Introduction The Auto-Dynamic De-Esser is a highly specialized audio tool. It is used to reduce S-frequency of speakers and singers. It should perform without disturbing natural character and timbre of the voice. This is not an easy task. SPL has developed a new circuit design that combines ease of use with natural sounding and effective performance. How do traditional De-Essers work? Traditional De-Essers use compressor-technology. The control elements are a threshold control and a frequency control.
Connections Switch off power of all units to be connected before you connect the Auto Dynamic De-Esser. The Auto Dynamic De-Esser is fitted with both XLR-connectors and TRS stereo jacks for balanced operation, though the jacks may be used with unbalanced connections simply by plugging in mono jack-plugs. The level difference that normally occurs when a balanced input or output is used unbalanced is automatically compensated for.
Control Elements 1 1 S-Reduction 2 Auto-Threshold 2 3 4 S-Reduction controls the intensity of the de-essing effect. The LED-display shows the gain reduction of S-frequencies in a range between 0dB to -20dB in 2dB steps. S-REDUCTION adjustments between 3 and 7 have proven to create best results in practical applications. AUTO-THRESHOLD activates a new function that automatically readjusts the threshold when the input gain varies due to varying distances of the speaker to the microphone.
Control Elements The Male/Female-switch lets you select two different operation modes: The female mode is chosen when the switch is pressed and the status-LED illuminates. The automatic S-frequency recognition is set to the characteristics of female voices. The opposite position of the button switches to the male mode. The S-frequency recognition is then set to the characteristics of male voices. However, it may sometimes be necessary to use the MALE mode and female vocals and vice versa.
