2-channel stereo crossfader

6 HP Eurorack module

A two-channel stereo crossfader for DJ-style Eurorack mixing and jamming, with voltage control and cue monitoring.

Features

• Mixes two mono or stereo input pairs to a stereo output with manual or voltage control.
• Provides pre-mix cue monitoring for either input pair.
• DC coupling supports use with audio or CV, including stereo VCA and mix-processing duties.
• Equal-power crossfading gives smooth, constant-level blending between sources.

Controls & Jacks (14)

• Main Output Left— Left channel of the main stereo crossfader output.
• Main Output Right— Right channel of the main stereo crossfader output.
• Cue B— Latching illuminated button that routes input B to the pre-crossfader Cue Output; its illumination indicates that B is cued.
• Input A Left— Left-channel input for stereo input A; normalled to Input A Right for mono signals and DC-coupled for audio or CV.
• Cue A— Latching illuminated button that routes input A to the pre-crossfader Cue Output; its illumination indicates that A is cued.
• Cue Output Right— Right channel of the pre-crossfader stereo cue output for headphone monitoring.
• Input B Right— Right-channel input for stereo input B; receives the normalled left signal when Input B Left alone is patched.
• Cue Output Left— Left channel of the pre-crossfader stereo cue output for headphone monitoring.
• Input A Right— Right-channel input for stereo input A; receives the normalled left signal when Input A Left alone is patched.
• Crossfade— Sets the manual crossfader offset, blending stereo input A and B; it offsets incoming Crossfade CV.
• Input B Left— Left-channel input for stereo input B; normalled to Input B Right for mono signals and DC-coupled for audio or CV.
• Cue B Indicator— Lights when stereo input B is routed to the pre-crossfader Cue Output.
• Crossfade CV Input— Bipolar -5 V to +5 V control-voltage input for the stereo crossfade; the Crossfade control provides its offset.
• Cue A Indicator— Lights when stereo input A is routed to the pre-crossfader Cue Output.
