GUIDE TO INSTALLATION AND OPERATION
AAP-1741 | 23
Color samples – the three samples show the currently-selected color for the upper, middle and lower
zones of the meter.
Overload Counter
- The overload cursor appears on the meter as an arrowhead in the meter scale. The
two pulldown boxes set the position of the overload cursor on the left and right meters. If the audio level on
that channel goes above the cursor, the Overload Counter at the top of the meter is incremented. The
Reset Counter
box is available on the RALM - Connections tab.
Phasemeter
– this is a small meter that represents the phase correlation factor. Nominal position is in the
center, which indicates also the absence of signal. The red side, up to the left end of the meter indicates the
level of phase opposition and the green side, up to the right end indicates the level of phase amplitude.
3.3.7 A-BUS
The AAP-1741 can be used stand alone or as a
companion to provide additional audio channels
for other Densité cards. The A-BUS (audio bus)
links the AAP-1741 to the other cards and is used
to configure the system and to display the
presence of other installed cards.
A-BUS Config:
Select whether the A-BUS is to be disabled, and
whether this AAP-1741 is Master, Slave 1 or
Slave 2 in the A-BUS configuration.
• Not connected to Audio Bus – when the A-
BUS is disabled, it is not possible to detect
other attached cards in the system.
• Slave 1 of Video Card – used for a two-card
system when the other card is a video
processor.
• Slave 1 of Video Card, Slave 2 is present –
used for a three-card system, with a video
processor and another audio processor
configured as Slave2.
• Slave 2 of Video Card, Slave 1 is present –
used for a three-card system, with a video
processor and another audio processor
configured as Slave1.
• Master – the card is standalone, or used as a master for another audio processor configured as Slave.
This mode is not available when a video card is attached to the A-BUS.
• Slave of Audio Master Card – used for a two-card system when the other card is a audio processor
configured as Master.
Status:
• V Presence – turns green to monitor the presence of a video card in the A-BUS configuration.
• A2 Presence - monitors the presence of another audio card in the A-BUS configuration. The icon is
labeled A2 if this card is Slave1, and is labeled A1 if this card is Slave2.
