GIGA CANCELING PLUS
ull concentration on high-frequency interference – up to the crucial gigahertz range.
Experience your favorite music in an entirely new way – with an extraordinary sense of naturalness that creates a remarkably convincing live-performance experience.
The soundstage unfolds with its full width and three-dimensional depth, while musicians and instruments are placed with tangible presence in space. Notes are allowed to decay naturally and unimpeded, preserving their authentic structure and expressive character.
Beautiful tonal colors emerge free from harshness or artificial coloration. Instruments and voices appear vividly three-dimensional, tangible, and precisely defined – delivering a breathtakingly realistic musical experience.
Connected directly to the speaker, the SPEAKER AMP PROTECTOR protects the speaker drivers as well as the sensitive components of the crossover network.
Its high-frequency protection supports the precise interaction of the individual drivers, thereby optimizing the speaker’s time-domain performance.
When connected at the amplifier, the SPEAKER AMP PROTECTOR effectively shields against internal interference fields generated within the amplifier itself and which will permeate through the speaker cables and into the loudspeakers.
The SPEAKER AMP PROTECTOR helps to preserve the true nature of sensitive audio signals and guarantees an unharmed signal path for uncompromised sound reproduction.
Sound-impairing electrical interference fields are a really decisive factor for the realised quality-level of music reproduction of your audio system. The negative effects of interference in the low frequency range, well into the gigahertz range, are often and more consistently present than you would possibly think. It is almost unbelievable how strongly such interference fields can affect even the highest quality HiFi setups. It is therefore most impressive to experience how much sound potential of your audio system lies dormant and then awakens to perform truly mesmerizing as soon as these interference fields are effectively eliminated.
Electrical interference fields have a significant impact on the function and performance of audio equipment. In modern installations, multiple sources of interference occur simultaneously: low-frequency disturbances from the power grid, as well as high-frequency interference generated by digital circuits, switching power supplies, wireless communication systems such as Wi-Fi or mobile networks, and neighboring devices.
These disturbances enter the audio components through both the power supply and the signal cables.
This results in audible effects such as increased background noise, fluctuating supply voltages, less precise clocking of sensitive circuits, and reduced interference immunity in analog signals.
Since audio devices derive their internal references directly from the power supply, the quality of the electrical environment has direct influence on the overall transmission performance. Reduced electromagnetic interference leads to more stable operation, lower interaction between signals, and improved operating conditions for sensitive circuit components.
This is precisely where SCHNERZINGER comes in, specifically reducing both external and internal interference fields. The objective is to minimize unwanted electromagnetic influences and thereby improve the operating conditions of the audio equipment. The resulting improvement in sound quality is the direct consequence of an overall optimized physical environment.
The SPEAKER AMP PROTECTOR processes interference frequencies at high speed and absorbs them effectively. Interference has no chance of impairing the signal quality.
It requires no capacitors, diodes, series or parallel filters – and no energized crystals either. This is because these compromised components absorb energy and release it again with a time delay. This results in electron braking and delay effects that noticeably impair the sound.
The SPEAKER AMP PROTECTOR eliminates the high radio frequencies from the environment that are harmful to the sound, but not the high-frequency part of the music signal. This allows the sound to unfold in its full splendor – for an impressive sound stage.
The combined use of SCHNERZINGER products creates an incomparably strong synergy.
No wonder, because in this combination all our leading technologies merge into a perfectly coordinated system.
The sonic result?
An unimpeded, absolutely interference-free current transport that redefines the limits of musical reproduction.
