Sennheiser Speechline Overview

The SL DI 4 XLR from Sennheiser is a four input Dante preamp and interface for wireless microphone receivers with mic/line inputs to a Dante system. It can be mounted and used almost anywhere close to audio sources and minimizing interference-prone analog wiring in wireless applications.

Featuring four balanced mix/line inputs, each with software-selectable 48V phantom power and different gain levels, the interface provides front-panel LED indicators for showing each channel's gain and phantom power status, which makes for easy troubleshooting.

Plus, it has two network connections to allow Dante Daisy Chaining. This allows you to have multiple SL DI 4 XLR units and use a single Cat-5 home-run connection to a network switch for daisy chaining power. The unit is powered by either an external 12 VDC or any PoE (Power over Ethernet) network switch. All adjustable parameters such as mic/line gain and phantom power are software controlled.

Four XLR balanced and RF filtered mic/line inputs
Gain is individually adjustable per channel via software
802.3af compliant PoE (Power over Ethernet) powered to work with any compliant PoE network switch, or an external +12 VDC power supply
48V phantom power – powers virtually all types of phantom powered microphones typically used in installed AV systems. Phantom power is switchable per channel via software
ID LED allows easy identification of the SL DI 4 XLR
Dante Daisy Chaining allows multiple SL DI 4 XLRs to be connected over a single home run to the Ethernet switch
