Frequently Asked Questions

What is an amplifier?

An amplifier is a device that changes the size of an electrical signal. The purpose of an amplifier is to receive a small electrical signal and amplify it.

In the case of a pre-amplifier, this amplification needs to be enough for power amplifiers. Power amplifiers need even more intense amplification in order to provide sound that is good enough to fill entire rooms with loud tunes. Amplifiers are often mysterious-looking boxes but inside they really just take input signals from our source (a mobile phone or turntable) and amplify them to create amplified outputs for us.

What is an integrated amplifier?

An integrated amplifier is a preamplifier and power amp built into one piece of equipment, which helps to control distortion. This means that you can use it for both small stereo systems or large surround sound setups while eliminating the need for extra gear in your audio rig.

These amplifiers provide the pre-amplification and power amplification necessary when using headphones or more than one speaker as sound output devices. They are also a great option if you need equipment that is self-contained because they usually include all input switching components and equalization circuitry needed for this purpose.

What is Signal-to-Noise Ratio for an amp?

A signal-to-noise ratio is a measurement that takes the level of noise power and compares it to the amount of useful information or “signal” among other things. The higher this number goes, usually means better specifications because there are more signals with less unwanted data in between them.

You want a good s/n ratio of 80 decibels or greater in order for your amplifier to function properly and give off a high-quality sound.

What is a preamplifier vs amplifier?

A preamp boosts the strength of a signal to line level so that it can be sent through speakers. An amplifier, on the other hand, amplifies low-level sounds in order for them to come out loud enough.

What is a low-noise amplifier?

A Low-Noise Amplifier (LNA) is a device that amplifies signals of very low strength, making them clearly audible. LNAs are one the most important circuit components present in radio and other signal receivers as they prevent noise from being amplified along with the desired frequencies.
