Soon afterwards, the station seconded Kolbe to the Wiener Musikverein to record the performances of orchestras such as the Vienna Philharmonic Orchestra and the Vienna Symphony. In 1987, Kolbe said, “We were two Americans, two Swiss and seventeen Austrians and we were heard all over Europe. My department was jazz and modern classical, together with being involved in the design of the studios. We also did a lot of live concerts including one a week from the large concert hall in Vienna, where we used just one microphone, a Shure modified with an AKG capsule and it sounded wonderful!"

Mastertone

From 1951 to 1963 in Vienna, Kolbe operated "Mastertone", his first recording studio. The Mastertone studio was engaged by Vox and Vanguard. Kolbe said, "At that time, the rate of exchange of the dollar to the Austrian Schilling was very favorable and American record companies soon found it well worthwhile to record in Vienna".

In 1987, Kolbe said, "In the autumn of 1953 [we got] the first stereo tape recorder in Europe, an Ampex 350... which meant we aimed for proper stereo image rather than the 'ping-pong' style that was popular in the early days – everything on the left or the right and no middle".Phantom vintage recording 1955 Allied catalog.

Phonag record company

In 1957, Kolbe returned to Switzerland and in 1960 he founded the Phonag Record Company in Winterthur, with the label Helvetia.Lamy A. personal communication. Hotel Rössli, Lindau-ZHMCI 16 track desk. Der Landbote 6 June 1975. The company mainly produced Swiss folklore records. In Winterthur, Kolbe recorded at the Kirchgemeindehaus,Kongresshaus – Kirchgemeindehaus Liebestrasse Winterthur Liebestrasse.ch which had a room with very good acoustics. From 1962, Kolbe's second engineer and apprentice was Robert Lattmann. In April 1966, Kolbe improved his equipment from three small portable microphone mixers without equalizers, dual meters and a ReVox tape recorder to a portable 3-channel tube mixing console, designed and manufactured by Hans Leonhard (Leonhard Electronics, Zürich). This console, which had switchable equalizers co-designed by Kolbe, was used in his studios in Winterthur and Lindau and on most on-location recordings for CBS and Phonag. In October 1966, at the Kirchgemeindehaus in Winterthur Kolbe recorded the Isaac Stern Trio playing the Beethoven Piano Trios, Op. 97, the "Archduke". On 29 June 1970, Kolbe opened a recording studio in Lindau canton, Zürich, Switzerland. The studio measured 161 square meters over two floors. It had a small stage used as storage area. The technical facilities were in a control room with a double-glass window to the studio. Kolbe's first recording console was the modular portable Leonhard valve mixing desk and he used Tannoy integrated concentric coaxial speakers and Studer tape recorders.Studer Studer 1 May 2014. In 1975, the studio was upgraded to a 16 track transistorised MCI desk and Studer A80 8–16 track recorders.

Phonag's rental lease finished on 30 September 1980 and engineer Robert Lattmann entered into a new contract with the hotel as owner of the studio.

By 1980, Kolbe was focussed on acoustics but was still working part-time at the studio in Lindau. According to a brochure of the time, the studio offered 2, 4, 8 and 16 track facilities with the Studer A80 as the master recorder; the 16 track MCI desk, and additional JBL loudspeakers.

Acoustics career

In January 1973, Switzerland left the Bretton Woods system and adopted a floating currency system. This strengthened the Swiss franc in comparison to the United States dollar. Kolbe, being associated with CBS, was affected by the change and this may have influenced him to take his career in the direction of acoustics.Kolbe, C. Personal communication. From 1970, Kolbe worked as an acoustic consultant, designing recording studios, control rooms, concert halls, theatres and multi-purpose halls.Kolbe H.

For instance, he was engaged by the Leonhard electronics company to plan and construct an auditorium for Hoffman-La Roche Ltd., and another for the Bank for International Settlements, both located in Basel, Switzerland.Leonhard H. Personal communication 30 November 2012. Kolbe later said, "By the time the 70s came around I was getting tired of living out of a suitcase and I wanted to spend more time with my family. In a way, everything came together: operas were starting to be recorded on 24 tracks and at this stage I felt that the technology was moving in and the music moving out! Also there was a general slump for classics so I was able to cut down on recording and move back to my first studies, which was acoustics. After all, I had recorded in the best – and the worst – halls in the world and had amassed considerable experience. Whenever I was able to, I measured the halls and began to compile a file on hall acoustics." In 1982, the compact disc was introduced. Kolbe believed the format had been rushed into production.The CD is 30 years old today. What Hi Fi. Although Kolbe continued to contribute to occasional recording projects, from this time, he concentrated on acoustics and control room design.
