Rocktron Blue Thunder - Manual (Page 17)

Functions and Parameter Descriptions
The first function displayed when turning the FUNCTION SELECT control
is the Global function. The parameters provided in this function affect all presets
(i.e. the settings stored for these parameters are the SAME for all presets).
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 ***GLOBAL***
appears on the display.
The PARAMETER SELECT control will allow you to access each of the following
Global parameters:
The PARAMETER ADJUST control will allow you to adjust each of the GLOBAL
parameters:
GLOBAL
Function
)HP Filter
HP CUT
OUTPUT
HUSH OFFSET
MUTE
DIRECT
The HP FILTER parameter allows you to select (with the PARAMETER ADJUST control) either
ACTIVE or OFF for that particular preset.
Selecting ACTIVE will route the signal through the hi pass filter section (controlled by the HP CUT
parameter). Selecting OFF will bypass the HP CUT parameter (although the HP CUT parameter will
be displayed when adjusting the PARAMETER SELECT control, it will be bypassed).
The HP CUT parameter allows you to select (with the PARAMETER ADJUST control) the amount of
low frequency content that gets passed into the effects processing section of the Blue Thunder. The dry
signal content remains uneffected at full bandwidth, with EQ when DIGITAL is selected for the Dry
Path.
Selecting 80 HZ sends all frequency content above 80 HZ into the effects processing section.
Selecting 160 HZ sends all frequency content above 160 HZ into the effects processing section.
Selecting 240 HZ sends all frequency content above 240 HZ into the effects processing section.
Selecting 320 HZ sends all frequency content above 320 HZ into the effects processing section.
NOTE!!
While the HP FILTER ON/OFF parameter is global, the HP CUT selection is per preset.
The OUTPUT parameter determines whether the output of the Blue Thunder is a stereo (left and right)
signal or two mono signals.
The HUSH OFFSET parameter allows you to globally (all presets) adjust the HUSH ® Expander
Threshold. This means that if this parameter is altered from 0dB to +3dB, the Expander Threshold will
be 3dB higher for all presets. This feature can be useful when switching from a quiet guitar with
passive electronics to a noisy guitar with active electronics - as the active guitar would require a higher
Threshold level in all presets.
The MUTE parameter allows you to mute the output of the Blue Thunder. This feature is especially
useful when changing guitars during a live set. When the Blue Thunder is muted, front panel controls
are disabled. However, a MIDI program change will disable the mute (mute = out) and execute the
program change. The MUTE parameter can be assigned to a MIDI controller number for use with a
MIDI device (such as a Rocktron All Access or Rocktron MIDI Mate).
The DIRECT parameter determines whether the direct signal is switched in or out of the signal path.
When using the Blue Thunder in a parallel effects loop, it is recommended that the direct signal is
switched out - thereby providing 100% wet (effect)output - allowing you to use the effects mix
control of your amplifier/preamp.
