“Attack Time [A]”
- the selectable range of the Peak Limiter’s Attack Time is from 5ms to 200ms, in steps
of 1ms from 5ms to 20ms, then in steps of 5ms from 20ms to 30ms, then in steps of 10ms from 30ms to
100ms, and then in steps of 20ms from 100ms to 200ms.
The Limiter’s Attack Time can be adjusted by rotating the “NAV/PM1” encoder.
“Release Time [R]”
- the selectable range of the Peak Limiter’s Release Time is from 0.1s to 3s in steps of
0.1s and can be adjusted by rotating the “PM2 encoder.
”
“Limiter Active Threshold”
- the selectable range of the Peak Limiter’s Threshold is from +20dB (Limiter
not active) to -10.0dB in steps of 0.2dB and can be adjusted by rotating the “PM3” encoder.
Note
: The Peak limiter Threshold is defined in Vp, due to the fact that with both, Sinusoid and Squared
wave testing signals, the DS-CP25 Peak Limited output Vp (Peak-Peak) Level is the same and matching
the selected one.
Note1
: Once the desired options have been selected using the 3 encoders, they are automatically saved as
current and stored in the DS-CP25 system status once leaving the page.
Note2
: to exit this page, push the “ESC” button.
It’s useful to note that the Limiter implemented on the DS-CP25 before the final output is a
PEAK LIMITER
.
This kind of Limiter acts upon the Signal Peak detection and therefore the limitation is on the Output Peak
value.
This kind of Limiter, as illustrated by the picture here above, is useful for the amplifier’s and Loudspeakers’
protection.
