Setup Guide
1. Unpacking and Inspection:
Carefully remove all components from the packaging. Verify that all items listed below are present and undamaged:
- MIPRO MU 55 LS Lavalier Microphone
- Microphone Clip
- Windscreen
2. Attaching the Microphone Clip:
The included microphone clip allows for secure attachment of the lavalier microphone to clothing or other surfaces. Gently insert the microphone into the clip until it is firmly seated.
3. Installing the Windscreen:
For outdoor use or in environments with significant air movement, slide the windscreen over the microphone head. This will help reduce wind noise and plosives, improving audio clarity.
4. Connecting the Microphone:
The MU 55 LS features a 4-pin mini XLR connector. Connect this connector to a compatible wireless bodypack transmitter or audio interface that provides the necessary power (e.g., phantom power if required by the connected device, though this is a condenser mic, it typically works with specific bodypacks). Ensure the connection is secure to prevent signal loss.
Note: Always ensure your audio equipment is turned off before connecting or disconnecting the microphone to prevent potential damage to the microphone or the connected device.
Operating Instructions
1. Microphone Placement:
For optimal sound quality, position the lavalier microphone approximately 6-8 inches (15-20 cm) below the speaker's chin, centered on the chest. This placement helps capture a balanced vocal tone while minimizing clothing rustle.
2. Cable Management:
Route the microphone cable discreetly under clothing to prevent it from being snagged or creating noise. Secure any excess cable to avoid interference with movement.
3. Gain Adjustment:
Adjust the input gain on your connected transmitter or audio interface. Start with a low gain setting and gradually increase it while monitoring the audio levels. Aim for levels that are strong but do not clip or distort, typically peaking around -6dB to -3dB on a digital meter.
4. Monitoring Audio:
Always monitor the audio output through headphones or a speaker system to ensure clear sound capture and to identify any potential issues like background noise or distortion.
Maintenance
1. Cleaning:
To clean the microphone, gently wipe the exterior with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the microphone head or connector. Do not use harsh chemicals or abrasive cleaners.
2. Windscreen Care:
The windscreen can be removed and gently hand-washed with mild soap and water if it becomes dirty. Allow it to air dry completely before reattaching it to the microphone.
3. Storage:
When not in use, store the microphone in a clean, dry place, preferably in its original packaging or a protective case. Avoid exposing it to extreme temperatures, high humidity, or direct sunlight.
4. Cable Care:
Avoid sharply bending or kinking the microphone cable. Coil the cable loosely when storing to prevent damage to the internal wiring.
