Application examples as an Analog-S/P DIF converter
The AC2496 reference level
should be set to match the
analog signal output level that
is connected.
If WORD clock cannot be in-
put, switch CLOCK SW to
"INT." The terminate switch
can be set to either position.
This switch will have no affect
at output of S/P DIF digital sig-
nals.
This is set to match the sampling fre-
quency of connected equipment.
For S/P DIF digital signals, it will comply
also to "96kHz."
• Connection example when substituting the input of personal computers (audio card)
An example using an AC2496 as an analog-S/P DIF converter connected to the audio card installed in a personal
computer for converting the analog audio signal to S/P DIF digital signal and recorded.
• Setup of the AC2496
When the AC2496 is to be used as an Analog-S/P DIF converter, it must be setup as explained below.
<Notes on setup>
When changing the select switches
of AC2496, be sure to do so only
after switching off power to
AC2496.
Should the switches be manipulated
with power on, it could create noise.

<Notes on cable connection>
When plugging or unplugging the interconnect-
ing cables be sure to do so only after switching
off the power to the AC2496.
Otherwise, noise could result.
Using the AC2496 as a digital master
In the explanations up to this point, the AC2496
was used as the slave. In other applications, the
AC2496 can be used as the master.
As shown in schematic at right, by applying
WORD clock from the AC2496 WORD OUT port
to digital equipment installed with WORD IN,
such equipment can be synchronized with the
AC2496 WORD clock.
<Note>
When using the AC2496 as the master, set its switch
to "INT" and the external digital equipment to "sync
mode."
