Low Frequency Control The Low Frequency control adjusts a shelving filter with a selectable corner frequency of either 40Hz or 120Hz. The low shelving filter designed into the T ube EQ affects all frequencies below the corner frequency when applying boost or cut.

The outer control is used to select a frequency while the inner control is used to apply +/-12dB of gain. The Hi-Mid control can cover two fre- quency ranges depending on the position of the Shift x 10 switch.
