Bastl Instruments Ciao!! Modular System

Bastl Instruments Ciao!!: Flexible Output Solution for Modern Modular Setups

The Bastl Instruments Ciao!! introduces professional modular-to-line level conversion to Eurorack, packing four high-quality line outputs and a robust headphone amplifier into a compact 5 HP module. Low-noise components have been carefully selected to ensure clean signal transfer, whether you're recording or performing live. Not just another output module, Ciao!! offers a user-friendly layout and advanced features tailored for critical monitoring and creative routing. Many modular artists will find this model indispensable for achieving precise and adaptable output control.

What Makes Ciao!! Unique Among Output Modules

Features like advanced normalization, independent signal indication with clip detection, and stereo mixing set Ciao!! apart from standard output modules. Balanced 6.3 mm outputs on Channel A reduce noise for clean professional connections, while the dedicated headphone amp—with channel selection and a mix switch—caters to complex monitoring needs in any environment.

Dual Stereo Channels for Versatile Signal Management

Routing multiple audio paths is simplified with intuitive normalization and level control. Precise gain staging is made possible by independent level knobs and visual indicators, so you can dial in the perfect balance. Flexible output configurations work with virtually any workflow.

• Channel A Output: 6.3 mm balanced jacks — ensures low-noise, high-fidelity connections to mixers or speakers
• With the Channel B output on a 3.5 mm stereo jack, you get both stereo out and a convenient extra headphone send—perfect for personal monitoring.
• Dedicated Level Controls: independent volume for each stereo pair, allowing nuanced mixing and monitoring

Comprehensive Monitoring and Mixing Tools

With advanced monitoring and pre-listening features, Ciao!! adapts to both solo and collaborative setups. The mix switch and normalization provide creative options for stereo mixing or parallel signal processing, while the headphone amp supplies strong output with channel selection for detailed monitoring.

• Headphone Output: Supports 8–250 Ω headphones — delivers clear, powerful sound for any monitoring scenario
• Signal Indication: per-channel LED with line-level clipping warning, so you can avoid downstream distortion
• By blending Channel B into A, the mix switch enables flexible setups for FX returns or previewing signals before they hit the main mix.

Technical Excellence in a Compact Package

Despite its small footprint, this model is built for reliability and adaptability. The robust construction and smart power protection make it suitable for demanding professional environments. Use it to bridge modular synths and pro audio gear with ease.

• Module Width: 5 HP — fits easily in most Eurorack cases
• Its shallow depth of 29 mm (with power cable connected) means it fits skiffs and portable racks without issue.
• Current Draw: <120 mA (w/o headphones), <190 mA (max headphones) — efficient power usage for complex setups
• Input Impedance: 100 kΩ, Output Impedance: 220 Ω

Who Will Benefit from the Ciao!! Module?

Producers, live performers, and educators seeking precise modular output management will appreciate the flexibility here. Advanced users can create quadraphonic or multi-zone setups, while newcomers benefit from the clear interface and strong monitoring. Whether in the studio or on stage, the YRS-23 brings high-quality output, flexible monitoring, and seamless integration for modern modular artists.
