2.6 Setup Menu
Options in the setup menu are:
•
Program Config
•
Operating Mode
•
Transport
•
System Settings
Press Enter to view the menu for the option on the second line of the display. The
Transport menu operates the time scaling function, and is described in Section
3.1, Transport Menu. The other three menus are described in this section.
2.6.1 Program Configuration
The Program Config menu initially displays the active program configuration.
Rotate the knob or press an arrow button to scroll through the other configuration
options. To process the input signal properly, the
Program Config setting must
match the configuration of the input signal.
The Program Config setting describes how the eight input channels are
configured. The notation conventions are as follows:
The + symbol separates individual audio programs within a configuration. For
example, 5.1 + 2 represents one 5.1-channel and one stereo program—which may
or may not be related. The × symbol shows the number of a given channel format
within that configuration. For example, 4 × 2 represents four two-channel
programs—again, which may or may not be related. One configuration has four
different programs:
4 + 2 + 2 × 1, which is one four-channel, one two-channel,
and two mono programs.
The Program Config parameter instructs Model 585 which input channels to
process together as a single, phase-coherent program. For example:
5.1 Processes the first six input channels as one complete 5.1-channel audio
program.
5.1 + 2 Processes the first six input channels as one complete 5.1-channel audio
program. Processes channels 7 and 8 as one complete stereo program.
4 × 2 Processes channel pairs 1/2, 3/4, 5/6, and 7/8 as four separate stereo
programs.
Model 585 processes all program configurations to the same high quality. Therefore,
there is no difference in audio performance between
2 + 2, 3 × 2, or 4 × 2
program configurations.
