pro master LM1 User manual

1
Thank you for your purchase of the ProMaster LM1
microphone. It is a terrific device for improving the sound
quality captured while recording video. The LM1 is
designed to work close to the source of sound, which is
often your own voice. The distance from your mouth to shirt
collar is ideal and will allow the LM1 to “hear” you while
reducing other outside noises.
Please read these instructions carefully to understand and
get the best performance from your new microphone.

Mounting the Microphone
Tips for Operation
- When not in use for a short period of time, set the LM1
input switch (4) to its smart device setting to save battery
power
- When not in use for an extended period of time, remove
the CR2032 battery from the LM1 to conserve the battery
and avoid the danger of leaking.
- The main audio cable of the LM1 is 4’ long, which is great
for clipping the main mic capsule to a shirt collar, attaching
the switch body to a belt and running the cable behind
your back or through your shirt. From there, the cable can
be plugged into a recorder or wireless audio transmitter.
Or, you can connect the 16 ½’ extension cable to hard-wire
the LM1 to your recording device which may be further
away.
Setting the Microphone
The LM1 works with a wide variety of devices from cameras and
camcorders to smartphones and tablets. For a camera,
camcorder or any device with a 3.5mm TRS audio input jack, set
the LM1 input switch (4) to the “camera” icon setting. The small,
red LED light (5) will illuminate in this setting. For smartphones,
tablets, computers, and other devices using a 3.5mm TRRS
audio input jack, set the LM1 input switch to the “smart device”
icon setting. The small, red LED light (5) will go dark in this mode.

The alligator clip (2) is normally used for attaching the LM1 to a
shirt color. This clip should already be attached to the LM1
when you first open the box. If it is not, locate the alligator clip
(2) and snap it onto the LM1 just below the microphone tip. You
can also reverse the direction of the alligator clip by pulling it
off the LM1, changing its direction and reattaching it.
Squeeze the alligator clip (2) to open its jaws and attach it to a
shirt or anyplace near the source of sound for the LM1 (most
often your own voice). Use the belt clip (3) to attach the
switch-body portion of the LM1 to a belt or other area of
clothing that is not very conspicuous.
Because the LM1 has an Omnidirectional sound pickup you
can position it in whatever orientation is most convenient.
Installing the Battery
Remove the battery hatch (6). Locate
the included CR2032 battery (11) and
remove its packaging. Insert the
CR2032 with the – side going
face-down and the + side facing up,
towards the battery hatch opening.
Reinstall the battery hatch (6).
Using the Windscreens
Two types of windscreen are included with this kit. The foam
windscreen (7) is great for general-purpose use. It will reduce
unwanted noise from light movement of air. Use the foam
windscreen indoors or outdoors on calm days. The furry
windscreen (8) reduces wind noise when it is more prevalent.
Use it indoors on days when you can feel the wind blowing.
Once chosen, simply slide the preferred windscreen over the
mic capsule (tip) of the LM1.
