FSK recording

Record FSK signals on track 4
The MT4X is equipped with a dbx™ noise reduction system. For recording normal audio
signals, the noise reduction system is beneficial. However, dbx™ interferes with the
recording of FSK signals. This sometimes results in an unusable sync track. Therefore, the
MT4X is also equipped with a SYNC key. When you press the SYNC key, the dbx™ system
is defeated on track 4, allowing you to have noise reduction on your audio tracks and a
usable sync track.
