What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

C.E.C. ST-540

Direct Drive Quartz-lock Fully Automatic Turntable
Model ST-540's direct drive and fully automatic operation provide perfection and highest quality. Quartz-lock insures  that the turntable rotation will not vary under changing load or voltage. Rotation precision is maintained at ±0,0001% and rumble has been almost eliminated. Wow and flutter have been reduced to negligible levels by improvements in the direct drive.


The Low mass, straight tonearm, is statically balanced for improved tracability, has a removable headshell and antiskating device. The optional moving magnet (MM) cartridge with diamond stylus assures faithful reproduction for the utmost in listening pleasure.
Acoustic feedback reduced.
Improvements made in the subchassis have greatly reduced acoustic feedback. The independent suspension of the floating chassis improves howling performance and pushing the operation buttons does not move the chassis. The hefty, solid base stands firmly in place when the operation buttons are pushed.

All-front operation.
All operations are by feather-touch buttons located on the panel. Even cueing can be performed with the dust cover closed. Operational simplicity is combined into this convenient arrangement.
Fully Automatic operation
Simply place your favorite record on the platter, close the dust cover and push the button. That is all it takes for this fully automatic turntable. Lead-in is automatic and the tonearm will return to rest and turn off power when the record ends.

Oil-damped cueing.
The delicate stylus needle is gently lowered into the record groove with oil-damped cueing. Thus you are now assured of safer and easier record play with no impact shock when the needle contacts the record.
