Welcome to the SL-2

Streamline your bag with the SL-2 Dual SuperSlot Wireless Module. This two slot-in wireless receiver integration system easily mounts to the top
panel of any 8-Series mixer-recorder. UniSlot and SuperSlot™ wireless receivers from a variety of manufacturers are accepted, including Audio Ltd,
Lectrosonics, Wisycom, and Sennheiser. The SuperSlot protocol supports up to four channels of wireless audio per slot.

An 8-Series mixer-recorder supplies power to the SL-2 and slotted-in receivers - no external DC connector needed. 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 SL-2 offers anten­na distribution to slot-in receivers, spreading out the placement of antennas for better RF performance. 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, each supplying up to 500 mA for powering
additional equipment.

• Compatible with the 833, 888, and the Scorpio.

• Accepts two UniSlot or SuperSlot wireless receivers from Audio Ltd, Lectrosonics, Sennheiser, and Wisycom.

• Built-in antenna distribution with antenna powering for active antennas or boosters.

• Supports remote control of third party smart antennas.

• Two auxiliary MCX antenna ports for connecting other receivers or RF distribution.

• Two TA3 AES3 inputs for an additional 4 channels of digital audio.

• Two DC Outputs via Hirose 4-pin connectors, each supplying up to 500 mA.

• Powers via an 8-Series mixer-recorder.

• Accepts either analog or digital audio from slot-in receivers.

• Ability to set and monitor multiple functions of a SuperSlot-compatible receiver from the 8-Series mixer-recorder.

• RF Scan with visual representation of the RF spectrum.

• Monitor transmitter battery, receiver audio, and RF levels.

• Rugged, lightweight, and compact design.

• Mounts to the top of any 8-Series mixer-recorder.

• Same width as the 833.

We are honored to be part of your kit.

Sincerely,
Sound Devices
