A-138f Dual 3-Way Crossfader

Doepfer's dual three-way crossfader in 4 HP: two identical crossfaders, each blending three inputs into one output.

Key features

• Two identical crossfaders, each with inputs A, B and C, one output and one knob
• Knob fully counter-clockwise: only A at the output; centre: only B; fully clockwise: only C
• In between, a mix of A and B (left half) or of B and C (right half)
• DC coupled: for audio and control voltages alike
• Uses: morphing between VCO waveforms, between the outputs of a multimode filter, or between envelope, LFO and random voltages
