Aio4125

All-in-one 4×4 amplified audio matrix for multi-zone installations.
Take control of your sound environment with the Aio4125, the amplified audio matrix that transforms multi-zone management into a seamless and intuitive experience. In a compact 1U half-rack format, this device packs everything you need to create custom soundscapes in every space of your establishment: professional mixing, intelligent matrix routing, advanced DSP processing, and power amplification. From a cozy bar to a lively patio, from the dining room to the lounge area, the Aio4125 orchestrates your audio sources with the utmost sonic precision.

Pascal Audio technology at the service of your sound.
The Aio4125 is powered by Pascal UMAC™ power modules developed in Denmark, recognized worldwide for their excellence in professional amplification. This Class D technology delivers 4x125W @ 4Ω or 2x250W in 100V/Bridge mode, with exceptional energy efficiency and virtually no distortion (THD+N < 0.05%). The result? A clear, dynamic, and punchy 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).
