64 Chapter 9 Reverb
PlatinumVerb
The difference between the PlatinumVerb and the GoldVerb is the former’s enhanced
Reverb section. The Early Reflections sections of the two plug-ins are identical. For more
information, please read the “GoldVerb” section, on page 61. We’ll focus on the
additional features offered by the PlatinumVerb in this section.
The Reverb section of the PlatinumVerb is based on a genuine dual-band concept. This
is to say that the on-board frequency crossover splits the incoming signal into two
bands, which are then processed with reverb in two separate modules.
Parameters of the PlatinumVerb
Crossover
This is the frequency that the two frequency bands are split at, for separate processing.
Low Ratio
This parameter determines the reverb time of the bass band. The Reverbtime parameter
applies to the high band. At 100%, the reverb times for the two bands are identical. At
lower values, the reverb time of the frequencies below the crossover frequency is
shorter. At values greater than 100%, the reverb time for low frequencies is longer.
Both of these phenomena occur in nature. In most mixes, a shorter reverb time for bass
frequencies is preferable. As an example, if you’re using the PlatinumVerb to put reverb
on a drumloop featuring kick and snare drums, a short reverb time for the kick drum
allows you to set a substantially higher wet signal.
Low Level
This knob determines the level of the bass reverb. At 0 dB, the volume of the two
bands is equal. The bass reverb level can be boosted by up to 12 dB and attenuated by
up to 100 dB.
