Sennheiser SL DI 4 XLR是具有四路輸入的Dante前置放大器，非常適合於無線咪高峰接收機使用，並且能夠為一個Dante系統提供咪高峰/線路電平的輸入端口。
概述
SL DI 4 XLR是具有四個輸入Dante前置放大器，非常適合於無線咪高峰接收機使用，並且能夠為一個Dante系統提供咪高峰/線路電平的輸入信號。採用小型化設計的SL DI 4 XLR幾乎能夠固定安裝在任何空間位置，因此可以將它們設置在最靠近聲源的位置，由此減少模擬電線易受的干擾。 SL DI 4 XLR具有四個平衡式咪高峰/線路輸入接口，每一個都可以通過軟件來選擇48伏幻象供電和8級電平增益調整。前面板的指示燈能夠顯示每一個通道的增益和幻象供電的狀態，以便於快速解決所出現的問題。 SL DI 4 XLR還配置了兩個網絡接口，可實現Dante網絡的環接。 Dante環接方式允許多個SL DI 4 XLR共用一根五類雙絞線連接到網絡交換機上，從而更進一步簡化了系統的連線。同時供電也可以通過環接方式來實現。 SL DI 4 XLR可以通過外置12伏直流電或具有PoE功能的網絡交換機來進行供電。所有可調節的參數，如咪高峰/線路電平增益和幻象供電，都可以通過相應的軟件設置來完成。

- 通過一根五類雙絞線將它們連接到網絡交換機
The Sennheiser SL DI 4 XLR four input Dante preamp is the ideal interface for for wireless microphone receivers, and adding mic/line inputs to a Dante system.
Overview
The SL DI 4 XLR four input Dante preamp is the ideal interface for wireless microphone receivers, and adding mic/line inputs to a Dante system. The small form factor to 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 +48V phantom power and 8 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 +12VDC or any PoE network switch. All adjustable parameters, like mic/ line gain and phantom power, are software controlled.
Features
- 4 XLR balanced and RF filtered mic/line inputs
- Gain is individually adjustable per channel via software
- 802.3af compliant PoE powered to work with any compliant PoE network switch, or an external +12VDC 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
