what is the difference between high and low input on amp?

high and low input on an amp. ... 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.

The difference between inverting and non-inverting op-amps lies in their name itself! Inverting configuration of op-amp gives amplified output which is 180 degree phase shifted. A non-inverting op-amp gives an output whose phase is same as phase of input.

In car audio, 4-ohm speakers are the norm. That's because car audio systems run on 12 volts DC instead of a 120 volts AC. A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers.

Conclusion. The sound contribution of preamps is not so much in its frequency response but in the texture it imparts on the sound. However, a preamp shapes the sound to a much lesser degree than one would think. Usually, its sound character only becomes obvious at high gain settings or when you drive it into distortion ...

No, not all amplifiers sound the same. But in terms of an overall system, they should be the component that has the least single effect on the sound. As with most things, especially in the audio world, spending more increases quality, but only up to a point. ... At that price point, most amps are going to sound similar.

Difference between 1 ohm and 4 ohm The lower a speaker's impedance, the easier it is for an amp to supply power to it. So, technically speaking, the only difference between 1 ohm and 4 ohm is the amount of resistance a speaker's voice coil applies to the audio current supplied by the amplifier.

A mono amp (monaural) has one input and one output. ... A two channel amp is more often called a stereo amplifier. Typically used for traditional hi-fi systems that have just a left and a right channel (or headphones with left and right earpieces).

A high impedance microphone or guitar will usually output a greater signal (voltage) than a low impedance microphone. ... A low impedance microphone will lower the impedance of the entire line connected to it.

The reason for making high input impedance is that “The circuit can be driven by any source” to avoid any loading effect. This ensures maximum current is provided by source. The reason to ensure low output impedance is that “The circuit can drive any load”, even the load impedance is small in magnitude.

Volume is how loud the OUTPUT of the channel or amp is. It controls loudness, not tone. Gain is how loud the INPUT of the channel or amp is. It controls tone, not loudness.

Active pickups have a hotter (louder) output than passive pickups. There is less signal loss on the way to the bass amp. Active pickups tend to be bright, clear and snappy sounding. Active pickups use smaller magnets and pickup less external noise and interference.

1 ohms, and most of them are, a 2 ohm speaker will be able to suck twice as much power from the amp. but usually they are less efficient than higher impedance speakers, plus amplifiers usually have a minimum load impedance, and sometimes it is 4 ohms.

Op amps have two inputs and one output. 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 main differences between a bass amp and a guitar amp are the speaker size, the power output, the amp features, and the frequency range. ... Guitars use a higher frequency range compared to bass guitars, so guitar amps are designed to use smaller speakers (eg: 8-12 inch) and drive those speakers in different ways.

Using an attenuator is no harder on your amp than running it just as hard into the speakers, in fact it's a little easier on it, with a resistive load there is less flyback voltage to cause arcing in the transformer and at the tubes/sockets. That is, with a properly matched impedance.

Electric guitar amps amplify an electric guitar signal providing more gain (for distortion), volume, effects for diverse sounds whilst slightly coloring the tone. In contrast, acoustic amps are designed to amplify a 'clean' and 'transparent' signal with notably more 'headroom' optimal for the clean sound of acoustic.

A microphone input is typically a very low level signal, and is mono. A line in will be expecting a much higher input level, and will usually be stereo. The sound card should have an additional pre-amp stage for the mic to bring it up to line levels.
