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" and below the "Thr Hold", it is
expanded up to the max expansion coefficient defined by the Exp Ratio.
When the Signal coming out from the AGC process (Output), applied to
the AGC input, is above the "Cmp Thr", it is compressed up to the min
compression coefficient defined by the "Cmp Ratio".
When the AGC output is comprised within the "Thr Hold" and the "Cmp
Thr" Thresholds, no further expansion or compression actions will be
taken and the expansion/compression coefficient, will be maintained with
its current value.
Particularly, if the averaged AGC output level is "entering" the signal
"hold" area coming from the expansion area, then the Coefficient
computed by the AGC for multiplying the input level in order to get the
proper output signal, will be higher than one (if the "Exp Ratio" will be set
at 1:2), so as the coefficient will be lower than one (if the "Cm Ratio" will
be set between 2:1 and 16:1) if the averaged AGC output level is
"entering" the signal "hold" area coming from the compression area.
The last dynamic process available with the CLP260, is a Peak Limiter,
useful when the CLP260 is used before an amplifier and need to limit the
signal for avoiding the amplifier to overload and break cabinets.
This kind of Limiter is acting on the Signal Peak detection and therefore
the limitation is on the output Peak value.
