These horizontal LED displays give an instant, intuitive check on
whether the process in each band is active, by how much, and whether
it’s expansion or compression. The amount of expansion or compression
is indicated by an easy-to-memorise 1-8 scale, with ‘8’ indicating maxi-
mum (hard) compress or expand.
Turn to set the signal threshold level above (or below) which the effect is
to take place and is used in conjunction with LED meter 11. Turning
anti-clockwise reduces the signal level needed to exceed the thresh-
old, and therefore increases sensitivity. Signals exceeding threshold
initiate the selected processing. (Above threshold mode, see 12).
Turning clockwise increases the signal level needed and reduces
sensitivity. When set fully clockwise, the threshold is set to +20dBu.
Shows the input signal level in relation to the threshold you have set.
The central orange LED lights dimly as the threshold is reached and
then glows increasingly bright as the threshold is exceeded. When the
signal causes the red LEDs to be lit, signal is above threshold. The first
green LED indicates a signal level 12dB below threshold.
