Audiophony Aio4500 High-Power Multi-Zone DSP Amplifier

Description

The AUDIOPHONY PA Aio4500 is a high-power multi-zone DSP amplifier designed for demanding professional audio installations requiring flexible routing, advanced processing, and substantial output power. With four 500W amplifier channels, a 4x4 audio matrix, and bridge mode capability up to 2 x 1000W, it is ideal for performance venues, large terraces, nightclubs, hospitality spaces, and larger commercial audio systems.

Built into a 2U 19-inch rack format, the Aio4500 combines mixing, DSP, matrix routing, and Class D amplification in one integrated unit. Pascal UMAC™ amplifier modules deliver efficient and reliable high-power performance, while the built-in DSP provides detailed control across input, zone, and output stages.

Configuration and management are handled through an intuitive HTML5 web interface via WiFi or Ethernet, with further integration available through AioCTL compatibility and GPIO connectivity. With flexible analogue and digital inputs, parametric EQ, crossover, compression, limiters, and FIR filtering, the Aio4500 provides a scalable solution for powerful multi-zone installed audio systems.
