Make Noise Rosie
Live performance output with crossfader, FX loop, and Auto-CUE
8 HP Eurorack module
Rosie is a performance-oriented output interface module for Eurorack systems featuring a crossfader between two mono channels, a mono FX send with stereo FX return loop, and an Auto-CUE headphone monitoring system. It is designed for live modular performance, allowing the performer to privately preview and prepare the next patch in headphones while the audience hears the current patch through the line output. Rosie handles signal level translation from modular levels to line level, making it suitable for PA systems, mixers, recording interfaces, and headphone monitoring.
Features
- Two AC-coupled mono signal inputs (Channel A and Channel B) accepting typical 10Vpp modular audio
- LED signal strength indicators for Channel A and Channel B
- Manual crossfader for blending between Channel A and Channel B
- Auto-CUE system automatically routes the non-selected channel to the CUE output for private headphone monitoring
- Mono FX Send output at unity modular level (approx 10Vpp) for patching into modular effects processing
- Stereo FX Return with independent Return Level control (0% to 120% range)
- FX Return can be used as a third mixer input (mono or stereo) when no FX Send is used
- Master Level control with soft limiting and OVL overload LED indicator
- Master Line Output on 1/4 inch TRS jack wired as stereo with low output impedance (60 ohms) suitable for headphones and long cable runs
- CUE Output on TRS Mini-Jack wired as mono with low output impedance (30 ohms) suitable for headphones and line level inputs
- Independent CUE Level control
- Burr Brown line drivers on both CUE and Master outputs
Controls & Jacks (15)
- Return Level — Manually operated panel control to set the level of the FX Loop Return in the Master Output. Range 0% to 120%.
- CUE Output — TRS mini-jack wired as mono. Low output impedance (30 ohms) allows driving headphones or line-level inputs. Auto-cues the opposite channel f
- Crossfader — Selects between Channel A and B or some combination of A and B to be sent to FX Send and Master Line Output. Fully counter-clockwise selects
- Master Level — Sets the volume of the Master Line Output with limiting and overload indication.
- FX Send — Mono 10Vpp audio signal intended to be patched into the modular system. Same signal as Master Line Output but at typical modular level.
- Master Line Output — 1/4" TRS jack wired as stereo output. Low output impedance (60 ohms) allows driving headphones or line-level inputs. Output around 2Vpp with
- FX Return M — Mono FX Loop return (use only this jack for mono operation). Expects typical 10Vpp audio signal. AC coupled.
- Channel A Signal Input — Expects typical 10Vpp audio signal from modular system. AC coupled.
- Channel B Signal Input — Expects typical 10Vpp audio signal from modular system. AC coupled.
- CUE Level — Sets volume of the signal for CUE Headphones Output.
- Channel A Level Indicator — LED lights to show strength of signal patched to Channel A input.
- Main — Indicates module power status.
- Channel B Level Indicator — LED lights to show strength of signal patched to Channel B input.
- Overload Indicator — OVL LED lights when signal level is too high.
- FX Return ST — Stereo FX Loop return right channel (use both mono and stereo jacks for stereo operation). Expects typical 10Vpp audio signal. AC coupled.
