Rocktron Blue Thunder - Manual (Page 29)

Functions and Parameter Descriptions
The Chorus effect in the Blue Thunder is produced by detuning two delayed
signals (Voice 1 and Voice 2), then modulating the detune effect so that the amount
of pitch detune is constantly varying. Using different detune amounts, modulation
rates, modulation depths and pan settings for each delayed signal will produce a
greater perceived spaciousness.
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 ***CHORUS***
appears on the display.
The PARAMETER SELECT control will allow you to access each of the following
Chorus parameters
The PARAMETER ADJUST control allows you adjust the selected parameter:
CHORUS
Function
The CHORUS I/O parameter determines whether the chorus circuit is active or bypassed for the current
preset. Select IN to engage the chorus circuit. Select OUT to bypass the chorus circuit.
The CHORUS OUTPUT 1 parameter determines the volume of Voice 1.
This parameter allows you to pan Voice 1 to the left or right channel.
The CHORUS DEPTH 1 parameter adjusts the amount of modulation of the Voice 1 signal. A lower depth
setting will produce a more subtle detune effect, while a higher setting results in a more extreme detuning of
Voice 1.
The CHORUS RATE 1 parameter determines the sweep speed (or the speed at which Voice 1 is modulated).
This parameter allows you to select the minimum delay time (in milliseconds) for Voice 1. This delayed
signal (along with Voice 2) is detuned and modulated to produce the chorus effect. Using shorter delay times
will result in a tighter sounding chorused signal, while longer delay times will produce a larger ambient
effect.
The TIME 1 parameter determines the multiplier by which a new modulation rate will be selected for the
RATE 1 parameter when the Tap Delay feature of the Blue Thunder is used. (See Section 7 page 42: "Tap
Delay" for more information on the Tap Delay feature.)
The CHORUS OUTPUT 2 parameter determines the volume of Voice 2.
This parameter allows you to pan Voice 2 to the left or right channel.
The CHORUS DEPTH 2 parameter adjusts the amount of modulation of the Voice 2 signal. A lower depth
setting will produce a more subtle detune effect, while a higher setting will produce a more extreme detuning
of Voice 2.
The CHORUS RATE 2 parameter determines the sweep speed (or the speed at which Voice 2 is modulated).
This parameter allows you to select the minimum delay time (in milliseconds) for Voice 2. This delayed
signal (along with Voice 1) is detuned and modulated to produce the chorus effect. Using shorter delay times
will result in a tighter sounding chorused signal, while longer delay times will produce a larger ambient
effect.
The TIME 2 parameter determines the multiplier by which a new modulation rate will be selected for the
RATE 2 parameter when the Tap Delay feature of the Blue Thunder is used. (See Section 7 page 42: "Tap
Delay" for more information on the Tap Delay feature.)
