The balanced XLR (pin 1-ground; pin 2-hot;

@ INT/EXT (Word Clock Switch)
Used to switch
between
the internal
word clock
(44.1 kHz) or an external word clock
(through
BNC input).
The internal word clock is
assumed automatically
if no sampling clock
is
fed to the BNC input;
even
if this switch
is
on "EXT"
(external).
@ A IN/D IN (Analog/Digital Input
Selection Switch)
At "A IN", analog input is accepted,
and at "D
ІК", digital
input is accepted.
@ EXT. W. CLK (External Word Clock Connector)
This
terminal
can be connected with the word
clocks
(sampling clocks) of function genera-
tors and other digital
equipment
at the TTL
level.
The range of the frequency is from 30
kHz to 46.75 kHz (alializing distortion
results when analog input is selected rather
than digital
input with a sampling
frequency
of under 40 kHz).
In this case,
data such as
R/T,
Delay 1, is automatically
adjusted
to the
micro-computer.
(0 DIGITAL 1/0 (Connector for Digital
Input/Output)
This
is used when an optional
unit circuit
board
is mounted
for digital
input and output.
