MAESTRO — Installation and Service Manual 107
Summary of Installation Procedure
Maestro Preset bus. Transitions will occur within the Maestro Master
control itself.
Video : A maximum of 12 router outputs can be dedicated for connec-
tion to Maestro: four for use as background video, and 4 key signal
pairs. The background signals are named Background A, B, C, and D.
Inputs A, B and C are the primary background inputs and provide
video for the PGM, PST, and AUX busses. There is no one-to one-corre-
spondence between a particular input and a particular video bus.
Background D is for a video source with embedded audio for use in
audio/video breakaways with embedded audio. Each key signal pair
will consist of a key fill and a key cut. Any set of 12 router outputs can
be used since they are identified during software configuration and are
switched dynamically as needed.
Note For additional keyer wiring information, see Keyers on page 67 .
Audio : The audio inputs used are dependent upon the audio formats.
AES audio that is paired with background video uses the BG A In and
the BG B In inputs. Over A In and Over B In are used for AES audio
overs. Each input supports up to four AES pairs.
The AES-to-MADI conversion with the Sonata converters is needed to
supply up to 16 channels of audio for video Background A, B, C and D
and up to four audio over mixers. These converters use the MADI In 1
and MADI In 2 inputs.
Embedded audio uses no audio inputs as the audio is carried with the
video signal. If the rear panel is the 110 Ohm type (25-pin D connectors),
refer to the pinout table on
Table 8 on page 94 .
Note Up to 16 channels of audio per background video bus and audio over mixer
can be supplied by a 1RU Sonata MADI Converter. Audio for background
video buses and audio over mixers each require a separate Sonata converter
for a total of two Sonata converters per Maestro transmission channel for full
16-channel audio support.
b. Outputs
Video : Maestro has four video outputs: Program, Preview, Clean
Feed 1, and Clean Feed 2. Two copies of each signal are provided.
Clean Feed 1 has background video only (no key inserts); Clean
Feed 2 has background video plus any key signals inserted by the
upstream keyer (no downstream key material is shown).
AES Audio : The four audio outputs are: Program, Clean Feed 1,
Metering, and Monitoring. Each of these outputs consist of four
AES pairs.
The Monitoring outputs should be connected to the control room
speakers. The audio Monitor Out 1/2 connector provides left and
right stereo monitoring (see
Figure 51 on page 116 ). Monitor Out 1/
