I think lower chassis voltage does not give better sound in all audio systems.I do not why but Some audio systems have better sound with higher chassis voltage . I lost my sound for more than six month only for adjusting ac polarity for lower chassis...

[quote user="clarkjohnsen"] Folks, in case you care to learn the truth of the matter, AC Polarity is the subject of Chapter 7.5, pages 63-66. Its connection to acoustic polarity is established there too. That Romy should so boldly assert otherwise, l...

[quote user="clarkjohnsen"] Thanks for the lecture on material I've been closely acquainted with for thirty years. But please don't try to dodge the issue, viz., that you erroneously said AC plug polarity has "nothing to do with The Wood Effect". The...

"You mistakably took roundness but it was nothing but confidence and luck of my interest to contaminate the thread with another introduction of acoustic absolute phase." Folks, I invite you to look at the record. I introduced AC plug polarity and whe...

"Meanwhile, I suppose we mostly tend to think of "phase" as a 180 proposition, +/-, either/or." Not I, sir! Phase is a matter of degrees. Polarity is a total flip, which is why it's a far better word for the two conditions under discussion.So let's p...

I think I figured it out. Capacitor polarity. I reversed the polarity (leads are black and red) and sound changed. Now it sounds closer to what I am looking for, with better transients. Not as good as the digital crossover in the transient department...

After reading this thread I can't help but wonder whether y'all are familiar with the concept of AC polarity. The topic has been addressed in numerous locations (most thoroughly in Bound for Sound), but perhaps not recently. In short, which way the p...

This may have been mentioned already. . . if so, it escaped me. But here's the thing: Each component has its own AC chassis leakage characteristic. This can be measured, and lining every component up by the same polarity produces less noise & hum...

Thanks Romy. On the AC polarity do you mean playing with the player/amp polarity or with the PP one? I always try to have all devices to be in phase.Denis...

For those seeking convenience or the plain lazy there's an interesting and very affordable gadget from Van den Hul:
POLARITY CHECKERWorks without a battery, thus is always ready for use !
Its liquid crystal display safely senses and indicates the v...

There are some information here and here, particularly among those who knows, how the misbalance of the power polarity between the components of your systems can screw sound. Certainly the auditable benefits are very substantial and anyone who power ...

Srajan La Pergola just announced that Danish company “FMJ Audio” began to make an acoustic phase tester. An acoustic phase tester is absolutely mandatory thing for anyone who uses horns. If a person use horns and has no ways to objectively recognize ...

Actually, the above mentioned “Phase-it” devise has on-board “generator” that sends out the pulses and they it looks like the pulses of the high voltage, the speaker level pulses. I do not find it convenient and I do not know if the “Phase-it” devise...

This trick of disconnecting all the grounds works, depending. . . I am not a happy or unhappy, as the case may be, PP owner, but I know this to be the case anyway.Now, is everyone aware that which way the plug is mounted in the socket make a differen...

Checking if you playback can discriminate absolute polarity is very simple and very effective way to find out if you acoustic system is not fundamentally faulty. Flip the polarity and monitor the result. If you did not experience dramatic changes at ...

If C10 is connected backwards there could well be a large leakage current through it. It may also have been damaged if this is the case, requiring its replacement....

And this capacitor is connected as shown in the photo. its minus goes to mass, its plus goes via R21 to the B + tap in the OTP transformer. I waited for the resistance to stabilize, which started at 2 million ohms and stopped at 42 million ohms ...

[quote user="el`Ol"]Romy, What happens when you use the injection channel with inverted polarity?[/quote] Unsuccessful. My Injection Channel (Tannoy 10” Red) is too with bandwidth and even at minus 10db is “talks” with HF channel of Macondo, which do...
