Sound Devices 688 firmware - (v3.01) provides a stability and performance update for the previously released version 3.00, and includes fixes such as for the previously documented known issue whereby the SL-6 RF Scan did not complete correctly when three Wisycom MCR-42s were in use. This firmware release also includes all new features related to automixing, RF scanning, and frequency assignment, first released in version 3.00.

It is highly recommended that users update to the latest version of firmware available as soon as possible.

Download the available 688 User Guide. It is up-to-date with all relevant features and functionality changes provided in the latest released versions of firmware.

Last update April 27,2016

Changes introduced in 3.01 include:

New

  • Scrolling the SL-6 RF Scan plot using the HP encoder now skips over gaps of unused RF frequencies allowing for quicker scrolling through the RF plot.

Changes

  • Lectrosonics SRb and SRc are temporarily set to an output level of -50 dB during the SL-6 RF Scan process. This is to avoid unwanted loud signals sent to the 688 during the scan.

Fixed

  • SL-6 RF Scan does not complete correctly when three Wisycom MCR-42s are in use.
  • General clean up of SL-6 RF Scan with Wisycom MCR42, including faster scan time.
  • Lectrosonics SRb and SRc do not revert to previously selected frequencies after the SL-6 RF Scan when a frequency wasn’t assigned to the Receiver.
  • SRc Block 606 Tx Switches are not displayed correctly in the 688 Rx Screen.

The following list of new features, changes and fixes, first released in v3.00 still apply to v3.01.

New

  • 12-channel automatic mixing with Dan Dugan automixing.
  • MixAssist now allows control of the Off-Attenuation setting. Range is 6 dB to 40 dB in 1 dB increments.
  • SL-6 supports Lectrosonics SRc.
  • The SL-6 supports RF Scan with Wisycom and Lectrosonics SRb & SRc SuperSlot-compatible receivers, which includes:
    • Ability to scan the entire receiver frequency spectrum and display detailed results on the 688's larger, colorful LCD.
    • Use the Select encoder to zoom in and out; Use the Headphone encoder to horizontally scroll through the scan and assign a selected frequency to available receiver channels.
    • Wisycom RF Group Scan from the Wisycom Rx screen: Initiates scan and lists channels for the selected group by returned dBuV values.
    • Lectrosonics RF Scan from the Lectosonics Rx screen: Scans the frequency range of the receiver, displays results, and enables frequency assignment to the receiver's available channels.

Changes

  • CL-12 Fader Calibration now also includes a fader down calibration.
  • Relocated Compatibility on (SL-6) Lectrosonics SRb Rx screen to the SRb menu.

Fixed

  • Unable to use SL-6 Rx Screens to scroll through Lectrosonics SRb user-defined tuning groups U and V.
  • Missing support of Lectrosonics Block 606.
  • Sluggish navigation in the SRb Rx Screen Menus.

Known Issues

The list below are the published known issues for the latest 688 Firmware.

  • The CL-12 does not always initialize when connecting to the 688 if the CL-12's DC Boost Input is connected.
    Workaround:
    When disconnecting the CL-12 from the 688: Remove the DC Boost Input micro USB cable before disconnecting the CL-12/688 USB A to USB B cable. When connecting the CL-12 to the 688: Connect the CL-12/688 USB A to USB B cable before connecting the DC Boost Input micro USB cable.
  • Rare issue where the system clock gets set to an invalid date. This can cause the daily folder to be incorrectly named and therefore the files get stored in the wrong folder. As of V2.00+, if the 688 detects an invalid date, it will display the following message: “System date error detected. Please reset time and date.”

1.00 - initial release

Please read and follow the steps below carefully. You may want to print them before upgrading firmware.

Sound Devices recommends backing up any existing audio data that may reside on the recorder. While no data on the storage is changed during the update process, it is best practice to backup the unit. In addition, it is highly recommended to save the current device settings since a firmware update can result in settings changing to factory default.

Prepare to Update

  1. Download the 688 firmware file 688_3.01.zip using the link below.
    From the zip archive, extract the file within named 688_3.01.prg file. Copy this .prg file to the root level of an approved SD or CF memory card. Do not place the file in any folder. Do not place the 688_3.01.zip file on the SD or CF card. The card must be formatted in the 688.
