Standby Amplifier Changeover Unit

AX3800
8 duty / 1 standby Auto Amplifier Changeover Unit

Amperes 8/1 Auto Amp Changeover Unit - AX3800
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.

Features
  • 8 duty / 1 standby setup 

  • Cascade feature available

  • Built in Pilot Tone transmitted at intervals to reduce amp loading

  • Overloading protections with single changeover

  • Prioritised changeover

  • Short detection from 7 to 15 seconds

  • Input and output section switching

  • Easier connections for links

  • Channel isolation for unused ports

  • RS485 data port
