Extension example after installing a Model 5045
The 8 analog-input channels of the AC2496 can be extended to 16 channels by installing an optional
Model 5045 8ch A/D card.  Such an installation enables 24 track simultaneous recording by using a
D2424 as shown in example below.
• Connecting example for 24 track simultaneous recording
This is an example of installing a Model 5045 in an AC2496.  Twenty four channels of analog signals can then be
recorded simultaneously.  In this example, analog signals (1-8) from analog mixer 1 are input to ANALOG INPUT
1-8, while signals from analog mixer 2/3 (1-8, 9-16) connected to the AC2496 are converted to adat digital
signals and applied to DATA INPUT 9-16 and 17-24.  Using this procedure, it is possible to simultaneously record
24 tracks.

• Setup of the AC2496
The same as the previous example, when using an AC2496 as an Analog-adat converter, it must be setup as
follows:
If WORD clock is input from a
D2424, the CLOCK SW must
be set to "WORD" and the ter-
minate SW to "ON."
If an 8 BUSS OUT mixer is to
be connected, set the ANA-
LOG INPUT MODE SW to "1-
8."
Set to "ADAT-48" or "ADAT-
44.1" to match the D2424
sampling frequency.
Set the AC2496 reference level
to match the output level (bal-
anced/unbalanced line) of ex-
ternal equipment connected
such as an analog mixer.
