Stereo Zone w/ Multiple Sub-Zones

This application is ideal for large areas where independent volume control is needed in separate locations. Volume
is controlled in a variable zone using keypads, Olé Touchpads, IR sensors, or VIA! Touch Panels. Sources for the
entire zone are selected and controlled from this same keypad, touchpad, IR sensor, or touch panel.
Connect the speaker outputs of the S86A to a pair of speakers in the main zone. Volume in this area will ramp
up/down using IR or RS-232 commands from the zone's keypad, touchpad, IR sensor, or touch panel. Connect the
Zone Pre-Amp Outputs of the S86A to the inputs of an external amplifier. Connect the speaker outputs of the exter-
nal amp to two impedance matching volume controls, then to two pairs of speakers. Set the DIP switch for the zone
to FIXED. The volume controls will ramp volume up/down only for the speakers that they are connected to, giving
separate volume control in each areas of the zone. The volume up/down commands from the keypad, touchpad,
IR sensor, or touch panel will have no effect in the sub-zones. For mono sub-zones, use an RCA "Y" cable from the
Loop Output of the amplifier to an additional Zone Input of the amplifier. This application provides a stereo zone
(connected to the S86As built-in amp), a stereo sub-zone (connected to a pair of external amplifier channels) and a
mono sub-zone (connected to an additional channel of the external amplifier). If using electronic volume controls, a
hand-held IR remote control can be used for source select and control in the sub-zone areas. If using rotary volume
controls, all source selection and control must be done from the keypad, touchpad, IR sensor, or touch panel. This
application has cost-saving advantages. Only two pairs of amp channels are needed (one pair from the S86A's built-
in amp, and one pair from the external amplifier). Mono sub-zones require only one amplifier channel per sub-zone
area. If using electronic volume controls, independent volume up/down is available as well as source selection and
control. See Figure 2-5 for an example of a stereo zone/multiple sub-zone application.
