High-Resolution PCM & DSD Decoding
The dual high-performance DAC chipset in the Aune BU2 provides excellent audio signal decoding characteristics to the device. It is capable of decoding high-resolution 32-Bit/768kHz PCM and Native DSD512 signals. It maintains a lower noise-floor, high dynamic range, and a cleaner background in the output signal.
Four Independent Amplifiers To Bring Out the True Potential of Aune BU2
AUNE BU2 adopts the highly trusted Low-ripple positive and negative pump power circuit of the classic B1 headphone amplifier. With Dual ES9318 Sabre DAC chips and four independent amplifiers, the Aune BU2 can satisfy the needs of your favorite IEMs and Headphones with ease.
Dual Low-Jitter Crystal Oscillators For Digital Audio Clock Synchronisation
Aune Audio is a tech giant behind many successful desktop-grade clock systems. They have implemented two low-jitter 45M/49M crystal oscillators which are synchronized with the DAC chips by the USB chip, ensuring a properly synced audio chain in your pocket.
Accurate Volume Adjustment using R2R Volume Technology
Aune BU2 has dynamic volume control technology consisting of electronic switches and an R2R ladder network. At lower volume levels, the R2R controls the subtle volume with a precisely matched resistance array. This helps in accurate volume adjustment for different impedance IEMs/Headphones.
Multi-Function Knob Button
The volume knob also hides a button underneath it. All settings, controls of the Aune BU2 can be adjusted using this volume knob only.
