Overview
The AD8 is an High-Resolution 8 channel Analog to Digital converter that features PEP technol-
ogy, a completely new look at digital audio for
music
.
The unit transmits the industry standard AES/EBU protocol on four XLR connectors. Both the
AES/EBU inputs (with AES input option installed) and AES/EBU outputs operate in single-
wire mode exclusively at all sampling frequencies. The AD8 can derive its sync source from an
Int
ernal reference, a

clock, a
S/Pdif
source (optical, or bnc), or
Option
ally an incoming
AES/EBU stream.
The AD8 has eight analog inputs that are floating and approximately 2.8k. Pin 1 of all of the
female XLR’s on the unit are internally tied to circuit common. This should be kept in mind
wiring systems together. The transformer coupled inputs can easily be interfaced with virtually
any studio interconnection scheme while providing isolation and superb common-mode rejec-
tion figures essential for hostile (nearly all) studio environments. The device is pin 2 positive
and although it is transformer coupled polarity should not be switched with unbalanced
sources by feeding pin 3.
There are a number of digital input and output options that are available for loop processing
that will be discussed in the Rear Panel section below.
