POWER ACOUSTICS SONORISATION Impact Array 918

A "Line Array" Format Designed for Modern Dispersion in a Compact Setup

Inspired by the Line Array approach used in sound reinforcement to improve coverage and clarity, this system adopts a 2+1 configuration: a dedicated subwoofer and two compact satellites housing multiple drivers. The goal is simple: to offer more even dispersion than a traditional speaker while remaining portable and quick to set up for performances, events, and mobile sound reinforcement.

Who Is It For and What Are Its Uses? A Practical Solution for Performances and Hosting

This pack is aimed at users seeking a versatile and self-sufficient system: mobile DJs, small bands, schools, associations, events, conferences, and occasions requiring fast setup. The subwoofer delivers the low end, while the satellites handle mid and high frequencies, useful for maintaining vocal clarity and strong musical presence.

Thanks to separate volume controls (subwoofer, full system, multimedia player) and dedicated microphone inputs with echo management, the system suits both background playlists and microphone hosting without needing multiple devices.

Features and Controls: Audio Settings, Multimedia Playback, and Stage Connectivity

Bass Management, Protection, and Room Adaptation

The system includes a limiter to control peaks and ensure safe operation at high levels. The adjustable crossover (40Hz to 160Hz) allows tuning the transition between subwoofer and satellites depending on the style (bass-heavy music, vocals, ambiance) and room acoustics. The subwoofer phase adjustment (0 degrees/180 degrees) helps optimize bass impact and coherence, especially when the subwoofer's position varies.

Dispersion Modes and Simple Mixing

The Mono/Stereo button facilitates integration based on your source and dispersion setup. For output management, the Mix Out outputs enable sending a signal to another system or additional zone. The left and right satellite outputs use 6.35mm Jack connectors to link the pack's dispersion elements.

Integrated Multimedia Player: Essentials Without External Devices

The built-in player supports MP3 playback and media via USB and SD, plus Bluetooth. The TWS function is designed for compatible wireless use, simplifying setups when you want to reduce cables on the source side. On the input side, RCA and a 3.5mm stereo AUX input provide direct connections for computers, smartphones, controllers, or audio players.
