With this number of influential factors, there are a significant number of possible combinations.
A key element to multi-Aurora configurations is correctly setting the Unit ID switch on each LT-
MADI card.
7.4.1 Unit ID Switch
When multiple Auroras are daisy chained via MADI, it is essential that they each occupy unique
positions in the MADI stream. MADI is a serial medium, so devices in a MADI daisy chain will
be mounted in a sequential fashion. The Unit ID switch on each LT-MADI card determines the
order in which devices are integrated into the MADI stream.
The Unit ID is determined by the position of the SW1 and SW2 switch on the LT-MADI card. It
is possible to set this switch after the card is installed, although there should be no AC power to
the Aurora when this modification is made.
The unit ID should also correspond to the physical position of each unit in the daisy-chain. For
instance, the output of Unit 0 should connect to the input of Unit 1. The output of Unit 1 should
connect to the input of Unit 2, etc. For a system that is used in different settings, it is important
to make note of the device IDs for each Aurora so that they are not connected in the wrong order.
Switch 3 toggles the delay compensation on or off. Delay Compensation should be ON whenever
more than one Aurora is used in a MADI daisy-chain (see section 7.4.2), and OFF whenever a
single Aurora is used. The table below will describe the pertinent switch settings:
