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

Attaching the SL-2
Power down the mixer-recorder and remove all power sources.
Proper and complete assembly of the SL-2 is required for optimal RF
emission performance. After removing the SL-2, it is important that
you replace all original screws on the 8-Series mixer-recorder.
See assembly instructions for the 8-Series model for which you will be
attaching the SL-2.
833 & 888
The following instructions describe attaching the SL-2 to the 833 and
888. For this assembly you will need:

to the bottom of the 833/888 for safekeeping.
STEP 3 Using the provided 2 mm Allen Wrench,
screw in two Rear Keyhole Pegs into the threads
where you removed the screws in Step 2.
STEP 4 Align the SL-2’s bottom panel hooks with the Rear Keyhole
Pegs on the 833/888. The SL-2 should be tilted with the front
panel slightly higher than the rear. Take care not to bump the SL-2
expansion connector against the 833/888 top panel. Once the
SL-2’s Bottom Panel hooks and Rear Keyhole Peg’s machined
grooves are aligned, slide the SL-2 towards the front panel.
On an 833, the back of the silver mount screws will rest against this
indent.
STEP 2 Using a #4 Phillips Screwdriver, remove the two black
phillips screws from the Scorpio top panel as shown in the
image below. Keep these screws in a safe place as they need
to be re-installed if the SL-2 is removed from the 833/888.
On an 888, the silver mount screws will t inside this hole.

Inserting Receivers in the SL-2
It is important to turn off power to the SL-2 slot prior to removing
and inserting receivers to avoid potential hardware damage. Slot
power can be turned off in the Menu>System>Expansion Port menu,
Menu>SuperSlot>Options>Slot Power, or by turning the 8-Series
Mixer-Recorder Off.
STEP 1 Remove the Uni Slot adapter plate from your receiver. This
part can be called different things depending on the manufacturer
of your wireless receiver. Wisycom refers to this part as a Flange and
Lectrosonics refers to it as blue bezel. The SL-2 was designed with a
locking mechnism that negates the use of a plate. This also reduces
overall weight and allows for quick installation or removal of receivers.
STEP 2 Remove the Rubber Slot Protector from the SL-2
slot and keep it in a safe place for future use. Reinsert the
Rubber Slot Protector when removing the receiver.
STEP 3 Insert the receiver with the DSub connector
down to mate with the SL-2 DSub connector.
STEP 4 Press in on the Saftey Catch and push the Receiver
Quick Release Lever down. Continue to hold down the lever while
rmly pushing the Rx into the slot. Then release the lever.
Removing Receivers from the SL-2
Press in on the SL-2 Saftey Catch and push the Receiver
Quick Release Lever down. Continue to hold down the lever
while sliding the receiver out of the slot. Release the lever.
Replace the Rubber Slot Protector to prevent against dust and debris.
