Standby Amplifier Changeover Unit
AX3800
8 duty / 1 standby Auto Amplifier Changeover Unit
Highlights
8 duty / 1 standby, Cascade to enable 16 duty / 1 standby
Priority changeover and overloading protection of standby amplifier
RS485 and dry contact for external monitoring
AX3800 is 8 duty / 1 standby auto changeover unit , providing a switching platform for standby unit to replace the position of failed duty amplifier. Should one standby unit is required to serve more than 8 power packs, more than one AX3800 can be cascaded.
It provides switching both at input and output section, thus suitable for matrix system where all amplifiers has different input sources. Detection is via 20 KHz, which is inaudible to human ears.
While it is compatible for most makes of amplifiers, please check the specifications of the amplifiers as they may have high frequency cut off, which would make the overall changeover functions unstable.
