Microphone Placement

• Aim the microphone toward the desired source, such as the talker.

• Aim it away from any unwanted source, such as a loudspeaker.

• Place the microphone within 15 to 30cm (6 to 12 in.) of the desired sound source.

• Always use the supplied windscreen or optional metal windscreen to control breath noise.

• If four or more microphones will be open at the same time, use of an automatic mixer, such as the Shure

SCM810 or SCM410, is recommended.

Permanent Installation

Mount the microphone using one of the following methods.

Flange

1. Drill a 22 mm (7/8 in.) diameter hole in the desired location.

2. Trace and drill three starter holes for the supplied screws using the flange as a template.

3. Insert the preamplifier through the mounting flange.

4. Slip the mounting flange retaining ring over the bottom of the preamplifier and slide it up until it is flush to the
bottom of the flange. Then press the ring firmly into place.

5. Secure the flange to the mounting surface with three screws.
