Proel Session 4 is a compact and portable 2.1 system with 1200W of power configurable in stereo, Mono or Dual Mono, managed by a sophisticated DSP system. It includes two top modules and a subwoofer. Designed for musicians or solo singers, small live bands, mobile DJ setups, or for music and voice playback in corporate and even home applications, the SESSION4 combines flexibility, portability, and performance with a professional design and solid plywood construction.Each top includes four 2.75" neodymium speakers in a vertical array configuration, with a logarithmic arrangement and progressive downward tilt, to increase vertical coverage and provide precise sound anywhere in the listening area. The subwoofer features two 6.5" woofers in a band-pass configuration, capable of providing very powerful and dynamic lows, along with an extended low-frequency response.The system is powered by a 3-channel 1200 W Class D amplifier and is controlled by the powerful PROEL CORE LT DSP, capable of delivering excellent sound definition. Signal processing includes a sophisticated Dynamic EQ and 4 EQ PRESETS (MUSIC, LIVE, DJ, and SPEECH) to adapt the equipment to any type of application. The intuitive control interface features a single control knob and a large LCD screen, to control not only the DSP parameters but also the two selectable MIC / LINE inputs, the system configuration, and the built-in BLUETOOTH audio interface.The key features of SESSION4 are extreme flexibility and portability, making it one of the most advanced mobile column systems available. Thanks to a quick-link system with integrated connections, the two top modules can be combined together, forming a longer column of 8 speakers and allowing the system to be used not only in STEREO mode, but also in MONO or DUAL mode. Two dedicated compartments in the subwoofer itself allow the two top modules to be stored and transported in a single unit, reducing the space required for better mobility in line with the needs of today's musicians.
