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.

Braun TG 1000 open-reel deck


The TG 1000 operates in any position, it has a space for a fourth head in its plug-in head assembly. The additional head can be used as 4-track play back head or be used for slide synchronizing. There is a remote control unit TGF3 available for all functions. All US-plugs. All headphones with impedances from 5 - 2000 ohms can be driven to full volume. Sound on sound; echo; tape monitoring are provided. The counter has 4 digits, and the unique new TB 1022 low noise, high output tape eliminates the need for 10,5" reels. The TG 1000 holds 3300 ft of tape om its 8-3/4" reels. The tape drive with the electronic tension control is so gentle and foolproof that even triple play tape may be used. The built in cable driver and the wide dynamic range input circuitry permit flexibility at the interfaces to amplifiers and microphones. The level meters are peak reading for fast response. The robust construction is very compact and fully modular. All circuitry is silicon solid state.
