Hi-Fi MINI COMPONENT SYSTEM Trainer Model ETR 023
Hi-Fi MINI COMPONENT SYSTEM Trainer Model ETR 023
HiFi – CD – Radio -System TRAINER
Sci-tech Hi-Fi MINI COMPONENT SYSTEM Trainer Model ETR 023 is an educational instrument designed for the theoretical/practical study of the workings of a MINI COMPONENT SYSTEM player, as well as the operation of DVD-format digital video and audio signals, and digital audio in CD format. The functional structure of the equipment enables its internal composition to be observed, the various signals involved in its operation analyzed by means of a block diagram and faults introduced, all in order to aid the student learn diagnostic methods and how to locate breakdowns.
Item Description
The trainer includes a MINI COMPONENT SYSTEM player using the latest digital signal processing technology, and offering the best features found on the market today. In the training Manual, the theoretical aspects and the description of the circuits are also included basic that compose the equipment.
The instrument is backed up by extensive documentation (which includes a Training Manual, Teacher’s Manual and Technical Documentation Manual), a DVD disk, a CD disk*, an infra-red remote control (batteries included) and an audio/video connector cable.
Using the block diagram, which shows the generic structure of a MINI COMPONENT SYSTEM DVD & CD player, the student can access the main signals involved. The block diagram consists of the following stages:
– Optical Unit (Pickup)
– RF Block
– Servo systems
– Drivers
– Digital Processor
– Video Processor
– Audio Processor
– System Control
– Keyboard,
Remote Control,Display
– Power Supply
The breakdown simulator enables malfunctions to be introduced into the MINI COMPONENT SYSTEM DVD & CD player, thereby simulating a large number of real breakdowns.
