*Word Clock, video; AES sync, S/PDIF sync; AES Audio, S/PDIF Audio. Both connectors tied together
(loop through) Unused connector should be terminated.
Viewing the rear panel of the AD-1000, the female XLR connector on the left is the left (or Channel A) analog
audio input. The XLR on the right is the right (or Channel B) analog audio input. (These are labeled "A" on the
diagram above.) The AD-1000 is set up for the worldwide standard pin 2 hot as shipped. A positive-going volt-
age into pin 2 will produce a digital audio output of the correct polarity.
Note that some equipment, especially in the USA, remains pin 3 hot. The AD-1000 can be configured for pin 3
hot. This is done by changing the position of switch 5 to of the eight pin DIP switch package located on the top
of the AD-1000. ON corresponds to Pin 3 hot and OFF to Pin 2 hot. The Red Pin 3 LED on the front panel will
illuminate to warn of the non-standard configuration.

Digital Outputs

The AD-1000 takes in analog audio and outputs digital audio in three formats as standard. The output format
is selected on the front panel power switch (additional formats are optional)
a) AES/EBU for professional applications (NORM Position)
b) S/PDIF for consumer applications (Both coaxial and optical) (NORM position)
c) Alesis ADAT for use with ADAT Optical Digital Formats (ADAT Position)
The AD-1000 simultaneously outputs a professional format digital audio output on the AES/EBU Male XLR con-
nector (D) and S/PDIF format in optical (F) and coaxial (B) formats. The coaxial consumer output (S/PDIF) is avail-
able on the 15 pin HD connector (E) on the rear panel via an adapter cable. Diagrams providing additional infor-
mation on these cables are located on pages 44 and 45.
Balanced and unbalanced word clock outputs are also available on the rear panel 15 pin HD connector. These
outputs can be used to synchronize a wide variety of other digital audio products (see pages 44–45).
