RTA-420 Microphone Correction Curve Database

Enter your information below to retrieve the frequency response correction curves for your Rational Acoustics RTA-420 microphone.

Please note that correction curves are only available for calibrated RTA-420 microphones. If you do not have a sticker on your microphone displaying a serial number (i.e. RA1125), then it does not have a correction curve file. Correction curves are not interchangeable.

If you are having trouble locating your number or using this form, please try submitting a support ticket.
