SOFTWARE CONFIGURATION
Information for installation and operation:
Useful information
:
Repeat the measuring- and adjustment procedure until
there is a linearity (see drawing No 2).
In big halls or in case of higher distance from the signal
sources (f.i. speakers) a treble dropout will happen. For
rooms with reverberation it is senseful to concentrate
additionally on the equalization of low frequencies up to
100-800 Hz. In this frequency range eich is the biggest
reverberations.
It has been shown that one should go with a lot of feeling
in the equalization zoom. It should in this case always
the efficiency of the loudspeaker and the amplifier are
considered.
Equalization for feedback suppression
The positive feedback between the microphone and
speaker generates the so-called feedback loop that
begins always at the frequency at which the transmission
curve has the strongest peak. This can be damped by
the power in the voice amplifier integrated limiter and
automatic feedback in Digivoice systems by correcting
with PEQ as follows:
First, try to reduce the disturbing frequency with the
parametric EQ to a desired value (dB) narrowband (OCT).
Then, create a feedback by increasing the microphone
sensitivity. Measure the frequency occurring and correct
them with the parametric EQ.
Then in support for mobile frequencies in Powervoice
automatic power mixer, a automatic „FEEDBACK
SUPPRESSOR“ (adaptability) to be connected.
MODI: (adaptability) VOICE POWER SYSTEM AMP
Feedback Reduction: available for a super-fast automatic
feedback suppression
ten precise notch filters are available, which are
automatically and reduce feedback
