Deltaco RTA-M Measurement Microphone

The Deltaco RTA-M is a professional measurement microphone engineered for precise acoustic analysis and room tuning. This omnidirectional condenser microphone is designed to integrate seamlessly with real-time analyzers, allowing users to capture accurate frequency response data. It serves as a vital instrument for sound engineers and audio technicians who require reliable performance to calibrate audio equipment, optimize sound systems, and achieve balanced sound reproduction across diverse acoustic environments.

Advantages

The primary strength of the Deltaco RTA-M lies in its ability to provide consistent and accurate data collection for acoustic measurements. Its omnidirectional polar pattern ensures that sound is captured equally from all directions, which is critical for room equalization and analyzing the interaction between speakers and the listening space. The robust construction ensures durability during frequent transport and setup, while the high-quality condenser capsule delivers the sensitivity required for professional-grade audio analysis.

Suitable for

• Room acoustic analysis and calibration
• Optimizing sound systems in venues
• Frequency response measurements
• Setting up professional audio monitoring environments

When it may not be suitable

This microphone is specifically designed for measurement and analysis purposes and is not intended for recording vocals or musical instruments. It does not feature the character or frequency shaping typically desired for studio recording applications.

Key specifications

• Microphone type: Omnidirectional condenser
• Application: Acoustic measurement and room tuning
• Compatibility: Real-time analyzers
• Design: Professional measurement grade

How to use

To use the Deltaco RTA-M, connect the microphone to a compatible real-time analyzer or audio interface equipped with phantom power. Position the microphone at the primary listening position or the specific location where you wish to analyze the sound field. Ensure the microphone is oriented correctly according to the requirements of your measurement software. Run the calibration sweep or pink noise generator through your sound system and observe the frequency response data on your analyzer to make necessary adjustments to your equalizer or room treatment.

What to consider before purchase

• Ensure your audio interface or analyzer provides the necessary phantom power
• Verify that your measurement software supports omnidirectional measurement microphones
• Consider the need for a microphone stand for stable positioning during measurements

Usage recommendations

For the most accurate results, perform measurements at multiple points within the room to account for standing waves and reflections, and always ensure the microphone is placed at ear level in the primary listening position.
