Ide Soun
• Over the ear design for hands-free use
• Dual-element, noise cancelling mic capsule
• Improved gain before feedback with high output
sound systems
• Comfortable, slim-line design for long-term use
• Rugged mic boom and suspension
The HM162 headset microphone is a lightweight, noisecancelling design for use with high output PA systems.
The comfortable, over-the-ear headband and flexible
boom place the pickup capsule in an optimum location
just to the left of the user’s mouth. The headband keeps
the pickup in this position as the user moves about, leaving the hands free for other tasks.
The HM162 is furnished with a locking micro connector
for use with Lectrosonics VHF belt pack wireless transmitters.
Rugged materials are used throughout the assembly to
withstand the rigors of heavy use.
A bi-directional, dual-element, noise cancelling microphone capsule rejects extraneous sound and emphasizes the user’s voice for maximum gain before feedback
even in close proximity to sound system loudspeakers.
The lightweight headband includes an adjustable, elastic
neckband to provide a comfortable fit around the back of
the head. The over the ear design also allows the user
to comfortably wear a cap or hat without interfering with
the operation of the microphone.

OPERATING INSTRUCTIONS
1) Place the microphone headband on the head with the headband over the ears. The pickup boom should be
positioned to the left of the mouth with the flexible neckband around the back of the neck.
Rotate the pickup element so that the large opening faces the mouth. Remove the foam windscreen to
observe the large and small openings in the pickup
element, then replace the windscreen.
2) Adjust the flexible neckband so that the frame of the
headset fits comfortably over the ears.
3) Adjust pickup boom so that pickup element is to the
left of the mouth, 1/2” to 1” away from the skin. The
pickup element should not be positioned in front of
the mouth, since breath pops directly into the capsule will cause severe distortion.
4) Route the microphone cable loosely around the body
so that the plug reaches the transmitter without coiling
the microphone cable. Do not coil the cable around the
transmitter.
5) Make sure the pickup element is directed toward the mouth (see photo).
Remove foam windscreen to observe large and small
openings in the pickup. The larger opening must
point toward the mouth for best performance. Do not
position the pickup element directly in front of the
mouth, since breath pops directly into the capsule will
cause severe distortion.
