The DVE option requires three background video sources (BGA, BGB, and
BGC).
The DVE option also requires at least one of the three background audio
sources:
• If the Maestro processor will use embedded audio, no additional hard-
ware is required for DVE operation.
• If the system includes a Grass Valley Apex audio router, no additional
hardware is required for DVE operation since Apex includes AES to
MADI conversion as a standard feature.
• If Maestro will use AES audio inputs and the Audio router is not an
Apex, an optional 1 RU AES to MADI Converter unit must be used to
provide the third background audio source. The planner should specify
“SON-AU2MADI” (Sonata AES 75 ohm unbalanced to MADI) or
“SON-AB2MADI” (Sonata AES 110 ohm balanced to MADI) units.
When these Sonata converters are installed, the corresponding AES
inputs on the Maestro rear panel are not used and audio for all back-
ground video sources (Bkgd A, Bkgd B, Bkgd C and Bkgd D) are wired
from the router to the Sonata converter. Background MADI Expansion
must be enabled in the Channel Setup section (8th Step: Channel Sets>
Channel Setup) for the respective channel installed in this manner.
