Este cumva vreo schema, un montaj, o piesa ceva pentru a proteja tweeterul la depasirea puterii lui sau pentru atunci cand incepe amplificatorul sa produca distorsiuni?
Daca puteti spune si cum functioneaza este nemaipomenit  |

La depasirea unui prag de distorsiuni nu stiu sa fie dar la depasirea unei puteri date exste si inca foarte simpla
| Citat: | | Low cost speaker protection.More specifications ensure accurate choice for better protection. Polyswitches will protect against electrical (current) overload and will protect speakers in most situations. They are not foolproof and will not protect against mechanical overload. Select the device based on its trip (power rating W), eg. if you need to protect a tweeter that will handle 10 watts RMS and its rated at 8 ohms you would select an RXE075 device. If in doubt, be conservative. Some experimentation may be necessary since music signals can vary a great deal. Simply connect in series with the speakers you wish to protect. See our Data section for more technical info. How they work. Polyswitch protectors are based on conductive polymers and act like resettable solid state circuit breakers. When the operating current of the protector is exceeded the interior of the device partially melts, which suddenly increases the volume which increases the resistance drastically. This in turn reduces the current. The device stays in this state while the current is maintained because its temperature is elevated. Once the current is removed, the device re- establishes itself almost immediately, so that the low resistance value is restored.Voltage ratings |
Cirteste ca eu nu stiu sa-ti traduc si apoi intreba-ma unde gasesti piesele astea

Oare nici Conex si nici Vitacom nu au polyswitch-uri?
Am vazut parca intr-o schema de filtru pusa pe-aici pe forum (de la Visaton parca) un polyswitch pus pe inalte.
Am inteles ca Doru se ocupa de reprezentarea Visaton aici.
Nici la el nu se gasesc oare aceste piese? |

Costa in jur de 50 mii bucata, se poate ca unele modele sa nu fie in stoc dar au alte tipuri BAUELEMENT-uri echivalente cu astea.
