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.

Philips GA 212

 Philips GA212
That Philips make Hi-Fi of the highest quality as well as good domestic audio equipment is most clearly demonstrated by the new GA212 „electronic” record deck.
This shows technological innovation of a high order, resulting in genuinely better standards of record reproduction.
Its two speeds (33-1/3, 45 rpm) can be adjusted precisely, using the built-in stroboscopic rings and fine-speed controls, and are accurately maintained by a tacho generator that keeps wow and flutter to less than 0,1%. 
 Speed selection is by „skin-sensitive” controls that light-up when touched.
Floating suspensions of the turntable and pick-up arm gives excellent insulation against shocks and vibration, resulting in very low rumble and very accurate cueing.
Turntable and pick-up arm have been mounted on a sub-chassis which is suspended from the rigidly mounted main chassis. Considerably more flexible springs can therefore be used. And as the motor is independently mounted underneath the main chassis, the pick-up arm is doubly insultated against vibrations from the motor.
the tracking error of the virtually frictionless low-resonance pick-up arm is exceptionally low. Side-thrust may be compensated at all playing weights for both conical and elliptical styli.
The Philips slide-in carrier accepts virtually any pick-up cartridge with fixing centres to the 1/2” international standard. A Philips GP400 Super M magneto-dynamic cartridge is supplied.
 Switching on and off is done silently through a bi-stable multi-vibrator, operated by relay-type switches.
Autostop at the end of a record is not effected by mechanical means, but electronically. When the rate of interception of a ligh-beam striking a photo-sensitive cadmium sulphide cell exceeds a certain value, a bi-stable multivibrator is triggered, cutting off the motor supply voltage. Hence „thumping” and groove jumping cannot occur. The pick-up can be lowered precisely into any groove, even close to the run-out, without premature switch-off.
