To attach the microphone to a boom pole make sure the
SMS-45 is turned off and follow these steps:
1. Match the threaded post on the end of the boom
pole with the threaded socket of the SMS-45’s mic
holder.
2. Screw the boom pole into the threaded socket until
it is secure.
3. Insert the microphone into the mic holder making
sure that the power/high-pass filter switch is
accessible.
To switch the microphone on, set the power switch to
either the L-CUT or FLAT position.

Using the High-Pass Filter
The high-pass filter attenuates noise below 80 Hz. This helps prevent the microphone from recording
low-frequency noises like the rumble of an air conditioner, blower, or fan.
To turn on the high-pass filter, slide the switch on the microphone to the L-CUT position. To turn off the
high-pass filter, slide the switch to the FLAT position.
Recording
1. Plug the 3.5 mm stereo mini connector into the audio input jack of your camera or portable
recorder.
2. Place the foam windscreen over the microphone.
3. Slide the power/high-pass filter.
4. Switch to the FLAT or L-CUT position.
5. You are now ready to record. Consult the instructions of your camera or recording device for
directions on recording.

Recording Tips:
▪ The foam windscreen should always be used to diminish vocal plosives and wind noise.
▪ It is always advisable to do a test recording first and listen to the playback before recording a
complete take.
The Desktop Mic Stand
The SMS-45 can be used as a stand-alone microphone. For tabletop placement of the microphone
follow these steps:
1. Attach the shoe-mount adapter by screwing in the
5/8" threaded post of the adapter into the 5/8"
threaded socket of the mic holder.
2. With the closed end of the mic stand slanted down
toward the table top, slide the microphone just
above the mounting foot onto the stand so that it
rests on the flat section of the legs.
3. Tighten the locking wheel by rotating it clockwise.
