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.
