1. VOLUME CONTROL
This control (level slider) determines the volume of the MIC.-LINE inputs 1 to 4.
2. CONTROL LED‘s AUTOMATIC SYSTEM
Green LED indicators light when the automatic system allows input signal. If the input is not addressed, the
control LED remains dark and the input „GATE“ remains closed.
3. BYPASS SHIFTER
With this switch, the feedback limiter can be switched to BYPASS, the control LED does not light up.
4. FREQUENCY SHIFT CONTROL
This control adjusts the desired frequency shift. The control range is between 3 Hz and max. 8 Hz up in the
whole bandwidth from 20 Hz to 20 kHz.
Due to the frequency shift, the „whistling sound“ (feedback between microphone and loudspeakers) oc-
curring in the signal can be additionally eliminated after the audio calibration of the system. After that, the
quality losses of the audio signal remain barely perceptible.
5. LED CONTROL SHIFTER
Lights up when the feedback limiter is switched on.
6. AMPLITUDE CONTROL (PARAMETRIC EQ)
This control, also referred to as
frequency gain, adjusts the amount of attenuation of the selected frequency.
7. FREQUENCY SELECTOR SWITCH (PARAMETRIC EQ)
This control adjusts the desired frequency for parametric EQ.
8. MULTIPLICATOR SWITCH (PARAMETRIC EQ)
Selector switch for multiplication of the set frequency by factor x1 or factor x10.
