In order to verify the Input/Output Max Levels of the CLP160, need first to make
sure that
NO
RMS compression or Sub Harmonic Synthesis are active.
In order to do that need to proceed with the following steps (the details about
the RMS compressor and Sub Harmonic Synthesizer use are in the dedicated
and following section of the manual):
Sub Harmonic Synthesizer NOT Active:
1. Press the “Atk/Re/ Select” button so to turn ON the related green Led.
2. Make sure the “Atk/Re/ Confirm” is OFF
3. Move to the MIN position the THR/VAR potentiometer
4. press again the “Atk/Re/ Select” button so to turn OFF the related green
Led.
RMS Compressor NOT Active:
1. Make sure the “Atk/Re/ Select” and “Atk/Re/ Confirm” are both OFF
2. Move to the MIN position the THR/VAR potentiometer
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.
The output will never clip unless the clip is coming from the digital process.
This means that if the D/A output isn't clipped, then no clipping will come from
the Analog Op-Amp output section.
From this point of view, any position of the Output potentiometer for
evaluating the Max Input level, can be set.
Let's consider to set the output potentiometer to the position 5 of the grid in
Fig B.
Now, to define what is the Max Analog Input level, need to set the Input Level
potentiometer to a position granting enough attenuation of the signal before
the A/D, so to make sure no clip is occurring on the A/D side.
Let's set the Input potentiometer to the position 3 of the grid of Fig. A.
Done this, we can increase progressively the Input signal level until the output
will start to clip.
In this way, can be found that the Max Input level, before to get the Input Op
amps clipping is
+15dBu.
