SECTION 3 -
Typical System Configuration
FIG 1 depicts a typical configuration where the AX
·
1250 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.
Each zone may be listening to any of the connected sources: Blu-ray, Tuner, Media server, CD changer 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 AX
·
1250 using an iPad or
Android tablet, the AX
·
1250 must be connected to a
WIFI enabled Ethernet router and the Web Tablet
browser must be directed to the AX
·
1250’s IP
Address. The AX
·
1250’s WEB application also
provides source control functionality.
The AX
·
1250 can store and regenerate source
equipment IR commands, and be directed to output
the IR commands to a specific IR output port as
required. This advanced feature is programmed
using the Axium Design Portal program (ADP)
Speakers
Speakers in each zone are connected to the
amplifier by “Home Run” speaker cables.
Source Equipment
The AX
·
1250 amplifier has eight 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 four 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 to the
Tuner 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 preamplifier Zone may be Zone linked to one of
the Digital amplifier zones and provide line level
outputs to a 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. The zone 7 EQ must have a low
pass filter frequency selected.
