CHAPTER 2: HOOKUP

2.0 POWER

The BRC works with any AC voltage from 90 to 250 volts, 50 to 60 Hz.
This eliminates the need for transformers or voltage switches. The
BRC comes with a line cord for the destination to which the BRC is
shipped.
The BRC'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 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 SYNCHRONIZING MULTIPLE
ADATS

2.1A Hooking Up Multiple ADATs

Synchronization requires a dual male, 9-pin D connector to connect
the BRC to the first ADAT in your system, and an additional dual
male, 9 pin D connector for each additional ADAT to be
synchronized. This connection can be made while power is on or off,
and the ADATs do not need to be turned on in any particular order
(see figure 1). The maximum cable length allowed is 50 feet, between
the BRC and the first ADAT in the system.
1. Connect one end of the cable to the BRC's sync out jack;
2. Connect the other end of the cable to the sync in jack of the first
ADAT in the system (this unit will serve as tracks 1–8);
3. For each additional ADAT slave, connect one end of an additional
dual male, 9-pin D connector to the first ADAT slave's sync out
jack, and the other end to the second ADAT slave's sync in jack. Its
sync out jack then connects to the third ADAT slave's sync in jack,
and so on;
Note: In a multiple ADAT system, if power is turned off on one of
