Alesis Legacy Series Audio Processor Synthesizer user manual Xover OUT Button, SUB Bass Level Knob

4 A Tour of the GRIP

When using the GRIP on program material – such as a CD or LP - you should set the XOVER knob to a low setting so that the unit doesn’t process the vocals or other lead instruments. For your reference, the graphs at the right provide examples of typical frequency response curves for bass, kick drums and vocals.

XOVER OUT Button

This button toggles a high- pass filter on the main outputs. When you engage the button, frequencies falling below the setting of the XOVER knob are removed from the main outputs (but are still present in the XOVER output). This allows you to separately route the sub- bass present in the GRIP’s signal.

When the XOVER button is not engaged, the main outputs carry the GRIP’s total output signal, limited only by the LO CUT knob.

SUB BASS LEVEL Knob

This controls output level of the GRIP’s sub-harmonic synthesizer. This signal consists of the bass frequencies produced by the GRIP that were not present in the original signal.

BASS DRIVE Knob

This knob controls the action of a pair of multi-band limiters acting on the Bass and Sub-Bass signals. You should treat it as a tone control. Turning the knob clockwise gives you a rounder sound with longer sustain, and turning it counterclockwise gives you a faster, more dynamic sound.
