Connecting Digital Audio Components
Before making or changing the connections, switch off the power and disconnect the power cord from
the AC outlet.
Connect your digital components as shown below. The VSX-45TX has two coaxial and two optical inputs
for a total of four digital inputs on the rear panel plus one digital input on the front panel. In order to use
digital soundtracks like Dolby Digital or DTS (among others) you need to make digital audio connections.
You can do this by either a coaxial or an optical connection (you don’t need to do both). The quality of
these two types of connections is the same but since some digital components only have one type of
digital terminal, it is a matter of matching like with like (for example, the coaxial out from the component
to coaxial in on the receiver).
Hook up your digital equipment in accordance with this receiver's default settings (see next page) unless
you want to, or need to, change them. To do this see "Assigning the Digital Inputs" on page 91.
There are two optical digital out jacks (the CD recorder is connected to one in the diagram below). If you
connect this to the optical input on a digital recorder (currently these include MD, DAT and CD-R) you can
make direct digital recordings with this unit.
We also recommend hooking up your digital components to analog audio jacks (see page 20) in order to
make recordings (some digital sources may be protected against making digital copies).
