DF-series
with DSP
DF DSP series amplifiers are designed for application in PA systems with high requirements for precise tuning of the parameters, but without the need for operative change.
The DF-series amplifiers have high efficiency class D topology with least heat and high sound quality, comparable with the best analogue amplifiers.
DSP accurately handles the audio signal thanks to its functions of equalization, filtering, delay, limiter and protection. DSP enables users to choose between eight preset settings.
