MAESTRO Installation and Service Manual 55
Customer Requirements
Note A maximum of two direct Audio Mixer sources are supported in Maestro
whether or not the Audio Mixer MADI expansion is enabled.
For complete Sonata planning and installation information, please refer to
Sonata Series Planning and Installation Manual.
The MADI expansion discussion in this manual will focus on the Sonata
solution.
Interfacing to Maestro
The Sonata AES-to-MADI converters can be used with the Maestro master
control switcher for two primary purposes (
Figure 16 on page 56 ):
• Each MADI BNC input supports 64 audio channels (32 AES streams).
• The IN-1 MADI connection is an audio expansion to the four Maestro
background buses.
• The IN-2 MADI connection is an audio expansion to the four Maestro
Audio Mixers.
Maestro Background and Audio Mixer MADI expansion is enabled on a
per channel basis in the Channel Setup table.
Audio Input Expansion
The Maestro master control switcher maps the various channels of its
MADI inputs in a very specific order which is hard wired. As such, when
using the Sonata AES-to-MADI converter with the Maestro product the
inputs must be connected according to
Table 3 on page 59 and Table 4 on
page 60 . When less than the full 16 channels are used on a given Maestro
input, the unused channels are simply skipped and left empty.
