Rane AD22S AD22S Manual - Page 7

OPERATING DETAILS INITIAL SETUP The AD22S is always on while plugged in. When first powered up, the LCD briefly displays the words "Rane AD22S 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. Otherwise press DISTANCE for distance alignment. Both modes offer milliseconds as a simple display option in addition to their distance or video functions. SETTING THE DELAY A '>' by the channel number indicates the channel is selected for editing. This appears on both channels if LINK is active. Distance Mode: Use CURSOR buttons to highlight the unit type, then select between milliseconds, feet, or meters. The AD 22S also needs to know the temperature. To set, select and set the unit type to °C or °F, then select and set the temperature. Video Mode: Choose between frames or milliseconds as the display setting. For frames, the delay value is based on the number of frames per second, denoted by "fps" on the display. Set this first and make sure it matches your video frame rate. Linked Channels: With channels linked, any changes made are applied to both channels at once. This does not force the delay values to be the same. Example: For two speaker arrays at different distances from a performer, linking the two channels lets you change temperature settings for both at once. For stereo operation, set each channel to the same value before pressing LINK. RECALLING DELAYS Press RECALL to copy from the Memory shown to the active setting for the selected channel. If LINK is active, both channels will be recalled. This will overwrite any current settings. REMOTE RECALL The REMOTE RECALL terminals on the rear of the unit are functionally equivalent to the RECALL button. With a switch wired between the RECALL terminal and the GND terminal, close the switch to recall Memory B. Open the switch to recall Memory A. FIRMWARE UPDATE Should a firmware upgrade become available, it will be posted on the AD22S page at www.rane.com/ad22s.html. The USB port provides the connection to a PC enabling the file transfer. Perform the following steps to update: 1. Ensure the unit is powered. 2. Connect via device cable to USB port on computer. 3. AD22S appears as an EXTERNAL DISK device containing one file (named "AD22S_XX.BIN" or similar). 4. Delete this file. NOTE: After deleting this file, the folder may disappear, then re-open after a few seconds. 5. Copy or drag the new firmware file to the AD22S. 6. After transfer, the AD22S restarts automatically and briefly dis- plays the new revision info. It may also reappear as an EXTERNAL DISK on the PC containing the new firmware file. 7. Disconnect USB cable and resume normal operation. Notes: If the revision number displayed does not match the new firmware, make sure you have the latest file and try again. Tip: Press and hold both CURSOR buttons simultaneously for one second to view the currently running firmware version. If an error occurs during transfer or a file is corrupted, the AD 22S will revert to the last working version. STORING DELAYS * The character on the display means the current setting dif- fers from the memory bank shown. Move the CURSOR to the memory field, then press COARSE or FINE to toggle between Mem A or Mem B. Press STORE to copy the current setting into * this location. Note that is no longer displayed. If channels are linked, both channels will be stored. Note: The CURSOR must be on the Memory Bank field to STORE. This is to prevent an accidental overwrite of saved settings. ©Rane Corporation 10802 47th Ave. W., Mukilteo WA 98275-5000 TEL 425-355-6000 FAX 425-347-7757 WEB rane.com Manual-4 111803
