Is AC current fundamentally better as a working current when it comes to amplifying audio signal?
No. If anything, using an AC power supply makes it more difficult to have low noise.
The circuits that handle audio are all powered by DC. So any amplifier that has an AC power input has to convert this to DC internally. The AC cabling inside the amplifier ...

You don't connect a microphone directly to an amplifier, you would normally connect it to a sound board to be able to adjust the eq and volume prior to going to an amp. The sound board includes a component called a pre-amp which boosts the signal from the level coming off the microphone to the level needed for the amplifier.
A mic signal is at a level ...

The type of current is actually completely irrelevant as all transmitted power is AC. Unless you are driving your amplifier from batteries, everything has to be converted at some point to DC.
The end result all boils down to the amount of power you need to draw from the supply in order to amplify the audio to the level you require.
The main reason why AC ...

If you want to do more percussive in your acoustic guitar, I remember that Fishman has developed their onboard-preamp, which I use. It's a preamp that combine undersaddle piezo with built-in mic beneath the preamp. Named "Classica Blend" or "Presys Blend".
Or if you prefer microphone, you can use Eric Clapton style. While playing acoustic guitar with both ...

Indeed it's easy to generate very loud noises with a speaker system whose power is only a fraction of what's actually used in PA or HiFi systems. What's not so easy is to get any sound you want to that level, without severely distorting it.
Perhaps most relevantly for music: bass frequencies need way more power to be perceived as loud as a 1 kHz signal. And ...

Those are powered speakers, at least they appear to be from a quick glance at the eBay page. Therefore, they have their own amplifier; you should be able to connect them directly to your microphone receiver.
BTW, some terminology: the jack/plug that you are calling 1/2" is known as a 1/8" or 3.5 mm plug (the diameter, not the length, is used to ...

First off… pros don't just decide they want to turn their amp up halfway through a gig. That's what sound crews are for; there's one guy whose job it is to make sure everyone on stage can hear themselves clearly.
That aside, at a large gig it wouldn't make the slightest difference front of house. There's not really a great deal of the actual amp's volume ...

Probably, yes. "Headphone power" depends basically on two things, output voltage and headphone impedance (I discussed it in some detail here). Many devices don't bother providing a very great voltage, but for dedicated headphone amps it's pretty much expected that they can make any off-the-shelf headphones loud enough for all typical use cases.
Still, if ...

I bumped into this years ago when, as a kid, I though hey, the more speakers the better!! So I connected 3 or four sets of speakers in parallel to the little system. It would often 'click' off like you describe.
It boiled down the the ohm ratings of the amplifier and speakers being entirely mismatched.
Also, check to be sure there isn't a short in the ...

The best shape for high frequencies (and some high mid) is the horn. But a horn can actually take many shapes. For example, its walls can be parallel like a didgeridoo. In fact, most, if not all, wind instruments are effectively differently tuned versions of the horn.
The reason the exponential horn is often used in loudspeakers (and this is an ...

I usually find that SM57s accentuate distortion/tinniness when the mic is pointed at the center of the speaker cone. My preferred placement is 45 degrees off-axis, aimed between the outer edge of the cone and the outer edge of the speaker. Tends to give a fuller reflection of the "sound in the room"... I'm not sure that this would totally mitigate your ...

It is impossible to tell without the input impedance of the speakers, but generally speaking the answer to your question is yes - you can damage either the speakers or the amp.
Say your speakers are each 8 ohms. If you connect 3 in series, you'll be presenting 24 ohms to the amp (8 + 8 + 8). This means the speakers will easily 'suck' the power off the amp, ...

While your plan to spend most on the microphone may actually be a good idea (you'll be able to use that microphone also at venues with a proper PA), this is not benefitial for your portable mini-amp setup. Pretty much all professional microphones (even some models for 30$) have a reasonably linear response if compared to any speaker available for 200$, so no ...

Your best bet is to get an SM58 for a microphone, it's the standard workhorse vocals mic, very durable and can easily be obtained for under the $200 price point. You're likely a bit off on the mixer and amp category though.
The little tiny toy amps you are talking about are not really designed for amplification. If you are in a small venue, running at ...

