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.

Hitachi HT-61S turntable

 

Full-Automatic Direct-Drive Turntable

Fully automatic operation with all controls on the front panel provides outstanding convenience in each model; the HT-61S (HT-R10) gives you a few extras. In short, these turntables leave nothing to be desired. This TH-R10 can be used with the RM-1000 remote control center for extra convenience, too.

 

Automatic disc Size/Speed Selection

The HT-61S/R10 uses a light beam to sense the size of the record on the platter and automatically set the lead-in for either 30-cm or 17-cm, so the stylus will lower to exactly the right place. At the same time, platter speed is automatically set to the corresponding speed; 33-⅓ or 45 rpm. This makes operation surer and more convenient, putting the HT-61S/R10 another step above ordinary turntables.

 

All Controls Up Front

All Control functions are located on top of the turntable's front panel. They are accessible when the dust cover is down, preventing the possibility of jarring the tonearm during play. And thanks to the use of IC logic circuitry, it only takes a feather touch to operate all controls.
