Rocktron Xpression - Manual (Page 32)

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.
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:

PHASER I/O
PSR PAN
PSR DEPTH
RATE
P>RESONANCE
PSR STAGES
TIME
PHASER LVL
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 pronounced 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 Xpression is used. (See Section 7 page 50: "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 Xpression relative to the direct signal
and other effect signals. A setting of “0” (zero) will set the phaser level
at unity gain.
