T ABLE OF CONTENTS 1. INTRODUCTION......................................................................................................................................4 2.1 Some technical stuff 2. THE CONCEPT BEHIND...................................
1. INTRODUCTION Y ou are now the Owner of an CLE 4.0 Quad Compressor/Limiter . The CLE 4.0 is a very powerful dynamic LT O processor . We have included in it several innovative circuit designs that make the CLE 4.
5 Chart. 1 The dynamic range capabilities of various devices Chart. 2 The interactive relationship between the operating level and the headroom So the operating level must be as high as possible but not high enough to generate distortion. T ricky uh? There is a very easy way to obtain this.
6 3. CONTROL ELEMENTS Y our CLE 4.0 presents with four channels. Each channel is equipped with the same control elements: 3 push-button switches, 4 rotary controls and 17 LEDs. Y ou can operate in stereo mode via pressing the Couple switch. The details please refer to following content.
7 9. Threshold Control for Limiter The threshold Level for the Limiter will be adjusted by this control 10. Limiter LED When the Limiter is active, this LED will flash up. 12. V oltage Selector and Fuse holder Please make sure about the voltage available in your Country before connecting the unit to the AC socket.
8 4.1.2 Ratio ontrol C This control sets the change of input level to output level but only for the signals that exceed the threshold. The scale of the ratio control on the front panel (calibrated in dB) indicates how much input level is required to increase the output level by 1dB.
4.2 The Peak Limiter Section How fast is the compressor to react to a signal which is above the threshold point? This is determined by the attack time. A longer attack time is advisable to process low frequencies while shorter attack time is preferable for high frequencies.
10 b. In Line Connection Please see following drawing for details. 5.3 Rack ounting M The most secure mounting is on a universal rack shelf available from various rack manufactures or your music dealer . The CLE 4.0 Quad Compressor/Limiter fits into one standard 19" rack unit of space.
