It is better to have a line input for the recording pen, and then connect the aux or grouped (such as sub and alt3-4) output of the mixer. The fader is used for normal field amplification, and the output level of the microphone channel is adjusted by aux (subject to the display level of the recording pen). If the mixer is grouped and connected to the recorder, press the grouping selection key of the microphone channel. At this time, the tape recorder only records the sound of the Mike channel, and of course, the live music is also easy to be collected by Mike.

In case of advertising, the equipment will be left downstairs.
