What is switch mode?

In a switch mode power supply the incoming mains is filtered then rectified to generate a very high voltage dc (direct current) supply. This is usually about 300 to 350 Volts dc, which is far too high to operate audio circuitry directly, and is still connected directly to the incoming mains supply. Such a high voltage is very dangerous and is one reason why the Klimax case should never be opened by a customer or a non Linn Products employee.

This high voltage is chopped up by very fast semiconductor switches and applied to a small transformer which both transforms the voltage to the value needed by the electronic circuitry and provides a safety isolation barrier from the mains supply. The size of a transformer reduces as its operating frequency increases, so a transformer operating at say 60,000 cycles per second is far smaller than one operating at mains frequency of 50 or 60 cycles per second.

On the output of the transformer, very fast rectifiers, a small coil and small capacitors filter and convert the high frequency waveform back to dc, ready for the electronic circuitry to use. By controlling the timing of the switches the output voltage can be held constant or varied, as required, without the need for further inefficient voltage regulators. This processing all happens well above the range of human hearing which, in principal, should be good for audio circuitry.

500 Solo specifications

The Linn 500 Solo is a high-performance loudspeaker that exemplifies the brand's commitment to audio excellence and innovation. Building on the heritage of Linn's acclaimed speaker systems, the 500 Solo was designed to deliver an immersive sound experience for both music enthusiasts and casual listeners alike.

One of the standout features of the Linn 500 Solo is its active design, which utilizes a dedicated amplifier for each driver. This configuration eliminates the need for passive crossovers, allowing for greater precision in sound reproduction. By amplifying the signal directly at the speaker, the 500 Solo can provide a more accurate and dynamic range, showcasing the subtleties of the music without distortion.

The speaker is equipped with advanced driver technology, including a high-performance bass driver and a specially designed tweeter. The bass driver features a large, lightweight cone that delivers deep, controlled low frequencies, while the tweeter is engineered to reproduce high frequencies with clarity and detail. Together, these drivers create a well-balanced sound signature that is suitable for a wide variety of music genres.

To further enhance sound quality, the Linn 500 Solo incorporates cutting-edge digital signal processing (DSP). This technology allows for real-time adjustments to the audio signal, compensating for room acoustics and ensuring that listeners experience the best possible sound profile, regardless of their environment. The integration of DSP also allows for customizable sound settings, enabling users to tailor their audio experience to their preferences.

The build quality of the Linn 500 Solo is another hallmark of its design. Constructed with rigid cabinet materials, the speaker minimizes resonance and vibration, which can negatively impact sound quality. Additionally, its aesthetically pleasing design is available in various finishes, allowing it to blend seamlessly into any home decor.

Connectivity options are also a strong suit of the 500 Solo, featuring built-in streaming capabilities that support a range of digital audio sources. This functionality allows users to connect wirelessly to their music libraries and streaming services, providing convenience and versatility in audio playback.

In conclusion, the Linn 500 Solo is a remarkable loudspeaker that showcases the brand's dedication to sound quality and innovation. With its active speaker design, advanced driver technology, and customizable digital signal processing, the 500 Solo stands out as a premium choice for audio enthusiasts seeking an exceptional listening experience. Whether used in a dedicated home audio setup or as part of a larger music system, the 500 Solo offers unparalleled performance and style.
