In the world of audio engineering, the FET (Field Effect Transistor) compressor is a staple tool that has been used to shape and control sound for decades. But what exactly is a FET compressor, and how does it work? This blog will provide a comprehensive guide to understanding this important audio tool.
The FET compressor is a type of dynamic range compressor that uses a field effect transistor to control the gain of an audio signal. It works by using a sidechain circuit to detect the incoming audio signal, and then using the transistor to control the gain of the signal. This allows the audio engineer to control the dynamic range of the audio, reducing the loudest parts of the signal and increasing the quiet parts, creating a more balanced and controlled sound.
One of the key benefits of the FET compressor is its fast attack time, which makes it ideal for use on percussive or transient sounds. Unlike other types of compressors, which can cause audible pumping or breathing, the FET compressor is known for its smooth, transparent sound. This makes it a popular choice for use on vocals, drums, and other sources that require a fast and precise control of dynamic range.
Another advantage of the FET compressor is its versatility. It can be used as a subtle form of dynamic control, or it can be used to create extreme and creative effects. Many engineers use FET compressors to achieve classic sounds and effects, such as the “LA-2A sound” which is a warm and punchy compression style often used on vocals and bass.
In terms of usage, the FET compressor is typically used in the recording and mixing stages of the audio production process. However, it can also be used on the master bus to glue together the final mix and create a cohesive and polished sound.
In conclusion, the FET compressor is a powerful and versatile audio tool that has been used by engineers and producers for decades. Whether you are looking to achieve classic sounds or create your own unique effects, the FET compressor is a must-have tool in any audio engineer’s arsenal. So, if you haven’t already, it’s time to add a FET compressor to your collection and start exploring all of the incredible possibilities it has to offer!
