When the Source is set to ADAT, the AI-1’s Destination Rate will
automatically be set to 48kHz, since this is the sample rate of ADAT.
If you wish to output the digital audio from the AI-1 at 44.1kHz,
press the 44.1kHz DESTINATION RATE button (its LED will be lit).
This can be used to route digital audio from ADAT to a DAT
recorder or CD recorder which uses the lower sampling rate.
3.2 USING THE BRC
The Alesis BRC Master Remote Control can be used to control all of
the AI-1’s functions. The BRC’s DIGITAL I/O button is used to
activate and deactivate the AI-1 functions. When the DIGITAL I/O
button is enabled, its LED will be lit and the current digital inputs
can be recorded to ADAT (the analog inputs will be ignored). The
type of digital input that is enabled by this button depends upon the
type of digital input that is selected when this function is edited.
If you access the BRC’s Edit mode (by pressing the EDIT button)
and select DIGITAL I/O, you can control the AI-1’s parameters
(Source, Destination, Destination Rate, and ADAT tracks to be sent
out of the AI-1). However, the DIGITAL I/O button must be
enabled for any changes you make to affect the AI-1. If you make
changes to the AI-1’s settings from the BRC while the DIGITAL I/O
button is off, the AI-1 will automatically be updated the next time
the DIGITAL I/O button is turned on, so that its setup concurs with
the BRC.
