# Exciter

Exciter window

The Exciter effect adds harmonics to the treble part of the audio signal. The harmonics generator is modeled after a vacuum tube.

The Frequency knob controls the frequency above which harmonics are added. For best results, only the top octave of the input signal should be used. If Frequency is set too low, the output will sound distorted rather than enhanced.

The Harmonic knob controls how hard the internal harmonics generator is driven. The higher its value, the more harmonics will be generated. If the harmonics generator is driven too hard, the signal will be limited to avoid excessive distortion, and the indicator above the knob will light. This should be avoided, as the effect is intended to add more harmonics when the signal is loud.

The Level knob controls the level of the added harmonics.

The Exciter can be set up this way:

1. Make sure the transport is running.
2. Set the Frequency and Level knobs to their maximum values, and set the Harmonic knob to its middle position.
3. Turn down the Frequency knob until you hear only the highest frequencies of the signal.
4. Adjust the Harmonic knob. If it is set too low, the level of the generated harmonics will be too low (you'll just hear a high-pass filtered version of the original signal). If it is set too high, the indicator above the knob will light during signal peaks.
5. Set the Level knob to its minimum value.
6. Turn up the Level knob until you're satisfied with the sound.
