ART m-three 製品データシート

The ART M-Three multi-pattern wide diaphragm condenser microphone is one of
the most versatile microphones available for your studio toolkit.  Three selectable
polar patterns, two position low frequency roll-off and two position pad switch on
the body of the microphone ensure the M-Three can easily be applied to 
virtually any recording or live application. 

The M-Three is the microphone of choice for recording critical tracks including solo
vocals, saxophones, flutes, brass or woodwinds, acoustic guitars or acoustic bass.
The M-Three excels anywhere superior sound quality is required, yet subtlety and
clarity is paramount.

Due to its rugged construction and ability to handle high SPL, the M-Three is an
outstanding choice for live sound reinforcement or live recording applications. It
can handle the levels youÕd see on an overhead microphone for drum kits or in
front of guitar or bass cabinets.

Controls on the microphone itself include a  -6 & -12dB pad switch, allowing 
distortion-free reproduction of extremely loud at-source signals, and a two position
-12dB/octave low frequency roll off at 100Hz & 200Hz that reduces unnecessary
low end 'boominess' and low frequency interference. 

A Cardioid polar pattern is the standard setting for almost all applications.  It will
give you the best results on most voice and a wide range of instruments.  It offers
full frequency response off of the front of the microphone.  The advantage of 
proximity effect (increased low frequency response when microphone is placed
close to sound source*) and excellent noise rejection from the sides and back, or
180û position of the microphone.

The cardioid pattern is ideal for single instrument or vocal use. The pattern picks up
only sound directly in front of the microphone. Sound from the other direction is
rejected.  In live sound applications and remote recording the M-Three's cardioid
pattern offers excellent feedback rejection and better isolation and will give you the
best results on most vocal applications and a wide range of solo instruments 
including background brass and woodwinds, acoustic stringed instruments (violin,
viola and cello), drums and percussion.

Note: The cardioid symbol on the microphone housing denotes the 'live side', or

front face of the microphone that in all cases should face the performer. 

The Omnidirectional polar pattern picks up sound equally from all around the 
microphone.  This is mostly used for recording ambient sounds, or when recording
in an exceptionally good sounding live room where the character, ambiance and
tone of the studio needs to be recorded, as well as the source voice or instrument.
It would also be the ideal choice for picking up audience interaction in a live 
recording situation.

The Bi-directional or Figure-8 polar pattern will hear sound from both front and back.
This is ideal for recording a solo vocal or instrument with limited proximity effect, 
better off-axis rejection (limited interference from the sides of the 
microphone) while still picking up room ambience or natural reverberation from

behind the microphone.  It can be used for duet vocals or when recording harmony
vocals with two vocalists simultaneously.

As a condenser microphone, the M-Three requires phantom power to 
operate.  A subtle recessed LED under the gold capsule behind the microphone
windscreen will illuminate when phantom power is present, and the microphone
is operational. 

The included heavy-duty shock-mount suspension virtually eliminates vibration
and handling noise, while at the same time safely securing the microphone in any
position needed during the recording process.   

*Vocalists can use the proximity effect to their advantage, adding fullness and more

'bottom end' to the voice. Experienced vocalists can easily   incorporate it as part of

their overall microphone technique. Again, experimentation with microphone 

placement during the recording process is the key.  The omnidirectional polar 

pattern does not exhibit this effect.
