Aio4500

High-power 4×4 amplified audio matrix for multi-zone installations.
Take control of your audio environment with the Aio4500, the high-power amplified audio matrix that transforms multi-zone management into a seamless and intuitive experience. In a 2U 19″ rack-mount format, this device packs everything you need to create custom soundscapes in every space of your facility: professional mixing, intelligent matrix routing, advanced DSP processing, and powerful amplification. From performance venues to luxury hotels, from fine-dining restaurants to event spaces, the Aio4500 orchestrates your audio sources with the utmost sonic precision and uncompromising power.

Pascal Audio technology at the service of your sound.
The Aio4500 is powered by Pascal UMAC™ power modules developed in Denmark, recognized worldwide for their excellence in professional amplification. This Class D technology delivers 4x500W @ 4Ω or 2x1000W in 100V/Bridge mode, with exceptional energy efficiency and virtually no distortion (THD+N < 0.05%). The result? A clear, dynamic, and powerful sound, even under the most demanding conditions. The three-level DSP (input, zone, output) allows you to precisely shape the sound: parametric EQ, dynamic compression, delays, active filters, and phase correction. Lockable speaker presets ensure optimal performance in all circumstances, protecting your system while delivering professional-grade sound quality.

Easy installation, elegant control.
Set up your system in just a few minutes using the HTML5 web interface, accessible from any browser—no app to install. Matrix routing, source priority management, custom mix creation, zone-based restrictions: everything is just a click away. The comprehensive connectivity options (balanced/unbalanced inputs, S/PDIF for daisy-chaining, GPIO, Wi-Fi + Ethernet) ensure seamless integration into all your projects. The AioCTL wall-mounted controllers (optional) offer your clients and staff elegant and intuitive control: a backlit display, a clickable rotary knob, and essential functions (volume, source, mute).
