4 1. INTRODUCTION Y ou are now the Owner of an CLE 8.0 Compressor/Limiter/Gate. The CLE 8.0 is a very powerful dynamic processor . LT O We have included in it several innovative circuit designs that make the CLE 8.
5 2.1.2 Introducing Audio Dynamics Chart.1: The dynamic range capabilities of various devices Chart.2: The interactive relationship between the operating level and the headroom 2.
6 2.1.4 More about noise: Expanders and Noise-Gates A lot of instruments such as microphones, amplifiers, guitar pickups, etc generate some noise, either at low fre- quencies (hum) or at high frequencies (hiss) Such noise will inevitably interfere with the quality of your audio signal.
5. SC Filter switch Engaging this switch to insert a Low-cut filter in the sidechain path and thus limits the influence of low frequencies on the CLE 8.0's control processes. 6. Smart switch Engaging this button to switch the "Hard Knee" characteristics to SKC (Smart Knee Control).
