TSA1702D SPDIF TOSLINK + DSP Audio Receiver Board

$36.08

TSA1702D is an SPDIF + DSP audio receiver board featuring a TOSLINKBee receiver module. The TOSLINKBee converts the SPDIF signal to an I2S signal and outputs it to the ADAU1701 DSP chip. It can accept digital audio sources with different sampling rates, ranging from 16-bit 44.1KHz to 24-bit 96KHz. A micro USB cable or any DC 9V-30V power supply can power TSA1702D.

TSA1702D is an SPDIF + DSP audio receiver board featuring a TOSLINKBee receiver module. The TOSLINKBee converts the SPDIF signal to an I2S signal and outputs it to the ADAU1701 DSP chip. It can accept digital audio sources with different sampling rates, ranging from 16-bit 44.1KHz to 24-bit 96KHz. A micro USB cable or any DC 9V-30V power supply can power TSA1702D.

The main DSP chip on this module is the ADAU1701. Its application spans active loudspeaker concepts (digital 3-way with 3-unit, 2-way with 2-unit crossover, bass enhancement, etc.) and enables the transformation from 2.0 to 2.1 audio systems. It comes equipped with four potentiometers and has a default program loaded. Customers can adjust the gain, bass, midrange, and treble levels. Additionally, it features a debug port for Sigma Studio, allowing users to program this module with our USBi programmer to access additional functions, including equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, and more.

Control Buttons: This function is not supported on TSA1702D.

Potentiometers Port: You can connect external POTs (5K~20K) to control the main volume, treble, midrange, and bass. This is our POT kit.

  • ADC0: Main volume.
  • ADC1: Bass volume.
  • ADC2: Middle volume.
  • ADC3: Treble volume.

Warning: You need to disconnect the soldering pads on the back side of the board when connecting external potentiometers. Otherwise, the ADC port may be damaged. Potentiometer values: 1Kohm-100Kohm.

DSP Programming Port: You can develop a DSP program to meet your requirements and then load the new DSP program using the USBi JTAG Sigma DSP programmer.

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.
