AJMRTC SSM2167 Microphone Preamplifier Compressor Module, Low Noise Audio Amplifier Board with Noise Gate, DC 35V Mic Signal Processor for DIY Recording, Speech Input and Audio Maker Projects
- 1. Audio amplifier module centered on SSM2167 chip, integrates microphone preamplifier, signal compression and noisegate to process raw microphone input signals efficiently
- 2. Dynamic compression automatically controls audio peaks, avoids signal clipping, balances loud and quiet voice levels for consistent output volume
- 3. Builtin noise gate suppresses idle background noise, reduces ambient hum when no voice input, enhances vocal clarity for microphone capture scenarios
- 4. Operates at DC 35V low voltage with low power draw, suitable for batterypowered portable audio gear, embedded devices and experimental circuit builds
- 5. Compact finished module with exposed input and output pads, convenient for wiring and modification, great spare expansion board for custom audio equipment assembly

AJMRTC SSM2167 microphone preamplifier compressor module is an allinone analog audio processing board for microphone sources. Using the SSM2167 dedicated audio IC, this unit performs microphone signal preamplification, dynamic range compression and noise gating in a single compact circuit.
The compression circuit smooths out sudden volume spikes to prevent audio distortion, while the noisegate function mutes unwanted background noise during silent periods. Lownoise circuit layout keeps signal distortion minimal to preserve natural vocal quality. Powered by DC 35V supply, this module fits portable batterydriven hardware as well as fixed audio systems. Input and output pads are preexposed for simple soldering connection. Users can adjust peripheral resistor values to alter compression strength and noisegate threshold to match different microphones and usecases. Perfect for voice recording systems, intercom units, custom microphone builds and STEM audio experimental projects. Verify supply voltage and signal compatibility with your peripheral hardware before wiring.
