FDX-15

FDX SERIES 4 CHANNEL DIGITAL POWER AMPLIFIER

Key Features:

  • Delivers 4 channels, each providing up to 1700W @ 8Ω, with a lightweight design of only 9kg.
  • Utilizes ultra-efficient FTD-class switching power technology , offering excellent reliability, noise-free operation, superior transient response, and low power consumption.
  • Features a sleek touchscreen DSP interface, with optional Dante compatibility for professional-grade performance.
  • Equipped with an adjustable VPL output voltage limiter, making the amplifier adaptable to any system.
  • Integrated with a full protection system covering overcurrent, DC, VHF, short-circuit, main fuse failure, and soft-start circuits.
  • Designed to operate reliably even in harsh conditions, using thousands of copper heat sinks for rapid heat dissipation. All heat-generating components are aligned within a unified airflow path for consistent and effective cooling.
  • Built-in professional-grade DSP with 96kHz sampling frequency, supporting IIR, FIR, crossovers, dynamic EQ, gain control, and other precise functions—with storage for up to 50 user presets.
