            <h2>Functionality</h2>
            <p>
                A Bass Enhancer is used to produce very low sound that is not present in the original signal. This is done by creating harmonic distortions of the signal which are restricted in range and added to the original signal. A Bass Enhancer raises the lower end of an audio signal without simply raising the lower frequencies like an equalizer would do to create a more "fat" or "boomy" sound.
            </p>
            <h2>Tips</h2>
            <ul>
                <li>Use the enhancer in the master channel of your audio suite to bring some low end, bassy or full sound to your mix</li>
                <li>Add back some bass to old digitalized recordings</li>
                <li>Let your bassdrum microphone produce big and bassy boom</li>
                <li>Listen closely to the harmonics to not create "muddy" or "rumbling" low frequency range</li>
                <li>Use the floor to narrow down the lower end to the required range</li>
            </ul>
            <h2>Controls</h2>
            <ul>
                <li><strong>Bypass:</strong> Don't process anything, just bypass the signal</li>
                <li><strong>Input (knob):</strong> Control the input level before the signal is processed</li>
                <li><strong>Input (V/U meter):</strong> The level after the input knob</li>
                <li><strong>0dB:</strong> Flashes if input level rises above 0dB</li>
                <li><strong>Output (knob):</strong> Control the output of the plugin - clipping could destroy your signal</li>
                <li><strong>Output (V/U meter):</strong> The level after processing and after the output knob</li>
                <li><strong>0dB:</strong> Flashes, if the signal rises about 0dB in the output stage</li>
                <li><strong>Amount:</strong> The amount of harmonics added to the original signal</li>
                <li><strong>Listen:</strong> Mute the original signal and listen to the harmonics exclusively</li>
                <li><strong>Harmonics:</strong> The amount of newly created harmonics</li>
                <li><strong>Blend Harmonics:</strong> The "colour" (or octave) of the harmonics</li>
                <li><strong>Harmonics Level:</strong> The amount of created harmonics</li>
                <li><strong>Scope:</strong> The frequency harmonics are produced above</li>
                <li><strong>Floor (button):</strong> Constrain the enhancement on the lower end</li>
                <li><strong>Floor (knob):</strong> The frequency no harmonics are produced below</li>
            </ul>
