Top Control Amplifiers

Powerful car audio performance with emphasis on sound quality aside of the motto “small is beautiful“ – the EMPHASER amplifier line up receives a program-update by the addition of two top control models, convincing with audiophile sound reproduction, but also with truly compact size and a user oriented set of features. The series consists of three models: the class A/B amps EA285 (2-channel) and EA485 (4-channel).
