A 4450 4 x 4 Audio Matrix/Switcher
®
1.0 INTRODUCTION
The A4450 master unit can be configured to operate as either a 4x4 Matrix, allowing any combination of inputs to be
selected to an output, or as a Switcher, enabling only one input to be selected to an output at any time. This is set by
the installer via a DIP switch on the rear panel. Note it cannot be configured to work as both. It is set as either a matrix, or
switcher. Any connected wallplates will automatically be set to suit the master unit.
Feature packed yet simple to set up and use, this mixer pairs with easy to use wallplate controllers. With 4 inputs selecta-
ble to up to 4 output zones it is ideally suited to gyms, cafes, restaurants, small clubs and function centres.
Designed with end users in mind, this complete audio source controller for buildings and venues provides source selection
and level control from remotely located wallplate controllers located up to 200m from the main unit. Multiple inputs can
be selected/mixed to an output zone as desired. The controller offers a visual indication of which input is selected to which
output on the front panel LCD and illuminated controls.
It accepts both balanced mic (pluggable screw terminals) and line level signals (stereo RCA) for four audio sources and
switches them to matching individual output zones. Any or all inputs can be switched to any and all output zones.
For added convenience all inputs and output zones can be labelled for display on the LCD. This allows users to quickly see
the source playing in each output zone.
A total of 8 remote wall plates and 2 paging consoles can be used on the system. Maximum of 2 plates per cable run (in
parallel or chained via extension connector on rear of plate). The A4660 paging console also includes the functionality of
a master control plate.
If required, the system can be controlled using standard RS-232 control codes for third party control systems.
