Douk Audio Q2 Pro

Warm Tips: 1. The USB (Type-C) input can transmit audio signals and power the Q2Pro. If the power supply current is less than 2A, please prepare a high-quality DC5V/2A adapter to connect its superior USB interface (DC 5V IN) to ensure ideal performance. 2. The microphone interface on the left is earlier than the right one. If the two MIC inputs are connected, only the left one will work. 3. The volume and bass buttons only control analog audio outputs (RCA/3.5mm headphone jack), and are not valid for optical output. 4. The Q2Pro adopts 1PC SGM8262 and 7PCS NE5532 op amps, only one is pluggable and supports to be replaced by double op-amps like 2134/2604/5532/2068/muse02 etc. 5. 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.
