About this item

The Acxico AD828 Stereo Microphone Preamplifier Board is a compact, high-performance module designed for dynamic microphones and musical instruments. Utilizing the AD828 fever op-amp chip, it provides a low-voltage power supply range of DC 3.8V-15V, making it suitable for battery-powered setups. This 3-piece set effectively reduces environmental noise and prevents whistling, ensuring cleaner audio capture for instruments like guitars and erhu.

This preamp board features a two-channel design and is optimized for single lithium battery power. For optimal performance and to avoid interference, it requires a battery or linear power supply; switching power supplies are not recommended. The board's small size (2.5x1.6cm) makes it easy to integrate into various audio projects. The on-board resistor R5 can be adjusted to fine-tune magnification for specific audio needs.

For musicians and audio enthusiasts in India seeking to improve their sound quality, these Acxico preamp modules offer a cost-effective way to achieve clearer instrument and vocal recordings. Imported directly, they bypass local market markups, providing authentic performance for your audio setups.

Key Features

  • The piezoelectric ceramic piece is sensitive to the sound wave vibration transmitted by the solid, and is not sensitive to the acoustic vibration of the gas, which can effectively reduce the environmental noise and avoid the whistling caused by the self-excitation. Can be used for guitar, erhu and other musical instruments.
  • Ultra-small volume dynamic microphone preamplifier board,two-channel design,suitable for a single lithium battery-powered,using AD828 fever op amp chip,suitable for low voltage power supply (3.8-15V)
  • If you only used one channel,the other channel needs to short-circuit the input with GND,To avoid interference with the signal crosstalk.
  • Working voltage:DC3.8V-15V.This microphone amplifier board without power regulator circuit,can only use the battery or linear power supply,can not use switching power supply,otherwise there will be interference.
  • Size:2.5x1.6cm/0.98x0.63inch

Why choose this product

Engineered for Clear Audio Capture

This Acxico AD828 Stereo Microphone Preamplifier Board is built with a high-speed op-amp chip, delivering superior amplification for dynamic microphones and instruments. Its design prioritizes signal clarity by minimizing environmental noise and preventing feedback loops, crucial for professional-sounding recordings. The low-voltage operation makes it adaptable for various setups, from studio projects to portable rigs. Imported directly, it offers authentic performance without the typical markups found in local markets, ensuring you get advanced audio technology at a competitive value.

Ideal For Creators, Not For All Setups

This module is perfect for DIY audio projects, musicians seeking to amplify instruments like guitars or erhu, and podcasters needing cleaner dynamic mic input. It's best used with battery or linear power supplies to avoid interference. Avoid using this board with switching power supplies, as they can introduce unwanted noise. If you require a preamp with built-in power regulation or are working with condenser microphones that need phantom power, this specific module may not be the ideal fit.

How to use

  • Connect Power Source — Ensure a stable DC 3.8V-15V power supply, preferably a battery or linear source. Avoid switching power supplies to prevent interference. Connect the positive and negative terminals to the board's power input.
  • Connect Audio Input — Connect your dynamic microphone or instrument pickup to the designated input terminals. If using only one channel, short-circuit the input of the unused channel to GND to prevent signal crosstalk and interference.
  • Connect Audio Output — Connect the output terminals of the preamp board to your audio interface, mixer, or amplifier. Ensure all connections are secure before powering on the system.
  • Adjust Magnification (Optional) — If needed, adjust the on-board resistor R5 to fine-tune the magnification. Larger resistance values (up to 150k ohms) increase magnification. This step is for advanced users seeking specific gain levels.
