Audiophony PA - Aio4500

The Aio4500 is a high-power 4 × 4 amplified matrix system designed to manage even large multi-zone installations. In a 2U rack format, it integrates a mixer, intelligent matrix routing, advanced DSP, and high-quality amplification. UMAC amplification technology ensures high performance with 4 × 500 W @ 4 ohms or 2 × 1000 W in bridge mode/100 V, maintaining extremely low harmonic distortion (THD+N < 0.05%) even under demanding conditions.

The DSP operates on three levels—input, zone, and output—allowing parametric equalization, compression, filters, delay, phase correction, and advanced management via importable FIR, with lockable presets to protect the system from tampering and ensure consistent performance over time.

Configuration is via an HTML5 interface accessible from any browser, without dedicated software, with routing, priority, custom mix, and zone limitations. Comprehensive connectivity: balanced/unbalanced inputs, S/PDIF, GPIO, Wi-Fi, and Ethernet, with compatibility with AioCTL wall controllers from the same brand for simple and intuitive control by users and staff.
