The HyDrive HD cabinets ha a control used to adjust the level of the high-frequency driver. The switch has three positions, ON, -6dB and OFF. When the switch is set to OFF, the high frequency driver is completely out of the circuit and off. Setting the switch to –6dB, will attenuate the driver by 6dB. When set to ON, you get the full level of the high-frequency driver.
