PROEL Session 1 Kolonn PA-system

Portable Column PA System for Mobile Sound

Delivering full-range sound from a single, easily carried load, the PROEL Session 1 is a powered column array designed to replace traditional two-box PA setups for small-to-medium venues. Built around an 8-inch subwoofer base and a three-section column housing four 2.5-inch high-definition drivers, the system produces 108 dB maximum SPL across a 50 Hz to 18 kHz frequency range. Amplification, mixing, media playback, and effects are all combined into one enclosure, so outboard processors or a separate mixer are unnecessary for compact venues.

Built-In Bluetooth with True Wireless Stereo Linking

Standing apart from competing portable arrays, this column system includes TWS (True Wireless Stereo) within the Bluetooth media player. Pairing two units enables one to transmit the left channel and the other the right, creating authentic stereo separation from a wireless source—a rarity at this price level. Musicians benefit from the 3-channel mixer that offers two XLR/jack mic/line inputs plus stereo mini-jack, each with its own level control. The echo-delay effect provides spaciousness for vocals or acoustic instruments without the need for external racks.

Loudspeaker Performance and Coverage

With its 90° horizontal by 60° vertical coverage pattern, the Session 1 fills a room evenly, avoiding hot spots. The four 66 mm full-range drivers handle mid and high frequencies with precision, while a 200 mm long-excursion woofer and 38 mm voice coil anchor the low frequencies.

• Maximum SPL: 108 dB — suited for live bands, DJ sets, and public speaking for up to 150 listeners in a room.
• Frequency Response: 50 Hz – 18 kHz — delivers a broad sonic range, deep enough for music playback without needing an extra sub.
• Coverage for both seated and standing audiences stays consistent thanks to the wide horizontal pattern (90° H × 60° V).

Amplification, Mixing, and Media Playback

Power is delivered via a 200 W continuous / 400 W peak Class D amplifier with a switch-mode power supply, driving both the subwoofer and the column drivers. Active filtering and dual clip limiters offer protection during prolonged high-level operation.

• Amplifier Power: 400 W peak / 200 W continuous — Class D technology minimizes weight and heat, while still providing ample dynamic headroom.
• Mixer Inputs: 2 × MIC/LINE (XLR + 6.35 mm jack), 1 × stereo line (3.5 mm) — perfect for two presenters or a vocalist with an instrument simultaneously.
• Media Player: USB / SD / Bluetooth with LCD display — supports playback from MP3 sticks, SD cards, or streaming from phones and tablets.
• Adding ambience is easy with the built-in echo-delay effect—no need for external pedals or racks.

Portability, Build, and Setup

The entire system weighs only 14 kg and is transported by a single handle on top of the subwoofer. A fast-linking system with integrated power contacts lets you stack the three column sections without speaker cables. Each column segment measures 520 × 84 × 97.5 mm, and the subwoofer is 318 × 400 × 484.5 mm—compact enough for any car boot. Polypropylene cabinets stand up to knocks and moisture. A padded bag is included for transporting the column sections safely.

• System Weight: 14 kg — single-person carry from vehicle to stage.
• Subwoofer Dimensions: 318 × 400 × 484.5 mm — fits easily into tight spaces at venues or on stage.
• Durable polypropylene construction resists impact and weather, making it suitable for outdoor events or mobile use.

Who Is the Session 1 For

Mobile DJs, solo performers, acoustic duos, and public speakers who demand a true one-trip PA system will appreciate the dimensions and weight of this model. Bluetooth and media-player features are advantageous for wedding MCs, business presenters, and fitness instructors needing to play backing tracks without a laptop. For users who want a self-contained, quick-deploy column system for both music and speech—without external gear—the Session 1 is a practical solution.
