what is the difference between a 1 and 2 channel amp?

A 2-channel amplifier will be the practical solution when you only need to power a single pair of speakers. But if you like rear-fill sound in your car and want to retain front-to-rear fade control, get a 4-channel amp — one channel for each speaker.

The high and low inputs are part of the amp's design which allows you to use either active pickups or passive. While either input will work, high is for passive, and the low input is for active.

Anyway. The only Orange amp that is Class A is the AD5. Class A doesn't mean that it's better, it's just a different way of operation. They do sound different, but it's quite marginal.

An amplifier is used to increase the strength of an electric signal whereas a rectifier allow current to pass in only one direction and is used to produce DC. from AC.

Amplification means voltage ratio V2 / V1 = Vout / Vin, and voltage gain in dB = 20 × log (V2 / V1). V1 = 1 Volt.

Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass. On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass. Thus, make your choice depending on the kind of bass you want.

Subwoofer support The first digit of the 2.2 nomenclature represents the number of speakers – or main audio channels – involved, whereas the second digit provides an indication of whether or not the sound system contains a subwoofer or supports low-frequency effect channels.

In class AB operation—which is typical for many amps with two power tubes—each tube handles more than half, but not the full wave. Any amp with a single power tube (aka “single-ended” amps) will always be class A—that single tube must handle the entire wave.

The difference between a bass amp and a guitar amp is in the power output and the size of the speaker. ... The bass amp also requires a bigger speaker, so it could reflect the sound of the bass guitar effectively. On the other hand, the guitar amp can do with a smaller speaker.

riffmeister Member. the first volume controls the amount of signal going through the preamp section. the second volume (master volume) controls the amount of signal going through the power amp section.

A subwoofer with a lower electrical resistance produces a louder sound than one with a high electrical resistance, which means that 2ohm subwoofers are louder than 4ohm ones. Although louder, 2 ohm subwoofers are also more likely to produce a poorer quality of sound due to its' power consumption.

The mini Twin is a single- channel amp, with controls for volume gain and tone - the fourth knob is the on/off switch. The Mini Twin is good-looking, but compared with some of the competition it's somewhat short on features; all you get is a headphones jack and a belt clip, which isn't so useful for non-belt wearers.

What is the current flow through R1, R2, and R3? = 1 Amp.

Both BIAS Amp 2 and FX plugins are similar, and just at a glance, they look the same. The main difference between BIAS Amp and FX is: (Amp) has more amp features but no effects. (FX) has limited amp features with a hefty array of stomp box and rack mount effects.

It does make a difference depending on amp & speakers whether its better or not is open to debate. At the low end a better quality speaker cable with decent jumper bars is more worthwhile. The whole thing is system dependent as some speakers/cable/amp combos dont like it and some do. Bi amping is always worth it.

Instrumentation amps usually have three inputs (ref is an input) and a gain control facility, and one output. Differential amps usually have two outputs and usually two inputs. None are directly electrically interchangeable and this is a performance and usually functional thing.

The amp is essentially the machine that takes the signal input, it's what translates the sound your instrument creates. The pa is the speaker, it takes the signal from the AMP and replays it as the sound that you actually hear.
