Yulong A39 Headphone Amplifier & Preamplifier

Key Features:

  • High-Performance Audio: Equipped with a constant-current Class A 6W balanced headphone amplifier and a reference-grade preamplifier, the A39 offers slightly warm tonality and minimal distortion (0.0002% THD+N, SNR >120dB, crosstalk <-100dB) for pristine, lossless sound.
  • Advanced Volume Control: Utilizes a CPU + FPGA latching relay and R2R resistor network for pure, transparent volume adjustments with up to 99 levels, eliminating sound quality loss and electromagnetic interference.
  • Versatile Connectivity: Features XLR balanced and RCA inputs/outputs for the preamplifier, and 4.4mm, 6.35mm, and XLR outputs for the headphone amplifier with impedance switching for compatibility with a wide range of earbuds and headphones.
  • Robust Power & Protection: Powered by a custom 50W NORATEL toroidal transformer and linear power supply, with CPU-monitored temperature, voltage, overcurrent protection, delayed startup, and quick shutdown for safe operation.
  • Intuitive Interface: Includes an IPS LCD screen displaying dynamic spectrums and retro VU meters, paired with a single-knob or remote control for easy navigation and human-machine interaction.
  • Compact Design: Housed in an A4-sized CNC-machined aluminum chassis for efficient heat dissipation, combining aesthetics with practicality. Perfectly pairs with the Yulong D39 streaming DAC for a complete desktop audio system.
  • Global Compatibility: Features an external global voltage switch and USB DFU interface for firmware updates, ensuring adaptability across regions and future-proofing.

Technology and Innovations:

The Yulong A39 features a high-speed CPU running a streamlined Linux 4.4 operating system, delivering real-time monitoring and control of current, voltage, and temperature for unparalleled performance and reliability. Its advanced FPGA and R2R resistor network ensure lossless volume control, while the constant-current Class A amplification provides rich, warm tonality with minimal distortion.
