RX series Power Amplifiers
Tour series of professional high power amplifiers
Park Audio™
RX series
RX series – is a tour grade series of professional four-channel high power amplifiers,which completely covers the needs of companies in the sound reinforcement equipment for large concert halls, stadiums and large outdoor areas.
RX series amplifiers are based on a modern, high performance D class topology. This topology provides high efficiency and low heat generation. Each pair of channels is powered by separate power supply.
The series includes RX9 amplifier with analog input unit and RX9d amplifier, which has both analog, and digital (AES) inputs. RX9d amplifiers is equipped with built-in DSP engine (DFM audio, Germany) and can be controlled via ETHERNET interface.
