Parameters Chip architecture: CSR8675 (Bluetooth chip) + XMOS HU400 (USB chip) +ESS9038 (DAC chip) Audio input: Bluetooth / PC-USB / Coaxial / Optical Audio output: Stereo RCA / XLR / 6.35mm & 4.4mm headphone jack Bluetooth version: 5.0 (support APTX /APTX-HD / LDAC) Sampling rate supported:PC-USB: PCM 768KHz / 32bit DSD512Coaxial / Optical: 192KHz / 24bitPC-USB operation system supported: W7/W8/W10/MAC/Linux Frequency response: 10Hz-40KHz (±0.2dB) THD: <0.0003% S/N ratio: ≥118dB Output level: 2.4V (RCA) / 4.8V (XLR) Matched headphone impedance: 16-600Ω Headphone output power: 2W (4.4mm) / 520mW (6.35mm) Working voltage: DC 12V Dimensions(W*D*H): 167*128*42mm / 6.57*4.96*1.65in Package dimensions(W*D*H): 310*240*70mm / 12.20*9.45*2.76in Net weight: 620g / 1.37lb Package weight: 1.1kg / 2.43lb Warm tips: 1. For safer and faster delivery, the remote control may not include batteries (2*AAA), please prepare it by yourself.2. Two headphone outputs or two line outputs can work at the same time, while 6.35mm / 4.4mm headphone jack output are prior, that means stereo RCA and XLR output will auto disconnect when headphones are inserted.3. PC-USB (systems below win10) input need special driver to get 32Bit/768KHz transmission, please contact us for it when you receive H6. It also supports OTG functions, but Android system needs OTG cable and IOS system needs camera kit, please prepare by yourself.
