Setup Guide

Unpacking

Verify that the following components are included in the package:

• 1 Shure SM35-XLR Headset Microphone
• 2 Windscreens
• 1 Headset Clip
• 1 RPM626 Preamp

Connecting the Microphone

1. Connect the SM35-XLR headset cable to the RPM626 preamp.
2. Connect the 3-pin XLR output of the RPM626 preamp to an XLR input on your mixer or audio interface.
3. Ensure that the connected device provides phantom power (typically +48V). Condenser microphones require phantom power to operate. Refer to your mixer or audio interface manual for instructions on enabling phantom power.

Wearing the Headset

Position the headset securely on your head. Adjust the wireframe for a comfortable and stable fit. The flexible gooseneck allows for precise positioning of the microphone element near your mouth.

Operation

Microphone Placement

Adjust the flexible gooseneck to position the microphone element approximately 1-2 inches from the corner of your mouth. This placement helps optimize vocal capture and minimize breath noise. Experiment with slight adjustments to find the ideal position for your voice and performance style.

Sound Considerations

The SM35-XLR features a unidirectional (cardioid) polar pattern, which primarily picks up sound from the front of the microphone while rejecting sound from the sides and rear. This characteristic is beneficial for reducing feedback on loud stages and minimizing signal bleed from other instruments or monitors.

Maintenance

Cleaning

To maintain optimal performance and hygiene, regularly clean the headset and microphone element. Use a soft, dry cloth to wipe down the headset frame. For the microphone element, gently clean the windscreen. Avoid using harsh chemicals or abrasive materials.

Windscreen Replacement

The SM35-XLR includes snap-fit windscreens designed to protect the microphone element and reduce plosive sounds. If a windscreen becomes damaged or worn, replace it with a new one. Replacement windscreens are typically available from authorized Shure dealers.

Troubleshooting

No Sound Output

• Check Connections: Ensure all cables (headset to preamp, preamp to mixer) are securely connected.
• Verify Phantom Power: Confirm that +48V phantom power is enabled on the mixer or audio interface input channel connected to the microphone.
• Input Level: Check the input gain on your mixer. It may be set too low.
• Cable Integrity: Test with a different XLR cable if possible to rule out a faulty cable.

Feedback Issues

• Microphone Placement: Ensure the microphone is positioned correctly and not too close to loudspeakers or monitors.
• Monitor Volume: Reduce the volume of stage monitors if feedback occurs.
• Equalization: Use an equalizer on your mixer to cut frequencies that are causing feedback.

Distorted Audio

• Input Gain: Reduce the input gain on your mixer or audio interface. The signal may be too strong, causing clipping.
• Microphone Distance: If the microphone is too close to the sound source, it can cause distortion. Adjust placement slightly further away.
