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 Sound Devices, Audio Ltd, Lectrosonics, Sennheiser, Shure, Sony, 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
About this User Guide
This SL-2 User Guide covers hardware explanations, device specifications, instructions for attaching the SL-2 to your 8-Series Mixer-Recorder, and the SL-2 Declaration of Conformity.

Panel Views
ANTENNA A & B SMA CONNECTORS Connects antenna to the SL-2. Both SMA antenna connectors can provide 12 V bias power up to 500 mA via a menu option. RF frequency range covers 470 - 1525 MHz. RF Filtering is available in the menus.
RX SLOT A & B Accepts Slot-in Unislot or SuperSlot receivers. Connects via DB-25 connector. SL-2 automatically locks the receiver in place. No screws are necessary to secure the receiver in the SL-2 slots. Cover empty slots with the included Rubber Slot Protector when not in use.
SLOT A & B ANTENNA A LEAD Distributes Antenna A to the left SMA connector of your receiver.
SLOT A & B ANTENNA B LEAD Distributes Antenna B to the right SMA connector of your receiver.
AES INPUTS 1 - 4 Accepts up to four AES3 signals via the TA3-M input connectors. Each connector accepts two channels of AES3. Incoming signal can be routed to 8-Series Mixer-Recorder channels via the menus. Input type: AES3, balanced, TA3F connectors, Impedance: 110 ohms, Sensitivity: 200 mV or higher accepted Wiring: pin 1 = ground; pin 2 = +; pin 3 = –.
DC OUTPUTS 1 & 2 Each Hirose 4-pin male connector provides 6-18 V DC at 500 mA [pin-4=+, pin-1=-]. Useful for providing power to other peripherals such as RF equipment. Power can be defeated in the menus.
ANTENNA A & B RF OVERLOAD LEDS Each antenna input on the front panel of the SL-2 has an associated LED that displays incoming RF level status.
Red = approaching RF overload threshold of the SL-2
Orange = approaching overload threshold of digital wireless systems
Off = no overload
To disable the LEDs go to SL-2 Options>Antenna LEDs and set to Off.
A & B AUX ANTENNA MCX CONNECTORS Distributes Antenna A and B to external receivers.
RECEIVER QUICK RELEASE LEVER & SAFETY CATCH To eject slotted in receivers, press in on the Safety Catch with one finger then push the lever down. Continue holding the lever down, then pull the receivers out of the slot with your other hand.

Removing the SL-2
Power down the mixer-recorder and remove all power sources.
Proper and complete disassembly of the SL-2 is required for optimal
performance. After removing the SL-2, it is important that you replace
all original screws on the 8-Series mixer-recorder.
833 & 888
The following instructions describe removing the SL-2 from the 833
and 888. For this assembly you will need:
- 833 or 888 Mixer-Recorder (not included)
- SL-2
- 2x Rear Keyhole Pegs
- 2 mm Allen Wrench Hex 2-1/16”L
- #4 Phillips Screwdriver (not included)
- Remove any receivers, antennas and cables connected
to the SL-2. Locate the two holes shown in the photo above.
- Insert the allen wrench into these holes, visually confirming that the wrench is in contact with the safety
screws inside the SL-2. Turn the wrench counterclockwise to loosen the screws. Remove the screws and set aside.
- Gently raise the SL-2 and slide slightly forward to disconnect from the mixer-recorder.
- Remove the two silver mount screws using the provided allen wrench.
- Replace the originally provided rear black screws near the Sound Devices logo using #4 Phillips head screwdriver.

SCORPIO
The following instructions describe removing the SL-2 from the Scorpio. For this assembly you will need:
Scorpio Mixer-Recorder (not included)
- SL-2
- 2x Rear Keyhole Pegs
- 6x Screw 6 mm STEEL M3 low-profile
- Scorpio Front Bracket
- SL-2 Rear Bracket
- 2 mm Allen Wrench Hex 2-1/16”L
- #4 Phillips Screwdriver (not included)
- Remove any receivers, antennas and cables connected to the SL-2. Remove the two small black screws securing the SL-2 to the safety mount.
- Gently raise the SL-2 and slide towards the rear of the unit. Lift up and over the silver mounting screw circled in red.
- Remove the two small black screws.
- Remove the safety mount from the top panel of Scorpio.
- If desired, remove the additional Scorpio mounting hardware from the SL-2.
- Perform steps 4-6 of 833/888 disassembly on Scorpio.
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.
- 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.
- 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.
- Insert the receiver with the DSub connector down to mate with the SL-2 DSub connector.
- Press in on the Saftey Catch and push the Receiver Quick Release Lever down. Continue to hold down the lever while firmly pushing the Rx into the slot. Then release the lever.
Removing Receivers from the SL-2
Press in on the SL-2 Safety 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.
