High-power amplified 4×4 500W 2U matrix system - AUDIOPHONY PA Aio4500

The Audiophony PA Aio4500 is a high-power 4 × 4 amplified matrix system built to run large multi-zone installations. Housed in a 2U rack chassis, it combines a mixer, intelligent matrix routing, advanced DSP, and high-grade amplification.

UMAC technology delivers 4 × 500 W at 4 ohms, or 2 × 1000 W in bridge/100 V operation, with very low harmonic distortion (THD+N < 0.05%) even under heavy load. DSP runs at three tiers—input, zone, and output—with parametric EQ, compression, filters, delay, phase correction, and advanced control via importable FIR; lockable presets guard against tampering and keep performance stable over time.

Setup uses an HTML5 interface in any browser, with no dedicated software: routing, priorities, custom mixes, and per-zone limits. Connectivity covers balanced and unbalanced inputs, S/PDIF, GPIO, Wi‑Fi, and Ethernet; the unit works with Audiophony AioCTL wall controllers for straightforward operation by users and staff.

User-facing advantages include easier multi-zone control via 4 × 4 routing and HTML5 tools; three-level DSP with lockable presets; faster installation through browser configuration; AioCTL compatibility; reliability from Pascal UMAC modules; and balanced, S/PDIF, GPIO, Wi‑Fi, and Ethernet I/O.

Typical applications: restaurants, lounges, and venues with several sound zones; hotels, receptions, meeting rooms, and hospitality areas; shops, showrooms, and multi-zone retail; terraces, outdoor areas, and distributed high-power systems.
