Frequently Asked Questions - M30 Earthworks

How do I connect the Earthworks M30 microphone?

Connect the M30 to any standard XLR input that provides 48V phantom power. Use a balanced XLR cable and ensure the phantom power is enabled on your mixer or audio interface.

What is the frequency response of the M30?

The Earthworks M30 has a frequency response of 30 Hz to 30 kHz, making it ideal for accurate measurements and high-frequency detail capture.

Can I use the M30 for live vocals?

While technically possible, the M30 is designed primarily for measurement and instrument miking. Its omnidirectional pattern may not be ideal for live vocal applications due to feedback susceptibility.

Is the M30 suitable for recording acoustic instruments?

Yes, the M30's flat response and fast transient response make it excellent for recording acoustic guitars, pianos, and percussion with high clarity.

How should I clean the M30 microphone?

Use a soft dry cloth to wipe the exterior. Avoid exposing the diaphragm to moisture. For the grille, gently brush with a soft brush. Do not use compressed air.

What is the maximum SPL the M30 can handle?

The M30 can handle up to 140 dB SPL with 1% THD at 1 kHz, suitable for loud sound sources like drums or amplifiers.

Does the M30 come with a calibration file?

Yes, each M30 includes an individual calibration certificate with measured frequency response data. Some models may include a digital calibration file upon request.

What microphone stand does the M30 require?

The M30 comes with a standard microphone clip that fits 5/8"-27 threaded stands. Use any standard mic stand or boom arm.

How durable is the Earthworks M30?

The M30 is built with a brass body and matte nickel finish, offering durability. However, it is a precision instrument; avoid drops and extreme humidity.

Can I replace the diaphragm of the M30?

The diaphragm is not user-replaceable. If damaged, contact Earthworks support for repair options. The microphone has no user-serviceable parts.

GETTING STARTED

The M30 is a condenser microphone with active electronics. This means:

- Its output level will be naturally higher than many of the dynamic microphones that it may be replacing. It is not uncommon to need to reduce gain if you were previously using a dynamic microphone.

- You will need to engage phantom power on your interface or preamp. Pro Tip: It's always a good idea to plug in a condenser microphone while phantom power is off and the channel is muted. After engaging phantom power, give the microphone a short time to settle before unmuting.

PROPER MAINTENANCE

To guarantee your microphone provides years of performance, follow these guidelines:

- Never attempt to disassemble the microphone - it cannot be opened.

• Avoid extreme heat and condensing humidity.
  Allow the microphone to warm up when bringing it in from the cold.
• Rough handling may damage the microphone even if no markings are visible.
• When not in use, keep the microphone in its case.

IMPORTANT NOTICES

The small tip on many of our microphones allows them to capture the highest frequencies of your sound.

Please be gentle and considerate when handling the microphones with these tips. (Microphones such as the SR314 and SR40V shield the tip within their capsule, and are thus more durable.)

The M30 meets or exceeds ANSI Type 1 requirements.

The microphone is calibrated at the factory at 1 kHz (independent of any frequency weighting).

Earthworks recommends re-calibration every five (5) years.

TROUBLESHOOTING

If you encounter issues while using your Earthworks Audio microphone, please make sure that:

• Your microphone is connected to an active power supply.
• Phantom power is being supplied to the microphone.
• Your microphone and XLR cable are well connected.
• The microphone is positioned at an appropriate distance from the sound source.
• External noise in your recording environment is kept to a minimum.

- Your recording space is at room temperature and free of dust.

If your issue persists after checking, please contact us via our website.
