Audio Source Inputs
CD, TAPE, TUNER, AUX & Utility are common to all zones.
The utility input is mono and connects to both left and right channels. Typical applications are
paging, or where a mono source is required (AM radio)
Line Outputs
SOURCE SELECT is the Zone 1 pre-fader output - independent of the volume control.
A typical application for this output is where speakers have volume pads installed and a slave
amplifier is required to operate the network at full power.
PRE-OUT is the Zone 1 post fader output
–
Output level is dependant on the volume control.
The output is muted when Zone 1 is muted
.
PRE-OUT may be used to drive a high power Slave amplifier or Active Sub-Woofer.
IR Out
A 3.5mm phono socket provides direct connection for IR emitters. The output is individually
buffered and current limited, this ensures that a damaged emitter does not short out the IR
system.
Expansion Bus
Axium amplifiers may be connected together via a 20 way IDC ribbon cable connection.
This simplifies the Audio source component connections. – CD, TAPE, TUNER, AUX & Utility are
connected to only one Axium amplifier!
The summed Amp-On output, Axium Bus, and buffered IR input are linked through the Bus.
Axium Bus is a 2 wire serial communication interface which provides inter-amplifier and controller
monitoring and control.
