Focusing on the core elements for good sound – separate power for Decoding and Amplifying
- Power supply circuit design plays an important role in portable audio system. Conventional players limited to a single battery and a common power supply system seriously impair the quality of signal processing. DTR1 uses a custom power supply system that separates digital/analog power from the source to eliminate noise interference from the digital circuit and make the sound cleaner. ±8.5v power supply, avoid the noise of booster circuit, improve power supply efficiency. Analog voltage conversion module USES high-precision power supply conversion IC, ultra-low noise and high-power reserve, to ensure that the playback process fully highlights the music dynamic, details and transparency. The dual high-density battery custom power supply architecture system is designed for low distortion playback, The dual high-density battery custom power supply architecture system is designed for low-distortion playback and is a major reason to ensure the separation of digital and analog power supplies to eliminate circuit noise. The independent amplifier part is added under the shortest circuit and minimum volume.
- 8.5VPSU significantly improves the cleanliness of the power supply without adding damping to control the background noise. You can hear more transparent, high-density sound output and natural, high-dynamic sound performance.
Simple but uncompromising aviation grade high precision machined shell
- The lightweight and high-strength aluminum alloy shell can effectively shield EMI interference, reduce background noise and enhance service stability while improving product practicality. Reliable material selection combined with precise structural design and patented user interface to pursue the ultimate sound playback with integrated design.
