Max  Analog  Output

:  once  set  the  Max  Input  Level  to  +15dBu,  in  order  to 

identify  the  Maximum  Output  Level,  need  to  move  the  Input  Level 
Potentiometer  from  the  position  3,  up  to  the  position  that  is  clipping  the  A/D 
converter.
With +15dBu Input, the position of the Input Level Potentiometer at the limit of 
the Input Clipping (notified when occurred by the RED CLIP LED ), is the position 
6 of the Input Level grid of Fig A.
Once set, then, the Input Level Potentiometer to the position 6, in order to find 
out the Max Output Level achievable with the CLP160, need to set the Output 
Level Potentiometer to the position Max 
The Max output Level that can be found is +9.8dBu, that is also indicated by the 
Led Meters of the Front Panel, showing in fact the CLP160 OUTPUT LEVEL.

CLP160 Signal to Noise Ratio (S/N)

: from the condition got for the Max Analog 

Output verification, can be go the S/N of the CLP160.
If,  with  the  Max  Output  Level  of  +9.8dBu,  the  Input  Signal  Is  removed, 
measuring the output can be seen that the residual Ground Floor Noise drops to 
-90.3dBu,  which  let  us  say  that  the  S/N=(Max  Output)  –  (GND  Floor  Noise)  = 
9.8dBu - (-90.3dBu) = 100dBu

Analog  Bypass

:  de-pressing  the  “On/Off  Process”  button,  the  Analog  Bypass 

can be activated.
In this condition the CLP160 is bypassing the Digital section and connecting the 
Analog Input to the Analog Output.
Here  the  Max  Output  is  reaching  the  +11.4dBu  with  a  GND  Floor  Noise  of  -
91.6dBu, bringing the S/N of the unit to 103dBu

Set Input and Output Potentiometers for a 0dBu Input/Output path

: in order 

to evaluate the performances of the CLP160 RMS Compressor, we'll set a 0dBu 
path,  and  to  that  one  we'll  refer  the  all  measurement  we'll  show  for  making 
understanding the Unit's way of working.
What  anyway  will  be  shown,  will  remain  valid  for  any  input  level  value  there 
where with the Input Level Potentiometer, the signal to the A/D will be adjusted 
so to be close to the Clipping (notified by the RED CLIP Led).
In  order  to  be  on  a  0dBu  Input/Output  path,  when  the  Unit  is  in  “Process 
Bypass”,  need  from  the  previous  condition  to  set  the  external  Analog  Input 
Signal to 0dBu.
In order to get in Output also 0dBu, being at the maximum A/D Input level, need 
to  set  the  Input  Level  Potentiometer  to  7  of  the  Grid  of  Fig  A  and  the  Output 
Level Potentiometer to the position 7 of the Grid of Fig B.
The Output Led Meter will indicate 0dBu.
