SE Electronics Microphone Manual

 

Thank you for purchasing this SE Electronics microphone, which was hand built in one of the most 
advanced microphone manufacturing facilities in China. Designed by a team of extremely experienced 
engineers and verified by extensive listening tests.  Each model utilises gold sputtered, ultra-light mylar 
diaphragms in an advanced capsule design.  Your microphone was constructed using the finest quality 
Japanese electronic components and extensively tested to provide you with years of trouble-free 
operation.

*  Note: The USB2200a will lock to 88.2 and 96 K clocks on most software, writing files as 16 bit and, with 
the automatic conversion (bit stuffing), 24 bit files.  Therefore users who have sessions at different rates 
and want to use the mic, in most cases, can.

Pickup Patterns

There are two basic microphone directional patterns, omnidirectional, which picks up sound 
equally from all directions and figure-of-eight, which picks up from both the front and rear of 
the microphone but not from the sides. Combining these two basic patterns creates a cardioid 
or directional response, which simply means the microphone is most sensitive in one particular 
direction. By varying the way in which the omnidirectional and figure-of-eight patterns are 
combined, varying widths of cardioid pattern can be created.   

Cardioid

The USB2200a microphone utilises a Cardioid polar pattern.  Cardioid pattern microphones are 
popular for general-purpose recording as they can be directed at the wanted sound source while 
offering a measure of rejection to sounds approaching the microphone from the rear, and to a 
lesser extent, the sides.  This is the polar pattern of the USB2200a.
Where several musicians are playing together, this reduces the amount of crosstalk between the 
microphones. Cardioid pattern microphones also pick up less of the ‘room sound’, which results 
in a clearer, less ‘coloured’ recording. Note that cardioid microphones belong to the category of 
‘pressure gradient’ microphone as their output signal depends on the differences in air pressure 
between the front and rear of the capsule. 

 

All pressure gradient microphones exhibit some degree of proximity effect, which simply means    

 

that there is a significant rise in their bass response if they are used very close to the sound  

 

 

source.  If desired this can be countered by using the low-cut switch on the microphone or  

 

 

microphone preamplifier.
