Description

This trainer has been designed with a view to provide practical and experimental knowledge of a general circuit of Compact Disk (C.D.) player on SINGLE P.C.B. of size 18″ x 15″.

• The complete circuit of a C.D. Player is printed on a single P.C.B.
• The parts are soldered on single pin tags for easy replacement.
• The digital signal processing section is in assembled open out PCB.

• Explanation, Observation, Alignment and adjustment of Internal and

  external controls is possible due to single P.C.B.

• Easy identification of different parts and Mechanism at a glance.
• Easy measurement of voltages and observation of waveforms at any point.

Also typical voltages and waveforms are provided.

• A manual having practical detail is provided with the trainer.

• The whole circuit of the C.D. Player is explained sectionwise in detail in the

  manual.
