Section 1 — Introduction
Sonata AES-to-MADI Converters
The AES-to-MADI converters (both the 75M and 110M) have the following
features:
• Compact 1 RU box that converts 32 AES pairs to a single MADI output.
• Supports both 56 and 64 channel modes.
• Supports 75 ohm or 110 ohm versions of AES/EBU signals as specific
in AES3-2003 and AES3id-2001.
• Supports 48 kHz sample rate locked to 6 different video reference fre-
quencies & 44.1 kHz, 48 kHz, and 96 kHz locked to AES sync or Word-
Clock Reference.
• Full Sonata family reference section for maximum flexibility.
• Provides full-time sample-rate conversion for all inputs. All AES inputs
are sample-rate converted to the reference sample rate of 48 kHz. Can
be used to synchronize otherwise asynchronous audio sources.
• Full Dolby E support (will pass both Dolby E and Dolby Digital signals
automatically bypassing the sample-rate converters).
• Passes the entire AES signal complete with Status Block information for
complete data stream transparency.
• Provides dual MADI outputs for Redundant links.
• Fully Redundant power supplies and power connectors for on-air reli-
ability.
• Power alarms.
• Maestro Accessory providing 16 channel input expansion.
• Can be plugged directly into the Maestro Master Control Switcher
for Background sources A, B, C, & D.
• Can also be used to expand to 16 channels of Mix Over sources A,
B, C, & D.
• Apex Accessory provides input sample rate conversion from 32 to 96
kHz to the Apex router.
• Apex Accessory providing 32 AES pairs on a single coaxial cable to
reduce system wiring.
