Sound Devices 552 Field Mixer Firmware 1.4 Description

New:

- Save and load user settings to internal memory.

Fixes:

- Improved transport control preventing semi-lockup conditions with some SD cards.

Known Issues:

- The list below are the published known issues for the latest 552 Firmware.
- 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.

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.
- From the zip archive, extract the file within. 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 firmware 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 -20 on the right meter, this indicates that the 552 is running the X revision of firmware. Please note any changes or additions to the Setup Menu (if applicable).

About DJ Mixers:

Updating the mixer’s firmware version can add support for newly developed features (or improve existing ones), enhance audio quality and transition effects, resolve different problems such as those regarding various noises heard in certain situations, and many other related improvements.

However, before downloading this package, go to the unit’s system information and make sure that the currently installed firmware isn’t either newer or matches this release. Moreover, you should know that an update failure might seriously damage the mixer’s software, so it is vital that you are familiar with the installation steps.

As for applying this release, you must transfer the downloadable package (or its content) to the mixer via any available methods, and power up the unit through various key combinations in order to enter update mode (make sure you read the product’s user guide).

This said, if you consider installing this release and you’re positive you have all the knowledge you need for a successful upgrade, download the package, and apply it to your mixer. Check with our website constantly so that you don’t miss any update that can improve your device. 

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
