BBG-1002-2UDX PRODUCT MANUAL BBG-1002-2UDX-OM (V1.3)
Provides an audio crosspoint allowing the audio source
selection for each AES audio output channel. Also
provides Gain, Phase Invert, and Muting controls and
peak level meters for each output channel.
Note: •
AES Out Ch 2 has controls identical to the Source, Gain, Mute, and Invert controls described here for AES Out
Ch 1. Therefore, only the AES Out Ch 1 controls are shown here.
•
For each channel, its source and destination should be considered and appropriately set. Unused destination
channels should be set to the Silence selection.
• AES Output Channel Source Using the drop-down list, selects the audio input source to be embedded
in the corresponding embedded output channel from the following
choices:
• Card Audio Bus Ch 1 thru Ch 16 (Path 1 or 2)
• Built-in Tone generators Tone n
(-20 dBFS level tone generators with n being frequencies of 100, 200,
300, 400, 500, 600, 700, 800, 900, 1k, 2k, 4k, 6k, 8k, 12k, and 16k)
• Flex Bus A thru P mixer sum node outputs
• Audio LTC (Path1 or 2)
• Downmixer L (Path1 or 2)
• Downmixer R (Path1 or 2)
• Embedded Data L and R (Path 1 or 2) (SMPTE 337
non-PCM data embedding with option +ANC)
• Channel Mute/Phase Invert/Gain Controls
and Peak Level Display
Provides Mute and phase Invert channel controls, as well as peak level
meter for each output channel. (Meter shows level as affected by Level
control.)
Gain controls allow relative gain (in dB) control for the corresponding
destination AES output channel.
(-80 to +20 dB range in 1.0 dB steps; unity = 0 dB)
Note: Although the BBG-1002 can pass non-PCM data such as Dolby
®
E
or AC-3, setting the gain control to any setting other than default 0
will corrupt Dolby data.
