Cadac CM-DT64 Dante network bridge and CM-MD64 MADI network bridge — MegaCOMMS audio network integration units

Audio Network Bridges

Overview

The Cadac CM-DT64 and CM-MD64 are audio network bridges that connect the CM-J50's MegaCOMMS network to industry-standard protocols — Dante/AES67 via the CM-DT64 and MADI via the CM-MD64.

Both support up to 64 bidirectional channels and include dual internal redundant PSUs.

CM Bridges

Introduction

Cadac network bridges enable simple, fuss free MegaCOMMS integration with other popular protocols, including MADI via the CM-MD64 Network Bridge, and Dante / AES67 via the CM-DT64 Network Bridge.

Both the CM-DT64 and the CM-MD64 support up to 64 bi-directional connections to map between MegaCOMMS ports and the relevant third party network.

Connection between the bridge and console is done via Cadac’s proprietary hi-speed data protocol - MegaCOMMS - which carries 128 channels of 24-bit, 96 kHz audio, plus control data and clock, bi-directionally, up to 150 metres via a pair of RG-6 coaxial cables.

CM-Network Bridges: Features

MegaCOMMS PORTS

Cadac network bridges MegaCOMMS BNC ports — red for receive, blue for transmit, with signal present LED indicators

There are two pairs of MegaCOMMS ports - on RG6 BNC connectors - carry all audio and control data between the control surface and other MegaCOMMS devices - stage racks or consoles.
Individual ports have a signal present LED.
The BNC ports glow red for receive (Rx) or blue for transmit (Tx), perfect for low light identification.

CM-DT64 DANTE PORTS

Cadac CM-DT64 Dante network bridge — primary and secondary Ethernet ports A and B for 64-channel Dante integration

Two Ethernet Dante network ports, A and B, are available to provide the required 64 input / output channel count.
Each has a primary and secondary connection; the secondary connections are for redundant network connections only.
Each A and B port has a connection OK LED.
IO FS LED indicates the sample rate (FS) of the inputs and outputs - 48 kHz or 96 kHz.

CM-MD64 MADI PORTS

Cadac CM-MD64 MADI network bridge — BNC and optical MADI ports for 64-channel AES10 compliant MADI integration

Two MADI network ports, 1 and 2, are available to provide the required 64 input / output channel count.
Ports are available with the option of BNC coax or optical connections.
The optical connection can carry the audio stream up to a distance of 2 km.
Each type of connector has a LED indicating successful receipt of data.
IO FS LED indicates the sample rate (FS) of the inputs and outputs - 48 kHz or 96 kHz.

WORD CLOCK

CM-MD64: Word Clock IN or OUT on BNC ensures the synchronisation of the digital signal with the network.
CM-DT64: Word Clock OUT only.
The Word Clock status LED indicates whether the unit is set to be Following an external clock, or whether the unit is set to be the Lead clock.
The Synchronisation LED indicates the unit is Following a Word Clock connected via the Word Clock IN BNC on the CM-MD64 , or is Following a Word Clock set by a third-party unit within the audio network, or the unit itself is the Lead Word Clock for both the CM-DT64 and CM-MD64.
