Features
Thank you for purchasing an Axium AX-800DAV Multi-Zone Amplifier.
Please read this manual thoroughly before making connections and plugging in the unit.
Following the instructions in this manual will enable you to obtain optimum performance and
listening enjoyment from your new Multi-Zone Amplifier.
Please retain this manual for future reference.
Multi-Zone, Multi-Source, Video Switching
The 800DAV amplifier has six separate amplifiers
and two separate preamplifiers, providing 8 zones
of independent yet integrated control.
There are 11 inputs sources comprising the
following:
Sources 1 – 6 are either Analog Stereo, or Coax
Digital Audio (PCM).
Sources 7 & 8 are either Coax or Optical Digital
Audio (PCM)
Source 9 is either spawned from the USB Host, or
Ethernet
S10 is the Door-Bell .wav playback source -
typically used for paging applications.
The first 4 zones have a 4 source composite video
switcher, so monitor screens in four different
rooms may display any of the first 4 sources
(S1 – S4).
Preamplifiers and Outputs
Each zone has bass, treble, balance and loudness
control. These are accessed either from the front
panel or AMC
(Axium Music Centre) program.
A feature called ‘Maximum Volume limiting’, is
useful for protecting connected speakers. It may
be applied to both amplifier and preamplifier
outputs.
Amplifier Power, Protection, and Clipping
Indicators
50 Watts RMS per channel into 8 ohm loads.
Capable of driving into 4 ohm loads.
The amplifiers are protected against output
shorts, and have algorithms that prevent hard
clipping when the zone amplifiers are overdriven.
Thermal Control
There are two progressive levels of thermal
control:
•
The amplifier volume is reduced 20dB.
•
The amplifiers are shutdown until the
temperature reduces below the first level.
Care should be taken to ensure adequate
ventilation – see “Important safety instructions”

Ethernet, RS232, USB and IR control
The 800DAV amplifier may be controlled and
monitored via the rear Panel USB, RS232 serial
interface or Ethernet.
In multi amplifier installations where the
amplifiers are interconnected using an expansion
bus cable, only one Ethernet or RS232 connection
is required to control the stack of amplifiers.
An 800DAV amplifier may receive IR directly from
the front panel receiver or via the eight
‘Controller’ connections.
There are zone specific IR commands and also a
set of global IR commands.
The commands are: ON, OFF, Standby (toggling),
Mute, Volume Up, Volume Down, Source Selects,
Discrete Audio Source Selects, Discrete Video
Source Selects, On with Source Specific
commands.
The Global commands also include PRESET1 –
PRESET 14, Alarm Enable, Alarm OFF, & 5 minute
Sleep.
Real Time Clock
The 800DAV amplifier is equipped with a real time
clock.
The amplifier may be set up to function as an
alarm clock, so that at 6.30am in the morning 5
days a week, the master bedroom zone could be
made to turn on, select tuner, and go to a specific
volume. Multiple Alarms are feasible (max of 14)
however the Alarm Enable & OFF commands act
upon all programmed Alarms.
The Clock automatically compensates for daylight
saving.
The clock continues to operate typically > 48
hours without power – more than enough to keep
the time current during lengthy power outages
.
IR Emitter Ports
There are 10 Buffered IR emitter Ports.
Ports 1 – 8 have IR routing, and are intended to
control specific input source components. Two IR
ports 9 & 10 are the sum of all IR sources; these
control the ‘All’ zone source components.
