Introduction; Features
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 either via the front panel user interface,
Web application or ADP program.
Web App / Ethernet, USB and IR control
The AX
·
1250 amplifier is controlled, monitored
and programmed via Ethernet or the rear panel
USB.
An AX
·
1250 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,
On with Source Specific commands.
The Global commands also include PRESET1 –
PRESET 14, Alarm Enable, Alarm OFF, & 5
minute Sleep.
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.
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.
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 ADP program.
Real Time Clock
The AX
·
1250 amplifier is equipped with a real time
clock, and must have internet access to set
synchronize the time with an internet time server.
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.
Power Failure Restoration
After an AC power outage the AX
·
1250 amplifier
restores its settings to the pre-interrupted state.
All internal settings are stored in non-volatile
memory.
Restore Defaults
The AX
·
1250 amplifier may be readily set to the
default settings.
Restoring Defaults clears all memory and resets
the zone allocations to zones 1 – 8.
Setup Lockout
Locks access to the System Setup and More
menus where installation critical adjustments can
be made.
Password = 1396
Firmware Upgradable
The AX
·
1250 amplifier may be updated with the
latest operational firmware by either Internet
download or by using rear panel USB and ADP
program.
