Power Amplifier Park Audio GS7

Park Audio GS7

The GS series is a touring series of professional high-power amplifiers that completely covers the needs for sound reinforcement equipment used for dubbing various events in large concert halls, stadiums and large open areas. The TD class circuitry used in the GS series amplifiers almost uncompromisingly combines the best features of key and analog amplifiers – the high efficiency of key amplifiers and the sound quality characteristic of analog amplifiers. Powering each of the amplifier channels from a separate power source ensures that operation can continue if one of them fails. The GS4, GS5, GS6, GS7 power amplifiers (GS – Series) are designed for sound signal high-fidelity amplification within professional sound reproduction systems. The amplifier’s schematics provides for high sound quality whether under low signal conditions or overload.
