preamp inverts polarity

Costco, when speakers are “out of phase” I.e., the + - wires are reversed on both speakers, the system is in the Reverse Absolute Polarity from whatever state it was in previously. Polarity is relative. That’s kind of the whole point. And in that sense, as on the test track on the XLO Test CD, “out of phase” is equivalent to Absolute Polarity. I suspect this is just a simple case of you following the wrong ...you know...🐑 🐑 🐑 |
kosst_amojan The transmission characteristics of air certainly don’t resemble electrically balanced operation.That doesn’t mean that air is a "single-ended medium," as you’ve claimed. Air is also not a fig newton. That doesn’t mean air is a lemon meringue pie. |
@ kosst_amojan - of course you’re correct (definitions of polarity vs. phase). By the time I noticed the typo, the 30 minute edit window had expired. It never pays to post before going to bed ;-) @ geoffkait absolutely (with respect to how media is recorded). This might be the biggest factor as to why so many folks don’t "hear" polarity reversals. They doubt their perception - as much because of inconsistencies in recordings as any other factor. Cheers, Thom @ Galibier |
I’ve read this whole thread and will never get that time back. Invert connections on both speakers then listen. If it sounds better then before, leave it. If your cables are built differently for negative and positive, try it anyway. If your preamp has a polarity switch, use that instead. Some recordings were recorded or mastered with inverted polarity, so the “right” polarity may vary. |
this whole thread has gone off base and no one has answered my question. my preamp requires me to reverse cables at the speaker end, by design my speaker cables have designated cables for negative connection and positive cables. the positive and negative cables are of different compositions by manufacturer design. my question is if I follow the preamp directions I will be defeating the design of the speaker cables, so which is it? |
this whole thread has gone off base and no one has answered my question.Your question was also answered by the post immediately proceeding the one quoted here. Here is that post again: Invert connections on both speakers then listen. If it sounds better then before, leave it. If your cables are built differently for negative and positive, try it anyway.You can see that inverting the speaker connections with every LP or CD is going to be a pain. So if you have a lot of recordings that are made with only two microphones, get a preamp with an inversion switch so you don't have to be constantly behind the amps making the switch. |

costco_emoji @geoffkait As usual, you’re pretty much wrong. Vacuums don’t exist anywhere in the known universe. >>>>What a knucklehead. I stated that a vacuum is defined by the number air molecules per unit volume. A perfect vacuum is defined as the absence of any molecules in a given volume. There are degrees of vacuums, that’s why vacuums can be measured and there are units of measurement. Obviously some vacuums are better than others. Why do you often give the impression one exists between your ears? |
How can anyone hear polarity reversal correctly unless the speakers are phase coherent to begin with? Many speakers have their tweeters and mid/woofers wired in reverse phase. That happens because of the nature of the crossovers they use. Only first order, or full range, single driver, speakers will be phase coherent. Never the less, the listener may prefer one polarity setting on their DAC by the way the correct polarity improves the bass... but the upper range will be diffuse when that happens unless the speakers are phase coherent |
" >>>>my preamp requires me to reverse cables at the speaker end, by design my speaker cables have designated cables for negative connection and positive cables. the positive and negative cables are of different compositions by manufacturer design.<<<<""""" An amplifier’s terminals are "push pull." They are marked red and black so you can get both channels hooked up the same consistently. When a preamp reverses polarity? Now the positive terminal will be pulling when it normally would be pushing. So, who ever designed that cable with its unique negative run? It is a marketing genius for the uninformed. For, at any moment while playing music the direction of the current in the speaker cables can change directions! Its what controls the speaker movement... There is no one direction for each leg of the speaker wires. They share in moving current back and forth. One second a terminal can be pushing. The next split second on the same terminal the direction can be reversed.... There can not be a dedicated cable material for the side that gets called the negative side. For it shares in pushing and pulling the signal. |
