- Single-ended output for high-quality playback
- DTR1 ”Prelude” adopt simple and humanized interface and button layout, all-button design to convenience all the use of the scene. Minimalist design and system architecture are built for the highest quality music, with advanced circuit design to achieve a high limit to reduce the system load.
- The shell is precision machined and anodized on the surface of aviation-grade aluminum alloy to enhance shielding and eliminate external signal interference.
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.
Deeply-customized Linux OS
- A superhighway for signals” – The DTR1 runs on a deeply-customized Linux OS and audio sub-system which utilizes an OSS sub-system 30% higher in efficiency than the ALSA audio sub-system. The customized and optimized decode engine “Nature” synergize effectively with the Linux OS, decodes in optimal condition and reduces transmission delay.
- Patented ultra-lightweight GUI system ”Ocelot”, Customized GAI (Graphics Abstract Layer), GDI (Graphic Device Interface), IAL (Input Abstract Layer), SCM (System Control Module), Audio files indexing system –uncompromising underlying custom design brings out the minimal MMI, high speed navigation and supporting up to indexing 160000 songs!
Select the mature VERITA series decoder
- Select AKM VELVET SOUND VERITA series AK4490EQ (not AK4490EN), provide 2Bit/768K format support, 4 types of adjustable digital filters, presenting different listening experience. Adhering to the design philosophy of VERITA series "Real Live Sound", Prelude combines the custom power supply design with the back-ended tuning circuit, and takes the final sense of hearing as the guide, combining the quality and the sense of hearing perfectly.
No need to take the portable AMP
- LPF (Low pass filter) adopts two pieces TI OPA1611 on each channel (L/R), make the AK4490EQ "Real Live Sound" feature full show, no longer nitpick about pop and classic music. The amplifier circuit adopts the AD8397 with low distortion and super carrying capacity, supplemented by the OCL circuit design with ±7.5V power supply, optimized the high and low gain circuit design, for IEMS(in-ear monitors system)/HEADSTY optimized volume control curve and the earphones with high and low impedance maintained better impulse and natural balanced listening.
