FX125.2

The Ashly FX125.2 is a compact, two-channel Class D power amplifier delivering 125 watts per channel, with integrated digital signal processing and network-based control. Designed for professional installation applications, it supports low-impedance loudspeakers and bridged 70V/100V distributed audio systems. Built-in Wi-Fi, Ethernet connectivity and browser-based configuration provide convenient access to its advanced audio processing, making it a versatile solution for commercial sound systems where performance, flexibility and compact dimensions matter.

From The Manufacturer:

The Ashly FX Series combines efficient Class D amplification with integrated DSP and network connectivity. The FX125.2 features two amplifier channels, dynamic power sharing and configurable low- or high-impedance operation. Its processing capabilities include equalisation, routing, compression, limiting, FIR filters, crossover functions, polarity and delay. Users can configure the amplifier through a web browser using its built-in wireless access point or a wired Ethernet connection.
