Audio Distortion Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-M-10482
Jlab Export is a leading Audio Distortion Meter Manufacturer,and suppliers in India
Audio Distortion Meter (code EL-M-10482) is a bench instrument that measures harmonic distortion in audio signals from 20 Hz to 20 kHz, removing the fundamental with automatic nulling and showing the result on an LED readout with 0.1% resolution. A calibrated monitor output passes on the filtered signal for spectral analysis, and the meter is used in testing audio systems. JLab manufactures this distortion meter in Ambala, India.

How the Fundamental Is Nulled
Harmonic distortion is the signal content at whole multiples of the test frequency, expressed as a percentage of the fundamental. The meter filters the fundamental out of the incoming signal; what is left is the harmonic content plus noise, which it shows as a percentage. Automatic nulling locks the filter onto the input frequency within a 15% capture range, and automatic range selectors choose the frequency band, so no hand tuning is needed anywhere from 20 Hz to 20 kHz.
What the Monitor Output Shows
The residue left after filtering appears at the calibrated monitor output. On an oscilloscope it shows the shape of the distortion, for instance a short spike at each zero crossing from crossover distortion in an amplifier, or pulses at the peaks from clipping; on a spectrum analyser it shows which harmonics are present and how strong each one is. The meter’s own residual distortion and noise set the floor below which it cannot read.
Other Audio Distortion Test Instruments
- Low Distortion Audio Generator — low-distortion sine or square oscillator with a digital frequency and amplitude readout.
- Distortion Factor Meter — measures amplifier distortion as a percentage across 20 Hz to 20 kHz.
The meter is filed with other single instruments in Miscellaneous, a part of Test and Measurement Equipment.
