Typical System Configuration
–
Continued
Fig 1 depicts a typical configuration where the 800DAV amplifier is providing audio into six of the possible
eight listening zones. Only three of the Zones are depicted.
Each zone consists of a room with a pair of speakers and a suitable controller. Additionally a zone may have
monitors or TV screens. In Fig 1 two such screens are shown in the Gym and Lounge.
Each zone may be listening / watching any of the connected sources: Satellite, DVD, Tuner, Internet Radio,
Media server, CD etc.
Controllers
Each zone has a specific control requirement.
Choose controllers that best suit the application.
•
Zone 1 – The Gym: Keypad with IR receiver
•
Zone 2 – The Study: Keypad
•
Zone 3 – The Lounge: Tablet
The Axium Keypad’s may be plugged into any of the
eight Controller ports.
Source control IR emitters are plugged into the IR
Ports. There are ten IR ports: IR1 - IR8, and IR9 &
IR10.
IR 1 – RI8 route source specific IR signals from
connected controllers, while IR9 & IR10 output the
common IR or the sum of all received IR signals.
These Ports may be used for source equipment that
is common to all zones.
When controlling the 800DAV using an iPad or other
Web tablet, the 800DAV must be connected to a
WIFI enabled Ethernet router and the Web Tablet
browser must be directed to the 800DAV’s IP
Address. The 800DAV’s WEB application also
provides source control functionality.
The 800DAV can store and regenerate source
equipment IR commands.
The 800DAV can be directed to output the IR
commands to a specific IR output port as required.
This advanced feature is programmed using the
Axium Keypad manager program (AKM)
Speakers
Speakers in each zone are connected to the
amplifier by “Home Run” speaker cables.
Video Outputs
The composite video outputs are suitable for driving
ONE composite video display device. To avoid signal
degradation, home runs of appropriate 75
Ω
video
cable should be less than 100 meters.
Source Equipment
The 800DAV amplifier has six stereo RCA audio
inputs for connecting to source equipment. These
input channels also feature Coax Digital inputs.
If a signal is present on the Digital input it takes
precedence over the Analog input.
There are two additional Digital only input channels
featuring both coax and Optical inputs.
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 media server.
All eight zones may select the same source, in such
circumstances there is a possibility that all eight
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.
Preamplifier Zone Outputs
The preamplifier output zones are completely
independent of the Digital amplifier zones. These
can optionally be used for locations where a high or
lower power amplifier / speaker would be required.
A third party power amplifier is required to power
the Zone speakers.
Alternatively a preamplifier Zone may be Zone linked
to one of the Digital amplifier zones, and provide
line level outputs to the zones subwoofer. This is
what is shown in the Study, where the preamplifier
zone 7 provides the active subwoofers line level. In
this case Zone 7 must be Zone Linked to Zone 2 and
Zone linking options for Link Volume and Link
Standby have been selected.
