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.

metronom 2.0 for TDA1540

The metronome-module is used under the TDA1540 converter. In the second version, the module with a lower overall height is easier to use in a small installation space. Due to thinner pins, the board does not need to be re-drilled in some CD players. There was nothing to improve on the tried and tested circuit of the predecessor.

•  Synchronized oscillators of the TDA1540
•  Dynamic correction of the shift register
•  Frequency compensation of the TDA1540
•  Class A operation of the TDA1540

2 metronom 2.0 14 Bit

metronom TDA1540
Installation
•  Desolder TDA1540 or existing socket
•  Solder in metronom-module
•  Remove components at pin8 and 9 in the CDP
•  Insert the TDA1540 into the modules

Notes:
A short circuit between pin7 and 8 will destroy the module under operating voltage. All modules undergo an electrical test before being dispatched.
The module can be used with or without a digital filter.


metronom 2.0 for TDA1541

The metronom-module is used under the TDA1541 converter. In the second version, the module with a lower overall height is easier to use in a small installation space. Due to thinner pins, the board does not need to be re-drilled in some CD players. There was nothing to improve on the tried and tested circuit of the predecessor.

•  Synchronized oscillator of the TDA1541
•  Dynamic correction of the shift register
•  Class A operation of the TDA1541

1 metronom 2.0 16 Bit

Installation
•  only TDA1541A, insert the solder bridge at the bottom
•  only TDA1541A, Interrupt the trace at pin 4 in the CDP

•  Desolder TDA1541 or existing socket
•  Solder in the metronome-module
•  Remove components at pin16 and 17 in the CDP
•  Insert TDA1541 in the module
