Bass Level Knob

A Tour of the GRIP 4

GAIN REDUCTION LED Meter

The red LED meter displays the amount of gain reduction applied by the bass limiters. An increase in gain reduction – by turning the BASS DRIVE Knob clockwise - will cause the meter to light from right to left.

This knob adjusts the level of the frequencies that fall below the crossover point set by the XOVER knob, except for the sub-bass.

BASS LEVEL LED Meter

This meter indicates the level of the GRIP’s main output signal. As you increase the level by turning the BASS LEVEL knob clockwise, this meter lights amber from left to right.

LO CUT Knob

This adjusts the cutoff frequency of a steep (6-pole) high- pass filter, effectively limiting the lowest frequencies that the GRIP can output. The unit will output only those frequencies that are higher than the one set with the LO CUT knob. This knob is useful for protecting your speakers from ultra-low frequencies that may cause damage.

OUTPUT Knob

This knob controls the level of the GRIP’s total output signal from both the bass and sub-bass channels.

BYPASS Button

When you activate this button, the audio signal bypasses the Grip without being processed. This is useful when you want to compare the processed signal with the unprocessed signal. This button lights red when you enter BYPASS mode.
