User Manual of Douk Audio Q2PRO

Warm Tips

• The USB input (type-C) can transmit audio signals and provide power to the Q2Pro. If the supply current is less than 2A, please prepare a high-quality DC5V/2A adapter to connect its upper USB interface (DC 5V IN) to ensure its ideal performance.
• The microphone interface on the left is prior to the right one. If both MIC inputs are connected, only the left one will work.
• The volume and bass knob only control the analog audio outputs (RCA/3.5mm headphone jack), invalid for the optical output.
• The Q2Pro adopts 1PC SGM8262 and 7PCS NE5532 op amps, only one is pluggable and supports to replaced by dual op-amps like 2134/2604/5532/2068/muse02 etc.
• The Q2Pro supports OTG function and the supplied USB cable supports OTG for Android devices. However, iOS systems require a Lightning to USB camera kit, which you need to prepare yourself.
