Typical System Configuration

– 

Continued

FIG 1 depicts a typical configuration where the 400DA amplifier is providing audio into three of the possible 

four listening zones.  

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: 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: Touch Panel Keypad 

•  Zone 3 – The Lounge: Tablet  

The Axium Keypad’s may be plugged into any of the 

four Controller ports. 

Source control IR emitters are plugged into the IR 

Ports. There are eight IR ports: IR1 – IR6, and SUM 

IR1 – IR6. 

IR1 – IR6 route source specific IR signals from 

connected controllers, while SUM IR1 – IR6 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 400DA using an iPad or other 

Web tablet, the 400DA must be connected to a WIFI 

enabled Ethernet router and the Web Tablet 

browser must be directed to the 400DA’s IP 

Address. The 400DA’s WEB application also provides 

Source control functionality.  

The 400DA can store and regenerate source 

equipment IR commands.  

The 400DA 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)  

Source Equipment  

The 400DA amplifier has three 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 three additional Coax Digital only input 

channels. 

A zone may select from any of the connected 

sources. Someone in the Lounge may be listening to 

the DVD, while another in the Study may be 

listening to music from the media 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 

amplifier by “Home Run” speaker cables.
