QA860 HiFi Digital Lossless Music Player
« on: Oct 30, 2013, 14:48:09 »
Halo :D


QLS ngeluarin barang baru lagi nih. Setelah dulu ada 550, 350, 660, sekarang ada 860 :D



QLS QA860 HiFi digital lossless music player is QLS-HiFi’stop line digital music playback equipment that integrated digital music player, DAC and headphone amplifier altogether. QA860 is based on the hot QA660 digital music player with dedicated improvementon the digital output circuit, along with the DAC and headphone amplifier module which we spent over 2 years on developing and continuing optimizationthrough testing more than 10 major hardware version.

Niat amat, Mas...

The single threaded software framework, the extreme-low jitter clock process circuit, the digital/analog completely separated power supply loops and full isolated mounting rooms for each module are the keys for QA860 to enter into the Hi-End world with far beyond a lot of Hi-end level desktop CD players.

Iya dah...

QA860 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 converted to analog singles directly through the internal DAC as well.

DSD kayaknya makin populer ya, atau nggak?

Highlights:

    Dual 0.5PPM TCXO for 22.5792Mhz and 24.576Mhz.
    High standard power supply design:
    - 2 customized toroidal transformer for digital and analog circuits separately with vibration isolation and absorbing design, and without interfering the digital clock circuit completely.
    - TI top line RF LDO for supplying the DAC chips and clock circuits, which has been proved more suitable for the digital circuit than the top line LDO of Linear Technology in our long time test.
    - Mono concept in designing power supply circuit for each independent function unit.
    - Schurter filter power entry module and fuses.
    Pre-amplifier inside with on/off and volume control through the remote controller (AD1955 is fixed level output to process DSD, as the result the inside pre-amplifier is not functionable).
    High power headphone amplifier integrated for Hi/Low impedance headphones.
    Case vibration isolation design and manufacture.
    4-layers PCB for all circuit boards.

Speification:

    DAC: AD1955 I/V: OPA2134*2    LP and pre-amp: LME49720*3
    Headphone: LME49720+OP2134+TPA6120
    Support:
    - 16bit/24bit, 44.1-192Khz, DSD 1bit 64FS.
    - Audio format supported:
      - WAV :  16/24bit, 44.1~192 kHz.
      - AIFF  :  16/24bit, 44.1~192 kHz.
      - FLAC :  16/24bit, 44.1 kHz~48 kHz, compression level 0~8.
      - APE   :  16 bit, 44.1 kHz, compression level fast and normal.
      - ALAC :  16 bit, 44.1 kHz
      - MP3   :  16bit, 44.1/48 kHz, 96k bps~320k bps, CBR/VBR/ABR encoding.
      - CUE   :  ANSI / UNICODE / UTF-8 Encoding.
      - DSD   :  DSD64 1bit, Stereo---DIFF、DSF、SACD ISO.
    - Digital output: PCM / Dolby Digital output/ DTS Digital output / DSD (DoP V1.0).
    Digital output: Coaxial*1, Optical*1.
    Digital input: Coaxial*1, Optical*1 (up to 24bit/192Khz).
    Analog output: RCA*1, XLR balance*1.
    Headphone: 6.35mm*2
    Analog output:
    - 0dBFS signal output level: 2.5V RMS
    - Frequency response: 0-50Khz
    - S/N: 120dB
    - Dynamic Range: 118dB
    - Total Harmonic distortion: 0.0007%
    - Headphone power output: 600Ω@120mw, 300Ω@250mw,150Ω@5500mw,64Ω@1.2W,32Ω@2W
    Power: <30W
    Input Voltage: AC 110V and AC 220V selectable
    Dimensions: 215mm x 330mm x 100 mm
    Weight: 5KG
