Audio Engineering Axium AX-400DA Instruction Manual - page 7
Presets and Paging
There are 14 amplifier presets and two page
presets.
Presets 1 - 14 are momentary and cause the
amplifier to go to a predetermined setup, i.e.
standby, volume & source selection.
The presets may also be programmed with event
scheduling, and are used by the alarm clock.
The ‘Page Preset’ mode is for paging applications
and is invoked by a contact closure between the
0V and PG1 or PG2 terminals.
The contact closure must have an external power
source i.e. a 12 – 24V AC/DC powered door bell.
When the contact closure is released (power
sensed across PG – 0V terminals) the amplifier
zones return to their previous states.
PG1 is always assigned to the Page Preset.
PG2 may be assigned to any one of the 15
available Presets.
Zone Linking
A zone may be programmed to link multiple
zones. Zone linking ties the source selection
together. It may also tie the volume, and standby.
This is useful for closely coupled audio areas
where it is advantageous to have different volume
control but the same source, or the same volume
with separate standby control. Zone linking is
setup using the AMC program, or Web server
application.
96 Zones
There are 96 zones of possible control.
On a 400DAV amplifier each zone must be
different, however in a multiple amplifier stack
same zone amplifiers are possible – they simply
mimic every parameter.
Expansion Bus
Data, IR & Amp-On are interconnected via the
expansion bus.
One amplifier is connected to another using a
standard RJ45 patch cable. Connections are made
between amplifiers using either of the two RJ45
expansion bus sockets.
Door Bell
Up to 10 seconds of 44.1 KHz 16 Bit stereo
sounds may be generated as part of a page
preset. Suitable ‘wav’ files are uploaded to the
unit using the AMC program.
Amplifier ON Status – “Amp-On”
Each zone has AMP-ON status: 12VDC OUT on
the rear panel connector: (1, 2, 3, 4). The ‘AMP
ON’ output’s are protected against shorts.
Power Failure Restoration
After an AC power outage the 400DA amplifier
restores its settings to the pre-interrupted state.
All internal settings are stored in non-volatile
memory, except the clock that runs for at least 48
hours on stored power.
Restore Defaults
The 400DA amplifier may be readily set to the
default settings.
Restoring Defaults clears all memory and resets
the zone allocations to zones 1 – 4.
Setup Lockout
Locks access to the System Setup and More menus
where installation critical adjustments can be made.
Password = 1396
Firmware Upgradable
The 400DA amplifier may be updated with the
latest operational firmware, using the Axium
AMC program.
