Description
User Replaceable Audio Motherboard
Change to a New Audio System “Just Like That
Built-in dedicated microcontrollers interact with the 665 MCU to enable comprehensive audio adjustments and independently track the operation status of the Audio Motherboards.
Fully modularised the audio system in the DAP, a complete replacement of both the DAC and analogue circuits.
A Journey of Sound Exploration
Each Audio Mainboard Is a Key to Another El Dorado
The Gen2 Audio Mainboards feature a completely reimagined tool-free, quick-release self-locking latch.
Changing the Audio Motherboard will be as simple as:
Press > Pull > and Push > Click
Every Audio Motherboard is a fully optimised solution from the ground up, with every swap becoming an entirely new auditory experience — you will unlock limitless possibilities.
Quad-Channel
Precision Analogue Volume Control
