For stores with up to 8 speaker connections, a low impedance system is typically used. This system, usually with an impedance of 4 or 8 ohms, is ideal for a limited number of speakers and short cable distances. Because no transformers are needed, the low impedance system is simpler and more cost-effective. The amplifier sends the signal directly to the speakers, making it suitable for smaller spaces with fewer sound points.

For stores with more than 8 speaker connections, a 100V sound system is generally used. This system is specially designed for large installations with many speakers spread over a larger area. Thanks to transformers in the speakers, multiple speakers can be connected in parallel without impedance issues. This results in less signal loss and stable sound quality, even over long distances.

For stores seeking a sleek and reliable audio solution, brands like NEXT, Audac, and Biamp offer high-quality components for built-in installations.

NEXT provides compact, stylish in-wall and in-ceiling speakers with excellent sound performance—ideal for background music in commercial spaces.
Audac offers versatile amplifiers and mixers that integrate seamlessly with both 100V and low-impedance systems, including easy zone control and expansion options.
Biamp is known for its advanced audio platforms and DSP solutions, allowing centralized control over sound quality and functionality—even across multiple zones.

A large-scale sound system often uses a 100V system. This system is specifically designed to distribute sound over long distances with minimal signal loss. Each speaker has a built-in transformer, allowing multiple speakers to be easily connected in parallel without impedance issues. This makes the 100V system ideal for stores with many speakers spread across different areas.

Within this installation, sound can be divided into different zones within the store. This means different parts of the store can be controlled separately with their own volume settings and possibly different audio sources. For example, the warehouse can have different announcements or music than the sales floor.

The system is fully controlled by a powerful amplifier combined with a central mixer. This mixer ensures that all audio inputs such as music, microphones for announcements, and advertising messages can be centrally managed and mixed. This makes management simple and clear, even in complex installations.

Additionally, the system can integrate a public address (PA) system that allows live announcements via a microphone. There is also the option to schedule and automatically play pre-recorded advertising messages at preset times. This provides efficient and professional communication with customers and staff.

In a 100V system, the speakers have built-in transformers. This allows them to be easily connected in parallel without overloading the system. This makes it possible to place many speakers over long distances while maintaining sound quality. The system is ideal for stores with multiple zones and many speakers.

A 100V amplifier is the heart of a 100V speaker system. This amplifier converts the audio signal into a high-voltage output (100 volts), allowing long cable distances to be bridged without significant loss of sound quality. This enables multiple speakers with built-in transformers to be easily connected in parallel without overloading the system.

In a 100V paging system, you can easily make live announcements via a microphone, allowing you to communicate directly and personally with your audience. This is ideal for announcements, alerts, or special promotions.

It is also possible to play prerecorded advertisement messages or announcements automatically. This can be done via a playback device connected to the system, so you can broadcast consistent promotions during busy hours without needing someone present.

A small-scale sound system is ideal for stores with up to 8 speaker connections. This system operates with a low impedance (4 or 8 ohms), meaning the amplifier directly drives the speakers without the use of transformers. This makes the system simpler, more affordable, and easier to install than larger systems.

The lower costs result from using less equipment and simpler wiring. Additionally, this system is perfect for small to medium-sized stores that want to distribute clear, high-quality sound over a limited number of points.

Besides playing music, a small-scale installation also offers the possibility to play pre-recorded advertising messages. This can be automated via a media player or an integrated module.

Furthermore, it is possible to add a public address (PA) system, allowing live announcements by store personnel or via a microphone. This makes communication with customers more direct and efficient.

For a small store, a low impedance (4-8 ohm) audio system is often a good choice. The speakers connect directly to a standard amplifier without the need for transformers. This provides a simple and cost-effective installation with clear and powerful sound, ideal for music and announcements within a limited space.

Since the distances in a small store are short, signal loss is minimal and sound quality remains high. The system is perfect for one or a few zones without complicated wiring.

In a low impedance system, the amplifier plays a vital role. It reliably and powerfully delivers the correct current and voltage to speakers with an impedance of 4 to 8 ohms. Thanks to the low impedance, the amplifier can operate efficiently and provide optimal sound quality without risk of overheating or damage. This ensures you enjoy clear, powerful sound perfectly suited to your space and needs.

In a low impedance (4–8 ohm) audio system, you can also easily make live announcements using a microphone, allowing you to communicate directly and personally with your audience. This is ideal for announcements, warnings, or special promotions in smaller spaces such as shops or offices.

Additionally, it is possible to automatically play prerecorded advertisements or messages. This is done via a playback device connected to the system, allowing you to broadcast consistent promotions during busy hours without needing anyone to be physically present.
