2. Safety Instructions
Please read and follow these safety instructions carefully to ensure safe operation and to prevent damage to the device or injury to yourself.
- Power Source: This microphone requires phantom power (48V DC) for operation. Ensure your mixer or audio interface provides stable phantom power.
- Connection: Always connect the microphone to your audio system using a balanced XLR cable.
- Environment: Do not expose the microphone to water, moisture, or extreme temperatures. Avoid placing it near heat sources.
- Handling: Handle the microphone with care. Avoid dropping it or subjecting it to strong impacts.
- Servicing: Do not attempt to service this product yourself. Refer all servicing to qualified service personnel.
- Phantom Power Activation: When activating or deactivating phantom power, ensure that the output levels of your mixer or amplification system are turned down to prevent loud thumps or potential damage to speakers.
3. Features
The BA 19A microphone is equipped with several key features for optimal performance:
- Condenser boundary microphone design for acoustic instruments.
- Optimized frequency response for kick drums, piano, and other bass-heavy instruments.
- Integrated preamplifier for outstanding signal integrity and low noise.
- Half-cardioid polar pattern to minimize background noise and feedback.
- Switchable filters for enhanced low-end presence and high-frequency attack.
4. Setup
Proper setup is crucial for achieving the best sound quality from your BA 19A microphone.
4.1 Connecting the Microphone
- Ensure your mixer or audio interface is powered off or its input gain is set to minimum.
- Connect a balanced XLR cable to the XLR output connector on the rear of the BA 19A microphone.
- Connect the other end of the XLR cable to an available XLR input on your mixer or audio interface.
- Activate 48V phantom power on the corresponding input channel of your mixer or interface. The blue LED around the XLR connector on the microphone will illuminate when phantom power is active.
- Gradually increase the input gain on your mixer/interface until the desired signal level is achieved.

4.2 Microphone Placement
The boundary design of the BA 19A is optimized for placement on a flat surface, which enhances its low-frequency response. Consider the following for optimal placement:
- Kick Drums: Place the microphone inside the kick drum, typically on a pillow or foam, facing the beater for a punchy, full sound. Experiment with distance from the beater head for different tonal characteristics.
- Pianos: For grand pianos, place the microphone inside the lid, facing the soundboard or strings. For upright pianos, placement near the soundboard or inside the bottom panel can yield good results.
- Other Bass-Heavy Instruments: For instruments like bass cabinets or large percussion, place the microphone on the floor or a flat surface directly in front of or inside the instrument's sound projection area.
- General Use: The half-cardioid pattern is effective at rejecting sounds from the rear, making it suitable for stage use where feedback rejection is important.
5. Operating
The BA 19A features a switchable filter to tailor its frequency response to your specific needs.
5.1 Filter Switch
Located on the rear of the microphone (refer to Figure 2), the filter switch allows you to select between two frequency response curves:
- Flat Response: This setting provides a neutral frequency response, suitable for general instrument miking where a natural sound is desired.
- Contoured Response: This setting engages filters designed to enhance low-end punch and high-frequency clarity, often preferred for kick drums and bass instruments to achieve a more "produced" sound.
Experiment with both settings to determine which best suits your instrument and desired sound.
6. Maintenance
To ensure the longevity and optimal performance of your Behringer BA 19A microphone, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the exterior of the microphone. Do not use abrasive cleaners, solvents, or waxes. Avoid getting moisture into the grille or connectors.
- Storage: When not in use, store the microphone in its protective case (if provided) or a clean, dry environment away from dust and extreme temperatures.
- Cable Care: Always disconnect XLR cables by gripping the connector, not the cable itself. Avoid kinking or tightly winding cables.
7. Troubleshooting
If you encounter issues with your BA 19A microphone, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output |
|
|
| Low or weak sound |
|
|
| Excessive background noise/feedback |
|
|
| Loud noise when activating/deactivating phantom power |
|
