Microphone Amplifier Module Small Signal Amplification Circuit Module 3.5mm Interface Compact Size YTQ

3.5 mm microphone interface bias and gain module Builtin bias voltage for the 3.5 mm microphone interface. Suitable for electret and other condenser microphones, with a gain of 26.4 dB. This enables proper operation of common mic types without external bias supplies. Power and efficiency. Accepts DC 5–12 V. Builtin boost power module helps preserve dynamic range for clearer sound. Current draw is 43 mA at 5 V and 17 mA at 12 V.Why you need it Provides a readytouse bias source for electret and condenser mics connected via a 3.5 mm jack. Delivers a fixed, clean gain (26.4 dB) to improve signal strength and reduce the need for additional preamps. Supports a wide input voltage range, allowing flexible power options while maintaining performance.What makes it stand out Integrated biasing and boost power module in a compact 3.5 mm interface solution. Consistent bias and gain across a 5–12 V power supply, enabling reliable operation with various devices.Compatibility and performance Compatible with electret and other condenser microphones that use a 3.5 mm interface. Provides a stable 3.5 mm mic bias and a defined gain to improve microphone performance in typical recording or communication applications.Use scenarios Home or office recording: connect an electret or condenser mic to a computer's 3.5 mm mic input to capture clear voice with minimal external power requirements. Video production: power and bias a condenser microphone when using a camera or portable recorder that accepts a 3.5 mm mic input, helping maintain consistent audio quality during shoots. Streaming or conferencing: use with a standard 3.5 mm mic to achieve reliable mic bias and gain, improving intelligibility in online meetings or broadcasts.Notes Power the unit with a DC supply within the 5–12 V range to ensure proper biasing and dynamic range.
