	RP21D User’s Guide	Section Two - Editing Functions
Out A - B	Adjusts the overall level of flange voice A or B. Ranges from Off to 100%.
Pan A - B	Controls the stereo soundfield placement of flange voice A or B. Ranges from -99 to 99.
Out L - R	Controls the output level of the left or right side of the flanger. Ranges from Off to 100%.

Phasers

The Phaser or “Phase Shifter” as it is sometimes called, is a classic effect from the 70's that uses phase cancellation to create a warm sweeping effect. The effect is created by making a copy of a signal and moving it in and out of phase while mixing it with the original signal. As it moves, different frequencies are cancelled out creating a smooth curling sound. There is also a feedback control that sends the shifting signal back into the phaser's input. This intensifies the sound even more.

When do I use a Phaser? A great example of this can be heard most when you listen to music of the 70’s. Guitarist of the day loved their Phasers. A Phaser is a great effect to use when playing clean and funky rhythms.

Phaser Parameters:
Dry: Lvl	Controls the level of the dry (uneffected) signal. Ranges from Off to 100%.
Balance	Controls the positioning of the dry signal in the stereo soundfield. Ranges from -99 (all left) to 99 (all right).
Speed	Controls the Low Frequency Oscillator (LFO) speed of the phaser. Ranges from 0.06 to 16.0 Hz.
Depth	Controls the intensity of the phaser effect. High settings of DEPTH combined with high settings of FDBCK produce
	dramatic, synth-like textures. Ranges from 0 to 30 milliseconds.
FdBck	Controls how much of the flanged signal is fed back to the input of the Module. The FDBACK Parameter is what gives
	phasers their distinctive resonating sound. Ranges from -99% to 99%.
WvFrm	Selects which waveform the LFO follows. Options for this control include sine, triangle, SP1 (Special 1), and SP2
	(Special 2). The sine wave setting is probably the most easily recognized, but the smooth response of the triangle
	wave or the intensity of SP1 or SP2 typically produce better results. See figure 4-2.
Out A - B	Adjusts the overall level of phaser voice A or B. Ranges from Off to 100%.
Pan A - B	Controls the stereo soundfield placement of phaser voice A or B. Ranges from -99 to 99.
Out L - R	Controls the output level of the left or right side of the flanger. Ranges from Off to 100%.

Pedal Phaser

The Pedal phaser is a phaser that can be controlled by an expression pedal to control the depth and feedback of the effect

Pedal Phaser Parameters

FX and Dry Level Controls the FX and Dry level of the Pedal Phaser module. Ranges from Off to 100%.

Balance	Sets the Balance of the effect. Ranges from L 100 to R 100.
Pedal	This parameter is used to be controlled by the expression pedal to control Depth and Feedback. Range: 0 to 100.
