MADI
Allows MADI compliant audio data streams to interface with a DRS router
Overview
Multi-channel Audio Digital Interface, or MADI, defines a digital data multiplexing technology conforming to standards defined by AES10 1991 and AES10 2003. PESA’s Multi-Channel Audio Digital Interface (MADI) Adapter for DRS allows MADI compliant audio data streams to interface with a DRS router.
Available as an input or output device for DRS, MADI technology allows routing of up to 64 AES compliant audio channels over a single coaxial cable or fiber optic cable. Each MADI adapter is a stand-alone module that can support up to 2 separate 64-channel input or output MADI data streams. For installations requiring multiple modules a rack-mount frame is available. Each frame is one rack-unit (RU) in height and houses up to four individual MADI modules.
Features
- 128 I/O signals in a 1 RU frame
- Rack mount frame holds up to 4 modules in 1RU
- Scalable from 64X64 up to 2048X2048
- Supports standards for AES10-1991 and AES10-2003
- 2 separate 64 channel MADI data streams
- Allows simultaneous routing of AES and analog audio, embedded, MADI and time code signals
- Allows mix of synchronous and asynchronous signals
- RJ-45 connects modules to DXE or E-DXE audio processor frame
- Supports redundant control management

The Cheetah router can be integrated with the DRS Audio system allowing users the flexibility to route embedded AES or discrete audio with any SDI/HD-SDI video stream. With the DRS compact audio router system and Cheetah MUX/DEMUX modules, users have the ability to reduce overall cost and power consumption. With DRS integrated audio modules, any audio input can be embedded to any video output.
For installations requiring multiple MADI modules, PESA offers a rack mount kit that support up to 4 MADI input or output modules in a 1RU chassis frame. All connections are easily accessible from the rear, and all status LEDs are visible from the front of the frame. Power for all four modules is obtained from a single power supply integral to the rack mount kit. A redundant power option is also available.
