6.
FRONT SIDE OF THE AMPLIFIER
1. CONTROL LEDs AUTOMATIC SYSTEM
Green LED indications light when the automatic mic. system allows an input signal. If the input is not responded, the green
control LED remains dark and the input remains closed. Please possibly consider the DIP switch position.
2. CONTROL LEDs PEAK
Red LED indications light when the input signal is too high and the input is overridden. In case of override please change GAIN
LEVEL or DIP switch position (MIC.-LINE).
3. CHANNEL VOLUME CONTROL 1 to 9
These controls (level slide controls) determine the volume of the inputs 1 to 9. Please consider the volume controls (limiters) in
the display (settings 1-4 VOL, DSP) and the MASTER control or GAIN-LEVEL potentiometer at the rear side.
4. LINE INPUT
Line input (0 dB) with level slide controls,
LF and HF-EQ
controls for f.i.
CD player feed etc
. (front input).
5. DeEsser (basics)
If a transmission of the human voice is carried out, it is often necessary for aesthetic reasons, subsequently to raise or to drive
the high frequency parts of the reproduction (approx. 2 kHz to 8 kHz) by means of an equalizer.
Thereby the voice gets a more robust sound or more presence.
Also for pure speech transmissions thereby a voice appears more direct to the most listeners and attracts more attention with
the same volume.
A problem occurs with raising the high frequencies of a speech transmission, as the voiceless sibilants (
s, ss, ß, sch, z, tz
) almost
exclusively consist of such frequencies, by amplifying these areas they are reproduced disproportionally loud.
Besides this, this effect is intensified by the often used compression of the speech signal, as these sounds are indeed perceived
as loud, but regarding the technical signal level they are low and can hardly be driven by the compressor.
Insofar a reproduction processed in this way sounds very unpleasant, as the sibilants are noticed disproportionally loud and
very intrusive.
