AX3800 MK II
8 Duty 1 Standby Auto Amp Changeover
AX3800 MK II is an advanced amplifier changeover unit that supports 8 duty and 1 standby amplifier with cascading, priority changeover, pilot tone injection and remote monitoring. Suitable for large-scale installations.
Cascading support for up to 16 duty amplifiers and 1 standby
Dual changeover (manual or automatic) at input and output
RS485 port and dry contact for remote monitoring and integration
Faster fault detection and recovery within 7 to 15 seconds
Introduction
AX3800 MK II is an advanced amplifier changeover unit designed for seamless automatic switching at input and output in case of amplifier failure. This upgraded version features faster fault detection and channel recovery time, reduced noise, and improved pilot tone injection for enhanced performance. It supports cascading, allowing one standby amplifier to serve up to 16 duty units. The unit provides priority changeover to prevent overloading, generates 20kHz internal pilot tones to reduce amplifier workload, and includes a buzzer alarm for fault detection. Additionally, RS485 port enables remote monitoring for centralized system control. With dual changeover at both input signal and 100V output, the AC3800 MK II is ideal for matrix setups and large-scale installations requiring reliable audio continuity.
Note: AX3800 MK II is an upgraded version of the now discontinued AX3800 with all other features retained.
