3.1 Operation mode options
Before making connections, decide how you want the sound
sources distributed throughout the site. This depends on whether
the area is specified for one or two zones, the kind of coverage
needed, and the sources to be used.
The mixer/amplifier provides three different modes of operation.
• Mixer Mode
In Mixer Mode, the system can mix up to four mic/line inputs to
each of the two output channels for use in one or two zones.
• Stereo Select Mode
In Stereo Select Mode, with up to two stereo sources
connected and using both output channels, the system
provides stereo sound to a single output zone. Refer to "Stereo
Select Mode" on page 9.
• Dual Mono Select Mode
In Dual Mono Select Mode, with up to two input sources
connected to each of the two output channels, the system
provides audio in two zones. Refer to "Dual Mono Select
Mode" on page 9.

3.1.1 Mixer Mode
Line-level sources can be connected using the RCA jacks or
Euroblock connectors. The system sums the two RCA jacks for
each input to mono.
Microphones must be connected using the Euroblock connec-
tors. Make sure the MIC/LINE switch is set to MIC.
Mixer mode sources can be routed to either or both outputs, as
shown below.
Sources can be independently routed to the auxiliary output.
In normal operation, the OUTPUT 1 and 2 gain controls are used
to control the gains of OUTPUT 1 and 2, respectively. In this
mode, you have the MASTERVOL LINKED option, which allows
you to configure the OUTPUT 1 gain control to control the gains
of OUTPUT 1 and 2 simultaneously.
Note: With use of a user interface, the chassis output gain knob is
disabled.
Use of one or two volume control user interfaces is optional. For
further detail, see "Mode user interface requirements" on
page 31.
