These procedures assume that you have turned on the power to all of the equipment in the A/V Reformatting station via the power battery backup underneath the desk, then booted up the Mac. | + | We currently have the capability of transferring cassette, reel to reel, and mini-cassette.

The archival master should be saved as a **.wav** file and the access copy should be a **.mp3** file. | Generally we will be creating two files: **an archival master** and **an access file**.

| - On the Revox, determine whether the original tape is mono/stereo and turn the "mode selector" on the monitor panel to the appropriate position. You can do this by switching between modes and watching the channel monitors. | - On the Revox, determine whether the original tape is mono/stereo and turn the "mode selector" on the monitor panel to the appropriate position.

| - | - If you are lucky, the tape will have tone at the beginning of the tape (many of the broadcast WFCR tapes have this). Use this to set your levels. Watch the meters on the Revox. Adjust the gain nobs on the front of the Scarlett so that the meters in Audacity or Audition approximately match the levels on the Revox. If there is no tone on the tape, you may have to take a few passes to get the levels right. As a rule you don't want to be hitting 0db ("the red") too often. A good motto is: -12db is the place to be. | + | - If you are lucky, the tape will have tone at the beginning of the tape (many of the broadcast WFCR tapes have this). Use this to set your levels.
