DTR1 Plus Power Design
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 a dual high-density battery customised 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 ±8.4V 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.
DTR1 Plus AKM Chipset
The DTR1+ uses the AK4490EQ chipset. The chipset supports 32Bit/768K and switchable digital filters offering different auditory experiences. The AK4490EQ is very reliable and has an exceptional sound performance. Since its first delta-sigma D/A converter (DAC) in 1989, AKM strives for original sound. The philosophy of ”Velvet Sound” and the reproduction of sound like a live performance.
The DTR1 runs on a deeply-customised Linux OS audio sub-system. The Audio OSS sub-system is 30% higher in efficiency than ALSA audio sub-systems.
This creates “A superhighway for signals” sounding natural and fluid. The ”Nature” decode engine works in optimal synergize with the custom Linux OS. All resulting in optimal conditions and reducing transmission delays.
The DTR1 plus is super responsive and intuitive with a user interface called ”Ocelot”. This Ultra fast and lightweight user interface is now improved for the DTR1 Plus.
High speed navigation and supporting indexing up to 160000 songs!
Summing up highlights of the Dethonray approach:
- A deeply-customised Linux OS
- Advanced dual clean power circuitry to ensure Separate power for decoding and amplifying.
- Shielded from EMI disturbance by the beautifully precision-machined aviation grade, light-weight aluminium alloy body.
