Description
The FXD125.4 is a networked installation amplifier that combines Dante audio-over-IP, integrated DSP, and onboard Wi-Fi into a compact 1/2 rack form factor. It supplies four Class-D amplifier channels delivering 125 watts per channel or 2×250 watts when bridged, supporting both low-impedance and constant-voltage speaker configurations. The unit is designed to centralize signal routing, processing, and power management for distributed audio systems.
Key features include 4×4 Dante I/O for low-latency networked audio, built-in wireless access point for browser-based setup, and a full complement of input and output processing functions. The internal DSP provides parametric EQ, FIR support, crossover, delay, compression, and limiting on inputs and outputs. Front-panel LEDs and a clear web UI make monitoring and configuration straightforward from a PC or mobile device.
Performance specifications meet installation demands with a frequency response spanning 20 Hz to 20 kHz and a signal-to-noise ratio greater than 106 dBA at 8 ohms. Total harmonic distortion is specified at 0.05% THD+N, and the amplifier includes protections for DC faults, overloads, short circuits, thermal events, and undervoltage. Advanced dynamic power sharing distributes available power efficiently between channels to handle mixed loads.
Connectivity covers analog balanced Euroblock mic/line inputs and unbalanced RCA inputs, S/PDIF coaxial digital I/O, dedicated GPIO control, and both Ethernet and four Dante RJ45 ports for AoIP. The FXD125.4 supports selectable Low-Z or Hi-Z output modes in software, allowing 4/8 ohm, 25V, 70V, or 100V configurations. The Wi-Fi hotspot supports secure peer-to-peer access while Ethernet enables DHCP or static IP integration into larger networks.
Typical applications include multi-zone music distribution in retail and hospitality, paging and background audio in corporate and education facilities, and noise masking or distributed audio in healthcare environments. The integrated DSP and Dante capability make the FXD125.4 suitable for projects where long-distance routing and centralized processing are required. Multiple units can be networked for scalable systems and remote management.
Installation is simplified by the 1/2 rack footprint, removable Euroblock connectors, automatic power sharing, and a browser-based UI that requires no additional software. The chassis uses efficient Class-D amplification and a variable-speed fan for reliable thermal management in rack or surface-mounted deployments. For integrators seeking a compact networked amplifier with comprehensive DSP and Dante connectivity, the FXD125.4 provides a complete, easy-to-configure solution.
