 8 Mem A * Mem A 9 1 Distance Mode 1 Video Mode DISPLAY: DISTANCE MODE 1 Cursor 2 Active Channel(s) 3 Channel # 4 Delay Setting 5 Units (Feet, Meters, ms) 6 Temperature 7 Temp.

This port provides no other functions and should not be connected during normal use. 6 UNIVERSAL POWER SUPPLY: Universal IEC power jack connects anywhere in the world to AC line voltage, 100-240 VAC @ 50 ­ 60 Hz. Manual-3 OPERATING DETAILS INITIAL SETUP The AD 22S is always on while plugged in. When first powered up, the LCD briefly displays the words "Rane AD 22S Audio Delay" and the current firmware revision. Out of the box, both channels are in BYPASS mode with the inputs routed directly to the outputs. This makes it easy to set up and verify that signals are present before turning on any delay. The yellow bypass indicators mean that BYPASS is active; press each BYPASS button to disable. ALIGNMENT MODE Two modes of operation are available. If working with video and wish to set delay by number of frames, press VIDEO for video alignment. [. . . ] NOTE: After deleting this file, the folder may disappear, then re-open after a few seconds. Copy or drag the new firmware file to the AD 22S. After transfer, the AD 22S restarts automatically and briefly displays the new revision info. It may also reappear as an EXTERNAL DISK on the PC containing the new firmware file. [. . . ]
