Dear visitor,
the majority of our deliveries are made abroad. Orders are usually shipped the same day. With Corona, however, the times for shipping per country have increased considerably. Many customers view this with great impatience.

We have therefore decided to interrupt sales in December to wait until the situation has eased. Since paypal as payment processor does not want to be able to distinguish between different countries of the buyers, the sale has to pause for all countries - the buy buttons are deactivated.

We wish you a contemplative and healthy christmas time and hope to welcome you again as a customer in January 2021.

nos bridge for TDA1540

As a replacement for the digital filter SAA7030 to operate the TDA1540 without oversampling. The digital signals are attenuated in the module and adapted to the TDA1540.

•  attenuated nos bridge 14 Bit

no oversampling TDA1540

Installation
•  Digitalfilter SAA7030 desolder
•  attenuated nos bridge solder in

no oversampling TDA1540

•  disconnect SAA7000 pin16 from the trace
•  connect pin16 with 1kOhm resistor to pin18

With the USB-in module, the nos bridge is not required

As a replacement for the digital filter SAA7220 to operate the TDA1541 without oversampling. The digital signals are attenuated in the module and adapted to the TDA1541.

•  attenuated nos bridge 16 Bit

no oversampling TDA1541

Installation
•  Digitalfilter SAA7220 desolder
•  attenuated nos bridge solder in

no oversampling TDA1541

Depending on the CD player and the position of the clock quartz, an additional cable connection must be made. Use a multimeter to check whether there is a connection from XSYS (nos bridge) to the decoder chip. The corresponding pin on the decoder can vary depending on the CD player.
Dekoder 7210 (dil) - pin18
Dekoder 7310 (dil) - pin18
Dekoder 7310 (qfp) - pin25

If the digital mute is to be used further, there must be a connection between the mute (nos bridge) and the decoder.
Dekoder 7210 (dil) - pin11
Dekoder 7310 (dil) - pin11
Dekoder 7310 (qfp) - pin18

With the USB-in module, the nos bridge is not required
