About Us

Take me directly to Range of services

Our adventure as Teknosign begins in 2011 but its history dates back far more distant. The two founders Claudio Furno and Riccardo Angeletti are known to each other for over 25 years. They have different experiences in the electronics business and decided to synchronize energies and put them into practice in the new 'Teknosign' brand.

Claudio furno is both a musician/music producer and audio electronics designer for over 30 years. During his career he always divided his work between his recording studio and the activity of freelance designer of professional audio gear. Over the years Claudio has achieved hundreds of musical productions in various genres such a synthetic pop, dance, house, techno, tribal and ambient published around the world. At the same time he has developed many innovative products that he also used and tested directly in his studio. He designed many personal audio products for big companies in the audio business as General Music, RCF, LEM, GEM, Davoli, MIZAR and others. Products range from preamplifiers, equalizers, compressors, feedback suppressors, audio matrix, power amplifiers, midi controllers, VCA automation systems up to mixer and PA Systems. In 1992 - in collaboration with General Music - he designed and built the first and real Total Recall digitally controlled analog mixer, led by Atari's software platform. At the time considered a revolution both in terms of digital control and in terms of sound quality: the Sound Engineer. The vast experience in the field of digitally controlled analog audio has led them to define Teknosign's true mission.

Riccardo Angeletti has always been involved in the field of electronic production. His father had a company of printed circuit boards in the 70's that was one of the largest nationwide. He entered in the company really young and then became the Director. Later in the 2000's he founded together with his wife another company of electronic assembly (Elettronica Service). In recent years, in addition to making third parts assembly, the company is looking to produce something of its own: a line of professional audio gear.

Therefore, combining the industrial structure in the production of printed circuit boards of Riccardo's with the extensive experience in the field of analogue gear with digital control of Claudio they have come to define the true Teknosign mission.

Take me directly to Our products

Teknosign's mission is quite straightforward bringing top handcrafted audio gear quality to the industrial level. Our products reflect not only the passion we have for music but also that for detail.

We are Italians and we never forget it.

Research and development, design, prototyping, printed circuit board manufacturing, assembling (both traditional and with surface mounted technology) and testing (Optical & Laser) are all carried out in our 1700 m2 building. This handcrafting spirit developed on a bigger scale is what brings you the best analog sound you can imagine.

But we are also looking forward. Our mission is in fact to bring a pure analog sound - as pure as it was in its best years - into the reality of Today's recording studios. This is possible by providing machines that have an analog heart but can be digitally controlled. This means having both the benefits of an analog sound (Color, Warmth, Depth and Contour) and those of a Digital Audio Workstation (Automation, User-Friendliness, Storage, Editing, Recording, Total Recall, etc.)

It will simply be the best of both worlds.


Our products range is composed by Summing Amplifiers, Pre-Amps, Patchbays, Power Conditioners, Studio Displays and Public Address System.
