When it comes to professional audio production, understanding different types of compressors is essential for shaping dynamics, enhancing clarity, and achieving a polished sound. Whether you're mixing music, mastering a track, or working on post-production audio, the right compressor can make all the difference. Here are the essential compressor types you should know:
1. VCA Compressors (Voltage Controlled Amplifier)
VCA compressors are known for their precision and transparency, making them ideal for controlling dynamic range without colouring the sound. They excel in drum busses, vocals, and mastering chains where consistency is key
Examples: SSL G-Series Bus Compressor - dbx 160 - API 2500
2. Optical Compressors
Optical compressors use a light source and a photocell to control compression, resulting in a smooth and musical compression characteristic. They're often preferred for vocals and bass guitars due to their gentle response
Examples: Teletronix LA-2A - Avalon VT-737
3. FET Compressors (Field Effect Transistor)
FET compressors are fast and aggressive, perfect for adding punch and attitude to drums, guitars, and rock vocals. They impart a distinct colour and character to the sound
Examples: UREI 1176 - Purple Audio MC77
4. Variable Mu Compressors (Tube Compressors)
Variable Mu compressors, often referred to as tube compressors, use vacuum tubes for compression, adding warmth and harmonic distortion. They work well for mastering, vocals, and buss compression where musical coloration is desired
Examples: Manley Variable Mu - Fairchild 670
5. Digital Compressors
Modern digital compressors offer flexibility and precision with advanced features like sidechain filtering, lookahead, and multiband compression. They can be transparent or coloured depending on their design.
Examples: FabFilter Pro-C2 - Waves C1
When to Use Each Compressor Type:
Vocals: Optical for smoothness, FET for aggressive character (Often used in series)
Bass: Optical for smoothness and fattening up, FET for aggressive character
Drums and busses: VCA for control, FET for punch
Mastering: VCA for precision, Variable Mu for warmth
