LIMIT indicators
Limit active LED’s
Fig 1-11: RM-CA2 & RM-CAD8 Meters & Phase Error LED
The LIMIT indicators are an additional function of the left hand LED (-34 VU) of the meter
scales. When the level potentiometer gain is applied to the incoming signals the resulting
signal can exceed the maximum input levels into the D-class amplier. To avoid clipping
or overow conditions a limiter function is applied. The limiter is applied independently to
each channel and has an instantaneous attack with a slow release.
While the limiter is active the left hand LED will ash. If the LED is continually ashing then
the level potentiometer setting should be reduced so that the LED is always on or only
ashes infrequently.
Note that for the limiter to be required the incoming signal level will need to exceed 0dB
(VU -4). If the left hand LED is ashing but the meter levels are low then the incoming
signal is lower than VU 34 and this does not indicate a limiter function.
