Congratulations on purchasing the M3
microphone.
The M3 was created to allow you to achieve the very
best results from both live performance and in the
studio.
One of the key features of the M3 is that it has been
designed with a switchable PAD and high pass filter,
which gives you greater control of the sound source.
It is battery operated to allow versatility with
locations as well as being manufactured in a sleek
contemporary black design.
Please take time to read through the manual provided
to help you get the very best from your M3.

Powering the M3
The M3 is suitable for a wide range of
applications. Recording, stage, and location work
are all well within the capabilities of this microphone.
Its low noise and full frequency response ensure the
sound quality is at a standard that is expected by
today’s musicians and engineers.
You may use either phantom power (see Specifications
- page 3) or 9V battery to operate your M3.
Phantom power (P48 & P24)
Most professional mixing consoles include a 48 volt
phantom power supply; if yours does not, a separate
one may be used. Whichever power supply or cables
you use, ensure they are professional units and are
working correctly.
Note: When using phantom power, a battery may be
in or out; if a battery is installed it will not be utilised.

To connect an XLR cable;
1. Before you connect your mic, ensure that the XLR
cable you are using is wired correctly to match the
output pins on the M3. The M3 offers a balanced
microphone level output and is wired as follows:
Pin 1 (earth), Pin 2 (+) and Pin 3 (-).
Figure 1 - XLR jack
You may of course use XLR-XLR, XLR-jack, or XLR-
mini jack plugs depending on your relevant input
socket.
2. Make sure you use a high-quality, low-loss XLR
cable that is as short as practical to avoid losses
and distortion.
3. To connect the XLR cable, hold the M3 in one hand
and your 3-pin XLR cable in the other. Align the
slot on the XLR cable to the groove on the inside
of M3 body and insert (figure 2). Ensure that the
XLR cable ‘clicks’ into place so that it can not be
removed unless the release latch is used.

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 fitted 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 fit the battery:
1. Unscrew the lower section of the body to reveal the
battery cavity (figure 3).
Figure 3 - Unscrewing M3 body
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 first. Take note of the plus and minus
symbol on the floor of the battery cavity to ensure
the battery is positioned the correct way (figure 4).

4. Push the battery into place so that it is parallel with
the top of the cavity. Secure the battery in place by
flipping the battery clip over so that it sits on the
battery.
5. Reassemble the body, screwing lower section
firmly together with the upper section.

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 field/
location operation using the 9V battery supply.
The M3 microphone has both a PAD switch and a
Filter switch.
On/Off Filter switch
The filter switch is a multifunctional three position
switch. It will control main power (from battery),
microphone mute and filter selection (figure 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 flat
response to 80Hz cut.
Use the high pass filter
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.

L.E.D. SINGLE FLASH – When the L.E.D. flashes
(illuminates for around one second), the battery power
is ‘good’. This indicates that the microphone has just
been powered.
L.E.D. STAYS ON – When the L.E.D. light illuminates
continuously the battery power is getting low. Please
replace the battery as soon as possible, as the
microphone’s sensitivity is greatly compromised when
operated with a low battery.
Note: When using M3 on battery power, it is a good
idea to keep the microphone in the off position when
not in use. This will save battery power and increase
the battery life. We recommend that during long
periods of non-use the battery should be removed, as
it may leak and potentially damage the microphone.
PAD switch
The PAD setting provides a -10 or -20 dB reduction in
sensitivity and is commonly referred to as attenuation.
To access the PAD switch unscrew the lower section of
the body to reveal the switch (figure 6)
Figure 6 - PAD switch
A small screwdriver or pen can be used to alter the
switch positions as required.
A choice between 0dB, -10dB and -20dB settings can
be selected (figure 7). We recommend you start with
