Introduction
Introduction
LC16D Network audio converter
LC16D is a multichannel converter that bridges MADI and AES/EBU legacy digital formats bidirectionally with a Milan-
AVB network. Supporting up to 128 Milan-AVB inputs and outputs simultaneously, LC16D offers dynamic mapping of
channels, and comprehensive synchronization options, with remote control via a simple to use embedded web interface.
Flexible power options and seamless Milan-AVB network audio connections deliver robust redundancy features as
standard, all housed in a compact and rugged 1RU chassis.
Up to 16 AES/EBU inputs and outputs can be connected using standard DB25 connectors. Asynchronous sample rate
converters (ASRC) are implemented on each AES/EBU input. A pair of BNC connectors provide access to MADI. At a
sampling rate of 96 kHz, 32 input and 32 output channels are supported, and up to 64 at 48 kHz. Used together, up
to 80 input sources and 80 output destinations can be connected and dynamically mapped to and from a redundant
Milan-AVB network. The comprehensive clocking options facilitate the selection of a reference from any of six different
sources, which is then presented to all outputs, enabling clock distribution across a system. Up to three levels of power
redundancy are available using a combination of the internal PSU and the dual, PoE-supporting, Ethernet ports.

Installation
Power over Ethernet
LC16D is a Class 3 Powered Device (PD) featuring seamless power redundancy between the mains input and PoE (Power
over Ethernet). In case of failure of the mains power supply, a third-party Power Sourcing Equipment (PSE) can power
LC16D through either of the 1 Gb/s Ethernet ports (PoE1 and PoE2). LC16D is compatible with any IEEE 802.3at-2009
PSE.
When LC16D is connected to three power supplies (mains and two PSEs), it is powered by the mains power supply in
priority. In case of failure of the mains power supply, LC16D is powered through the rst PoE1 (second priority after the
mains). In case of a failure of the PSE connected to PoE1 during a failure of the mains power supply, LC16D is powered
through PoE2 (third priority). LC16D automatically switches back to PoE1 or the mains as available.
The PSE can be a PoE injector, or a PoE switch. PoE switches should be AVB-capable switches if LC16D is used in an
Milan-AVB network.
Use CAT6A U/FTP patch cables (straight-through), AWG24, 50 m / 164 ft min to 100 m / 328 ft max.

Installation
MADI audio
Use the two MADI BNC connectors for AES10-2003 signal cabling.
Both connectors are 75 Ω terminated.
IN
OUT
MADI WORD
MADI IN can receive up to 64 AES10 digital audio signals at 48 kHz or 32 AES10 digital audio signals at 96 kHz.
There is no sample rate conversion. The default mapping is to output streams 3 to 10 (at 48 kHz) or to output streams 3
to 6 (at 96 kHz).
MADI OUT can transmit up to 64 AES10 digital audio signals at 48 kHz or 32 AES10 digital audio signals at 96 kHz.
There is no sample rate conversion. The default mapping is from input streams 3 to 10 (at 48 kHz) or from input streams
3 to 6 (at 96 kHz).
Word clock
Use the two WORD BNC connectors for word clock cabling.
Both connectors are 75 Ω terminated.
IN
OUT
MADI WORD
The supported input frequency is 48 kHz or 96 kHz. WORD IN accepts input levels from 1 Vpp to 5 Vpp, and is
protected from overvoltage. WORD OUT output level is 5 Vpp into open load.

Installation
Milan-AVB
Use the two etherCON connectors for the remote control of LC16D using the LC16D embedded Web interface and an
AVDECC Controller (like Hive). The etherCON connectors are AVB-capable. Real-time audio trafc and control trafc
are automatically managed by Milan-AVB on the same network.
LINK/ACT 1 LINK/ACT 2
In normal network mode, the two etherCON connectors are part of an internal Milan-AVB switch.
In redundancy mode, the two etherCON connectors are independent. The LINK/ACT 1 connector is used for the primary
network, and the LINK/ACT 2 connector is used for the secondary network.
LC16D can receive and send up to 16 streams in normal and in redundant mode, with up to 8 channels per stream, at
48 kHz or 96 kHz (depending on the unit setting).
Do not create loops in the network setup.
In daisy-chain networks, always place LA4X with hardware version* ID1, ID2 or ID3, LA4,
and LA8 after any other type of amplied controller.
These amplied controllers are equipped with former generation 100 Mb/s Ethernet ports that cannot
communicate with Ethernet ports of different capabilities, creating detection issues in LA Network Manager.
*The LA4X hardware version is visible in the MONITORING & INFO menu (HARDWARE INFO section).
