INTRODUCTION
Thank you for having chosen a PROEL product.
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.
INSTRUCTIONS ( FIG. 1 / 2 )
1. LEFT / CH1 - MIC / LINE IN (combo XLR-JACK input)
This is a female combo connector, which accepts a XLR or a JACK plug from almost any type of equipment with a
balanced or unbalanced outputs. The XLR input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
The JACK input is wired as follows:
Tip = + positive or "hot"
Ring = - negative or "cold"
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Pin 2 / Tip = + positive or "hot"
Pin 1-3 / Sleeve = shield or ground
NOTE: whenever possible, use always balanced cables. Unbalanced lines may also be used but may result in noise over
long cable runs. In any case, avoid using a balanced cable for one channel and an unbalanced one for the other.
In STEREO mode it works as the LINE input of the system's LEFT CHANNEL.
In DUAL and MONO mode it works as CH1 input, that is summed to CH2 input and sent to both amplifier's channels.
In DUAL and MONO modes only, the input sensitivity can be selected from the DSP display (page 2/9) as LINE, MIC or
MIC-20. The system's overall level can also be adjusted using the LEVEL control in the DSP main page.
In DOUBLE mode it works as the only LINE input for the system.
2. RIGHT / CH2 - MIC / LINE IN (combo XLR-JACK input)
Same as previous with the following differences:
In STEREO mode it works as LINE input of RIGHT CHANNEL.
In DOUBLE mode it is DISABLED.
3. LEFT / CH1 LINK (XLR output balanced)
This is a male XLR connector connected in parallel with the LEFT /CH1 input, so it is wired as the input.
In STEREO and DOUBLE modes it can be connected to the inputs of other powered speakers to obtain a more powerful
system.
We recommend to not use this connector in DUAL and MONO modes with MIC and MIC-20 input sensitivity.
4. RIGHT / CH2 LINK (XLR output balanced)
Same as above, connected in parallel with the RIGHT / CH2 input.
