Presets and Paging
There are six amplifi er presets and a page preset.
Presets 1 - 6 cause the amplifi er 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 the
‘PG’ terminals. When the contact closure is released the
amplifi er zones return to their previous states.
Zone Linking
A zone may be programmed to link one other zone.
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
or by the MC program.
32 Zones
There are 32 zones of possible control.
On a 450 series amplifi er each zone must be different,
however in a multiple amplifi er stack same zone
amplifi ers are possible – they simply mimic every
parameter.
Expansion Bus
Data, IR, Amp-On & Audio sources are interconnected
via the expansion bus.
The expansion bus feature vastly simplifi es the
installation cabling of an amplifi er stack.
One amplifi er is connected to another using a 34-way
ribbon cable. Connections are made from the output of
the fi rst amplifi er to the input of the second etc.
All audio sources must be connected to the fi rst
amplifi er.
Note: Video signals are not passed through the
expansion bus.
Door Bell
Looped 1.5 second mono sounds can be generated as
part of a page preset.
Suitable ‘wav’ fi les are uploaded to the unit using the
MC program. MC truncates the ‘wav’ fi les to a suitable
size.
Buffered Video Outputs
The composite video inputs are buffered for the purpose
of expanding to other amplifi ers in the installation.
12VDC 1A Power
Two 12VDC jacks are available for powering external
accessories.
Discrete Video and Audio Selection
The Video and Audio selection may be independent.
There are RS232 and IR Discrete control commands
available.
Amplifi er ON Status – “Amp-On”
Each zone has front panel ON status indication, and
12VDC OUT on the rear panel connector:
(1, 2, 3, 4 & #). The # ‘AMP ON’ output is a logic ‘Or’
output, i.e. if any zone is ON then the output will be 12V.
This is useful for driving a relay that connects AC power
to source equipment. The ‘AMP ON’ output’s are protected
against shorts. The ‘AMP ON’ outputs default to tracking
the preamplifi er ON status, but may optionally be set to
track the amplifi er ON status using the MC program.
Power Failure Restoration
After an AC power outage the 450 series amplifi er
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 450 series amplifi er 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.

Firmware Upgradable
The 450 series amplifi ers may be updated with the latest
operational fi rmware, using the
USB Uploader program. Provides a degree of future
proofi ng, and fl exibility.
