Features
  • Q5 is a multi-function DAC & headphone amp, with PC-USB / optical / coaxial inputs, compatible with many audio device such as phone, computer, TV, CD player, TV setbox and so on; and with stereo L/R RCA / 6.35 mm & 3.5mm headphone jack outputs, can enjoy HiFi music in different ways.
  • USB input, plug and play, no special software is needed, also support mobile phones with OTG function, very easy to use. And the fiber base is upgraded, optimize the circuit board design, redefine quality and sound.
  • Reasonable circuit layout and concise wiring, the sound is clear and natural, and adopting high-quality chip architecture to achieve much better sound quality:
Adopting ESS9018K2M decoding chip, with higher resolution to reproduce real live music.
CM6642 USB chip to get higher decoding ability, supporting 24Bit / 44.1-192KHz transmission.
OPA2134+NE5532 op amp, with low distortion, low noise, high precision and large dynamic range.
TPA6120A2 headphone amp chip and with protection circuit, with low distortion and strong drive power enough to drive 16-300 ohm headphones.
  • Proper size with exquisite appearance, input switch and USB/OPT/COAX input indicators are designed to show working status clearly. Aluminum case looks cool and fashionable, very suitable for home/office desktop audio system use.


Warm tips:
 
1. Without preamp function, and the line output ( stereo L/R RCA) cannot connect passive speakers directly, needs to work with amplifiers or active speakers.
 
2. Headphone output is prior, if you want line output please make sure the headphone has been pulled out. And 6.35mm and 3.5mm headphone jack can output at the same time while the impedance and output power will both be changed.
 
3. PC-USB supports mobile phones, but Android system needs OTG cable and IOS system needs camera kit, please prepare by yourself.
