DE-1 Owner’s Manual

FLANGE

FLANGE 1 (Stereo Duo Flange)		(E)	Dual stereo flanger that preserves the L-R input balance. Two flangers
			with different modulation phase are applied. Since the rate is quite slow,
			this is effective when applied to a beat track.
FLANGE 2 (St Hi-Rate Duo Flange 1)		(E)	Dual stereo flanger that preserves the L-R input balance. Two flangers
			with different modulation phase are applied. The rate is fairly fast.
FLANGE 3 (St Hi-Rate Duo Flange 2)		(E)	FLANGE 2 with lighter feedback. Dual stereo flanging.
FLANGE 4 (Stereo Solo Flange 1)		(E)	Single stereo flanging that preserves the L-R input balance. Deep
			feedback.
FLANGE 5 (Stereo Solo Flange 2)		(E)	FLANGE 4 with lighter feedback. Single stereo flanging.
FLANGE 6	(Stereo Duo Flange + Hall)	(C)	Dual flanging + hall reverb
FLANGE 7	(Stereo Duo Flange + Plate)	(C)	Dual flanging + crisp plate reverb
FLANGE 8	(Stereo Duo Flange + Wet Plate)	(C)	Dual flanging + gentle plate reverb
FLANGE 9	(Stereo Solo Flange + Hall)	(C)	Single flanging + hall reverb
FLANGE 10 (Stereo Solo Flange + Plate)		(C)	Single flanging + crisp plate reverb
FLANGE 11 (Stereo Solo Flange + Wet Plate)		(C)	Single flanging + gentle plate reverb

*ADJUST knob 1 (PARAM.1): Rate (adjust the modulation speed of the flanger)

*ADJUST knob 2 (PARAM.2): Feedback Level (adjust the resonance of the flanger)

*ADJUST knob 3 (PARAM.3): Reverb Time (adjust the length of the reverberation)
