AC3801

8 Duty 1 Standby Manual Amp Changeover

AC3801 is a manual amplifier changeover unit that supports 8 duty and 1 standby amplifier with cascading, priority changeover, and AFS for uninterrupted audio operation.

Expandable to more than 8 duty amplifiers

Dual changeover (manual or automatic) with AFS-enabled amplifiers

Cascade function that support one standby amplifier

Power handling at 1000W per channel

Introduction

AC3801 is a manual amplifier changeover unit that ensures a standby amplifier takes over when a duty amplifier fails. It supports 8 duty amplifiers and 1 standby, with the option to cascade more than 9 duty amplifier units for larger setups. 


This model combines the features of its predecessors - AC3601 and AX700 - with priority changeover and increased input capacity. It allows manual switching from the front panel or automatic activation when paired with amplifiers with Auto Fault Sensing (AFS) amplifiers such as the QP or QP2000 series. AC3801 is ideal for continuous audio operation for commercial, industrial, and emergency applications.

Packing information

  • Carton size: 555 (L) x 295 (W) x 95 (H) mm

  • Gross weight: 2.55 kg

  • 1 unit(s) per carton
