2 x 50W SPDIF TOSLINK and DSP Amplifier Board – TSA7802D

$54.50

TSA7802D 2x50W 2 channels SPDIF+DSP digital amplifier board with a TOSLINKBee receiver module. TOSLINKBee converts the SPDIF optical signal to an I2S signal and outputs it to the ADAU1701 DSP chip. TSA7802D is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3116D2), and two channels have a 50W power output. All the channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-24V power supply can power this board. It can be used to drive any 4Ω or 8Ω passive speakers.

All the channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-24V power supply can power this board. It can be used to drive any 4Ω or 8Ω passive speakers.

It’s a two channels amplifier board. It has an optical input connector on the board which can accept different sampling rates from digital audio sources, from 16bit 44.1KHz to 26bit 96KHz. The highlight point is the ADAU1701 DSP chip on board. Users can set each channel’s audio tones separately.

  • External Buttons port: Not support this function on TSA7802D.
  • Aux in enable port: The default DSP program mixes the RCA/Bluetooth audio and output to the amplifier chips. If you want, select the RCA/SPDIF manually by a switch. You can connect an external switch to this port and load a different DSP program.
  • POT port: The user can connect an external 10K potentiometer to control the audio volume.
  • DSP programming port: The user can load a new DSP program by using the USBi JTAG Sigma DSP programmer

The onboard default DSP program will mix the RCA&SPDIF audio and output to the speakers. Users can also change the DSP program to let the audio source be selectable by an external switch.

WE SHIP WORLDWIDE: We primarily ship via FedEx, UPS, DHL, and USPS because they’re reliable, fast, and easily trackable. We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, the delivery may take about 7 to 10 business days, depending on the shipping destination, logistics, weather conditions, product weight, size, or shipping company distribution structures.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. To benefit from lower shipping costs for orders with multiple items, please contact us at sales@ozrobotics.com. Our shipping rates are listed clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country. The total amount for your order does not include a customs fee/tariff. The United States Customs and Border Protection (CBP) deducts import tax, or customs duty, on goods valued over $800 USD from customers located in the US. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
