Desktop Bluetooth Receiver and Amplifier

Switch to Bluetooth mode with the touch of a button, receiving audio through hi-res Bluetooth codecs such as UAT, LDAC, AAC, and SBC. Decode and output to desktop speakers and other wired audio devices, bringing a wireless world to them.

Massive Driving Power

Exceeding the power of many desktop headphone amplifiers, the 1523mW output easily drives all types of full-size headphones.

Cyberpunk Industrial Design

With instantly recognizable body lines, front-facing color LEDs, and a transparent OLED display, the FD5 captivates visitors with its cyberpunk retro-futurism aesthetic.

Discrete Power Supply

An isolated power supply shields the analog conversion/amplification circuitry from EMI from the power supply. The fully isolated power supply includes filtering and regeneration to isolate the FD5 from any electrical grid noise. It uses 10 ELNA SILMIC II capacitors in the power supply section and an isolated DC power supply with an analog module powered by a high-resolution OPA1652 opamp for active noise isolation and voltage regulation.

4x AK4493 DAC Array

Utilizing four AKM AK4493 DAC chips, the FD5 uses current mode amplification for powerful output and an exceptional signal-to-noise ratio. The system includes class A/AB amplification switch, LPF comprising 6 OPA1612, high-quality headphone amplification with 2 ADA4625-2, and a fully discrete headphone amplifier formed of 32 hand-matched transistors.

Dual Femtosecond-Grade Crystal Oscillators

The FPGA-based clock regeneration system is equipped with 45.158MHz and 49.152MHz femtosecond-grade audio-only crystal oscillators. Responsible for 44.1kHz-based and 48kHz-based audio, the system eliminates jitter, providing a precise clock source for high-quality audio.

Full Set of Ports

Standard ports include separate 3.5mm SE and 4.4mm balanced headphone ports, with an included converter cable to 6.35mm for use with all IEMs, earbuds, and full-sized headphones. Additional 3.5mm SE and 4.4mm balanced line-out ports connect to additional headphone amplifiers.

Hi-Res Audio Support

Supports PCM 32/768 and DSD512, meeting pro audio equipment standards and consumer audio demands. MQA 16x unfolding provides master-tape quality audio, offering a concert or studio-like experience.

Multi-System Support

Plug-and-play support for Mac, Windows, iOS, and Android systems.

Dual Hi-Res Certification

Guaranteed high fidelity with dual Hi-Res and Hi-Res Wireless audio certifications.

All-Metal Chassis

Aluminum alloy chassis with glass status pane and transparent color display for status and operations at a glance. The 100-step volume knob coupled with true analog volume control.
