"...The SSL Listen Mic Compressor was the secret weapon in many producers sonic arsenal of recording techniques. Originally designed to prevent overloading the return feed from a studio communications mic, its fixed attack and release curves were eminently suitable for use on ambient drums mics. Of course, we?d like to take all the credit for this great sound, but as usual, it was the creativity of SSL users that led to the idea.
Now you can experience the Listen Mic Compressor within the comfort of your own workstation software and see what sounds it?ll lead you to create. If you discover something really great ? like a radical new distorted oboe sound then be sure to let us know."
