Aboiled For Enhanced Audio Quality SSM2167 Microphone Preamplifier Module Compressor Limiter Noise Gate Dynamic Processing

For this function, it is superior to using an operational amplifier in the preamplifier circuitry. Compressing the dynamic range of the microphone signal reduces signal levels and adds extra gain to low-level signals The SSM2167 is a low-voltage, low-noise mono microphone preamplifier, ideal for low-power audio signal chains This preamplifier includes built-in compression and noise The noise gate attenuates the signal level below a certain threshold so that only desired signals such as speech are amplified, and noise in the output signal is reduced These features help improve the clarity of the speech signal received by the microphone.
