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.
