8 Duty 1 Standby Auto AMP Changeover Panel (AC-5418) PA System

  • Cater for 8 duty and 1 standby 
  • Expandable for 1 standby to cater for more than 8 duty amps. 
  • Built in Pilot Tone generator, transmit at intervals and senses at sequence to protect amplifiers
  • Overloading protection by allowing only a single take over. 
  • Prioritised changeover which higher numbered amplifier shall be preferred for take over if more than two units are down
  • Changeover at input and output section simultaneously ; suitable for matrix system installations 
  • Input link switch ; making connection of sources easier. 
  • Channel isolation switch for unused or un-monitored channel. 
  • Individual channel status indicators ; normal, fault and changeover.
AX3800 offers great flexibility and simplicity for amplifier fault changeover setup. With the precise circuit design, amplifier fault detection period is greatly reduced to initiate timely changeover to standby unit. The internal pilot tone generation at 20KHz is set at optimum interval to avoid unnecessary loading to amplifiers.
Changeover shall occur at both input and output of amplifiers, making it suitable for application in a matrix system. Priority and single changeover ensures overloading of standby amplifier is avoided, thus providing a reliable and uninterrupted system at most times.
