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.

Denon DP-1200 turntable

 Model DP-1200 has combined an automatic arm lift for easy operation with the high performance Denon servo controlled direct drive record player. The automatic arm lift is accomplished by a non-contact type record end sensor, without affecting the motor torque or tonearm motion.
Model DP-1200 is a unique record player system featuring other facilities such as tonearm height adjustment or standby switch for cueing start.
The electronics circuit is simplified by use of servo IC or speed selector and start/stop by switches of machanical holding type without employing semiconductor memory circuit.
 Model DP-1200 direct-drive record player, with the Denon servo control system by detecting speed with magnetic pulses, is provided with automatic arm lift  for the easy of operation without deteriorating its performance. Although it is provided with the automatic arm lift, the power of the phono motor is not utilized for lifting the tonearm. Model DP-1200  is a high performance record player with the unique Denon technology  realized on such parts as the non-contact type recordend senser, the adjustable tonearm high, the stand-by switch for starting after a cueing , and howling prevention.
