Block Diagram / Schematic
The block diagram shown is for the installer
to have a better understanding on how the
unit works when interfacing it with other
brands of PA equipment.
It is however not recommended that the
internal circuitry of the unit be modified
without prior consultation with the
manufacturer.
Thank you
for selecting another product from Amperes Electronics and we truly believe that by
incorporating AS4000 into your system, you would find them more than satisfactory in what you expected.
Introduction .....
Installing Amperes AS4000 together with Amperes AX700 ( Automatic Amplifier Changeover Unit )
shall establish an automatic amplifier line surveillance setup in your public address system.
AS4000 shall be connected to each power amplifier and shall monitor the line condition
continuously by injecting an inaudible frequency to the pack at repeated intervals. Failure to sense
the monitor signal in return shall confirm the failure of the power amplifier or if when the line out is
shorted. Upon detection of the failure, a dry contact shall be established to provide a signal to AX700,
which would then perform a standby changeover to the duty amplifier concerned.
AS4000 is designed with fine circuitry, is an ideal choice for an automatic surveillance installation
setup, made in modular form which proved to be cost effective.
