Volume Control Rotary Potentiometer Board for TAS5756 / TAS5754 Amplifier Board



CS5343 Analog to I2S Decode Board




This stereo mid-power digital audio amplifier board is capable of delivering 30W output power per channel into a 4Ohm load based on Class D topology and Texas Instruments TAS5754 chip, featuring high efficiency up to 90% and high sound quality with low distortion and low noise level. AA-AB32256 supports 3-wire I2S input, suitable for connecting with Raspberry Pi in DIY applications. Compact size, easy installation and mid power output makes this audio amplifier board suitable for home audio, car audio and demanding industrial applications. Besides amplifier board, AA-AB32256 can work as a high performance DAC. A DC10V – 24V power supply is required.

Digital Input and High Quality Audio Performance

By means of dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches 102dB and THD+N performs well as 0.005% @ 4Ohm, 1W, 1kHz. This amplifier board supports I2S digital input and supports high resolution playback up to 192kHz/24bit so customers can enjoy music same as originally recorded.

High Performance DAC

In addition to speaker output, AA-AB32256 provides analog output without amplification, which means you can use this board as a high performance DAC. One board, multiple applications, which is highly cost-effective.

Supporting Power Battery

This audio amplifier can be powered by batteries, greatly improving the portability of the audio system. Thanks to the low power consumption, it features long playback time with WONDOM battery board (BCPB Series). It is suggested to use BCPB3 / BCPB4 to power this digital audio amplifier.

External Volume control

This mid-power amplifier board supports external volume control rotary potentiometer board (AA-AB41152). You can adjust volume through the potentiometer board. Please note that specialized program is needed to be burned for use with TAS5754 / TAS5756. Therefore, the potentiometers in WONDOM VC series can not be used with this audio amplifier board.

High Reliability and Long Service Time

Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Full protection circuit, like over temperature protection, overcurrent protection, over / under voltage protection, is equipped on this board for high reliability and long service time.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. This board is in 3.6’’ x 2.7’’ compact size, which can be easily integrated into any audio projects without occupation of too much space.

Salve vorrei sapere se posso collegare in mono i due canali. Se si, vorrei sapere la potenza che otterrei sul canale mono, con 4ohm e con 8 ohm. GRAZIE Vorrei collegarlo a JAB5(per i woofer) e questa scheda la utilizzerei in mono per un TWEETER da 8ohm. Vorrei sapere se è fattibile. Cosa mi consigliate di fare?

Hello, Matteo. Thank you for your interest in our products. 2x30W TAS5754 cannot be configured as mono mode. The output power is around 30W per channel @4Ohm, 19V and 20W per channel @8Ohm, 19V. Wish this could help you. Have a nice day~

I bought AA-AB32256 with Volume rotary control connected to a Raspberry Pi Zero 2 w. Everything works fine but the Volume control is not synchronized with PI. When you check the volume on AA-AB32256 it is that of the card, nothing changes via the software. I would like to make sure that the controls are connected in such a way that by remotely controlling, when you turn the volume down or up, the level is the same on AA-AB32256 as well. Having control over the board by having a Pi connected without having this opportunity doesn't make any sense

Hello, Massimo. Volumio is usually used as the music player for RaspBerry Pi. It supports software volume control. However, it doesn't support synchronize with hardware. Wish this could help you. Have a nice day~

Hello can the potentiometer J5 increase and decrease sound level ? Or is the sound at max level with noting connected on J5 and only lowered when potentiometer is used ? Which sound level is controlled ? The amplified one or also the 0dB output ? Best regards Stephan

Hello, Stephan. Thank you for your interest in our products. The volume is at its max level when the external potentiometer isn't connected to J5. So, the function of the potentiometer is to decrease the volume, which is mainly achieved by configuring the register of TAS5754. The default output of the amplifier board is 0dB. Wish this could help you. Have a nice day~

Hello, I cannot connect the TAS5754 amplifier to JAB5 via i2S. even with MCLK disabled. Lots of crackling noises and interference. Both boards are powered by BCPB4. Help me please.

Hi, MAXIM. For connecting TAS5754 with JAB5, please check the following points. 1. Since TAS5754 is a slave device, please set JAB5 as master mode. 2. Please make sure the program in JAB5 is the original firmware. 3. For I2S connection, it is suggested to use the ribbon cable for better audio quality. If there is still problem, please kindly send some videos or pictures to us so that we can pinpoint the problem and solve for you. Wish this could help you. Have a nice day~

Good evening, the board is usable with i2s of normal Tinkerboard and not S version

Hi, Paolo. Thank you for your interest in our products. This TAS5754 board supports I2S input and can be used with Raspberry Pi. As for the normal Tinkerboard you mentioned, we didn't have a try. Wish this could help you. Have a nice day~

Hello. May you confirm me that I can use the AA-AB32256 with my "ARYLIC UP2STREAM PRO V3 Récepteur WiFi 2.4G Bluetooth 5.0 vers I2S SPDIF Multiroom 24bit 192kHz". And if yes, how I have to connect the I2S link on the 2 sides ? Kind regards.

Hello, Didier. The product you mentioned cannot be used with AA-AB32256 - TAS5754 as the sample rate of the AA-AB32256 - TAS5754 is 44.1kHz - 48kHz while that of the product is 192kHz. Wish this could help you.
