In addition, the SL-2 and slotted-in receivers can get power from the 833, 888, or Scorpio, eliminating the need for external DC connector. Also, analog or digital audio is sent from the receivers into the mixer-recorder via the expansion port, reducing messy cabling for power and audio connectivity.

The new Sound Devices SL-2 offers antenna distribution to slot-in receivers, spreading out the placement of antennas for better RF performance. Moreover, the rear panel of the SL-2 is equipped with two TA3 connectors for an additional four inputs of AES3 audio and two 4-pin Hirose DC Outputs. As such, each of these can supply up to 500 mA for powering additional equipment.

However, in order to operate the SL-2 you have to download firmware v6.00, which is now available from Sound Devices. In addition to supporting the SL-2, version 6.00 introduces RF history for supported SuperSlot receivers mounted in an SL-2 or SL-6.

Also, you can learn more about all enhancements in firmware v6.0 here.
