Design By Mr. K writes: “Rotor Balanced Fire Bull” is not a hi-fi supplement!! You must understand the principle of impedance, and using the right tool will improve the effect. Improper use will only make things worse.
This product is specially designed to overcome the challenges of small dwellings in Hong Kong. Due to limited space, speakers often suffer from excessive or insufficient treble and bass. If your speakers have bi-wire input (Bi-Wire), you can utilize different output impedance to adjust the volume. The advantage is that it won’t affect the phase, with phase drift close to zero. Unlike an equalizer, adjusting this product won’t seriously impact the phase, ultimately affecting the audio positioning.
This product plays a similar role to the output fire bull in the front of the gallbladder and the back of the stone. It promotes smoothness and reduces digital artifacts. The amplifier will also exhibit the characteristics of a tube amplifier. It’s truly a savior for CLASS D amplifiers.
As we all know, the design of transistor amplifiers is based on 8-ohm output.
However, modern speakers often have 6 or 4 ohms impedance, leading to mismatch issues, and the speakers become difficult to drive. For example, a 100W pure Class A amplifier, when driving a 4-ohm speaker, becomes Class AB if it exceeds 30W. By using this product, it remains 100W at 4 ohms and stays in Class A, as it’s an autotransformer that can double the output current, producing outstanding results.
This product is also specially designed for LS 3/5A speakers. The design of the transistor amplifier is based on an 8-ohm output, and some tube amplifiers do not have a 16-ohm output. Therefore, this product is designed with 11-ohm and 15-ohm outputs, ensuring a complete impedance match, allowing the amplifier to drive the speakers effectively.”
