Profile
The MM Series condenser microphones feature excellent sound quality as they have wide dynamic range,
rich, bright and detailed sound quality, rapid transient response and is close to natural sound without “box
tone” effect. There are three models:
The MM-90 is fitted with a MU-90 premium interchangeable supercardioid condenser capsule module. Ideal
for the singers to use in the concerts and large venues.
The MM-80 is fitted with a MU-80 premium interchangeable supercardioid condenser capsule module. Ideal
for the stages or KTV.
The MM-707B is fitted with a MU-70 premium interchangeable cardioid condenser capsule module. Ideal for
everyone to use in the karaoke or public address applications.
The capsule modules can be detached and replaced easily, featuring excellent sound quality, low handling/
impact noise and robust.

Design Principle
Based on the principle of an electromagnetic generator, a voice coil is
attached to a thin plastic diaphragm in
the magnetic field of the magnet. When
the diaphragm picks up sound, the voice
coil indirectly converts the sound into an
electrical signal.
Based on the charging/discharging principle
of a capacitor, it employs an extremely thin
metal or metal-coated plastic diaphragm.
Sound pressure changes a static electric
voltage between two poles and converts it
directly into an electrical signal.
Diaphragm
A dynamic microphone’s diaphragm has
to bear the weight of the voice coil, which
is a hundred times more than itself, so
the diaphragm cannot be too thin. The
total weight of its vibration system is
1000 times more than a condenser’s.
The diaphragm is 1/10 the thickness and
1/1000 the weight of a dynamic capsule’s.
Utilizing this extremely thin and light
diaphragm to pick up sound pressure directly
ensures excellent performance in frequency
response, transient response, sensitivity, and
touch noise.

that converts sound pressure on the No voice coil is required.

Signal Output
The output is either directly from the voice The output signal is coupled by vacuum
coil or through a coupling transformer.
tube or FET.
Frequency
Response
Due to the thickness of the diaphragm
and heavy weight of the voice coil, the
high-frequency response cannot be
expanded; moreover, the low-frequency
response drops rapidly because the
impedance of the voice coil grows
weaker as the frequency decreases.
Sensitivity

Phantom power is required.
Transient
Response
Transient response is slow due to the
much heavier diaphragm and voice coil.
Thus, the response to the sound is just
like a fully loaded truck that responds
slowly when accelerating and braking.
Because the diaphragm is very thin and
light, the transient response is fast. The
sound pickup is just like a sport car that can
accelerate and brake very quickly.

Because the diaphragm is extremely thin
and light, it can directly convert sound into
signal output. Hence, its frequency response
can be expanded from ultra-low frequencies
to ultrasonic in a flat and wide response.
