A phono preamp and an amplifier are two different components in an audio system. A phono preamp is responsible for amplifying the weak signal from a turntable cartridge and applying the RIAA equalization curve. An amplifier is responsible for amplifying the signal from a preamp to a level that is compatible with speakers.
Phono preamp
A phono preamp is a necessary component for any vinyl playback system. Turntable cartridges produce a very weak signal, which needs to be amplified before it can be played through a speaker system. The phono preamp also applies the RIAA equalization curve to the signal. This is a standard recording curve that was developed by the Recording Industry Association of America in 1954. It is used to boost the bass frequencies and attenuate the treble frequencies on vinyl records. This is done to save space on the record and to reduce surface noise.
Amplifier
An amplifier is responsible for taking the signal from a preamp and amplifying it to a level that is compatible with speakers. Amplifiers typically have a number of inputs, so you can connect multiple sources to them, such as a turntable, CD player, and streaming device. Amplifiers also typically have a number of outputs, so you can connect multiple speakers to them.
Differences between a phono preamp and an amplifier
The main difference between a phono preamp and an amplifier is that a phono preamp is specifically designed for amplifying the signal from a turntable cartridge, while an amplifier is designed to amplify the signal from any line-level source.
Another difference is that phono preamps typically have a higher gain than amplifiers. This is because turntable cartridges produce a very weak signal. Amplifiers, on the other hand, typically have a lower gain, as they are amplifying a signal that has already been amplified by the preamp.
Finally, phono preamps typically have a different type of input than amplifiers. Phono preamps have a phono input, which is designed for the low-level signal from a turntable cartridge. Amplifiers have a line-level input, which is designed for the higher-level signal from a preamp.
Do you need both a phono preamp and an amplifier?
If you have a turntable, then you will need both a phono preamp and an amplifier. The phono preamp is necessary to amplify the weak signal from the turntable cartridge, and the amplifier is necessary to further amplify the signal to a level that is compatible with speakers.
If you do not have a turntable, then you do not need a phono preamp. However, you will still need an amplifier to power your speakers.
