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.
