Walk with us and help paving the way to
all new public address systems

About Us

Vision

We are a technology startup, founded in late 2023. We develop and distribute electronic components, firmware and SDKs that will be used by other companies in their public address systems (PA) to take them to a whole new level of price/performance and functionality.

For this we use our revolutionary new and patented approach.

We also partner with loudspeaker manufacturers who incorporate our technology to create a complete system for the end user.

Thomas Zwick, CEO

Thomas has a strong engineering and software background, has held various leadership positions in the semiconductor and electronics industries, and strives for innovation and progress.

Oliver Schlief, CFO

Oliver has an indispensable experience in commercial issues for our company through various management positions in technology companies and as controller of an investment company.

Mission

Provide a complete ecosystem as development, service and maintenance support for novel public address systems.

Where We Stand

Status

After a successful prototype phase, our techology is now in the development phase.
Subsequently, the market testing will start. Want to be part of it? Join the team.

Our Values

Status

We want to achieve a positive impact on society, safety, climate and the environment through our actions and dedicate ourselves exclusively to promising and sustainable technologies.

Our Technology

For over 150 years, public address systems (in 100 V technology) have been implemented in essentially the same way.

IT IS TIME FOR A CHANGE

PA

What is a PA system?

×

A fixed 100 V public address (or PA) system is an electronic system with microphones, amplifiers, loudspeakers and associated equipment. It increases the apparent volume (loudness) of a human voice, background musical, or any other acoustic sound source. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area.

Typical fixed installations include sports stadiums, public transportation infrastructure and vehicles, public buildings and industry facilities. A PA system may include multiple microphones or other sound sources, audio matrixes to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution.
