PreSonus I/O 4 overview

  • 1Description

The black I/O-4 Speaker System from PreSonus is a small format high performance sound reinforcement system, comprised of two speakers. The I/O-4 is designed for high quality foreground and background music applications for both indoor or outdoor applications. The I/O-4 utilizes a two element array of high output 4" woofers. The horn loaded high frequency wave guide is positioned between the two element arrays for coherent and balanced high frequency response. Polar lobing is controlled by this geometry and produces an aimed response at the crossover frequency. The system features a standard multi-tap transformer input that is switchable from a maximum of 50W of input power. The I/O-4 is equipped with a standard mounting bracket designed for flexible aiming and easy installation. The I/O-4 is ideal for use in restaurants, retail environments, bars, hotels, and more.
