The TSA1452B is a complete audio digital signal processing module. The main DSP chip on this module is ADAU1452. The application range includes active loudspeaker concepts (digital 3-way 3-unit, 2-way 2-unit crossover, bass enhancement, etc.), enabling the transformation from 2.0 to 2.1. It has four potentiometers and a default program loaded. Customers can adjust the gain, bass, midrange, and treble. It also features a debug port for Sigima Studio, allowing users to program this module with our USBi programmer to access additional functions, including equalization, crossover, bass enhancement, multiband dynamics processing, and delay compensation.

Pins define: (Check the board backside silkscreen):

You can also connect our Panel Mount Buttons Kit for Amplifier to TSA1452’s external buttons port; it works the same as the buttons on the board.

Potentiometers port: You can connect external POTs (5K~20K) to control the Main volume, treble, middle, and Bass. This is our POT kit.

  1. ADC0- Main volume.
  2. ADC1- Bass volume.
  3. ADC2- Middle volume.
  4. ADC3- treble volume.

Warning: Disconnect the soldering pads on the board’s back side when connecting external potentiometers. Or the ADC port may be burned. Potentiometers value: 1Kohm-100Kohm.

DSP programming port:

TSA1452’s DSP detects both Bluetooth signal and Line-in signal, but the default program gives Bluetooth a higher priority. If a Bluetooth signal is detected, TSA1452 will output the Bluetooth audio source; otherwise, it will output the Line in audio source. You can develop a DSP program to fulfill your requirement, then load the new DSP program by using the USBi JTAG Sigma DSP programmer.

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.

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.

Tariff via DHL: Click https://www.delivery.dhl.com/on-demand-delivery.xhtml?ctrycode=US or click on the Order Tracking link we emailed to you with your tracking number. 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 UPS: Click the Order Tracking link we emailed you with your tracking number, or call UPS at 1-800-742-5877.

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.
