Fonestar PROX-240S

Fonestar PROX-240S - High-performance public address amplifier designed to meet the requirements of commercial and industrial audio installations. With a power of 240 W RMS, this model offers superior sound quality and reliability, making it ideal for use in spaces such as shops, conference rooms, restaurants, and other commercial locations. Its sleek and compact design allows for easy integration into any environment, and the 19" rack mounting facilitates installation in existing infrastructures.

The PROX-240S amplifier includes four input channels, three of which are dedicated to microphones and one for auxiliary signal, providing flexibility in connecting various audio sources. The microphone inputs are equipped with +48V phantom power, allowing the use of condenser microphones. Additionally, there are two auxiliary inputs (RCA and euroblock) for connecting other audio sources. The 100 V and 4 Ω outputs allow connection to a wide range of speakers, ensuring an even distribution of sound throughout the covered area.
