Frequency Response Polar Pattern

The Azden SGM-250 can operate on either a single AA
battery or standard 48V phantom power. The user may
select the desired power mode via the Power Switch.
To install a battery, first unscrew the bottom metal sleeve
by turning it counter-clockwise while holding the upper
barrel of the microphone still. Pull the bottom sleeve down
to uncover the battery compartment and stop when you
feel resistance (the sleeve will remain attached). Insert a
new AA battery, matching the polarity indicated on the
battery compartment. Once the battery is installed, push
the bottom sleeve back up and screw clockwise to tighten.
Tightening should be smooth and easy. Do not force the
sleeve as you tighten or you may damage the threads.
LED Battery Indicator
When the power switch is turned to “BATT ON”
• LED comes on briefly and turns off: The battery has sufficient power.
• LED comes on blinking: The battery has low power.
• LED does not come on: Either there is no battery installed or the
battery is dead.
Typical total battery life with the SGM-250 is 100 hours. When the
LED blinks, the battery will have about 10 hours of use remaining,
however, audio quality will soon start to diminish. It is recommended
that you change the battery once you see a blinking LED.
The Azden SGM-250 comes with a custom shock mount and foam
windscreen.
Power Switch
BATT ON: Turn the switch to this position when using battery power.
OFF / 48V: Turn the switch to this position when using phantom power
and/or not using the microphone. (If the switch is left in the “BATT ON”
position, it will keep drawing power from the battery.)
