F4.4.6. Digital Soundtrack Input

Soundtrack Input
Figure 19 – Digital Soundtrack Input
None is use when the AP25 analog and digital input connectors are not used for the film
digital soundtrack.
Digital Channels 1->8 select this if the film digital soundtrack player is connected to the
AP25 Digital Input channels 1-8 connector.
Analog Channels 1->8 select this if the film digital soundtrack player is connected to the
AP25 Analog Input channels 1-8 connector.
When the Digital Channels input is used for the digital soundtrack you must make sure
that the Input Source selection is Digital Ch: 1->8 as shown in Figure 20 below. The
other options, Digital Ch: 1->16 or Digital Ch: 9->16, should not be used because it
eliminates the cross-fade function between digital and optical. Pressing the Digital Ch:
button repeatedly allows you to change the digital channel selection.
