The SL DI 4 XLR Dante™ interface
The SL DI 4 XLR is a Dante™ interface with four inputs. This lets you integrate wireless microphone
receivers or mic/line inputs into a Dante™ system. The compact design of the SL DI 4 XLR allows
it be mounted almost anywhere, enabling close placement to audio sources and thus reducing the
need for interference-prone analog cables.

Daisy-chaining the power supply
The PWR LINK IN and OUT terminals allow you to daisy-chain the power supply to additional de-
vices.
The number of devices that can be daisy-chained is limited.
• NT 12-50CS power supply -> maximum of 3 devices.
• Power over Ethernet -> maximum of 2 devices
WARNING!
DANGER OF INJURY DUE TO MISSING OVERLOAD PROTECTION!
IF THE DAISYCHAINING OF THE POWER SUPPLY IS NOT DONE PROPERLY, THIS MAY CAUSE IN
JURY DUE TO ELECTRIC SHOCK.
Only have the daisy-chaining of the power supply done by a qualified specialist.
Connecting audio signals
You can connect a total of four analog audio signals (e.g. from microphone receivers (SL Rack
Receiver DW) or wired microphones) to the SL DI 4 XLR.
You can change the settings for the respective microphone input using the SL DI CONTROL soft-
ware (see „Configuring the SL DI 4 XLR using the SL DI CONTROL software“).
To connect analog audio signals to the SL DI 4 XLR:
Use an XLR-3 cable to connect the audio device to one of the four XLR inputs.
Via the DATA and POE + DATA Ethernet sockets, the audio signals are routed, using Dante™, to a
Dante™-enabled device.
The destination of the Dante™ stream is configured using a Dante™ software controller. This con-
troller is not part of the SL DI CONTROL software..
