Product Information

Full details

The RØDE NT45-O is an essential accessory for professional audio engineers and content creators who utilize RØDE NT5, NT55, or NT6 microphones and require greater acoustic flexibility. This gold-sputtered, 1/2-inch condenser capsule captures audio with a wide, natural omnidirectional polar pattern, making it ideal for room ambiance and ensemble recording; however, users should note that its omnidirectional nature makes it highly sensitive to unwanted background noise in untreated acoustic environments.

FAQs

Does the NT45-O require phantom power?

Yes, as it is a condenser capsule, it requires standard 48V phantom power provided by your interface or mixing console.

Can I use this on an NT4 microphone?

The NT45-O is specifically designed for the NT5, NT55, and NT6 series. It is not compatible with the fixed-capsule design of the NT4 stereo microphone.

Is the capsule sensitive to moisture?

Like all high-quality condenser capsules, it is sensitive to high humidity and moisture; keep it stored in a dry environment.

How do I clean the exterior of the capsule?

Use a soft, dry lint-free cloth. Do not use liquids, sprays, or compressed air directly on the diaphragm.

Why does my recording sound 'thin' compared to the cardioid capsule?

Omnidirectional microphones do not exhibit proximity effect (the bass boost when close to a source). Ensure you are positioned correctly to achieve the desired tone.

Troubleshooting

Low output or no signal after installation

Ensure the capsule is threaded fully and making proper contact with the internal pins of the microphone body.

Excessive noise or hiss

Verify that your phantom power (48V) is correctly supplied to the microphone and that your pre-amp gain settings are calibrated for the sensitivity of an omni capsule.

Pros and Cons

Pros

  • Delivers a natural, open audio character for room ambiance
  • Easy to install and swap in seconds
  • Professional gold-sputtered build quality
  • Extends the versatility of existing microphone inventory

Cons

  • Omnidirectional pattern captures more ambient noise
  • Requires a compatible RØDE microphone body
  • Not suitable for sources requiring high off-axis rejection

Setup, Compatibility & Care

Installation of the NT45-O is straightforward: ensure your microphone is powered off and unplugged to avoid potential transients. Carefully unscrew the existing capsule from the top of the microphone housing and gently screw on the NT45-O. Do not overtighten; finger-tight is sufficient. The NT45-O is fully compatible with the RØDE NT5, NT55, and NT6 models. To ensure longevity, always store the capsule in a dry, dust-free environment when not in use and avoid touching the diaphragm directly, as oils from skin can degrade performance over time.
