Rocktron Blue Thunder, User Manual

Page: 27 / 64

Phase shifting involves splitting the input signal into two signals, then
shifting the phase of different frequencies of one signal before mixing it back
with the original signal.
To access this function you must first press the “EDIT” button to enter into the
“EDIT MODE” and turn the FUNCTION SELECT control to the right until
***PHASER*** appears on the display.
The PARAMETER SELECT control will allow you to access each of the following
Phaser parameters.
The PARAMETER ADJUST control allows you to adjust the selected parameter:

The PHASER I/O parameter determines whether the phase shift circuit is active or bypassed for the
current preset. Select IN to active the phaser. Select OUT to bypass the phaser circuit.
The PHASER PAN parameter allows you to pan the phase shifted signal to the left or right channel
by any amount.
The PHASER DEPTH parameter determines the modulation depth of the phase shift effect. Higher
parameter settings result in the sweep of the filtering effect occurring over a wider frequency range.
The RATE parameter determines the speed at which the phase shifted signal is modulated.
The PHASER RESONANCE parameter adds feedback to the Phaser so that it has a more pro-
nounced effect.
The PHASER STAGES parameter determines how many stages of phase shift are to be active. A
parameter setting of "4" produces a result similar to a vintage Phase 90, while a setting of "6"
emulates other common phaser pedals.
The TIME parameter determines the multiplier by which a new modulation rate will be selected for
the RATE 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 PHASER LEVEL parameter allows you to control the level of the phaser signal at the output of
the Blue Thunder relative to the direct signal and other effect signals. A setting of “0” (zero) will set
the phaser level at unity gain.
