Page 5: A.g.c
The CLP260 is a Stereo RMS Compressor and Peak Limiter with the addition of a Noise Gate, an AGC, a 7 bands Eq and a Sub Harmonic Synthesizer. W i t h r e f e r e n c e t o t h e f o l l o w i n g R M S C o m p r e s s i o n p r o c e s s representation The CLP260 is implementing a REAL RMS Compressor, so compressing at the same threshold a pure sinusoidal signal as a squared wave. -
Page 6: Peak Limiter
The Hard and Soft knee feature is allowing the user to select between a sudden compression intervention when the input signal it is just above the Threshold (Hard Knee) or a smoother one starting the compression smoothly before the Threshold., Together with the RMS Compressor, the CLP260 is making available also other 2 very useful Dynamic Processes: an AGC and a Peak limiter. - Page 7 The Speed and the amount of the Expansion can be defined through the “Exp Time' and “Exp Ratio” parameters, so as the Speed and the amount of the Compression can be defined through the “Cmp Time” and “Cmp Ratio” parameters. When the Signal coming out from the AGC process (Output), applied to the AGC input, is above the “Exp Thr”...
- Page 8 In addition to the Dynamic Processes, in the CLP260 is also available a powerful Sub Harmonic synthesizer. The Sub Harmonic Synthesizer is working generating sub Harmonics on the base on the Harmonic content of the original signal. Particularly, the amplitude distribution of the generated Sub Harmonics is following the shape of a band pass filter set on the low part of the band.

Page 9: Input And Output Level Considerations
Input and Output Level Considerations The Input and Output levels of the CLP260 can be adjusted by a couple of Analog Potentiometers. Due to the fact that the potentiometers are operating in the analog domain, before the A/D converter ( Input Level) and after the D/A converter (Output Level) there is not an absolute and fixed relation between the Input and Output Levels and the levels in front of the A/D and after the D/A converters. - Page 10 In order to verify the Input/Output Max Levels of the CLP260, need first to make sure that NO process is active. Max Analog Input: in order to understand what can be the maximum Analog Input level to the unit, which is the one before the clipping of the Op-Amps in front of the A/D converters, need to make sure that no Digital clip (DSP process) is occurring.
- Page 11 Analog Bypass: de-pressing the “On/Off Process” button, the Analog Bypass can be activated. In this condition the CLP260 is bypassing the Digital section and connecting the Analog Input to the Analog Output. Here the Max Output is reaching the +10.4dBu with a GND Floor Noise of -92.3dBu, bringing the S/N of the unit to 102.7dBu Set Input and Output Potentiometers for a 0dBu Input/Output path: in order to evaluate the performances of the CLP260 RMS Compressor,...

Page 12: Getting Started
Getting Started As soon as the CLP260 is turned ON the device model name will appear in the LCD screen: CLP260 Compressor Limiter And after showing quickly the “Firmware Version 2.212”, the LCD will show the “Input Level Page, by default, where is possible see thanks to graphic meters, the Input level When the Input Level is in clipping, the symbol”>”... -
Page 13: Encoders And Enter/Quit Buttons
Encoders and ENTER, QUIT buttons The CLP260 is equipped with 2 Relative Encoders, “VARIATION” and “NAVIGATION”, These encoders allow to navigate the user interface and edit sections of the processor. They allow the user to navigate within the screen for the selection of sub-menus, pages and parameters and to select the values to be assigned during the editing operations. -
Page 14: Load/Save Preset
Load Preset: this page allows the Loading of a preset program from one of the 16factory presets (1-16) or from one of the 16 user presets: Preset 16: DeepCmp Load Preset By pressing ENTER and rotating the “VARIATION” encoder, it is possible to scroll through all current available user presets. - Page 15 Save Preset <Preset:30 EMPTY > When storing an edited configuration for the CLP260, select the location for a preset from the 16 available by using the “VARIATION” encoder. Once the desired location appears on the screen press ENTER again to reach the “Edit Name Preset”...

Page 16: Utility Function
Utility Function: this sub-menu allows to define the remote control interface [USB or MIDI] to be used for controlling the CLP260 : Preset 30: LightCmp Utility Function From “Interface Utilities”, press “ENTER” to access the “Config Communication” page, allowing to choose the remote control protocol for the CLP260. -
Page 17: Routing
Edit Parameters: in this sub-menu, the all parameters related to the signal processes of the CLP260 are available for editing. Pressing the “ENTER” button, the all processes can be accessed for editing. With the “NAVIGATION” Encoder, the all processes can be scrolled and from the “Edit Parameters”... - Page 18 In order to edit the parameters of any single process, it is enough to enter the process editing page by pressing the “ENTER” button and leaving it, once finished the editing, by pressing the “QUIT” button for going back to the Editing Parameters sub-menu and selecting the new process to edit, scrolling the all processes with the NAVIGATION encoder.
- Page 19 Note: for the all Dynamic Processes as the AGC, RMS Compressor and Peak Limiter, it is necessary, in order to make them working properly, to be in a condition similar to the one described before for the 0dBu path. Any different condition on the Input Signal, can bring to the same output results if the Input Level Potentiometer will be Adjusted in order to be close to the Input Clipping condition, which means that if the Input Signal will be lower/higher than 0dBu, the potentiometer will have to adjust the...
- Page 20 AGC Exp Thr: from this screen it is possible to set the AGC Expansion Threshold from -70 dBu up to the Hold Threshold Value; use the “VARIATION” encoder to set the value. The following is an example screen for the “AGC Exp Thr” page where the Expansion Threshold is set to -50dBu Ch.A A.G.C.
- Page 21 AGC Exp Ratio: from this screen it is possible to set the AGC Expansion Ratio from 1 up to 2; use the “VARIATION” encoder to set the value. When the Expansion Ratio is set to 1, actually there is no possibility to expand the signal, meaning that the signal amplitude can be multiplied for a coefficient not higher than 1.

Page 22: Filters 1-7
Filters 1-7: the CLP260 is providing also a 7 bands Eq. For the adjustment of the Input Signal. Particularly, the first filter of the Eq. Can be selected to be a 1st/2nd Ord. Hp or a 1st/2nd Ord. Low Shelving, the seventh filter can be selected to be a 1st/2nd Ord. - Page 23 Sub Harmony: the Sub Harmonic Synthesizer is a particular process, already introduced in the first part of the manual, that isn't actually related to the RMS compression one. The Sub Harmonic Synthesizer is intended to be an “extra” process available to the user there where the RMS Compressor is chosen for processing a source addressed to a “background”...

Page 24: Drive
This is due to the fact that extend the same amplitude to the all sub harmonics generated, would bring to a “booming” and “dark” result, there where having a Peak on the 65Hz(24-36) or 90Hz(36-56), will leave the max intensity of the synthesized sub harmonics, in correspondence of the original fundamentals, ranging around 130Hz and 180Hz, where typically fall the octave used by the harmonizing instruments as the Bass or Kick Drum, creating there a bigger presence and giving the music that much... -
