The RIAA amplifier – the way to better sound
In order to be able to play a record at all and get the music out of the speakers, you must have a preamplifier which, in this context, is called an RIAA amplifier. The RIAA amplifier has two important functions: it amplifies the very weak signal coming from the turntable's pickup, and it corrects the frequency curve to recreate the original sound from the record's recording.
During the cutting of a record, it is necessary to lower the bass and raise the treble, as this helps prevent the pickup from jumping out of the groove and reduces noise and hiss in the audio recording. Unfortunately, this also means that the audio curve must be restored before it can be played back with optimal sound quality. This is where the RIAA amplifier comes into play - by correcting the frequency curve and amplifying the signal, you can get the balanced and natural sound that the turntable is known for.
MM-RIAA or MC-RIAA
Many amplifiers have a built-in RIAA, and such an input is typically called "phono". If you do not have a built-in RIAA in the amplifier, it can be purchased separately and connected to a regular line input on the amplifier, e.g. CD, AUX, TUNER.
An outstanding MM-RIAA can be acquired for approx. DKK 1000, whereas an MC-RIAA costs quite a bit more and works in the same way, apart from its even stronger amplification. This is because an MC pickup typically has a much weaker output signal to send into the RIAA part, and therefore the signal requires a stronger amplification.

RIAA Amplifier FAQ
Confused about what an RIAA amplifier is and why you need one? Here are some answers that should make it all a little more understandable.
What is an RIAA Amplifier?
An RIAA amplifier is a preamplifier used to play vinyl records. It has two important functions: to amplify the weak signal coming from the record's pickup and to correct the frequency curve of the signal, which has been changed in the cutting process in order to be stored on the record.
Why is an RIAA amplifier necessary?
The plates are cut in such a way that the bass is lowered and the treble is raised, so that the pickup does not jump out of the groove, and to reduce noise and hiss. When the signal is amplified and sent to the speakers, the frequency curve must be straightened again to give a correct sound reproduction. Therefore, an RIAA amplifier is necessary.
How does an RIAA amplifier work?
An RIAA amplifier corrects the frequency curve of the signal and amplifies it to a level that can be sent to the speakers. An RIAA amplifier works in such a way that it adapts the signal to what has been cut into the record.
How do I choose the right RIAA amplifier?
Choosing an RIAA amp depends on several factors, including your budget, the type of pickup you have, and the amp you're using. It is important to choose an RIAA amplifier that is compatible with your pickup, as different pickups require different amplifiers.
What type of RIAA amplifier should I choose?
It depends on your system and pickup. There are two types of RIAA amplifiers: MM (moving magnet) and MC (moving coil). MM amps work for MM pickups, while MC amps work for MC pickups. MC amplifiers require a higher gain than MM amplifiers due to the weaker signal. Finally, there are also RIAA amplifiers that work for both MM and MC pickups.
