AX3700 - 6 Duty / 1 Standby Automatic Amplifier Changeover Panel

Introduction

AX3700 offers a great flexibility and simplicity in cabling for auto amplifier fault changeover system with its combination of amplifier fault sensor modules and changeover panel in a box. The internally generated Pilot Tone and sensory circuit shall detect any faulty duty amplifier and would initiate a changeover process.

AX3700 has been optimized for faster fault detection and changeover as compared to AS4000. Pilot tones are generated at intervals to avoid constant loading of power amplifiers.

Changeover are performed at both input and output sections, making it suitable for application in a matrix system. At any one time, only a failed duty unit shall be replaced by a standby amplifier, to avoid overloading.

Features

• Cater for 6 duty and 1 standby amplifier
• Expandable for 1 standby to serve more than 6 duty units
• Built in Pilot Tone generator, transmit at intervals and senses at sequence to protect amplifiers
• Overload protection by allowing only a single take over
• Prioritized changeover - unit with higher number is preferred for changeover
• Shorter fault detection from 10 to 25 seconds
• Changeover at input and output sections 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
