Linux OS audio sub-system
Supports handle 100,000 songs in 6 minutes which stored in the Micro SD card.
A super highway for signals” – The DTR1 runs on a deeply-customized Linux OS audio sub-system which utilize a 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!
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 powerto 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 ±8.4V PSUremarkably 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.
DTR1 selects AK4490EQ for its reliability and specific sound performance,
the chipset supports up to 32Bit/768K and 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 ”Velvet Sound” aiming at providing an active space in the
reproduction of sound just like a live performance.
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.
