Operating the M3
The M3 may be connected to a mixer (recording or
live), and battery power will only be required if the
mixer does not have an in-built phantom P48 or P24
supply. Connection may also be made direct to a
portable DAT or other tape machine enabling fi eld/
location operation using the 9V battery supply.
The M3 microphone has both a PAD switch and a
Filter switch.
On/Off Filter switch
The fi lter switch is a multifunctional three position
switch. It will control main power (from battery),
microphone mute and fi lter selection (fi gure 5). Take
the time to learn what each position does so that you
can get the best performance from your M3.
The two-position variable
High-Pass Filter enables
you to step from a fl at
response to 80Hz cut.
Use the high pass fi lter
when you wish to remove
low frequency noise
that is not part of your
intended sound source. Remember however the
tonal characteristics will be affected by this, so it
is important that you listen to the sound both with
and without the HPF in circuit before deciding if it is
appropriate for the source.
L.E.D light indicator
The M3 has a handy power indicator light to help
notify you when the battery is running low.
