Sonata MADI Conversion Tools

Sonata MADI Converter Box

MADI Audio Converter Box

The Grass Valley™ Sonata breakout boxes carry 64 synchronous 24-bit digital audio channels on each coax cable and are optimized to work seamlessly with the Grass Valley Apex router providing distributed audio I/O and the Maestro master control system. They can also be used with audio consoles and in other MADI applications.

Key Features

Six conversion tools available:
- AES 75Ω to MADI
- AES/EBU 110Ω to MADI
- Analog to MADI
- MADI to AES 75Ω
- MADI to AES/EBU 110Ω
- MADI to analog
Supports 64 channels to/from MADI:
- Each model supports 64 channels of audio multiplexed to/from one MADI stream
Supports AES or analog inputs:
- 75Ω, 110Ω and analog I/O are all supported
Supports video reference timing:
- SD or HD rate, 50 or 59.94 rate video reference timing can be used
Interconnection with Apex and Maestro:
- Both Apex and Maestro have MADI input and output ports for audio
Interconnection with audio consoles:
- Most audio consoles support AES10 standard; the MADI standard over coax connections
Supports multiple signal sample rates
AES inputs ranging from 32 kHz to 96 kHz sampling can be received by Sonata and re-sampled to 48 kHz
