many public address installations especially in a public address
matrix system set-up, the need to handle multiple paging zones are
unavoidable. The PC 406 4 x 60 W Audio Power Amplifier provides
the best solution to handle such an application.
PC 406 amplifier comprises 4 modular channels with each channel
handling up to 60 W rms output power. It utilises high efficiency
Toroidal Transformer Technology in its design; which reduces electromagnetic
built-in amplifier supervisory module in every channel provides
interface to the SA 05 Automatic Changeover Unit for switching over
the input and output of the faulty channel to a standby amplifier
when a fault is detected.
self diagnostic circuit is incorporated in each channel of the PC
406, to monitor its operations. To protect and ensure uninterrupted
operation of the unit, every individual channel will automatically
isolate itself from its load and a protection LED indicator will
activate once a fault is detected.
