SUMMARY OF FEATURES
Cater for 6 duty and 1 standby and expandable to allow a standby pack to serve larger quantity of duty
amplifiers
Built in Pilot Tone generator which transmit at interval and senses at sequence to protect the power
amplifiers
Overloading protection by allowing only a single take over
Prioritised changeover which higher numbered amplifier shall be preferred for take over in the event
more than two units are down
Shorter fault detection time from 10 to 25 seconds
Changeover at input and output section simultaneously ; thus suitable for matrix system installations or
uninterrupted paging setup.
Input link switch ; making connection of sources easier than hardwired loopings which would make
interconnections look less messy.
Channel isolation switch for unused or unmonitored channels
Individual channel status indicators ; normal, fault and changeover
