APPLICATIONS & SYSTEM DESIGN CONSIDERATIONS
Creating a Low-Cost Second Zone
Using a Dedicated Source
The main problem in a single zone system is that when a source is being listened to
in one room, you cannot listen to another source in another room simultaneously.
However, for a listener who only listens to CDs, a low-cost second zone may be cre-
ated to allow simultaneous CD listening while the main system is playing another
source. This is possible only if the CD player you are using has dual audio outputs,
one with remote controllable volume and the other a fixed volume. As shown in
Figure 5, you connect the CD player’s variable output to the SI-1260’s dedicated
channel inputs for the particular room where you will listen only to CDs. The fixed
output is connected to the main preamp or receiver so you can also listen to CDs in
the rest of the house. The finishing touch is to install a Niles infrared repeater system
(IRR-4D, IRP-2+ and IRC-2) so you may adjust the CD player’s volume via remote
control from your CD listening room.
