1 Η ιστορια της εταιριας ξεκινα το 1900 οπου ιδρυεται απο τον Christian Steidinger στην πολη ST.Georgen η εταιρια Brothers Steidinger η οποια κατασκευαζει οδηγους ελατηριων μηχανικων μοτερ για γραμμοφωνα και μουσικoυς κυλινδρους. Το 1912 κατασκευαζει το πρωτο διπλο μοτερ το οποιο ειναι συνδιασμος ηλεκτρικου και μηχανικου μοτερ ελατηριων.εδω αλλαζει και η ονομασια της εταιρειας σε DUAL κατασκευαζοντας μηνιαιως Διπλα μοτερ. To 1937 η DUAL Turntables κερδιζει βραβειο στην Διεθνης Εκθεση στο ΠΑΡΙΣΙ για το γραμμοφωνο με το διπλο μοτερ. Το 1949 παρουσιαζει το πρωτο πικ-απ με την ονομασια MODEL 1000 κατασκευαζοντας συσκευες ετησιως.

2 Το 1952 κατασκευαζει το πρωτο πικαπ με κρυσταλλικη κεφαλη και απο το 1956 ξεκινα η παραγωγη φορητων πικαπ με ενσωματωμενο ραδιο-ενισχυτη και ηχειο DUAL produces their own crystal phono cartridge that have a tracking force of 6 grams The first DUAL compact unit is introduced. This has the turntable, amplifier and speakers all in one cabinet. The 1950's are marked as years of great technological advancement in the development of music reproduction The introduction of Stereophonic sound! In the spring, DUAL introduces stereo turntables that come with their cartridges Turntables with four pole motors and idler wheel drive are introduced. DUAL invents a record stabilizing system where records could be stacked for multiple play without a record stabilizing arm on the top of the record stack. DUAL introduces the 1006 turntable Automatic sensing of record size is introduced on the DUAL 1008 turntable The first automatic high-fidelity turntable with record changing capability was introduced as the DUAL This unit was the first to be sold world wide. The precision ball bearing mounted tonearm with a tracking force of only 0.5 grams was introduced. As a result of the lower friction of this new tonearm, Anti-Skating became available DUAL introduces the model 1019 turntable with the tonearm set in a universal bearing mount. The Anti-Skating mechanism now tests at near zero skating force! The silicone dampened tonearm lift was introduced and would now become the standard for all future DUAL turntables. With the invention of high-fidelity, the engineers at DUAL set out to set new standards in the reproduction of high-fidelity sound Despite the competition from other vendors of audio equipment and also from Color Television, DUAL continues to do well in the marketplace Four pole synchronous motors are used and the turntable now starts when the tonearm is taken off the rest. This feature appears on the model 1219, which is introduced. This outrageous technology was responsible for the fact that the operator of the turntable could make " operational errors" in the handling of the unit, but no damage to the turntable itself would occur! DUAL purchases P+E (Perpetuum-Ebner) a competitor.

3 DUAL develops the first European Direct Drive Turntable, the DUAL 701. Simultaneous damping of the tonearm resonance from the spring suspension by using a elastic connection. The solution was a two part anti-resonator which is adjusted to a specific frequency. Together they produce a mass to balance the tonearm system The official introduction of Quadraphonic sound during the electronic trade show in Berlin, Germany. DUAL introduces a complete line of Quadraphonic equipment DUAL completes the development of the first DUAL cassette player, the model C-901 and begins production of this unit. The technical features are:auto-reverse Self Degaussing Automatic Adjustment of the Double Gap Erase Heads Horizontal and Vertical Operation Direct Function Switching Dolby B Noise Reduction The first belt drive high-fidelity automatic turntable with the Vario-Belt drive system is introduced. An eight pole motor capable of 78 RPM is also introduced The first hi-fi cassette recorder with a front-load system, the DUAL C-819 is introduced. It also had a fader control and could use all three tape types, photoelectric controls. Facilities for mixing from a microphone and other sources were built in. The name "DUAL International" became well respected by both consumers and audio critics world-wide The first DUAL Quartz controlled turntable with an Ultra Low Mass Tonearm is introduced.

