pro master SGM1 User manual

Thank you for purchasing the ProMaster SGM1 Compact Shotgun Microphone. For the
best performance, please read this manual thoroughly before using the product.
The SGM1 is a directional microphone. By mounting it to the top of your camera or
camcorder it is pointed in the same direction as your lens. This ensures the audio will be
focused on your subject while distracting background noise is reduced. Your videos will
benefit from clearer, more understandable sound.
Precautions.
!Avoid water, rain, and moisture as it can damage the SGM1
!Avoid extreme temperatures, especially above 60°C / 140°F.
!The SGM1 microphone is a sensitive, precision instrument. Avoid dropping or
shaking it.
!Use only a high quality 1.5V alkaline AA battery. Lower voltage rechargeable
batteries may not provide proper operation.
!Remove the battery from the microphone when it is not in use for an extended period
of time.
!Do not disassemble or attempt to repair this product yourself. Doing so will void the
warranty.
!Keep the product and parts away from small children to avoid hazard from choking or
swallowing.

Battery Installation
1. Unscrew the base of the microphone then pull it away from the SGM1 body.
2. Insert the battery according the “+” “-” sign in the compartment. Please be careful to
install the battery in the proper orientation and use a high quality 1.5V AA. Do not use
lower a lower voltage rechargeable battery.
3. Return the base of the microphone to its original position and screw it back in place.

Connecting The Microphone To Your Camera
1. With your camera powered OFF slide the foot of the shoe mount microphone holder
all the way into your camera’s shoe mount. Next rotate the wheel clockwise to tighten
it. Now mount one foam windscreen onto the microphone head.
2. With the SGM1 powered OFF mount it to the shoe mount microphone holder. It will
‘clip’ into place with light pressure. You can adjust the angle of the microphone head
by loosening the thumb screw on the side of the shoe mount holder, tilting the
assembly, and then re-tightening the thumb screw.
3. Now use the coiled cable to connect the SGM1 to your camera’s audio input jack.

Operation
Power ON both your camera and the SGM1 microphone. Use the SGM1’s ON / OFF
switch and watch the red LED light illuminate to confirm you have battery power. Operate
your camera in video mode as you normally would. Most cameras will automatically switch
from their internal mic system to an external microphone by recognizing it is connected to
the input jack. You may find the audio performance of your camera improves even more
by adjusting or turning OFF your camera’s AGC or Automatic Gain Control. Refer to your
camera’s instruction manual for more information.
Note: It is important to watch the red LED power light on the SGM1 is illuminated during
your videography. If the light goes out be sure to replace the battery before continuing to
take video. A loss of power in the SGM1 may result in no audio being recorded
whatsoever.
