Intel Peavey ReValver MK III - Manual (Page 28)

Speakers / cabinets
A module from this category is usually placed after any amp module.
Module name = Convolution speaker simulation
Description = This module uses real-time convolution to mimic actual speaker and cabinet
setups. Convolution can be very CPU-intensive so there are 2 optimization options, “Resample”
and “Hi-Res.” Forcing downsampling of the signal reduces the CPU utilization to an amazing 25%,
while still retaining virtually the same tonal quality. (This is possible because Guitar speakers
generally do not have a frequency range of more than 5-6 kHz.) The available speakers and cabi-
nets were sampled with several microphones placed at varying angles. One sampling (an “Im-
pulse Response”) is a fixed moment in time and cannot be adjusted. The Load button allows you
to import your own Impulse Responses in .wav format.
Module name = Speaker Construction Set (SCS)
Description = Select from any of the predefined speaker models and put them in a cabinet with a
physical size of your choice. This simulated speaker cabinet is then miked by any of the 20 micro-
phone configurations. (This technique is considerably less CPU-intensive than the RIR convolu tion
module.) Remember, ReValver MKIII is capable of building virtual speaker cabinets that really
cannot exist in the physical world, and depending on which components and settings you’re
change, you could end up with some very “unique” sounds.