4 It uses a tuning anti-resonator in order to defeat tonearm resonance and a highly stabilized electronic drive system. It also features strobe illumination using LED's and has the controls on the front of the unit. The first remote controlled high fidelity cassette player is the modern C-839RC. This unit is introduced utilizing the latest in microprocessor technology The introduction of the ULM (Ultra Low Mass) tonearm technology. This development resulted in 50% lower mass in the tonearm/cartridge system than other turntables of the time. The advantages to this system are: Better Audible Contact and Better Stylus and Turntable lifetime. The first DUAL Hi-Fidelity receiver with synthesis technology for station scanning and digital frequency display. The "Thermo-Float" technology for DUAL loudspeakers became internationally known Continuing innovation leads DUAL through the 1980's. The introduction of the SM line with Amplifier, Tuner, Receiver, Turntable and Cassette products At the Berlin Electronics show, DUAL introduces the first CD player with PCM technology. Introduction of the successful Hi-Fi Cassette player C-844. This unit offers two motors, two capstans and two speeds. Επισης την ιδια χρονια παρουσιαζει το CS 505 το πικ-απ θρυλος με εκατομυρια πωλησεις παγκοσμιως. On July 1, 1982, DUAL was purchased by the Thompson-Brandt concern. By doing this, DUAL ensured for a long time the quality of their products and that development of these products would continue. The company now was able to acquire the fine technological knowledge and precision of modern micro-electronics In March, DUAL introduces a line of "semi-professional" video equipment.

5 Introduction of the first Hi-Fi video recorder, the DUAL VR The CS-5000 turntable makes its debut. The company now is in the "high-end" audio market. This also marks the debut of turntables being marketed as "DUAL by Ortofon" in conjunction with a marketing agreement with Ortofon, the cartridge manufacturer. The CS-5000 is offered with the OPS (Optimal Pivot System) with tracking angle correction (VTA) and a carbon fiber tonearm head. With this agreement with Ortofon and this offering, DUAL created a new market image DUAL introduces a new marketing concept and changes themselves into a Hi-Fi specialty company. First time presentation of "high end" products at the Frankfurt, Germany Audiophile Show. Perpetuum-Ebner (P+E) (whose turntable business was previously bought out by DUAL) buys DUAL from Thompson Grand Public, of Paris DUAL GmbH becomes affiliated with the German company Schneider Rundfunkwerke AG. The product line was expanded to include television receivers At the International Electronics Show in Berlin DUAL presents themselves as a company specializing in Hi-Fi, Television and Video. DUAL presents the "Studio Concept" line which is intended for consumers interested in the convenient new high technology and excellent reproduction A new "high-tech" television with full digital chassis (DTV-2). It can later be equipped with Nicam, D2-Mac, Multi-Scart, PIP (Picture In a Picture) made for the future. The increasing demand from the former DDR (Deutsch Democratische Republic, or East Germany) results in a market gain for DUAL At the Berlin Electronics Show, DUAL presents an enlarged studio lineup. All components in this line are remote controlled. The MIDI 3700 is introduced, consisting of a complete collection of high tech single components.

6 The crown jewel of turntables has been invented in the form of the "Golden Stone". It's a status symbol with a pebble plinth finish. The high quality of the DUAL turntables (made in Germany) has resulted that other European and even Far Eastern turntable manufacturers have decided to use DUAL-built turntables in their own systems. (OEM) The worldwide recession has resulted in a drop in sales of electronic entertainment equipment. DUAL GmbH and Schneider AG continue until 2001 producing turntables in St. Georgen, Germany for world wide consumption. They continue their OEM business as well. The original DUAL logo is still in use on products made by the St. Georgen firm The Fehrenbacker Company in Germany begins building Dual turntables in St. Georgen, Germany. New turntables are available to day from this company.
