SOFTWARE RANGE „NOISE GATE“
„
Threshold
“
The noise gate cuts signals under a determined, defi-
nable (-90 dB to -24 dB) level. Signals above this level,
however, are passed through unprocessed.
A typical use is the suppression of noise with low level.
Thus the controllable threshold level (threshold set-
ting) is adjusted directly above the interference level.
Possible existing noise is hereby suppressed as soon as
the master volume of the input signal falls below the
threshold setting.
If the master volume is above the TH-setting, indeed
also the interferences are passed through, but covered
by stronger wanted signals.
SOFTWARE PROGRAMMING
„FEEDBACK SUPPRESSOR“ feedback limiter
In the menu „
FEEDBACK SUPPRESSOR
“
(feedback limiter) an automatic feedback suppressor
(adaptability) or a digital phase shift can be allocated
to an output.
MODES:
(
adaptability
)
Feedback reduction: for an ultrafast automatic feedback
suppression ten precise notch filters are available, which
automatically find and reduce feedbacks.
MODES:
(p
hase shift
)
The frequency for the phase shift of the shifter can be
determined using „Frequency“.
FREQUENCY
, setting of the shifter frequency:
- 1.7 Hz
- 2.0 Hz
- 3.0 Hz
Useful information:
At first you should reduce the parasitic feedback frequencies with the parametric EQ for a favoured value (dB) narrowband (
OCT.
).
Produce a feedback by raising the microphone sensitivity. Measure the occuring frequency and correct it again with the
parametric EQ.
After the signal „correction“ the automatic feedback limiter (adaptability) or the digital
SHIFTER
can be activated.
Useful information:
Please select the favoured „PRESET“. Two PRESET configurations can be
carried out for all programming processes.
