The optional SL-6 powering and wireless system simplifies interconnection between the 688 and multiple channels of wireless by accepting three dual-channel slot-in receivers. The SL-6 offers all powering and audio interconnection for standard slot-in receivers and additional control and monitoring when used with SuperSlot-compatible receivers. The SL-6 easily attaches directly to the 688's top panel and also offers antenna signal distribution to further declutter the bag.
With its NP1 battery slot, USB charging port, two 12 V isolated outputs, and two non-isolated direct battery outputs, the SL-6 is a great powering hub for peripheral devices in a sound mixer's bag.
Regarded as the industry’s first non-proprietary, open wireless control and interfacing standard, SuperSlot, developed by Sound Devices, is the result of its collaboration with a number of leading wireless manufacturers including Lectrosonics, Wisycom, Sennheiser, and Audio Ltd. The standard allows for all powering and audio interconnection, plus control and monitoring between SuperSlot-compatible mixers and receivers. When used with SuperSlot-compatible receivers, the SL-6 enables RF spectrum scanning and frequency assignment directly from the 688's LCD.
