microphone with a stereo source making it an ideal unit for
personal monitoring, either on stage or in the studio.

• Balanced XLR microphone THRU to link signal to the main
mixer
• ¼” stereo INPUT for feeding a stereo monitor signal from
the main mixer
• ¼” stereo MIX THRU for sending the same stereo signal to
multiple units
• MONO switch for summing line level input
• MIC GAIN to set the microphone at a desired level
• MIX GAIN to control the level of stereo input signal
• Headphone outputs on ¼” & 3.5mm jack connectors
• 20V AC adapter included

SETTING UP YOUR HM2
To set up your HM2, make sure all the knobs are turned all the
way down. Connect the supplied DC adapter to the 20V DC
POWER INPUT on the rear panel and then plug the adapter into
any standard AC outlet.
Connect your microphone to the HM2 MIC INPUT using a
standard balanced XLR microphone cable. Then use a second
standard microphone cable to connect the MIC THRU output to
the input on your main mixer.
TYPICAL SET-UP WITH HM2
1. Connect the headphone output from your main mixer, or any
stereo line level source to STEREO IN by a standard ¼” TRS
connector
2. Connect your headphones to OUTPUT
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.

Note: Make sure the GAIN knob is turned all the way down be-

raise the signal to a comfortable listening volume.
