Bastl Instruments Ciao!! is a compact, performance-oriented Eurorack output module, built with high-quality, low-noise components and a layout designed to achieve the best possible conversion from modular to line level. In just 5 HP, it offers two stereo line outputs, a headphone amplifier, and some clever solutions for signal distribution—ideal for connecting your modular system to recorders, audio interfaces, and sound systems.

Modular-to-line-level conversion for clean recordings

Stereo pairs A and B each have a dedicated level control, with signal indication and a warning for potential clipping on the line input to which you’re sending the signal. Channel A features balanced 6.3 mm jack outputs to minimize noise and ensure the highest quality signal to your audio system.

Channel B and Dedicated Headphone Output

Channel B outputs to a 3.5 mm stereo jack, which can also serve as an additional headphone output. The dedicated headphone output offers high power and includes a selector switch to listen to either Channel A or Channel B.

Intelligent Signal Distribution and MIX Switch

Input normalization makes it easy to route signals to some or all outputs. The MIX switch blends Channel B into Channel A in stereo, opening up the module to various useful live scenarios, such as monitoring or a simple stereo mix. A jumper on the back panel allows you to customize the normalization path.
