Amperes Class D Amplifiers with auto fault sensor (AFS)- QD2000 Series: QD2025/ 2050/ 2075/ 2100

Highlights

Amperes QD2000 Series of newly developed amplifiers are powered by Class D circuits for wider frequency response range and with higher energy efficiency. It is engineered through extensive research based on feedbacks from installers, thus able to offer a cost effective and reliable power packs.

​

It has built in auto fault sensor ( AFS ) circuit to monitor itself and a dry contact is available if the unit fails. RS485 data port is available and API can be requested to enable third party software developers to develop their own monitoring software.

​

Amperes QD2000 is suitable for most premium PA installations, be it centralized or decentralized network systems. 

RS485 output for remote monitoring

High efficiency and better frequency response with Class D amplifier

Auto Fault Sensor ( AFS ) with dry contact for changeover

Features

  • High efficiency Class D amplifiers

  • 100V and 4 Ohm outputs

  • High pass filter switch for speaker protection

  • Switchable standby power to reduce power consumption when no incoming signal is detected

  • Auto fault sensor ( AFS ), self diagnose for faulty unit

  • Remote monitoring via RS485

  • AC and DC back up for uninterrupted operations
