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.

dbx Model 21



the model 21 Disc Decoder is an economical way for you to enjoy the new dbx Disc and Digital dbx Discs. It's even inexpensive enough to use  with a second stereo system in a family room or office.
Just connect the Model 21 to your system and you'll be able to play our complete library of dbx Encoded Discs.  The 21 can also be used to play back dbx encoded tapes which will be available soon.



 dbx Discs are produced using the finest conventional studio master tapes and deliver all their dynamic range. the Digital dbx Discs, encoded from digital master tapes, are the world's first records to reproduce - for a degree of excitement and impact that has to be heard to be believed.
In addition, dbx Discs virtually eliminate the pops, ticks and surface noise that the pops, ticks and surface noise that plague conventional records. For the first time, you can listen to the music, not the record.
dbx Discs and Digital dbx Discs are by far the most extraordinary reproduction of realistic music dynamics available today.
