Introducing the new generation of amplifiers from Amperes... QP2000 SERIES. Features offered surpassed the needs of most installation, as they are carefully designed by listening to the feedbacks from installers throughout the years and built according to the stringent requirements of users.

Available in various rating from 125W to 500W 100V line in compact 2 hu height, the new circuitry has been further enhanced, incorporating digital settings for tone preferences and other control features, higher efficiency, better frequency response and extra protection features. Each unit is addressable with RS485 output port. With monitoring software, the conditions and setting of the installed amplifiers can be conveniently monitored. Another distinguished feature is its built if AFS with Fault Changeover mechanism, thereby providing simpler interconnections for Automated Fault Changeover setup, and definitely lower BOQ.

QP series would definitely enhance your setup, providing years of reliable service and with Amperes' star rated service, you can be assured of getting the only right product in the market.
