Sound Devices 552 Mixer firmware revision 1.20 provides the following new features and changes:
addition - 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.
change - Input PFL now indicated with a flashing yellow input LED. Original indication was solid yellow.
change - 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 when time code is absent.

Firmware Installation Instructions
Please read and follow the steps below carefully. You may want to print them before upgrading firmware.
Prepare to Update
Before upgrading the firmware on the 552 from the original revision 1.0 release, the digital outputs MUST BE TURNED OFF. The update will fail if the outputs are set to AES. If upgrading from any later version than 1.0, this step is not necessary.
Download the 552 firmware file 552_1.20.zip using the link below.
From the zip archive, extract the file within named 552_1.20.prg file. Copy this .prg file to the root level of a SD or SDHC memory card. Do not place the file in any folder. The card must be formatted as a FAT32 volume.
Apply Update to 552
Power the 552 from a fresh set of batteries or from external DC. Do not perform the update with low batteries or unstable power sources.
Power down the 552 if it is already powered up.
Connect headphones so that you can hear SVEN.
Insert the SD card with the .prg file.
Power on the 552. With the new firmare on the inserted SD card, the mixer will auto-detect the new file and SVEN announces "Software update, press Battery Button if OK, press Stop to cancel."
Press the Battery Button to continue. SVEN announces "Checking file integrity,", then "Programming, please wait,", then "Verifying, please wait." When the update is complete SVEN announces "Update finished, please turn off power to complete".
Power down the 552.
Power the 552 on. The meters will "dance" and briefly pause on -30 LED on the left meter and -24 on the right meter, this indicates that the 552 is running the 1.20 revision of firmware. Please note the changes and additions to the Setup Menu. Consult the 552 User Guide and Technical Information for details.
