2 x 50W + 100W 2.1 Channels Bluetooth Audio Amplifier Board – TSA7492
TSA7492 is a 2x50W + 100W 2.1-channel audio amplifier board with an AudioB Pro Bluetooth module. It features a perfect class-D architecture (based on the TDA7492 and TDA7498), with two channels delivering 50W each and a third delivering 100W. All channels can output nominal power simultaneously and continuously. Any DC 12V-26V power supply can power this board and drive 4ω or 8ω passive speakers. The TSA7492 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.

The TSA7492 is a 2.1-channel amplifier board, with the subwoofer channel providing a 100W mono output. You can pair it with a mobile phone, computer, or other compatible device. Power the amplifier board. Use your phone, PC, or any other device to search for a new Bluetooth device. The module will appear as “TSA7492.” You don’t need a PIN; just pair it, and you can play music.
The TSA7492 can automatically detect the Aux/Line-in Audio input, with the Bluetooth audio source taking priority. The amplifier will output the Aux/Line-in audio when Bluetooth is paused or disconnected.
An audio connector can connect with an external DSP to set the subwoofer audio tones.
BVC Port: The BVC port can be connected to our Audio Volume Controller to control the Bluetooth audio volume.
Subwoofer tones set port:
Connect an external potentiometer to control the subwoofer volume separately.
The TSA1701 controls the subwoofer channel on our 2.1-channel amplifier board.
Buttons Control Port:
The board has three buttons: volume control, play/pause, and other functions. The control port on this button lets you easily connect external buttons.
Pins Definition: (Check the board backside silkscreen)
P/P: Play/Pause button
VOL+: Volume increase and forward button
VOL-: Volume decrease and rewind button
Note: The reference voltage for the buttons is 1.8V.
The TSA7492 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 Amplifier outputs the Aux-in/Line-in audio.
TSA7492 + TSA1000: The Aux-in and Bluetooth audio volume can be controlled through the BVC port.

Shipping Policy
Fast Delivery! We ship via USPS, UPS, DHL, or FedEx because they're fast, reliable, and easy to track. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We'll email you the tracking info once we ship your order. We sell in USD.
Tariff: To minimize or avoid high tariffs, we ship from the country where the product is made, such as China, Italy, Taiwan, Canada, or Europe. If applicable, you will pay the tariff in your country before delivery. Your order total does not include a tariff.
Product Support: You don't need to contact our manufacturer or supplier for support before or after your purchase. We'll help you resolve any technical issues. We answer emails with real people, not AI, chatbots, or community forums!
Ships From: On this product page, check the Ships From: label to see which country the product ships from. We do not ship all of our products from the USA, except for products made in the USA or in stock. We ship most products from regions such as China, Italy, Taiwan, and Europe, as well as other countries. Therefore, tariffs depend on the country of origin, as not all countries charge the same rate. For example, if the US imposes a 30% tariff on goods from China, in contrast, other countries may impose a lower tariff or none at all.
Tariff vs. Shipping Fee: Please don't confuse the shipping fee with the tariff, because they are two separate charges. You pay us a shipping fee for the carrier to deliver your order to your door. You pay the tariff to the customs office, a branch of your government, as an import tax.
Why aren't we 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.
Shipping Costs: For some products, we calculate shipping fees based on weight and package size. Some items ship with batteries, which require special delivery for safety and result in a slightly higher cost. For lower shipping costs on multiple items or bulk orders, please email us the product link, quantity, country, state, and ZIP code so we can help lower the shipping cost. Thank you.
Attention! We'll email you the tracking number so you can follow your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff on their website. As the customer, you're responsible for responding to their calls, texts, or emails. You can also use the tracking number link we emailed you to contact the shipping company or pay any applicable tariffs online, if you haven't already done so.
Heads Up! We're not responsible if the shipping company returns your parcel to the country of origin because of unpaid tariffs or non-compliance with its requirements. As a result, you will be responsible for the reshipping costs, applicable tariffs, and an additional 20% service fee. We will not accept any excuses for failing to follow up with the shipping company regarding the tariff, and we will not issue a refund.
Please check your SPAM folder! To provide you with delivery information, we will add your email address to the shipping website so you receive delivery notifications until your parcel reaches your shipping address. Please always check your spam folder to ensure you receive emails from Oz Robotics, USPS, UPS, DHL, and FedEx. Please let us know if you don't want us to enter your email on the shipping company website.
Return Policy
5 Hours: If a mistake occurs during purchase, you have 5 hours to request a refund for any reason, including if you don't want to pay the tariff. However, Stripe will not refund its processing fee if you cancel your order; therefore, we cannot refund it.
All Sales Are Final: After 5 hours, we can't cancel your order with a refund because order cancellations incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, reverse tariff payments, and paid ads, all of which are costly and time-consuming. For technical issues, we'll help you resolve the problem and provide a replacement if you can prove 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 can't issue a refund, but we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you will be responsible for the reshipping fees and tariffs. If the product is defective, please email us ASAP with photos or a video of the faulty part so we can evaluate the issue before arranging a replacement.

Terms and Conditions
Delivery Date/Time: If the shipping company can't deliver your parcel because you weren't at your delivery address on the scheduled date/time, that is not our fault. If the carrier returned your parcel to the manufacturer from the country where it was shipped, that is outside our control. Therefore, you will be responsible for paying the re-shipping cost and any applicable tariff for any re-shipment request. In such a case, we will not issue a refund.
We know that some customers place an order and then go on vacation. Please note that since Donald Trump ended the $800 de minimis exemption, low-value international shipments no longer enter duty-free. All incoming packages of $800 or less, even for a product costing $1, are now subject to regular country-specific import duties, processing fees, and full customs checks. So even if you are on vacation, you will need to watch your email, phone calls, and texts to pay the tariff before it is delivered to your shipping address.
Warranty: We cover problems caused by manufacturing defects, not those resulting from faulty repair attempts, misuse, or customer accidents.
