Frequent questions about Next-Lab RTA


Wie funktioniert die Frequenzmessung mit dem Next-Lab RTA?

The Next-Lab RTA from SPL Lab enables precise frequency measurements with its wide frequency range of 10 to 20000 Hz. With the option for calibration either according to Audiomatica CLIO or TERM-LAB, it provides accurate results for professional applications. The microphone features an anodized aluminum housing and highly sensitive, omnidirectional electret microphone inserts that ensure accurate capture of frequencies. The lab bus port for data transmission and an Acoustic Device Chip (ADC) with 16-bit internal accuracy contribute to the efficiency and reliability of frequency measurement.

Welche Amplitudenbereiche kann das Next-Lab RTA messen?

The Next-Lab RTA measures amplitude ranges from 50 to 120 dB, with the High SPL Edition even capable of capturing amplitudes between 60 and 155 dB. This range is particularly useful for analyzing sounds in different environments, from quiet rooms to loud concert halls. Through the finely tuned adjustment of the microphone inserts and the ADC unit, the Next-Lab RTA offers excellent precision in amplitude measurement, supported by calibration to defined standards such as Audiomatica CLIO or TERM-LAB.

Wie wirkt sich die Bauweise des Next-Lab RTA auf die Messung aus?

The construction of the Next-Lab RTA has a direct impact on measurement accuracy. The anodized aluminum housing not only provides robustness but also features that create an ideal acoustic environment. Special notches around the microphone insert achieve a smoother directional characteristic, allowing the input signal to be received as faithfully as possible. The ergonomic design contributes to ease of handling, and the device can be mounted on a stand for more stable measurements, which is particularly advantageous when fine-tuning audio systems.

Welche Funktionen bietet das Next-Lab RTA für Audio-Systeme?

The Next-Lab RTA is designed for a variety of audio functions. It is suitable for measuring and adjusting acoustic systems across the entire audible range, from analyzing the signal waveform to determining the cutoff frequencies for crossovers. It allows for the quantitative assessment of frequency response ripple and the measurement of harmonic distortion coefficients. Fine-tuning of audio system components is also carried out precisely. With the spectral analysis function of a signal, it additionally offers the possibility to optimize acoustic parameters for concerts, vehicles, and living spaces.

Welche Anpassungsmöglichkeiten bestehen mit dem Next-Lab RTA für hohe Schallpegel?

With the High SPL Edition of the Next-Lab RTA, adjustments for higher sound levels are possible, as it can measure amplitudes of up to 155 dB. This feature is ideal for car audio competitions or loud event halls where precise level assessment is required. Calibration according to TERM-LAB supports these high demands. Thanks to the robust aluminum housing and specialized amplifier units, the measurement remains stable and accurate, even at maximum volumes, making the microphone an indispensable tool in the field of professional audio analysis.

Wie wird das Next-Lab RTA kalibriert und welche Vorteile bietet dies?

The Next-Lab RTA is calibrated according to the edition to Audiomatica CLIO or TERM-LAB, which offers the advantage of standardized measurement accuracy. This calibration provides a constant reference for acoustic measurements, especially when analyzing frequency responses and amplitude ranges. The preset calibration simplifies operation, and the user can rely on the fact that the measurement results are consistent and traceable. Especially in professional environments, calibration according to known standards provides a reliable foundation for further acoustic analyses.

Kann das Next-Lab RTA zur Überwachung von Audioqualität in Fahrzeugen verwendet werden?

Yes, the Next-Lab RTA is excellent for monitoring audio quality in vehicles. With its ability to cover frequency ranges from 10 to 20,000 Hz, it allows for detailed measurements of audio systems in vehicles. The ability to control the cutoff frequencies of crossovers and internal filters enables precise sound tuning. The lab bus port facilitates data transfer, allowing adjustments to be made efficiently. The high sensitivity of the electret microphone insert ensures that even minor sound differences can be detected and optimized.

Welche Vorteile bietet der Lab-Bus-Digitalbus des Next-Lab RTA?

The Lab Bus Digital Bus of the Next-Lab RTA offers fast and reliable data transmission, which is crucial for real-time measurements. This interface allows for efficient data exchange between the microphone and other devices, ensuring precise and continuous monitoring of acoustic parameters. This feature is particularly useful in professional applications where accurate and quick measurements are essential. The versatile connectivity optimizes the use of the microphone in different acoustic scenarios, whether in tuning concert halls or in audio-focused vehicles.

Wie kann das Next-Lab RTA auf einem Ständer montiert werden?
