Shure SM35 Headworn Microphone

Product Overview

The Shure SM35 is a headworn electret condenser microphone, designed for use with a wireless bodypack transmitter in live stage performances.

Visual Description: Microphone and Placement

The product features a headworn microphone design. Diagram 1 shows the microphone boom with a windscreen attached. Diagram 2 illustrates the headband being placed around the back of the head. Diagram 3 depicts the correct positioning of the microphone at the corner of the mouth, with a recommended distance of 13 mm (0.5 inches) from the mouth to minimize plosive sounds.

Wearing the Microphone

Follow these steps for optimal microphone placement:

Install the windscreen on the microphone boom.
Place the headband around the back of the head, ensuring the boom is positioned on the left side.
Position the microphone at the corner of your mouth. To reduce popping and plosive sounds, avoid placing the microphone directly in front of the mouth.

Note: To maintain the microphone's condition, avoid storing it in damp, enclosed spaces. Allow any perspiration to dry completely before storage.

Technical Diagrams and Charts

The document includes graphical representations of the microphone's performance characteristics. Polar pattern charts demonstrate the cardioid pickup pattern at different frequencies (125 Hz, 1 kHz, 5 kHz), showing sound sensitivity relative to angle. A frequency response chart illustrates the microphone's sensitivity across the audible frequency range from 20 Hz to 20 kHz.

Note on Measurements: Specifications are typically measured using a Shure RPM626 preamp and a 48 Vdc phantom power supply. The microphone can operate at lower voltages, but this may result in slightly reduced headroom and sensitivity.

Certifications and Compliance

Testing for specifications is based on the use of supplied and recommended cable types. The use of cable types other than shielded (screened) cables may negatively impact EMC performance.
