[PC Speakers] Even seen a parallel port used to connect speaker toamp?
This is so damn weird that I just had to ask if anyone else has seen
this before. I was just looking at the user manual for a 5.1 PC speaker system that I was thinking about bidding on, and I noticed that while 4 of the speakers connect to the amp with typical audio plugs, the right-front speaker connects to the amp with a damn parallel plug! http://insigniaproducts.com/cms/docu...20EN_SP_FR.pdf (page 8) Why the hell would anyone ever do such a thing? |

If you look closer at the manual, you will see that the right front speaker has the controls for fader, master volume, and on-off. Still, my standard advice Insignia brand: avoid if possible. The worst sort of Chinese junk. Mark Z. |

Still, my standard advice Insignia brand: avoid if possible. The worst sort of Chinese junk. I've never owned an Insignia product before. The speakers did look a bit puny, but I was mainly interested in the 5.1 amp. |

That's not a parallel plug (DB 25), it is a 9 pin plug (AKA DB-9) of a standard variety that has been used for any number of different things over the past several decades. The basic design dates back at least as far as the Korean war if memory serves. It used to be used on only highly expensive, highest tech equipment but it has long been commoditized so it is now used on even very inexpensive, low tech equipment. In the realm of PCs, historical applications for exactly this plug (DB-9) have included serial communcations ports and EGA monitor ports. The tooling for making and installing this plug has been bought and paid off for a long time so it is inexpensive to tool and produce. The patents ran out decades ago. There are probably one or more production facilities for installing it in production quantities in most major cities in the world because it is so widely accepted. The DB family of connectors has a good reputation for durability when used with reasonable care. It is designed for, and well known to be effective at handling a wide range of voltage and power levels that includes this specific application. Why do such a thing? Why not? If a designer has a 9 wire analog interface, why not use a well-known, widely available realtively inexpensive connector that has a reasonably good reputation for reliability? |

No, the connector doesn't make replacing the speaker inconvenient, rather the multiple unique functions that speaker provides (controls for fader, master volume, and on-off) makes replacing that speaker impossible, except from the manufacturer. Yeah, impossible; it's not like I could actually cut a hole in the speaker box, run the speaker wires to another speaker, and effectively "replace" the old speaker, while still using it's build in controls. Like I said, inconvenient. The connector is irrelevant other than the fact that it makes connecting the necessarily unique replacement easier. So a serial cable with 2 screws is "easier"? Easier than what? The other speaker plugs that simply push in? You're sounding a bit trollish, dude. |

Those regulars who actually know of Dick will find that comment as amusing as I do I'm sure :-) As Dick correctly states, the connector is the least of your worries, although his use of the term "impossible" is obviously not true. Since these speakers are likely to be total crap, simply replacing any drive unit with anything that fits, and leaving all the unique features alone, will probably not degrade their performance at all, and should be easy enough for anyone who can use a screwdriver and soldering iron. And the use of a common DB9 connector will be of NO concern for anyone who can! MrT. |

Yeah, impossible; it's not like I could actually cut a hole in the speaker box, run the speaker wires to another speaker, and effectively "replace" the old speaker, while still using it's build in controls. Like I said, inconvenient. Let's all remember what this guy considers 'inconvenient'. The connector is irrelevant other than the fact that it makes connecting the necessarily unique replacement easier. So a serial cable with 2 screws is "easier"? Easier than what? The other speaker plugs that simply push in? So, let's make sure we all got this right. You're saying that when it comes time to replace this speaker, it's easier to unscrew two screws, unplug a cable, and, as you say, "cut a hole in the speaker box, run the speaker wires to another speaker," presumably cutting and stripping wires, soldering on connectors, to, as you say: "effectively 'replace' the old speaker" than it is to plug a new connector in and tighten two screws? No, replacing the old "puny" speaker (as I have previously referenced it) with the same puny speaker is not an option. Therefore, the options are to replace the speaker, or to not replace the speaker. You're sounding a bit trollish, dude. Thank you for your relevant, well reasoned technically informed comment. Clearly, people such as yourself have made enigneering and technical contributions if such significance as to advance the Internet to where it is today. Let me guess: what do we all think the chances are that this guy actually went out and bought these unmitigated pieces crap, and now wants the rest of the world to make him feel good and forget the fact that he screwed up? I did not buy them, nor did I ever place a bid on them, since I read the manual first, and realized that this was a product that I did not want. Or what about the possibility that he might actually realize that a DB9 is NOT a "damn parallel plug" as he first claimed and that, in fact, it's not at all uncommon for even high-end audio interfaces to use DB9s for multiple analog channel interfacing? I looked like a serial plug from the picture, but I specifically referred to it as a "parallel" since that's exactly what the manual calls it. As for how common it's use is, that *was* the very nature of my OP. Condisering how needlessly hateful you're being, you're obviously a troll, so I'm not going to bother reading the rest of your hollow post. *plonk* |

So *you're* post was pointless then, perhaps even a troll? so I'm not going to bother reading the rest of your hollow post. *plonk* Dick will be sooo heartbroken! :-) :-) MrT. |

My original idea was to simply get the amp and use it with my existing speakers, as my current amp only has a 4 channel output, and the 5 channels of the Insignia amp would have been nice if I could have grabbed it for cheap. I did not buy them, nor did I ever place a bid on them, since I read the manual first, and realized that this was a product that I did not want. So *you're* post was pointless then, perhaps even a troll? The point of my original post was to ask a question. |
