CHAPTER 2: HOOKUP

2.0 POWER

The AI-1 works with any AC voltage from 90 to 250 volts, 50 to 60
Hz. This eliminates the need for transformers or voltage switches.
The AI-1 comes with a line cord for the destination to which the AI-
1 is shipped.
The AI-1's IEC-spec AC cord (do not substitute any other AC cord)
is designed to feed an outlet that includes three pins, with the third,
round pin connected to ground. The ground connection is an
important safety feature designed to keep the chassis of electronic
devices such as the AI-1, BRC and ADAT at ground potential. Un-
fortunately, the presence of a third ground pin does not always
indicate that an outlet is properly grounded. Use an AC line tester to
determine this. If the outlet is not grounded, consult with a licensed
electrician. When AC currents are suspected of being highly
unstable in VAC and Hz, a professional power conditioner should
be used.

2.1 CONNECTION TO ADAT(S)

2.1A Single ADAT

To connect an Alesis AI-1 module, simply use two fiber optic cables
to connect the digital ins and outs back and forth between the AI-1
and the ADAT (see figure 1). It is not necessary to connect a sync
cable from the ADAT to the AI-1 (or vice-versa) since the ADAT will
provide the AI-1 with clock information via the optic digital
connection when outputting tracks to an AES/EBU or S/PDIF
destination, and the AI-1 will provide clock information to the
ADAT via the optic digital connection when recording from an
AES/EBU or S/PDIF source.
To connect the AI-1 to a single ADAT:
1. Connect one end of a fiber optic cable into the optic digital
output of the ADAT, and the other end to the AI-1's "ADAT"
