$30.75

The TSA9840B is a 2x20W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It features perfect class-D architecture (based on the MAX98400A), with each channel capable of delivering 20W of power output. Both channels are capable of outputting nominal power simultaneously and continuously. Any DC 10V-24V power supply can power this board and is compatible with two 8Ω passive speakers. The TSA9840B can also be connected to our TSA1000, TSA1010, or TSA1020 external audio volume control boards, allowing users to adjust the audio volume by rotating a real knob.

2 x 20W Class D Bluetooth Audio Amplifier Board – TSA9840B (TWS/Apt-X)

The TSA9840B is a 2x20W audio amplifier board with a new AudioB plus Bluetooth module that supports Apt-X. It features perfect class-D architecture (based on the MAX98400A), with each channel capable of delivering 20W of power output. Both channels are capable of outputting nominal power simultaneously and continuously. Any DC 10V-24V power supply can power this board and is compatible with two 8Ω passive speakers. The TSA9840B can also be connected to our TSA1000, TSA1010, or TSA1020 external audio volume control boards, allowing users to adjust the audio volume by rotating an actual knob.

The highlight is the support for Apt-X and TWS, enabling users to stream audio wirelessly to two paired amplifier boards simultaneously. This board is perfect for Hi-Fi applications and can be paired with a mobile phone, computer, or other compatible devices. Use your phone or PC to search for a new Bluetooth device to power the amplifier board. The module will appear as “TSA9840B”. You don’t need a PIN; pair it, and then you can start playing music.

  • The TSA9840B can automatically detect aux/Line-in audio input; the Bluetooth Audio source has a higher priority. When Bluetooth audio is paused, or the connection is disconnected, the amplifier switches to outputting the aux/Line-in audio.
  • TWS mode is supported. Users can stream audio to 2 paired amplifier boards simultaneously via a wireless connection.
  • The TSA9840B features an extra LINE OUT audio output jack, which can be connected to a subwoofer amplifier board.
  • BVC Port: The BVC port can be connected to our Audio Volume Controller to adjust the Bluetooth audio volume.

TSA9840B can automatically detect the Aux in/Line in Audio input. The Bluetooth Audio source has a higher priority. When Bluetooth audio is paused or disconnected, the AAmplifierwill output the Aux in/Line in audio.

TSA9840B + TSA1000, Both Aux-in and Bluetooth audio volume can be controlled through the BVC port

Two boards work in TWS mode.

  • S1 – Long press 3s into pairing mode. Long press 6s to clear the pairing info.
  • S1+S2 – Long press 1s to enter TWS slave mode.
  • S1+S3 – Long press 1s to enter TWS master mode.
  • S2+S3 – Long press 1s to disconnect the TWS connection.

Shipping Policy

Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they are fast, reliable, and easily trackable. We process orders within 24 hours, and delivery may take 4-7 business days after that, depending on your location. We will email you the tracking number once your order is shipped.

Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated based on product weight, not quantity. To reduce shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before placing your order. We show shipping rates on the product page under the SHIPPING tab. To view the shipping cost for your country, click 'Add to Cart' on the product page.

Return Policy

All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations require reverse tariff payments and multiple shipping fees, which are very costly and time-consuming. For technical issues, we will be happy to assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.

Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund. But we will offer an exchange for a product that has irreversible manufacturing defects or technical problems. If you purchased the wrong product, then you, as the customer, will be responsible for the re-shipping fees and tariffs.

We’re here to help you buy the hottest products affordably, with fast shipping and World-Class Customer Support. However, please read about the newly imposed tariffs and click the Delivery tab to review our Return and Refund policies before making a purchase.

Tariff: We ship directly from the country where the product is made, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs. Since we do not always ship products to you from the USA (except for products made in the USA or stocked), you will not be affected by the new tariffs imposed by the USA. Due to new tariff agreements between countries, not all products are subject to tariffs, as tariffs vary by country or product. For example, customers in the USA will pay a tariff on products imported from China, based on the tariff rate agreed between the USA and China. And so, if applicable, you, the customer, will pay the tariff in your respective country. The total amount of your order does not include a tariff, which you will pay before the delivery. We won’t issue a refund if you don’t pay the tariff.

Or call DHL at 1-800-225-5345  (toll-free) or +603 7964 2800 (overseas). Contact DHL: https://mydhl.express.dhl/us/en/help-and-support.html#/contact_us.

Tariff via USPS: Click the Order Tracking link in the email we sent you to view your tracking number, or call 1-800-ASK-USPS (1-800-275-8777).

Ships From: On this product page, check the Ships From: label to see which country we will ship this product from, because we do not ship all products from the USA; some products ship from regions like China, Taiwan, Canada, and Europe. Therefore, the tariff you pay depends on the country your order is shipped from, as not all countries charge the same tariff. For example, suppose the US imposes a 30% tariff on goods imported from China; in contrast, other countries may impose a significantly lower tariff, or even none at all, on goods shipped from China into their countries.

Attention! We will email you the tracking number for you to track your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff. However, as the customer, you are responsible for responding to their call, text, or email. You can also click the tracking number link we emailed you to contact the shipping company and make the tariff payment, if you haven’t already.

Heads Up! We’re not responsible for parcels returned to us if you don’t pay the tariff or fail to follow up with the shipping company. As a result, if the shipping company returns the parcel to its country of origin, you will be responsible for re-shipping costs and tariff charges. We will not accept any excuses for not paying the tariff or for failing to follow up with the shipping company for the tariff, and we will not issue a refund.

Why are we not adding tariffs to the product’s retail price? If all countries imposed the same tariff amount and used the same currency, we would have added that tariff to the product’s retail price. Our suppliers and we are not responsible for tariffs. Please shop accordingly.
