Warm Tips
1. Without power adapter, and EQ5 needs to be powered by separate USB power supply, don't use the USB port of computers or share the power supply with audio source, otherwise common ground noise will be caused.
2. Stereo RCA and 3.5mm AUX input are in parallel, two inputs and outputs will work simultaneously, so please don't connect RCA and 3.5mm AUX input at the same time avoid signal mixing.
3. EQ5-PRO can input and output audio signal without power supply in bypass mode, but the signal without any preamplification, the VU meters also don't work.
