the input on your main mixer.
TYPICAL SET-UP WITH HM2

stereo line level source to STEREO IN by a standard ¼” TRS
connector

3. Speak into your microphone and then raise the MIC GAIN
level slowly until you reach an ideal level
4. Raise your MIX GAIN level while speaking or singing into your
microphone until you find an appropriate balance between
the two
5. If more outputs are needed, connect MIX THRU to additional
HM2 by a standard ¼” TRS connector.
