General Description
Dual microphone conguration features
The M-1 features two built-in microphone elements, one dynamic and one condenser.
The unique output signals may be individually crafted and then blended to produce a
single rich voice signal. The condenser microphone responds to a broad frequency
range including the distinctive crisp highs, while the dynamic microphone adds depth
and warmth, providing the emotional subtext desirable for a genial “ragchew”. The M-1
lets you ne-tune and balance the two microphone sources to create a sound that will
compliment your own voice.
Nine-band graphic equalizer for each microphone element
The nine-band graphic equalizer is applied to each microphone element independently,
giving total exibility to accentuate and enhance the frequency characteristics of both
the dynamic and condenser microphone output signals. The individual frequency proles
are easily adjusted on the graphic equalizer, using the rotary encoders below the display. The built-in equalizer memories can store two different groups of settings for each
microphone. Stored settings (Memories 1 and 2) can be accessed instantly.
A through (at) preset is also provided. By blending the two microphone outputs together, you can create your own unique tonal quality. The M-1 adds a new level to the audio
creative process.
Treble boost cowling produces a unique tonal texture
The simple clip-on cowling enhances the high-frequency response of both microphone
elements, and can minimize the aural interference from either side. The cowling serves
to concentrate the voice input with a peak at around 1 - 1.5 kHz, producing a unique tonal texture.
Air cylinder magnetic contactless PTT key
The PTT key with contactless triple air cylinder magnetic construction delivers smooth
ngertip-sensitive operation over an extended stroke distance.
The key has been designed with optimal balance between key weight and stroke to provide the perfect tactile response. Meanwhile, the contactless switch provides years of
fault-free operation with minimal mechanical degradation.
The built-in record and playback feature provides monitoring your voice in the head-
r
phones to allow meticulous evaluation and adjustment.
Features a built-in, one-click DSP lter that is independent of the graphic equalizer.
r
Connect headphones directly to the M-1 and check the microphone audio in real
r
time, listen to test recordings, or monitor the transceiver signal.
The M-1 microphone outputs include a balanced XLR jack as used on professional
r
sound equipment for superior audio quality and noise shielding.

Safety Precautions
Please do not use a voltage other than
the specied power supply voltage.
Doing so could cause re, electric shock or
damage to the equipment.
Do not install in places where the unit
risks getting wet (such as near a humidier).
Doing so may result in re, electric shock
or damage.
Do not use a power supply cable other
than the one provided.
Doing so could cause re, electric shock or
damage to the equipment.
Do not place heavy objects on the power
supply cable or connection cable, forcibly bend, twist or pull on the cables, or
heat or modify them.
Doing so may scratch or damage the cables, resulting in re, electric shock or damage to the equipment.
CAUTION
Do not place the unit on an unstable
place or a place subject to much vibration.
The unit may fall or tip over, resulting in
re, injury or malfunction.
Do not place heavy objects on top of the
unit.
The unit may fall or tip over, resulting in
injury.
Do not place objects containing water,
such as vases, cosmetics or cups, on
top of the unit.
The water may spill and get inside the unit,
resulting in re or malfunction.
Do not place small metal objects such
as clips on top of the unit.
The object may get inside, resulting in re
or malfunction.
Do not place the unit in humid or dusty
places.
Doing so could cause re or malfunction.
Do not use the headphones at high volume.
Listening to continuous loud sound over the
headphones may the damage the ears.
When using the headphones, lower the
volume to the minimum before turning
on the power.
Failure to do so may cause hearing disorders.
Do not pull on the cable section when
disconnecting the power supply cable
or connection cable.
Doing so could cause fire, electric shock
or damage to the equipment. Hold the plug
or the connector when disconnecting the
cable.
Do not use the power supply cable or
connection cable if it is damaged or if
the connection of the power connector
is loose.
Doing so could cause fire, electric shock
or damage to the equipment. Contact your
dealer or our customer support.

MIC
The unit includes a built-in dynamic microphone and a condenser microphone that are developed for communications equipment. The condenser
microphone provides crisp sound with transparent frequency characteristics
up to high frequencies. The dynamic microphone produces a thick, deep,
warm sound quality that is suited for informal chatting. These two types
of microphones are each equipped with an independent 9-band graphic
equalizers, allowing the output frequency characteristics of the separate
elements to be precisely controlled. It is also possible to combine the audio
output signals from the two microphone elements.
The included treble boost cowling may be
r
installed to block sounds from the sides of
the microphone, resulting in unique frequency characteristics as if the sound were condensed with a peak response in the vicinity
of 1 to 1.5 kHz. To install the cowling, press it
straight on from the front to cover the microphone. To remove, slide it straight off.
Angle adjustment knobs
The angle of the microphone may be adjusted by loosening (turn counterclockwise) the
knobs on the left and right side of the pivot
top. Place the microphone in the desired position and then tighten the knobs (turn them
clockwise) to secure the microphone.

Height adjustment ring
The height of the microphone can be precisely adjusted. Turn the compression ring
