MAIN KEY FUNCTION

Test index	TWS regular audio	Key function	Unit
Frequency Response	FR	Reflecting the processing ability of different frequency signals is one of the important parameters of audio products	dBSP
Total Harmonic Distortion	THD	The deviation of signals of different frequency bands in the transmission process compared with the original signal or standard	%
signal-to-noise ratio	SNR	Refers to the ratio of the output signal to the low noise generated by the power amplifier during its operation. This low noise is generated after passing through the equipment and does not change the original signal.	dB
Power pair distortion	Level vs THD	The distortion under different output power conditions is used to indicate the output stability of the mixer under different power conditions.	%
Output amplitude	V-Rms	The amplitude of the external output of the mixer at the rated or permitted maximum without distortion.	V
Noise floor	Noise	Noise other than useful signals in electroacoustic systems.	dB
