Loudness Test Time Control
Settings for operating automatic, semi-automatic or manual loudness
measurements.
Start:
- Functions: Autostart after preset load, autostart with gate,
autostart with gate and autoreset, manually via
keys or GPI. With Timecode Reader licence
(SW20008) activated additional control via
timecode resp. timecode with recalculation.
