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

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
