4. Diffusion
The DIFFUSION button controls how much the sound is diffused, or spread apart, as it recirculates in the
reverberators. The amount of diffusion is also adjusted automatically by the reverb time control; greater
diffusion is inherent in longer reverb times. The DIFFUSION button lets you adjust the amount of diffusion to
suit your musical context. A higher diffusion setting will usually make the reverberant sound more full or lush.
5. Reverb Time Contour
The REVERB TIME (RT) CONTOUR buttons change the frequency response of the reverberators and hence the
tonal quality of the reverb tail. The LOW RT CONTOUR setting determines whether frequencies below about
1kHz are boosted or attenuated. If the X1 LED is illuminated, the low frequencies are not altered. If the X1.5
LED is illuminated, low frequencies are boosted relative to the overall frequency content of the reverb signal.
If the X.5 LED is illuminated, low frequencies are reduced or attenuated. The HIGH RT CONTOUR setting
works in a similar manner, but operates on frequencies above about 10kHz, and only provides settings for
attenuation. Click the LOW and HIGH buttons to cycle the RT CONTOUR LEDs through the different settings.
The RT CONTOUR controls let you tailor the sound of the reverb to make it fit tonally with your music. You
can also use them to make the reverb less boomy (or more), and less bright and sizzly.
6. Rolloff
The ROLLOFF control reduces (or rolls off) high frequencies as they recirculate in the reverberators. Like the
HIGH RT CONTOUR control, it lets you make the reverberant signal less bright and obtrusive. The low setting
produces the greatest reduction of high frequencies. Click the button to cycle the LEDs through the different
settings.
7. Level Controls
The INPUT LEVEL slider adjusts the amplitude (loudness) of the signal entering the plug-in. You can use it to
amplify a weak signal or attenuate a loud one. The slider has a range of -60dB (nearly silent) to +3dB (a mild
amount of boost). When the slider is positioned near seven on the printed scale the input signal is passed with
unity gain.
The simulated LED meters to the left of the INPUT LEVEL slider show the approximate peak levels of the input
signal. The meters reflect the level of the signal after it has been attenuated or boosted as determined by the
INPUT LEVEL slider, so watch them as you adjust this slider. Ideally the loudest signal peaks should cause the
0dB LED to illuminate briefly, and the +3dB LED should never light up.
