This is the explanation for the board:
Product introduction:
Microphone - microphone front stage amplification - microphone reverberation board - power amplifier. This microphone reverberation board can be combined with our max9812 electret microphone front stage board to form an OK board with reverberation function.

Note: the board is a separate reverberation board without microphone front stage amplification

Board working voltage: DC 6-15v

How do I change the Microphone Level input for this board to Line Level?

Thank you in advance for any help

The AliExpress explanation of the board is terrible!

I think the board you have produces audio reverberation. They say its input can be another board which is a microphone preamp.
Then the input level to the reverberation board is line level.

AliExpress also seems to say that the reverberation board can drive another board which is a power amplifier.
What is an OK board??
