Typical System Confi guration – Continued
Fig 1 depicts a typical confi guration where the 450
series amplifi er is providing audio into four listening
zones.
Each zone consists of a room with a pair of speakers,
and a suitable controller. Additionally a zone may have
monitors or screens.
In Fig 1 three such screens are shown in the Lounge,
Gym and Bedroom. Each zone may be listening /
watching any of the connected sources: Satellite, DVD,
Video, Digital Music server, CD, or tuner.
Controllers
Each zone has a specifi c control requirement.
Choose controllers that best suit the application.
•
Zone 1 – The lounge: IR receiver
•
Zone 2 – The Study : Keypad
•
Zone 3 – The Gym : Keypad with IR receiver
•
Zone 4 – The Bedroom: Keypad with IR receiver
Source control IR emitters are plugged into the
IR OUTPUT ports.
There are two IR ports (IR1 + IR2) that combine control
from the BUS RUN 1 and BUS RUN 2 controller interface
ports. These outputs control source equipment available
to all zones, i.e. DVD, Video, CD and DMS.
Each controller interface has an associated IR out
port that routes IR only to that port. In Fig 1 the SAT
emitter is plugged into IR1 port, which means that SAT
control is only available to zone 1, 3 and 4 controllers.
The Tuner emitter is plugged into the IR2 port, so only
the zone 2 controller may control the Tuner.
Source Equipment
The 450 series amplifi er has one mono and seven stereo
RCA audio inputs for connecting to source equipment.
Fig 1 confi guration has only six of the possible eight
sources populated.
A zone may select from any of the connected sources.
Someone in the Lounge may be listening and viewing
the DVD, while another in the Study may be listening to
music from the Digital Music server.
All four zones may select the same source, in such
circumstances there is a possibility that all four zones
may be trying to control that source – not always
desirable – so a system should be well planned and
where appropriate additional source equipment
installed.
Speakers
Speakers in each zone are connected to the amplifi er by
“Home Run” speaker cables.
Fig 1 depicts a powered subwoofer in the study. The
subwoofer is driven by the zone 2 preamplifi er, and is
set to track the zone 2 amplifi er volume. The subwoofer
volume or offset can be adjusted for correct tonal
balance.
Fig 1 additional depicts a pair of speakers in the
bedroom. These are the associated Bedroom Bathroom
speakers and are driven by a low powered slave
amplifi er. The zone 4 preamplifi er has been set to
“Independent mode” and connects to the slave amplifi er.
Independent mode is where the preamplifi er volume
may be different from the amplifi er volume within a
34dB range or 68% of the volume level.
It also has independent standby and muting.
Video Outputs
The composite video outputs are suitable for driving
ONE composite video display device. To avoid signal
degradation, home runs of appropriate video cable
should be less than 100 meters (300ft).