Welcome Sound Design Stack Exchange. I'm not sure this is really the right forum for your question and you may get better responses elsewhere.
Nonetheless it sounds to me like a fault with the amps drive circuitry and there is unlikely to be a quick fix: It might be as simple as a dry joint, but equally it maybe as complex as a thermal condition. Anyway, ...

Integrated circuit power amplifiers reach a point of negligible incremental return quite low on the cost curve. From a reputable source you are not going to see a measurable improvement beyond $20. It's an extremely mature technology, about the oldest and most active of any electronic technology. Correlating the quality of a headphone amp with price is ...

I've always found a contact cleaner, such as plastic-safe DeoxIT, works wonders for these types of connections. I normally spritz some on the plug itself, then work the plug in and out of the port a few times, spritz again, remove excess, plug in and go.

It's generally expected that you do a little bit of research before asking questions here and that you only ask one question. In this case the manual for this device answers the question quite clearly.
The Amp Out provides a 1/4 inch mono output of
guitar processed with amp modeling and effects and optimized for
connecting to the input of a guitar ...

You are correct in assuming that the speakers can only withstand the peak power for very short periods of time.
The VP2520 is a 4 Ω speaker. Looking at the technical specs of the amp, it seems the continous power per channel for a 4 Ω load is only 500 W (rms). The peak power is 750 W per channel. In other words, the VP2520 appears to be a perfect match for ...

You are probably trying to connect passive speakers to line out level outputs, therefore the low acoustic level.
What you need is a four channels power amplifier with 4 ohms speakers outputs.

This is most likely an issue related to microphone cable, connectors or wireless receiver. Try the following to determine the source of the error:
Test amplifier
Connect amp and speakers only - NO input cables connected at all, and turn it on with the volume a bit up.
Try gently shaking/pushing the power cable.
Try gently pushing the main volume fader ...

"Music" power is a rating that has its closest analogs in "RMS" power or "continuous" power handling. That means it is a long-term rating based on the speaker's capability to dissipate heat that is the byproduct of the conversion of electrical power to acoustic power. This rating means that you should be able to feed this speaker up to about 120 Watts of a ...

Well, it's like a game of Blackjack: to know the answer for sure, you'd have to bust your speakers.
If you have any amplifier at home or that you can borrow for a while, connect the speakers, put some music on WITH VOLUME SET A ZERO, and VERY CAREFULLY, turn up the volume litlle by little to see (actually to hear) how the speakers behave. Unless the amp is ...

Strictly speaking a "DAC" is a "Digital to Analogue Converter" which is a specific and critical component of the audio processing chain that connects a digital audio processing system with your hearing.
However, it is also used to describe a hardware device that works as an "external audio device" specifically for replaying higher quality audio than can be ...

To be honest, this is asking for trouble. I strongly recommend you purchase and use a DI box to isolate the amplifier from the computer. You are likely to experience hum and the DI will help to isolate. As @hobbes mentioned, under no circumstances connect the speaker outputs to the computer unless you need to buy a new computer.
The only connection that ...

Audio engineering uses decibels, because they are closer to how the human hearing perceives loudness: a double energy level is not twice as loud. A linear scale would require either a very large fader or be fiddly to tune towards the lower end.
If you're tuning your EQ by the numbers, you're doing it wrong. Use your ears! ;-)

First a short historical notice.
In the old days, professional headphones often where 600 Ohm, sometimes 250 Ohm. The IEC standard from 1996 recommended an output impedance of 120 Ohms for the headphone amp. This worked perfectly as the supply voltage in the headphone amplifier often was 20V or more. The value of 200 Ohms output impedance on the HX3 worked ...

First off, notice another label on the back of the amp: "Jacks paralleled". This means that both of the output jacks carry the same signal; there are two of them for the sole purpose of allowing you to plug in two cabinets without needing a splitter, or having a "daisy-chain" jack on the cabinets. This is a single-channel amp, as most guitar amplifiers are; ...
