Description

Allen & Heath iLive MADI 64 - 64-Channel MADI I/O Module

The Allen & Heath iLive MADI 64 module is a professional-grade solution for audio engineers seeking to integrate their iLive and GLD digital mixers with high-channel-count broadcast, recording, or live production systems. It enables 64-channel bidirectional digital audio transmission per stream, supporting versatile applications in OB vans, studios, or third-party console systems, with robust synchronization and redundancy features.

Features

Dual 64-Channel MADI Streams

• Supports two streams of 64-channel bidirectional audio (128 channels total).
• Operates at 24-bit/48 kHz, ensuring pristine audio quality.

Connectivity

• 5 BNC Ports:
  • 2 MADI links for audio transmission.
  • 1 configurable AUX BNC for mirrored output, daisy chaining, or word clock sync.
• Compatible with 75-ohm coaxial cables for reliable connections over long distances.

AUX BNC Configurations

1. Out 1 Mirror:
   Duplicates the MADI Link 1 output stream for splitting to multiple devices.
2. In 1 Thru:
   Passes the MADI Link 1 input stream for daisy chaining with reclocked and buffered signals, ensuring reliability.
3. Word Clock Modes:
   • Input: Accepts external clock synchronization.
   • Output: Provides word clock signals for connected systems.

Redundancy and Synchronization

• Automatic failover between MADI Link 1 and Link 2 in redundant mode.
• Sync options include MADI Link 1, Link 2, and Word Clock (via AUX).
• Wide sync range: ±100 ppm at 48 kHz.

Multichannel Recording and Playback

Ideal for integrating with recording systems or feeding multichannel playback to live setups.
