The Effect of the Shape ControlThe HS1200’s unique Shape control enables the sound of your bass instrument to beenhanced at the touch of a button. When the front panel Shape switch is pressed in, aspecial equalization curve is activated that is designed to improve the sound of mostelectric bass instruments. This curve provides moderate boost at certain frequencyareas and deep attenuation at other frequency areas. Furthermore, the front panelShape control adds a filter to a selected frequency area within the Shape curve. Asthe Shape knob is turned clockwise, the filter is imposed on higher frequency areas;as it is turned counterclockwise, the filter is imposed on lower frequency areas. At thefully clockwise position, the filter is applied to the 1 kHz frequency area; at the fullycounterclockwise position, the filter is applied to the 80 Hz frequency area.Even when Shape is activated, the front-panel EQ controls remain operational. Whenall three EQ controls are set to their “0” (flat) position, they add no boost or attenua-tion to the preset Shape curve. However, when any EQ controls are turned left or rightof their 12 o’clock (“0”) position, their boost or attenuation effect is superimposedupon the preset Shape curve. In this way, you can customize the sound of the HS1200further still to complement your particular bass instrument and playing style.Note that, when the Shape switch is out, the EQ controls operate on the “flat” signalcoming from your bass (that is, there is no preset equalization curve imposed).ENGLISH14
