The A20-Mini transmitter introduces GainForward, a new feature that eliminates the need to adjust microphone preamplifier gain at the wireless transmitter. Audio levels from the transmitter are controlled either directly at the mixer’s trim control or at the wireless receiver. Read more about GainForward.
Support for A20-Mini GainForward. When the A10-RX receiving an A20-Mini signal is slotted into the SL-6, the A10-RX Input menu settings are bypassed and all gain, low cut, and limiter activity are performed and controlled by the 688. Trim gain range is 0 to 60 dB for the 688 channel receiving signal from the A20-Mini.
A10-RX Receiver Setup screens show Limiter, High Pass Filter, and clipping status of the associated 688 channel when receiving signal from the A20-Mini.
A10-RX Receiver screens now display overload, mute, and record status of A10-TX.
SuperSlot Receiver Overview screen now shows record status of the A20-Mini and A10-TX.
Fixed
SL-6 related screens no longer display incorrect values for the A10-RX Y (7 MHz) TV channel mapping.
As productions continue to use more microphones simultaneously, producing a clean mix with intelligible speech can become quite difficult. Automatic mixers can help sound professionals in these multi-microphone applications.
The Scorpio, 888, 833, 633, and 688 offer two automatic mixing algorithms: Sound Devices’ own MixAssist and Dugan Automix, a collaboration between Sound Devices and Dan Dugan Sound Design, Inc.
Sound Devices extensively tests removable recording media with the 633, 664, and 688.
For best media performance, Sound Devices recommends occasionally performing a full reformat of an SD card per the “Overwrite Format” method from the SD Association. The Overwrite Format deletes file/directory entries by initializing file system parameters of the card (same as with Quick Format), and erases all data by overwriting the user data area completely. The Overwrite Format takes more time to complete than the Quick Format method. More information can be found on the SD Association’s website. Please note that all files stored on the card will be lost during the formatting process. After using the SD Memory Card Formatter, the card will still need to be formatted in the mixer-recorder.
MicroSD to SD Card adapters are not recommended for use in any 6-Series mixer-recorder.
Tested cards:
Sound Devices’ own brand of approved media cards – the SAM-64SD, SAM-128SD, and SAM-32CF II – have been optimized and extensively tested to ensure fast and flawless performance when used with the 6-Series of mixer/recorders.

The cards from other manufacturers listed below have successfully passed benchmark testing with the 633, 664 and 688. Many other cards may work but their performance and reliability cannot be confirmed unless they have been extensively tested at Sound Devices.

* Note 1: Sound Devices has worked directly with Delkin to identify an intermittent Media I/O issue with newer Delkin CF 500x and CF 700x cards. Delkin has confirmed that a recent change to these two cards is most likely responsible for the errors. Cards containing KZ in the serial number are susceptible to this issue and should not be used. Cards containing VB in the serial number will function correctly and are approved. Deklin CF 1000x and 1050x cards do not experience this issue and may continue to be used.
