Feature

• • 2U chassis design, high integrated, modularization.Support speaker circuit grounding, open circuit and short circuit detection.
  • Support 3/4 wire horn circuit wiring.
  • 8 programmable trigger input interfaces.
  • 8 programmable trigger output interfaces.
  • Support power-saving mode when the amplifier has not input signal enters.
  • Support lines redundance wiring.
  • Support linkage to fire alarm controller.
• * Main amplifier automatic backup switching power amplifier, real-time detection, indicate by different color LEDs.
• * Real time monitoring speaker bus loop, power amplifier status, automatic control switch.
• * Allows amplifier enter into power saving mode when no signal input to save energy (start through VA-6000ST, default disabled).
• * Allows to configure the priority of network and local audio.
• * Support power through, even if the main and standby power supply is cut off at the same time (amplifier power supply normal), the local 8 audio signals are not affected.
• * 8 stem node or wet node input port, to trigger the pre-pragrammed language information to the specified zones or open the coresposing external power to the corresponding event warning.
• * 8 programmable relay signal output port, ouupt no voltage output short circuit relay control signal to the third party equipment to realize on-line automatic control.
• * Provide DC 24V standby power input interface ( connect to 24V DC supplied by VA-6000BC).
