Shure A900-CM Microphone Specification

The Shure A900-CM Microphone is designed for professional audio applications, offering exceptional sound quality and durability. This condenser microphone features a cardioid polar pattern, which effectively isolates the desired sound source while minimizing background noise and feedback, making it ideal for both studio recording and live performances. The frequency response range of 20 Hz to 20 kHz ensures accurate sound reproduction across the entire audible spectrum, capturing vocals and instruments with precision. The A900-CM is equipped with a high maximum SPL handling capability, allowing it to manage extremely loud sound sources without distortion, which is crucial for capturing dynamic performances.

Constructed with a durable metal chassis, the microphone is built to withstand the rigors of heavy use, offering longevity and reliability. The integrated shock mount system minimizes handling noise and vibrations, providing clear and uninterrupted audio capture. The microphone is designed with a standard XLR connector, ensuring compatibility with a wide range of professional audio equipment. Additionally, the low self-noise characteristic of the A900-CM makes it suitable for critical recording environments where clarity and detail are paramount.

The A900-CM also features a switchable high-pass filter, which reduces unwanted low-frequency rumble and proximity effect, enhancing the clarity of the recorded audio. This microphone is powered via phantom power, requiring 48V to operate, which is commonly provided by most professional mixers and audio interfaces. The Shure A900-CM Microphone combines advanced audio technology with rugged construction, making it an ideal choice for professionals seeking high-quality sound capture in a versatile and robust package.

Shure A900-CM Microphone F.A.Q.

What is the optimal placement for the Shure A900-CM microphone in a recording studio?

For optimal placement, position the Shure A900-CM microphone about 6-12 inches away from the sound source, slightly off-axis to reduce plosive sounds. Ensure it is placed in an environment with minimal background noise and appropriate acoustic treatment for best results.

How can I connect the Shure A900-CM to a computer for recording?

To connect the Shure A900-CM to a computer, use an XLR cable to connect the microphone to an audio interface with phantom power. Then, connect the audio interface to the computer via USB or Thunderbolt, and configure your recording software to recognize the interface as the input source.

What should I do if the Shure A900-CM microphone is not picking up sound?

First, check all cable connections to ensure they are secure. Verify that the audio interface is powered on and phantom power is enabled. Test with a different cable or audio interface if available. If the issue persists, consult Shure support for further assistance.

How do I clean and maintain the Shure A900-CM microphone?

To clean the microphone, gently wipe the exterior with a soft, dry cloth. Avoid using any chemicals or liquids. Regularly inspect the grille for dust buildup and use a can of compressed air to remove debris. Store the microphone in a protective case when not in use to prevent damage.

What are the common causes of audio distortion when using the Shure A900-CM?

Common causes of audio distortion include incorrect gain settings on the audio interface, positioning the microphone too close to the sound source, and insufficient power supply. Ensure proper gain levels and maintain the recommended distance from the source to avoid distortion.

Can the Shure A900-CM be used for live performances?

Yes, the Shure A900-CM can be used for live performances. Ensure that it is properly connected to a mixer or PA system, and utilize shock mounts and pop filters to minimize handling noise and plosives during the performance.

How do I reduce feedback when using the Shure A900-CM in a live setting?

To reduce feedback, position the microphone away from speakers and monitors. Use a unidirectional polar pattern to reject off-axis sound, and adjust the EQ settings to attenuate frequencies that are prone to feedback.

Is it necessary to use a pop filter with the Shure A900-CM?

While not strictly necessary, using a pop filter with the Shure A900-CM is recommended to reduce plosive sounds and protect the microphone capsule from moisture and debris.

What should I do if I experience low output levels with the Shure A900-CM?

Check that the phantom power on your audio interface is enabled, and ensure that the gain settings are correctly adjusted. Try using a different XLR cable to rule out cable issues. If the problem continues, consult the microphone's manufacturer for support.

How do I prevent handling noise with the Shure A900-CM during recordings?

To prevent handling noise, use a shock mount to isolate the microphone from physical vibrations. Additionally, avoid touching or moving the microphone during recordings, and handle cables carefully to minimize noise transfer.
