5.3.5 Parametric equalizer

In addition to the high pass filter and low pass filter, each output
channel provides ten filters that can be individually adjusted and thus
offer a wide range of sound processing options .
1) Select the channel to be set .
2) Call up one of the ten filters
3) Set the filter frequency

5.3.6 Signal delay

For each output channel, a signal delay can be defined (e . g . to com-
pensate different distances between speakers and audience) .
1) Select the channel to be set .
2) Call up the function
Delay
3) Set the delay value . To change between milliseconds (
( ) and millimeters / meters (
Feet
SELECT/ ENTER . When you enter a distance, the processor will cal-
culate the delay time based on the speed of sound .

5.3.7 Level limiter

With the limiter, the signal can be quickly limited to an adjusted level .
This will prevent overloads in the power amplifiers and will protect
the speakers against damage .
The limiter will respond to the peak values of the signal .
1) Select the channel to be set .
2) Call up the function
3) Set the threshold value
When this threshold value is exceeded, the gain will be reduced .
Note: To deactivate the limiter, set the threshold to its maximum value (9 dBu) .
4) Set the release time

reach its original value after the signal has fallen below the thresh-
old value . The release time depends on the gain attenuation and
is specified in dB/s .

5.3.8 Phase reversal

The signal of an output channel can be inverted (phase reversal), e . g .
to correct a reverse polarity of speakers connected .
1) Select the channel to be set .
2) Call up the function
3) Select if the signal of this output is to be inverted (
not (
