Rocktron Blue Thunder - Manual (Page 22)

Compression is often used to maintain an even level when using clean
tones, and is also used to increase sustain when using high gain distortion.
To access this function you must first press the “EDIT” button to enter into the
“EDIT MODE”and turn the FUNCTION SELECT knob to the right until COMPRES-
SOR appears on the display.
The PARAMETER SELECT control will allow you to access each of the following
Compressor parameters.
The PARAMETER ADJUST control will allow you to make adjustments to be
made to the selected parameter:
Functions and Parameter Descriptions
COMPRESSOR
Function
The COMPRESSOR I/O parameter determines whether the compression circuit is active or
bypassed for the current preset.
Select IN if you want activate the compressor
Select OUT if you want to bypass the compressor
The COMPRESSOR THRESHOLD parameter determines the input level (in dB) at which
compression will begin. Lower settings of this parameter will result in more compression.
The COMPRESSOR ATTACK parameter determines the speed (in milliseconds) at which the
compressor will reach its maximum compression level after the input signal has exceeded the
threshold level (set by the COMPRESSOR THRESHOLD parameter).
The COMPRESSOR RELEASE parameter determines the speed (in seconds) at which compres-
sion will cease after the input signal has dropped below the threshold level.
***NOTE - We suggest you use longer release times - up to 1 to 2 seconds. This will keep the
dynamic range limited producing a more smooth consistent level output.****
