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.
Benefits
Dual Link Mode: Connect and stream with two separate devices. Inputs to the system can be patched from the two MADI streams in blocks of 8, while the same outputs are broadcast on both links.
Redundant Mode: Link 1 and Link 2 can be used as a redundant pair. Audio and clock will continue if one of the cables fails.
Aux BNC:
- Out 1 mirror: This mode duplicates the MADI stream Out 1, useful for splitting signals to multiple devices.
- In 1 Thru: The MADI stream, In 1 is passed to the Thru ouput, allowing you to daisy-chain signals to an unlimited number of devices. The signal is fully reclocked and buffered for optimal reliability, and the signal will automatically switch to In 2 if In 1 fails in redundant mode.
- Wordclock In: Provides a wordclock input to sync the system from an external (48 kHz) source, for example a distributed word clock. This is a high-sensitivity input locking to a wordclock signal as low as 200 mV p-p.
- Wordclock Out: A standard wordclock output to allow other systems to sync from the iLive system, useful when connecting to 3rd party MADI devices, which may not be able to sync from the MADI stream.
Installation Compatibility
- Port B expansion slot in iLive fixed format MixRacks (iDR-16, iDR32, iDR-48&iDR-64) or expander (xDR-16).
- Port B and/or Port A of iLive modular MixRacks (iDR0, iDR10) if fitted with the RAB-2 standard.
- Port A of iLive modular Surfaces 80/112/144/176 if they are fitted with the new RAB-2 standard.
- I/O Module slot in GLD-80.
