Allen & Heath AH-M-MADI2-A 64 X 64 MADI card 48kiloHertz (Requires DL-ADAPT-A for dLive and Avantis Use)

Audio engineers looking to add two streams of 64-channel bidirectional 24-bit / 48 kHz serial digital audio transmission to their iLive and GLD mixers will be impressed by the Allen & Heath iLive MADI 64, a MADI I/O module that allows for the connection and synchronization with broadcast or recording systems, OB vans, and 3rd-party consoles for high-channel-count feeds over coaxial cables.

The dual-port iLive MADI card supports two streams of 64-channel bidirectional 24-bit / 48 kHz serial digital audio transmission using two 75-ohm coaxial cables per port. An additional aux connector can be configured to mirror stream-1 outputs, pass thru stream-1 inputs, or as a wordclock input or output. Daisy-chain or split signals to multiple devices. Sync with either stream or an external word clock.

The second port can be configured as an independent stream or as a redundant backup connection using a second cable. Signals from either stream can be routed to the iLive channels in blocks of 8. iLive and GLD outputs can be patched to MADI and appear at both stream outputs.

Features:

• Dual Ports Support 2 Streams of Audio
• 2 x 64-Channel Bidirectional
• 24-bit / 48 kHz Operation
• Multichannel Recording/Playback
• Two MADI BNC Inputs and Outputs
• Additional AUX Output Configurable BNC
• AUX Mode: Out1 Mirror, In 1 Thru
• Aux Mode: Wordclock In, Wordclock Out

Specifications:

• Connectors: 5 x BNC (2 Links + Aux)
• Sample Rate: 48 kHz
• MADI:
  • 2 x MADI Input: Ultrahigh-Sensitivity Equalizing Receivers. 56 or 64 Channels (Auto Detect), 24-Bit (AC-coupled)
  • 3 x MADI Output: Standards Compliant, Low-Jitter Transmitters. 64 Channels, 24-Bit (Including Aux BNC)
• Aux:
  • Out 1 Mirror: Duplicates the Output Stream Appearing at the MADI LINK 1 Output. Useful for Splitting Signals to Multiple Devices
  • In 1 Thru: Duplicates the Input Stream Appearing at the MADI LINK 1 Input. Allows You to Daisy-Chain Signals to an Unlimited Number of Devices. The Signal is Fully Reclocked and Buffered for Optimal Reliability, and Will Automatically Switch to Link 2 if Link 1 Fails in Redundant Mode
