Amplified 4×4 matrix system 125W 1U half-rack - AUDIOPHONY PA Aio4125

The Audiophony PA Aio4125 is an all-in-one 4 x 4 amplified matrix system for multi-zone installations. Its compact 1U half-rack format combines a mixer, intelligent matrix routing, advanced DSP and high-quality amplification based on Pascal UMAC Class-D modules. Output power is 4 x 125 W at 4 ohms, 2 x 250 W at 100 V or 2 x 250 W at 8 ohms in bridge mode. Total harmonic distortion plus noise is below 0.05% from 20 Hz to 20 kHz, while the signal-to-noise ratio exceeds 106 dB.

The DSP operates at input, zone and output level and provides 5- and 10-band parametric EQ, crossover, 512-tap FIR, compression, limiters, filters, delay and phase correction. Presets can be locked to protect the system from tampering and maintain consistent performance. Setup is performed from any browser through an HTML5 web interface, without dedicated software, with routing, priority management, custom mixes and zone limitations.

There are 4 analogue inputs, each offering balanced Euroblock and unbalanced RCA connections, with adjustable MIC, -10 dBu, +4 dBu or +14 dBu sensitivity. Connectivity includes 1 S/PDIF input and 1 output, 8-pin GPIO, Wi-Fi and Ethernet. Control is compatible with AioCTL wall controllers from the same brand, providing simple and intuitive operation for users and staff. The format is 19″ rack, 1U half-width, with a 100-240 V AC power supply and maximum consumption of 700 W. Applications include restaurants, lounges and venues with several sound environments, hotels, reception areas, meeting rooms, hospitality spaces, shops, showrooms, multi-zone commercial spaces, terraces, outdoor areas and distributed environments.

The package includes 2 mounting brackets, 1 x ½-rack AioR1 extension, power cable, 2 AioR1 half-rack mounting plates, 2 AioR2 rear brackets, Euroblock connectors, rubber feet and documentation. Dimensions are 22 x 4.45 x 31.9 cm and weight is 2.8 kg.
