Bipolar electrolytic capacitors

Bipolar electrolytic capacitors are the AC-resistant special form of electrolytic capacitors and are therefore suitable for music signals. They do not have a fixed plus/minus polarity and can be used where the polarity of the applied voltage is reversed during operation. Typical applications include large capacities in µF in filters and loudspeaker crossovers, when film capacitors would be too large for the same capacity. Here too, the core benefit is: high capacity with a practicable size. They are used in a dedicated manner when space and capacity requirements make economic sense.

Tight Tolerances

Tight tolerances in capacitance, inductance, and resistance ensure that capacitors of one type are very close together in terms of their electrical properties. In crossovers, the left and right channels therefore work virtually identically: crossover frequencies, level ratios and phase positions match closely. This is the basis for stable, precise stereo imaging and reproducible results — in series production and also after service.

Tonal Effects

• precise, stable soundstage without drifting
• Coherent overall impression: left and right channels fuse into a single, seamless whole
• characteristic sound is reliably retained even after component replacement/repair
• More stable virtual center and clearer spatial layering

Polypropylene Dielectric

Polypropylene is a high-quality dielectric with a low loss factor, low dielectric absorption and high dielectric strength. These properties enable the storage and delivery of electrical energy with extremely low loss and reduce unwanted recharging effects (dielectric absorption), which can introduce subtle temporal blurring into the music signal. Polypropylene thus forms the electrical basis of many MCAP series and is crucial for neutral, distortion-free signal transmission — and therefore a good prerequisite for all further optimizations.
