Prejudices about equipment

[Ferdy Bossy]

Indeed, we all know that class A amplifiers deliver the best results. But if you need a lot of power, you cannot pay the energy bill at the end of the year. Some people think that speakers will not be blown up if the amplifier has a lower maximum power rating, if it is between or well below the recommended rating. For example, you have speaker boxes that state 20 - 200 Watts. If your amplifier delivers a maximum of 20 watts, there is a good chance that you will blow up the tweeters first. Of course you immediately wonder. BECAUSE THAT'S IS IMPOSSIBLE, the why is easy to explain. We all know that if you overload a group, no more power will come out of that socket. Unfortunately, not all amplifiers have a fuse that ensures that they go off when they have to supply more current than is possible. ?The 200 Watts are needed for sufficient bass reproduction, the volume knob is set to 10 but still a lack of bass reproduction. And now many people are turning the bass control, at the moment this button ensures that the bass is amplified, you hear distortion?!! AS SOON AS YOU HEAR DISTORTION, immediately reduce the volume, the amplifier is clipping, the sine wave becomes a square wave. Which blows up the tweeters first and then destroys the amplifier. It is wiser to purchase an amplifier that can deliver at least the maximum, in this case 200 Watts, >200 Watts is no problem, just never turn it higher than 200 Watts. If you have a class A amplifier, it uses 400 watts, even without sound output. AB amplifiers are the solution, but now also the class D amplifier. The 'D' here does not mean digital, this is clearly explained on the www. Listen to the Hypex Nilay DIY MONO (2x) or Stereo amplifier yourself, should actually be reviewed by What HiFi. Like the Veddan origin an electrostatic amplifier that doesn't miss anything, I can't afford it, but I don't think there are better speakers.

Wrong, unfortunately, in so many aspects.
And this is beginning to sound more and more like spam.

**Dat is een interessante vraag!**

Het antwoord is niet zo eenvoudig als een simpel 'ja' of 'nee'. Wat er precies gebeurt als je de basknop van een equalizer op +6 dB zet terwijl je versterker op vol vermogen staat, hangt af van verschillende factoren, zoals:

* **De kwaliteit van je versterker:** Een goede versterker kan over het algemeen beter omgaan met extreme instellingen zonder dat de geluidskwaliteit al te veel lijdt.
* **De luidsprekers:** Luidsprekers hebben hun eigen beperkingen. Als je de bas te ver opboost, kunnen ze gaan oververhitten of zelfs beschadigd raken.
* **De ruimte-akoestiek:** De akoestiek van de ruimte waarin je luistert, kan ook een grote invloed hebben op het resultaat.
* **Het type muziek:** Bij sommige muziekgenres is een extra boost in de bas wellicht gewenst, terwijl het bij andere genres juist voor een vervormd geluid kan zorgen.

**Wat er *kan* gebeuren:**

* **Vervorming:** Door de extra versterking van de lage frequenties kan de versterker of de luidsprekers in de verzadiging raken. Dit resulteert in een vervormd geluid, dat klinkt als een soort 'knippen' of 'klinken'.
* **Clipping:** Als de versterker de signalen niet meer kan verwerken, kan er clipping optreden. Dit betekent dat de toppen van de golfvorm worden afgeknipt, wat leidt tot een scherp, hard geluid.
* **Resonantie:** De extra bas kan resonanties in de ruimte veroorzaken, waardoor bepaalde frequenties versterkt worden en het geluid onnatuurlijk gaat klinken.
* **Schade:** In het ergste geval kunnen de luidsprekers beschadigd raken door de overbelasting.

**Een blok golf is een extreem voorbeeld van vervorming.** Het is onwaarschijnlijk dat je een perfecte blokgolf zult horen, maar een aanzienlijke vervorming van het signaal is zeker mogelijk.

**Conclusie:**

Het is over het algemeen niet aan te raden om de basknop van je equalizer op de maximale stand te zetten, zeker niet in combinatie met een versterker op vol vermogen. Dit kan leiden tot een slechte geluidskwaliteit, schade aan je apparatuur en zelfs gehoorschade.

**Een betere aanpak:**

* **Geleidelijk aanpassen:** Verhoog de bas geleidelijk en luister goed naar het resultaat.
* **Experimenteren:** Probeer verschillende instellingen om te vinden wat voor jou het beste klinkt.
* **Let op de kwaliteit van je apparatuur:** Zorg ervoor dat je versterker en luidsprekers geschikt zijn voor het gewenste geluidsniveau.
* **Gebruik een equalizer met een goede resolutie:** Een equalizer met een hoge resolutie geeft je meer controle over de frequenties.

