Doehler & Haass Control Systems GmbH & Co. KG is a European manufacturer of command control components.

They make a number of decoders that work with Selectrix SX1 and SX2, as well as NMRA DCC. Many of their products also support Asymmetric DCC.

D&H developed the Selectrix command control system, and are the sole supplier of the ICs required. They shopped Selectrix to various manufacturers in Europe beginning in 1980, with no interest. In 1987 Trix began selling and supporting SelecTRIX under an exclusive marketing agreement.

Company Description

From their website: (Translated from the original German text.)

Since 1975, Doehler & Haass (D&H) has been developing, producing and selling components for the digital control of model railway layouts.

As early as 1982, TRIX was the first series manufacturer to present the "SelecTRIX" system developed by Doehler & Haass. This was a fully functional digital system that already had a load control system that enabled authentic driving operation for the first time. It took many years before competitors were able to offer this decoder technology.

During this time, Doehler & Haass developed a special, customer-specific circuit (ASIC). As early as 1984, it was possible to produce what was then the world's smallest locomotive decoder. Since then, this ASIC technology has been consistently further developed and ensures, among other things, the excellent motor control (Super Soft Drive / SSD)®, which is widely praised by customers.

Doehler & Haass products support all common model railway standards, such as SX1, SX2, DCC, MM, ABC and RailCom. Not only are they represented on the market under the name Doehler & Haass, but well-known manufacturers also incorporate them into their own components (OEM business). The product development is continuously continued and thus offers customers a constantly expanding product range that meets all wishes.

As a special service, Doehler & Haass provides free software updates over several years, as well as the free download of sound projects from the studios of renowned sound designers.

Almost all system components offered are manufactured in Germany. Particular attention is paid to the use of high-quality materials and careful workmanship, which ensures a particularly high level of reliability. And all this at a very attractive price!
