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.
Connections and setup
1) Connect the MIDI/FSK output from your sequencer, rhythm machine, or converter to one of the
MIC/LINE INPUT connectors.
2) Set the input select key for the corresponding channel to the MIC/LINE position.
3) Rotate the GAIN control fully counter-clockwise to the LINE setting.
4) Set the equalizer controls to the “0” (flat) position.
6) Set the channel fader to the nominal level between “7” and “8”.
7) Press the REC SELECT key for track 4.
The REC SELECT - TRACK indicator on the display will flash.
8) If dbx™ system is on, press the SYNC key (K).
The SYNC indicator (]) on the display will light.
9) If you are going to record audio signals from the MIDI instrument along with the FSK signal,
connect the audio outputs to the channel connectors and set the mixer channels. See "Initial
recording" on page 15.
Rehearsal
10) Press the REHE key to put the MT4X into rehearsal mode.
11) Start the MIDI instrument and adjust the recording levels.
Adjust the level of the FSK signals so that the level meters indicate about +6 dB.
12) Adjust the monitoring levels.
13) Stop the MIDI instrument.
Record the sync track
14) Fast-wind or rewind the tape to the beginning of your recording. Press the COUNTER RESET key to
set the tape counter to “0000”.
15) Press the REC/PAUSE and PLAY keys to start recording.
5) Press the ASSIGN
key: and rotate the
PAN control: fully clockwise to select the fourth (even)
group - track 4.
Note: These instructions assume you have recorded a song on your MIDI sequencer or rhythm machine that
consists of a song start, tempo, and a song end. If you programmed tempo changes, these will also be recorded on
the FSK track.
