Product Details

ZOUDIO AIO4CH TAS5825M Amplifier Module


High performance speaker building has never been easier. Modern technology makes a powerful combination of amplification and signal processing possible. The compact form factor allows installation in nearly every speaker. Besides long-range Bluetooth streaming, a wired input is supported. The amplifier accepts a wide range (5 – 24 VDC) of power supply voltages. The low idle power consumption makes it ideal for battery powered applications.


The ZOUDIO AIO4CH delivers high quality sound thanks to two TAS5825M amplifier chips from Texas Instruments. The TAS5825M amplifier chip is the successor of the well-known TPA311x. Modern technology improved performance and adds new useful features. The integrated DSP-core enables audio processing functionality like an input mixer, equalizers, crossover filters and delays. These and more useful settings are accessed and programmed with ZOUDIO AIO4CH Configuration Tool.

Specifications for: AIO4CH | TAS5825M | Amplifier Module

  • Rated power output (RMS) The electrical power measured in watts (W) that an amplifier can output per channel, without damaging the amplifier or the output signal is çlipped'. RMS = Root Mean Square. 4 x 50 watts at 4 ohms
  • Minimum load Shows the minimum load that an amplifier can control in ohms. A lower impedance of a speaker is not recommended if it is lower than the minimum impedance of an amplifier. An amplifier works best when the impedance of the speaker falss within the impedance range that the amplifier prescribes (for example, 4 to 8 ohms). 2 ohms
  • Efficiency SPEC Efficiency 90 %
  • Signal-to-noise ratio (SNR) Shows the strength level of signal power compares to a level of noise power. Generally, higher values ​​means better specification. -
  • Distortion Measured in Total Harmonic Distortion + Noise (THD+N). The lower this figure, the closer the output of the amplifier will sound to the original recording. 0.05 % THD at 1 kHz, 1 watt

    Heb in de huiskamer een dure lyngdorf versterker staan. Deze miniscule versterker klinkt net zo goed voor een fractie van de prijs. Dit is met recht een audifiele geheimtip.

    Voor een zelfbouw project met actieve aansturing van de luidspreker is dit de ideale versterkermodule. 4 kanalen met filtering per kanaal. Ik gebruik twee kanalen voor de basluidsprekers en twee kanalen voor de tweeters. Met behulp van de software (downloaden van de Zoudio website) zijn de filters snel ingesteld voor het optimale geluid (het is even experimenteren met de software maar die wijst grotendeels zichzelf). Startvolume en het maximale volume stel je in via de software, zo kun je de speakers beschermen. Alle aansluitkabels zitten er bij.
