Battery power (9 volt)
If phantom power is not available on your equipment,
you will need to use battery power. To use battery
power, a 9 Volt (PP3) battery should be fi tted into the
cavity within the microphone body ensuring correct
polarity (+ to + and - to -).
We recommend that you use a high quality alkaline
battery. Tests have shown a life expectancy for a high
quality alkaline battery used in the M3 to be in excess
of 300 hours. This is roughly the equivalent of 6 hours
usage per week for a year.
To fi t the battery:
1. Unscrew the lower section of the body to reveal the
battery cavity (fi gure 3).

2. Flip open the battery clip so that it doesn’t
interfere with loading the battery.
3. Insert the battery into the cavity, inserting the non
-terminal side fi rst. Take note of the plus and minus
symbol on the fl oor of the battery cavity to ensure
the battery is positioned the correct way (fi gure 4).
