FLEPCHER ACU9061 6 duty 1 standby auto amplifier changeover unit

The FLEPCHER's ACU-9061 automatic changeover unit provides monitoring and surveillance for your power amplifier units. It detects defects and provides automatic changeover capability for up to six amplifier units. This equipment ensures that a PA system's BGM or emergency message is aired continuously and without interruption.

It is suited for use in a matrix system since it performs changeover at both the input and output portions. To avoid overloading, only a failing duty unit should be replaced by a standby amplifier at any one moment. The ACU-9061's applications can be expanded to encompass more than 6 amplifiers at once when cascaded. A microcontroller-based signal processor is employed to implement individual input source and output detection, resulting in a more reliable changeover procedure.

• Cater for 6 duty amplifiers and 1 standby amplifier
• High sensitivity and accurate fault detection function, less than 2 seconds for changeover time
• Expandable for 1 standby to cater more than 6 duty amplifiers
• 6-channel audio source volume controls
• Built-in microcomputer detection system to realize auto amplifier fault changeover
• Overloading protection by allowing only a single take over
• LED indicator and switchable buzzer interface for fault alert
