QA360 Portable HiFi Lossless Music Player

Description:

QLS QA360 Portable HiFi lossless music player is QLS-HiFi’stop line digital music playback equipment that integrated digital music player, DAC and headphone amplifier altogether. QA360 is based on the QA660&QA860 digital music player with dedicated improvementon the digital output circuit, along with the DAC and headphone amplifier module which we spent over 3 years on developing.

It is an all-in-one portable SD card HiFi wav music player, It offers studio-master-tape sound quality and uncompromising file playback capability, It has a high quality DAC and headphone amplifier integrated into its tiny body. The headphone output is able to drive most 8-300Ω headphone in the market.

The Single Threaded Software Framework

QA360 implemented QLS-HiFi’s unique proprietary technology – the single threaded software framework. This technology ensured ultra-low jitters and high accuracy in playback of digital music by occupying the whole CPU with the single music reading and decoding program during the music playback.We keep it simple as always for supporting the simplest SD media cards only, however on the other hand we make every attempt to improve the back end qualities so providing the best value to againstthe priceto the true audiophiles. QA360 is the continuing persistence in pursuit of our belief on HiFi equipment development.

24bit/192KHz wav and DSD Support

QA360 supports Studio Master wav files in 24bit/192KHz and DSD64/1bit/Stereo.  DSD files can be streamed out of the digital output in DoP format, and hardware converted to analog singles directly through the internal DAC as well.
