Audiophony Aio4125 Multi-Zone DSP Amplifier

Description

The AUDIOPHONY PA Aio4125 is a compact multi-zone DSP amplifier designed for professional installed audio systems requiring flexible routing, processing, and amplification from a single device. With four 125W amplifier channels, a 4x4 audio matrix, and switchable Lo-Z, Hi-Z, and bridge operation, it is ideal for public areas, commercial spaces, hospitality venues, retail environments, and multi-room installations.

Housed in a 1U half-rack 19-inch format, the Aio4125 integrates mixing, DSP, matrix control, and Class D amplification into a highly space-efficient unit. Pascal UMAC™ amplifier modules provide reliable performance, while advanced DSP processing allows detailed control across input, zone, and output stages.

The amplifier can be configured and managed through an intuitive HTML5 web interface via WiFi or Ethernet, with additional control available through AioCTL compatibility and GPIO connectivity. Its flexible input options, parametric EQ, crossover, compression, limiters, and FIR filtering make it a scalable solution for professional multi-zone audio distribution.
