Dethonray DTR1 Prelude AK4490EQ TI OPA1611 Linux OS HiFi Audiophile Lossless Music Player

Description

Replaying at highest quality with SE output
DTR1 ”Prelude” has adopted minimal navigations hassle-free operation. Built with one single purpose – replaying music in highest quality possible, the minimalist system structure adopts a series of advanced circuitry implementations.

Focusing on the core elements for good sound – Separate power for Decoding and Amplifying

Power plays a huge role in HIFI and portable audio systems. Most portable designs suffer from universal power designs that highly compromises signal processing quality. DTR1 adapts dual high-density battery customized power system, designed for High-Fidelity while ensuring separation of digital and analog power to eliminate circuit noise from the source, alike an enhanced DAP + Amplifier system but with a minimal path and hard soldered joints with no compromises.

The ±8.5V PSU remarkably improves efficiency of clean power supplied to the system, with noticeable qualities in transparency and background noise control without the need to excessively damping the output.

With the precision machining on aviation grade, light-weight aluminum alloy, DTR1 is shielded from EMI disturbance for a cleaner background during replay. Precise structural designs with high reliability parts also a patented user interface are combined in pursuit of perfection in sound and optimization of both hardware and software within the design.

Deeply-customized Linux OS

A super highway for signals” – The DTR1 runs on a deeply-customized Linux OS 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-light weight GUI system ”Ocelot”, Customized GAI (Graphics Abstract Layer), GDI (Graphic Device Interface), IAL (Input Abstract Layer), SCM (System Control Module), Audio files indexing system – promises minimal MMI, high speed navigation and supporting up to indexing 160000 songs!

DAC,use mature VERITA series decoding

DTR1 selects AKM VELVET SOUND VERITA AK4490EQ for its reliability and specific sound performance, the chipset supports up to 32Bit/768K and 4 kinds of switchable digital filters offering different auditory experience. AKM, since its first delta-sigma D/A converter (DAC) in 1989, strives for reproduction of the original sound. Such becomes the philosophy “Real live Sound” aiming at providing an active space in the reproduction of sound just like a live performance.

LPF & AMP
In pursuit of “Real Live Sound”, an important part along the signal path – LPF (Low pass filter) adopts two TI OPA1611 on each channel (L/R). Together with the AK4490 chipset the design illustrates a very lively, dynamic output. The amplification circuitry features a mature AD8397 implementation with low distortion, super loading capability not to mention slew rate of 53v/us and 69M bandwidth, further boosted with ±7V power supply. The ideal power supply breaks limitations in shaping sound, achieving powerful, clean sound with effortless extension.