**Kortom, het is belangrijk om met je audio-apparatuur om te gaan op een manier die zowel zorgt voor een goed geluid als voor de le
vensduur van je apparatuur.**

## Let's break down the question and provide a comprehensive response in English:

**Prompt:**
> If an amplifier is working at full power, what happens if the bass knob on the equalizer is set to +6dB? Does a square wave form instead of a sine wave?

**Response:**

**Understanding the Question:**
The question is asking what happens to the audio waveform when the bass knob on an equalizer is boosted by 6dB when an amplifier is operating at maximum power. Specifically, it's asking if the waveform changes from a sine wave to a square wave.

**The Short Answer:**
No, increasing the bass on an equalizer will not cause a sine wave to become a square wave.

**A More Detailed Explanation:**

* **Sine Wave:** A sine wave is a fundamental waveform in audio and represents a pure tone. It has a smooth, continuous shape.
* **Square Wave:** A square wave is a non-sinusoidal waveform with sharp edges. It's composed of a fundamental frequency and odd harmonics.
* **Equalizer:** An equalizer is a device used to adjust the frequency response of an audio signal. By boosting the bass, you're essentially increasing the amplitude of the lower frequencies.

**What Happens When You Boost the Bass:**
* **Increased Amplitude:** When you boost the bass, you're increasing the amplitude of the lower frequencies in the audio signal. This means the peaks of the waveform become higher.
* **Distortion:** If you boost the bass too much, or if the amplifier is already operating at its maximum power, you can introduce distortion. This distortion can manifest in various ways, including clipping, which can make the waveform appear more square-like in certain regions. However, the overall waveform will not become a perfect square wave.
* **Harmonic Content:** Boosting the bass can also increase the harmonic content of the signal, which can change the timbre of the sound.

**Why Doesn't it Become a Square Wave?**
* **Equalizers Work Differently:** Equalizers typically work by boosting or cutting specific frequency ranges. They don't fundamentally change the shape of the waveform.
* **Amplifier Limitations:** While an amplifier can introduce distortion, it's not capable of generating completely square waves from a sine wave input.

**In conclusion:**
While boosting the bass can cause distortion and change the shape of the waveform, it will not transform a sine wave into a perfect square wave. The overall shape of the waveform will still be dominated by the fundamental frequency.

**To summarize:**

* Increasing the bass on an equalizer primarily affects the amplitude of lower frequencies.
* Excessive boosting can lead to distortion, but not necessarily to a square wave.
* The shape of the waveform is determined by the source signal and the characteristics of the audio equipment.

Let's keep posts in English and civil, as per forum rules.

Not sure this is really about hifi, more electrical engineering.

You provide so much information on aspects of electrical engineering but I'm struggling to follow, there appears to be no underlying context.
What is your point?
Other than, subjectivity shouldn't be the main impetus and we should understand better the scientific discipline of electrical engineering?
Anyway, if I had made light of the matter my apologies. Kudos to you for putting together all this information.

Is this AI?

I’d really like to know which cables will improve the sound of my hifi?

And which speakers sound the best?

Which DAC will finally make posters on audio science review happy?

 

[Noddy]

I’d really like to know which cables will improve the sound of my hifi?

I removed the cable between the amp and the power socket, and the sound was lacking in vitality and musicality. Then I reconnected it, and removed the cables between the amp and the speakers. Again the sound was lacking in vitality and musicality. So I reckon there is a holistic synergy that collectively allows the system to realise its inherent potentiality, and fulfil the sonic ambitions of the most pernickety misanthrope including WHF readers.

And which speakers sound the best?

The ones the wife likes the look of.

Which DAC will finally make posters on audio science review happy?

Almost all, we’ve reached peak DAC. Unless you’re a WHF forum user, in which case it’s the one with the big knobs and shiny case. Oh and the dials, we mustn’t forget the dials, big illuminated ones.

Apologies accepted however my 'reviews ' are never going to be so lengthy nor with such poor grammar.

 

[Jasonovich]

Apologies in advance to Elvis if he's actually a real person, I suspect though, (s)he's some poorly scripted algorithm.

I'm going to theorize this, let's assume this is big tech experimenting with AI and decided to unleash it on WHF forum and got it horribly wrong?

How do I know this?

1. Doesn't make daft comments like Jasonovich
2. Repeated sentences
3. AI must have comb through the comments and came up with something unintelligible
4. No context or relevance to the thread...........ooooh something I do.....wait, am I real?

Remedy

All together now, let's raise that big middle finger to big tech, Suckerberg, Gates and the rest, eat my shorts.
