Names of Things and What They Do
1
AES/EBU input jacks A and B
These jacks are for input of AES/EBU-compliant digital audio. Use cables that meet
AES/EBU standards.
2
LOCK indicators A and B
These indicate whether the A and B inputs are correctly synchronized.
3
Sampling frequency indicators A and B
These display the sampling frequencies of the A and B inputs.

The SI-AES4 does not support
double-wire operation.
If a LOCK indicator flashes
and correct synchronization is
impossible, check the signal
format, sampling frequency,
and the like for the source
device.
If a LOCK indicator is unlit,
check for a broken cable and
make sure the output device is
working correctly.
The OTHER indicator lights up
when a digital signal at a
sampling frequency other than
44.1, 48, or 96 kHz is input.
When the sampling frequency
is 88.2 kHz, OTHER and 44.1
kHz both light up.
