8 BLOCKS GUIDE

DYNAMICS PAGE
Input Dynamics
– Sets the strength of an input dynamics processor. When set below zero, the amp type
compresses, resulting in a smoother, less dynamic sound. When set greater than zero, the amp expands, resulting
in a punchier, crunchier and more dynamic sound. Note that extreme values can have undesirable side-effects
such as pumping or clipping.
Output Compression
– This controls the ratio of a compressor specifically tailored to reduce the output
dynamic range of the amp block. A gain reduction meter shows the amount of compression when this parameter
row is selected.
Compressor Type
– Sets the type of Output Compression. The “OUTPUT” type simply compresses the output.
The “FEEDBACK” type likewise compresses the block output, but also applies dynamics to the input of the block,
so you will also get more distortion as you play harder and less when you play softer or roll back the volume.
Compressor Threshold
– Sets the threshold of Output Compression. A lower value causes compression to
occur for quieter signals.
Compressor Clarity
– Used in conjunction with the other Output Compression parameters, this adjusts the bass
response of the compressor and can be used to add clarity to the low end. Output compression must be above
zero for this to have any effect.
Speaker Compression
– Duplicated control from the Speaker page.
Speaker Time Constant
– This adjusts the thermal time constant of the virtual voice coil, affecting the attack
and release of virtual Speaker Compression. Lower values cause the voice coil to heat and cool faster and vice-
versa.
Dynamic Presence
– This models output transformer leakage inductance, resulting in a brightening of the
tone when the virtual power amp is pushed. When playing softly or at lower gains, the influence of this control
is lessened. Note that this only affects the power amp modeling and is dependent on the degree of power
amp overdrive. This control can also be set negative to cause the tone to darken when playing harder. This can
help dial in the sweet spot of an amp model. As the Master is increased, an amp becomes more liquid, more
compressed and easier to play. However, the highs may get overly compressed, causing the amp to sound too
dark. Dynamic Presence allows you to get the desired power amp drive and feel without high frequency loss.
Dynamic Depth
– Analogous to Dynamic Presence, above. This increases low frequencies when the virtual amp
is being pushed. While real amps don’t display this behavior, it is a cool tone-shaping tool.
Level
– Duplicated control from the Tone page.

ADVANCED PAGE
Input Select
– The Amp block processes audio in mono. This control determines how incoming stereo signals
will be processed. You can input only “LEFT” or “RIGHT” channels, or “SUM L+R” (the default setting).
Input Trim
– Duplicated control from the Tone page.
EQ Type
– This determines the number of bands for the amp block’s built-in graphic equalizer, and whether it will
be variable Q, constant Q, passive or console type. You can change this from the Output EQ page using the
NAV
UP
/
DOWN
buttons.
EQ Location
– Sets the position of the equalizer controlled by the Post EQ page. The default value of “OUTPUT”
places the EQ at the output of the virtual power amp. “PRE PA” places the EQ between the preamp and power
amp. The “INPUT” setting actually moves the Post EQ to the location of the Pre EQ: in front of the preamp.
