Stereo bus compressor
You often hear that people like to use a compressor on their stereo master bus. Historically large format mixing consoles often had a high quality compressor built in that you could assign to the stereo master bus. A classic example would be the SSL compressor as found in the master section of the mixing console. This is a well known compressor and it has a fairly clean yet aggressive character when set to it’s fastest time constants. This is a stereo bus compressor that is often used on rock mixes to give them a little extra drive and punch. It can however be set just to tickle the music and gently apply gain reduction on peaks in the programme material.
