DA8001 8 Channel Speaker Line Surveillance with Amplifier Fault Changeover
DSPPA Audio

The 8 channel amplifier fault auto-changeover with speaker line impedance surveillance is an integrated

controller integrates the amplifier fault changeover with the speaker line surveillance into one 19” 1U unit.

The amplifier fault auto changeover will automatically switch into standby amplifier once there is anyone of

the 8 amplifiers in case of fault. The switching time is within 1 second. The speaker line impedance

supervision enables to supervise the speaker line open circuit, short circuit and impedance fluctuation. Each

zone detection time is within 2 seconds. The amplifier fault and speaker line fault will be reminded by front

panel visualized indicator, buzzer and two RS485 interface to third party system.
