A WORD SYNC – THRU (AUTO TERM)
This BNC connector echoes the word clock which is
input at the
WORD SYNC – IN connector 9 .
If no connection is made to this connector, it is auto-
matically terminated.
B WORD SYNC – OUT (STD Fs)
This BNC connector outputs a standard-frequency
word clock: either 44.1 kHz when
44.1k or 88.2k is
selected, or 48 kHz when 48k or 96k is selected.
C WORD SYNC – OUT (HI Fs)
This BNC connector outputs a high-frequency word
clock: either 88.2 kHz when
44.1k or 88.2k is
selected, or 96 kHz when 48k or 96k is selected.
NOTE
These clocks output from B and C may or may not
be the same as the clock received at WORD SYNC –
IN
9 and retransmitted through WORD SYNC –
THRU (AUTO TERM)
A
. However, they are always
the word clock selected using the CLOCK switch 3 .
D ~ IN (power in)
Use the supplied power cable to connect the IF-
AE8HR to the power supply. Always ensure that
your power supply matches the requirements marked
on the rear panel of the unit. If you are in any doubt,
consult a qualified electrician.
