The Sennheiser SL DI 4 XLR four input Dante™ preamp is the ideal interface for use with SpeechLine microphone wireless receivers and adding mic/line inputs to a Dante™ system. The small form factor of the SL DI 4 XLR allows them to be mounted almost anywhere, putting them close to audio sources and minimizing interference-prone analog wiring.
The SL DI 4 XLR features four balanced mic/line inputs, each with software selectable +48 V phantom power and different gain levels. Front panel indicators show each channel’s gain and phantom power status for easy troubleshooting. The SL DI 4 XLR has two network connections to allow Dante™ Daisy Chaining. Dante™ Daisy Chaining further simplifies system infrastructure wiring by allowing multiple SL DI 4 XLRs to use a single CAT 5 home run connection to a network switch. Power can also be daisy chained. The SL DI 4 XLR is powered by either external +12 V DC or any PoE network switch. All adjustable parameters, like mic/line gain and phantom power, are software controlled.
