PROEL Session 4

Compact Portable Array System 

SESSION4 is a compact portable array system in an active 2.1 configuration, 
including two tops and one subwoofer. Designed for solo performers, 
small live groups, 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 a sturdy plywood 
construction.
Each top includes four 2.75” neodymium drivers in vertical array configuration, 
featuring a logarithmic arrangement and a progressive down tilt, for increasing 
the vertical coverage and providing an accurate sound in any part of the 
listening area. The sub features two 6.5” woofers in band-pass configuration, 
able to provide very ‘punchy’ and dynamic basses, together with an extended 
low frequency response.
The system is powered by a 3-channel 1200W Class D amplifier and it’s controlled 
by the powerful PROEL CORE LT DSP, able to deliver an outstanding sound definition. 
The signal processing includes a sophisticated Dynamic EQ and 4 EQ PRESETS 
(MUSIC, LIVE, DJ, SPEECH) to adapt the speakers to any kind of application. 
The intuitive control interface features a single knob and a large LCD display, 
for controlling not only the DSP parameters but also the two MIC/LINE selectable 
inputs, the system’s configuration and the built-in BLUETOOTH audio interface.
The SESSION4 key features are extreme flexibility and portability, which make 
it one of the most advanced mobile column systems available. Thanks to a fast 
linking system with integrated connections, the two tops can be combined together, 
forming a longer 8-driver column and allowing the system to be used not only in 
STEREO mode, but also in MONO or DOUBLE mode. Two dedicated compartments in the 
sub’s cabinet allow the tops to be stored and transported in the unit itself, 
reducing the space requirement for a better mobility in line with the
needs of today’s musicians.
