Practice session in Studios 301:

The Studios

All rooms in Studios 301 have been built with great care in terms of structural and room acoustics. The planning and the acoustic calculations were taken over by the renowned studio designer, Jochen Veith, from the Munich company jv-acoustics. Together with the studio manager and sound engineer, Ulli Schiller, a top-class energetic, artistic production and meeting place was built. The band COLDPLAY, who recorded for three days in the studios in the middle of last year, also felt this special energy.

  • In the large recording room:
    • Recording of an acoustic guitar using the 12/12 method and two main microphone techniques in the primary room (M/S and small AB)
    • Listening to the guitar recording on the Grimm speakers and in the control rooms (secondary rooms)
    • Listening through Bowers & Wilkens Diamond 800 with Nubert Class D amplifiers and Neumann KH320
  • Studio 1 (SSL control room):
    • Mixdown of the song TREIBGUT from the album VIEL ZU VIEL by the artist MARKUS STRIEGL
    • Demonstration of the degree of correlation using an analog meter, a goniometer or a PlugIn using a stereo recording as an example.
    • Listening through Bowers & Wilkins Diamond 800 with Nubert Class D amplifiers and Neumann KH320 studio monitors
  • Studio 2 (API control room):
    • Practical demonstration: Sound influence of the (switchable) group delay correction on monitor loudspeakers using the example of the HEDD Audio Type 20 MKII.
    • Listening through PMC twotwo8 and Neumann KH120 studio monitors
  • Studio 3 (Avid S6 control room):
    • Mixdown demonstration of a multi-track drum recording from Studios 301 with Aaron Spears (USHER / BACKSTREET BOYS / CARRIE UNDERWOOD)

The Speakers

Jürgen Schröder

With more than 30 years of editorial professional experience, Jürgen Schröder is one of the most well-known and distinguished journalists in the Hi-Fi and pro-audio sector throughout the country. Even as a teenager, he was fascinated by the connection between music and technology, leading him down a path towards a career as a drummer in local bands, which he combined with an education as an energy electronics technician. 
From a small sound company, it turned into Jürgen becoming a live sound engineer on tour with well-known artists such as Franz Josef Degenhardt, Lydie Auvray, Hannes Wader, Purple Schulz, Maria Farantouri, Abdullah Ibrahim, and many others. His passion for audio recording led him to pursue an audio engineer diploma at SAE Frankfurt. After completing his studies, the SAE Frankfurt offered him a lecturer position because of his expertise: Jürgen Schröder was responsible for a wide range of topics in the field of electroacoustics and digital audio, as well as responsible for the entire service technology of all studios.
After relocating due to family reasons, Jürgen was offered a position as test and tech editor for the Hi-Fi magazine "stereoplay" by Motorpresse Stuttgart, marking the beginning of his journalistic career. This led him, among other things, to the magazine "video", where, as head of the technology department, he dealt intensively with the topic of multi-channel sound systems.
Since 2009, Jürgen has been working as a freelance journalist and has written numerous product tests and technical articles for various Hi-Fi and music magazines. He has also been responsible for mastering many audiophile compilation CDs for Hi-Fi magazines.Together with 301 Studio Manager Ulli Schiller, Jürgen conducted several workshops at the HighEnd trade fairs 2012 and 2013 in Munich for "stereoplay," which received great audience response. One of Jürgen's current work focus’ is on the online HiFi and prosumer magazine, where he writes product tests and also oversees electroacoustic measurement technology. He also develops objective hearing test methods based on auralization.

Ulli Schiller

Ulli Schiller, born in 1956 in Minden, a city in the East Westphalia region of Germany, started playing flute, trombone, and church organ during his elementary school years. He soon discovered his love for acoustic and electric guitars and started performing with various local bands.
Schiller began his career at the Melitta factory, where he was trained as an electrical installation engineer and later as an energy systems electronics technician. After completing his Abitur (high school diploma) through an alternative education program, he studied electrical engineering with a specialization in telecommunications and information processing for five years. However, he found his true calling in the fusion of music and technology when he discovered the recording studio during his first semester in 1980. He began working as a runner and sound engineer at the PRISON STUDIO in Verl, where he spent eight years working with various artists and clients behind English mixing desks.
In the late 1980s, he founded the company KEMSONIC AUDIO MESS-SYSTEME GmbH in Bielefeld with a technician from a regional music store. The company developed, manufactured, and sold hardware and software for conducting electroacoustics and room acoustics measurements (RT, TSP, THD, QC, etc.).Starting in 1990, he taught electrical engineering, studio technology, room acoustics, session procedures, music production, and speaker design at the School of Audio Engineering (SAE) in Frankfurt. He became the head of the Frankfurt branch in 1992 and held the position until 2010. He then worked as a senior project manager for the German SAE headquarters in Munich until April 2015.
After 25 years at the SAE institute, Schiller changed employers and found new opportunities and challenges at Abbey Road Institute, an “education initiative” of the renowned Abbey Road Studios in London and the Universal Music Group. With over 30 years of teaching experience, he now works as a sound designer in music production and manages the Studios 301 Germany in Frankfurt. His motto is "MUSIC IS MY ENGINE," and he jokes, "I've slept more under Neve and SSL mixing desks in my life than in my own bed!" In addition, he still passionately plays and sings with the charity band GROOVING DOCTORS CHALLENGE.
