552 User Guide

Released: November 03, 2011

New
- Save and load user settings to internal memory
Fixed
- Improved transport control preventing semi-lockup conditions with some SD cards.
Known Issues
- SD cards 64 GB and larger are not supported.
- Intermittent issue with feeding AES/EBU from the 552 to some Sony cameras (e.g. F5, F55) where the camera will occasionally report "Input AES/EBU is not Pro Use". Workaround: Reboot the 552 or toggle the 552 sample rate from 48kHz to 96kHz and back again.

New
- Input Mute from Mix. Using the front panel shortcut HP press + Input PFL an input can be removed from the Master Output bus. The input still appears at its direct output and if selected as an option for AES output.
Changed
- Input PFL now indicated with a flashing yellow input LED. Original indication was solid yellow.
- In the absence of a time code signal, timecode & speed related metadata is not written. This is to prevent Final Cut Pro from introducing unintended sound file speed changes. The 552 continues to write the time-of-day value as a start time code stamp in bEXT when time code is absent.
