Warm tips:
1. This is a tube preamp which needs to be connected with an amplifier or active speakers, cannot drive passive speaker directly. And it is not a phono preamp, cannot work with turntables.
2. The headphone jack output is prior, stereo RCA output will auto disconnected when connecting headphones to its 3.5mm output.
