FX125.8

The Ashly FX125.8 is an eight-channel Class D installation amplifier delivering 125 watts per channel, with integrated digital signal processing (DSP), network connectivity and flexible loudspeaker configurations. Designed for multi-zone commercial audio systems, it supports low-impedance loudspeakers and bridged 70V/100V distributed audio applications. Built-in Wi-Fi, Ethernet connectivity and browser-based control allow installers to configure audio routing, equalisation and speaker processing from a compatible device. Its eight amplifier channels and compact 1U rackmount design make it a versatile solution for installations requiring multiple independently controlled audio outputs.

From The Manufacturer:

The Ashly FX Series combines high-density Class D amplification with integrated DSP and network-based configuration. The FX125.8 provides eight low-impedance amplifier outputs or four bridged high-impedance outputs. Its processing platform includes input, zone, output and speaker processing, with functions such as parametric equalisation, crossover filters, compression, limiting, FIR filtering, polarity and delay. The browser-based interface is accessible over Ethernet or the built-in Wi-Fi access point, allowing the amplifier to operate as a compact amplification, mixing and processing solution for installed audio systems.
