What is SuperSlot?SuperSlot™ is an open, electro-mechanical connection specification, developed by Sound Devices, to simplify the interconnection of wireless audio transmitters and receivers with audio mixers and cameras for the entire industry to use. SuperSlot provides power, audio, and control signals over a single multi-pin connection. SuperSlot-compatible products are offered by multiple manufacturers. Read more about SuperSlot here.
Which SuperSlot receivers are supported by SL-2?SuperSlot is an open standard. Wireless receivers from several manufacturers are supported, allowing you to use your favorite brand, as well as leveraging your existing transmitter and receiver investment:
Audio Ltd A10-RX
Lectrosonics SRb (with audio board update from Lectrosonics)
Lectrosonics SRb5P and SRc5P (Slot A only)
Sennheiser EK-6042 (does not support scan)
Wisycom MCR42 (with SLK42-IKSS rear panel adapter from Wisycom)
What features of a given receiver does SuperSlot support?The 8-Series automatically powers all receivers slotted-in the SL-2 on and off with the mixer-recorder. After power on, the 8-Series mixer-recorder automatically sets the output of the receiver to analog or digital and sets the output level to achieve maximum dynamic range. The 8-Series menus provide access to RF scan, menus for receiver setup, RF frequency adjustment, TX status, RF and audio level monitoring, TX recording status, TX Limiter and overload status (A10-TX only) and more. Features available depend on the receiver in use.
Does the SL-2 work with all the 833, 888, and Scorpio mixer-recorders?Yes it does! It is the same width as the 833, making it a perfect fit for production bags.
How does the SL-2 attach to the 8-Series mixer-recorder?The SL-2 assembly instructions can be found in the SL-2 User Guide, available on the downloads page.
What is the combined height of my 8-Series with the SL-2 attached?The SL-2 adds 1.8 inches (or 4.5 centimeters for our metric friends). The Scorpio, 888 and 833 mixer-recorders all have the same height of 2.0 inches (5.1 centimeters) bringing the total height to 3.8 inches or 9.6 centimeters.
How many receivers can I use?The SL-2 accepts two slot-in Unislot or SuperSlot wireless receivers.
Do I need to attach the adapter plate to my receiver before putting it in the SL-2 slot?The SL-2 was designed to house receivers without the adapter plate (also referred to as flange or bevel). The SL-2’s quick receiver locking mechanism negates the need to secure the receiver in the slot with cumbersome screws. An added bonus is your bag just got two adapter plates lighter!
How many channels per slot does the SL-2 support?The SL-2 supports the SuperSlot spec, which has always supported up to four audio channels per slot. When used with two Wisycom MCR54 receivers, the 8-Series can receive up to eight channels of wireless audio.
How many channels of audio can I send from the SL-2 to my 8-series mixer/recorder?The SL-2 has 12 selectable audio sources and can send up to 8 channels of audio to the mixer/recorder. 8 channels are available if all sources are AES digital. If a slot receiver output is analog, 6 channels are available and AES 3 and 4 cannot be selected.
I see the SL-2 can support four channels per slot. How about the SL-6?Even though the SuperSlot protocol supports four channels per slot, and several other functions, the SL-6 hardware can support only two channels per slot.
Will the SL-2 power my antennas?Yes. Both SMA antenna connectors provide 12 V bias power up to 500 mA.
Does the SL-2 support smart antennas?The SL-2 supports the Wisycom LFA-B-F1. Antenna filter frequency and gain is controlled directly from the 8-series/SL-2. All data is sent to the antenna using the BNC RF signal cable. This allows for long cable runs, with the antenna being placed closer to the talent, significantly improving wireless reception. Watch our tiptorial.
Does the SL-2 have a battery slot?To keep the size and weight of the SL-2 to a minimum, the SL-2 was designed to receive all necessary power from the 8-Series Mixer-Recorder.
Does the SL-2 have any power distribution?Yes. Based on feedback after the initial SL-2 announcement, we added two DC outputs via 4-pin Hirose connectors on the rear panel. Each output can supply up to 500 mA.
Is there built in RF filtering in the SL-2?Yes. The filtering is menu-selectable from the 8-Series user interface and covers ranges of 470-1260 MHz.
Does the SL-2 have RF attenuators?There are attenuators at the input of the RF stage that can be enabled in the 8-Series menus.
This is useful when experiencing heavy RF overload.
Can I use the SL-2 with my XL-AES?The SL-2 utilizes the same expansion port as the XL-AES so simultaneous use is impossible. However, the SL-2 does have two TA3 AES3 inputs for up to 4 additional channels of digital audio in.
Is there a ribbon cable or does the SL-2 affix to the port directly? Can I move it?The SL-2 connects directly to your 8-Series mixer-recorder without the use of ribbon cables. The SL-2 sits securely on top with the receivers facing you, allowing for ease of viewing while in your bag or on your cart.
Are there RF loop-through connectors on the SL-2?Yes, these are intended as an extra set of RF connections to another receiver or distro.
Is the SL-2 stackable?The SL-2 is designed to be as lightweight and small as possible, and thus does not include provisions for stacking.
How big is the SL-2?The SL-2 is the same width as the 833.
When will the SL-2 ship?The SL-2 is shipping now. Contact your favorite reseller to place your order.
How much does the SL-2 cost?Please contact your preferred reseller for pricing.
What is the warranty period for the SL-2?Like all of our products, the SL-2 is guaranteed under our warranty for 2 years when you register at sounddevices.com.
Can I use it with my SL-6 on Scorpio at the same time?The SL-2 will not work in conjunction with the SL-6.
Will the SL-2 work with the 6-Series or MixPre II?The SL-2 is an all-new design and will not work with the 6-Series or MixPre II Series.
