SDP-40
UNDERSTANDING THE ZONES
The SDP-40 features three zones: the Main Zone, Zone 2, and the
Record Zone. The Main Zone is designed to
control audio and video signals in the primary listening space,
Zone 2 is designed to control audio signals in the secondary
listening space, and the Record Zone is designed to control audio
and video signals for recording devices. The Record Zone can also
function as a third zone, controlling audio and video signals in a
third listening space.
All three zones utilitize separate digital audio receivers, analog-to-
digital converters, and digital-to-analog converters. This allows
independent input selection in each zone with most input types.
For instance, the unit can play a DVD in the Main Zone, play a CD
in Zone 2, and send signals from a satellite receiver to a VCR
through the Record Zone - all at the same time.
The following exceptions apply to independent zone function:
• The same Dolby Digital or dts(-ES) input type can be
selected in all zones simultaneously. However, when a
Dolby Digital or dts(-ES) input type is active in the Main
Zone, a different Dolby Digital or dts(-ES) input type
cannot be active in Zone 2 or the Record Zone.
• Zone 2 and the Record Zone will provide a downmix (a
2-channel version of multi-channel digital audio) only
when using the same input that is selected in the Main
Zone.
• Use caution when switching from a Dolby Digital input
type to a dts(-ES) input type in the Record Zone. A loud,
brief noise may occur.
• Audio will mute for up to 2 seconds when:
- The same input is selected in the Main Zone that is
already selected in Zone 2 or the Record Zone.
Likewise, when the input is deselected in the Main
Zone.
- The same input is selected in Zone 2 or the Record
Zone that is already selected in the Main Zone.
Likewise, when the input is deselected in Zone 2 or the
Record Zone.
• When the 5.1 BYPASS listening mode is selected for the
Main Zone, the same input can be utilized by Zone 2 or
the Record Zone. However, only the FRONT L/R input
signals will be available.
