U-Hub

Introduction

The Martin Audio U-Hub is an Ethernet to U-NET bridge equipped with analogue and AES3 digital audio transport. It facilitates
PC connection and VU-NET™ software control of MLA Series arrays and subwoofers via their inbuilt proprietary U-NET network.

Key Features

Ethernet to U-Net bridge

IP addressable (static and dynamic)

Analogue and digital audio transport

Designed to work with DX4.0 loudspeaker processor for Dante™ digital audio distribution

Converting TCP/IP to U-NET protocol, U-Hub allows MLA Series enclosures to self-address and identify their position within an
array, as well as supporting a simple-to-use redundant loop. With U-Hub, an MLA Series system with onboard U-NET can be
seamlessly integrated into a TCP/IP network and controlled via VU-NET software.
When used in conjunction with the Martin Audio DX4.0 networked system controller, U-Hub can connect audio and network to
an MLA Series system with a single cable via a Dante™ digital audio network.

U-Net Connections

The U-Hub features two U-Net ports and two pairs of parallel links to enable neatly loomed network cables to be used going to
and from several arrays. The U-Net connections are available on 8-pin ODU connectors. In common with standard Ethernet data,
U-Net only uses four of the available 8 pins allowing balanced analogue or AES audio to be fed down two or the 'spare' cores
thus greatly simplifying system wiring as an independent audio cable is no longer required.
