But those are faults in the installation, failure to follow procedures. That is different from faults in the DESIGN of the connectors! Jack plugs fail even when they are installed correctly. Everone knows bad contacts with jack plugs, and the procedure to recover good contact. With RCA Phono plugs, about the same thing. You will not have seen those issues with XLR or SpeakON. |

You should at least tape it thoroughly to avoid rotational forces reaching the solder joint, it it will fail again. BTDT! CH |

Nickel plate wears off and corrodes, plastic frame jack sockets break apart if cables get yanked hard. But XLR and Speakon type connections are not immune - I often see ones that do not work any more. Cos there good ones and *bad* ones, famous brand examples being the former and cheap knock offs the latter. I have seen examples where near new Speakon style 4 pin plugs failed to connect to perfectly good sockets. Also, Speakons of all kinds will snap in half if the cable is yanked hard at right angles or is otherwise impacted. Plastic body XLR panel females are good only for so long - then become damaged, intermittent and hard to fix. You get what you pay for and connectors subjected to regular heavy use *need* to be the more expensive types. ...... Phil |

These incorporated ring terminals and threaded machine screws with lock washers, internally. You can make anything in a shoddy manner. Price rules. Largest source of failure in current product - even moulded assemblies, involves lousy strain relief and physical manhandling. RL |

Should a circuit breaker blow, you will know what is shared. Remove those shared items and start over. If both units happen to be on the same circuit, use only one (1) at a time. > Ideally any AC line should be (at least) a dedicated 20A circuit using (at least) 12-gauge wire. Then there would be no discussion. If this is a rental, I feel her pain. If this is owned, install the dedicated circuits as-needed. They will not go to waste. A 20A circuit max rather than a a 15A circuit max on a 240AC residential hook up. |
