CARDIOID MODE: is perfect for recording sounds directly in front of the
microphone. This is the most used polar pattern. It is the most benecial
and best pattern for streaming and gaming.
BIDIRECTIONAL MODE: records sound from the front and rear of the
microphone. It's typically used for interviews but can be used by anyone
sitting on opposite sides of the mic.
STEREO MODE: uses both left and right channels to capture a realistic
general sound image. It's great for recording musical instruments or
acoustics.
OMNIDIRECTIONAL MODE: picks up sound equally from all directions.
This mode is best for multi-person broadcasts so you can capture
sound from around the room.

FREQUENCY RESPONSE DIAGRAMSELECTING SOFTWARE
You have many choices in recording software.
Select the program that will best suit your audio needs and budget.
SETTING YOUR SOFTWARE LEVELS
The correct adjustment of microphone level is Important for optimum performance.
Ideally, the microphone level should be as high as possible without overloading
the input of your computer.
If you hear distortion or if your recording program shows levels that are consist-
ently overloaded (at peak levels), turn the microphone volume or level) down. Do
this using the control panel (or system preferences) settings or through your
recording software.
If your recording program shows insucient level, you can increase the micro-
phone gain either from the control panel (or system preferences) settings or
through your recording program.
POSITIONING YOUR MICROPHONE
It is important to position the microphone directly in line (on axis) with the person
speaking/singing or instrument (or other sound source) to achieve the best
frequency response of the microphone.
This requires the user to speak into the microphone from the Stadium symbol side
positioned towards the mouth. The distance from the mouth should be about 1
inch. or 10 - 40mm for optimal recording.
For use in speaking/singing applications, the ideal placement for the microphone is
directly in front of the person speaking/singing.
The same placement is optimal when you mic an instrument such as an acoustic
guitar, drums or piano. Experiment with dierent mic placements to nd the best
sound for your particular setup based on the Polar pattern selected.
