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 8-300
headphone in the market.
The Single
Threaded Software Framework
QA360 implemented QLS-HiFi s unique proprietary technology C
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.
