TC electronic SDN BHD NM-1 Flanger, +VARIATION Button, Normal or TZF Through Zero Flange mode

EFFECT TYPES: CHORUS

+VARIATION Button

Two phase settings are available for the Tri-Chorus. One option produces a more traditional Chorus sound where the phases of the three Choruses are tilted by 90, 180 and 270 degrees respectively. The other option is an asymmetric type where the phase and depth parameters are tuned to produce a wilder and more “uncontrolled” Chorus effect.

Flanger

Introduction

The Flanger belongs to the same “family” of modulation effects as the Chorus effect. The signal is split, and one of the signals is pitch modulated.

The characteristic “flanging” sound occurs when the pitch-modulated part of the signal is slightly delayed and fed back to the input of the effect algorithm. In a Flanger effect, the delay times of the modulated signal are typically shorter compared to a Chorus effect. Experiment with the Feedback parameter to get an idea of the effects you can achieve.

Normal or TZF (Through Zero Flange) mode

Two Flanger modes are available. To select the Flanger, press the EFFECT button repeatedly. The LED will turn red, indicating Normal mode. Press the EFFECT button once more, and the LED will turn green, indicating TZF mode. The TZF mode emulates the original way of creating a flange effect, with two identical pieces of audio material being played back simultaneously on two tape decks and then being mixed on a third deck. The flanging effect was achieved by slowing down and speeding up the two decks at different times. An essential part of the special effect created this way is the unique phase cancellation occurring when the two signals pass each other in time (the zero point). A conventional Flanger pedal/ algorithm tries to emulate this effect, but because the two signals will never cross each other in time, until now, phase cancellation wasn’t possible.

But with the NOVA Modulator’s TZF mode, it is.

DEPTH Knob

Use the DEPTH knob to set the intensity of the effect. The more you turn the knob clock-wise, the more “out of tune” the modulated part of the signal is.
