XAOC Praga
Four-channel voltage controlled mixer for Eurorack
Praga is an expandable four-channel voltage controlled mixer featuring a stereo mixing bus, two auxiliary sends with stereo returns, clickless muting, dedicated modes for unipolar and bipolar voltage control over volume, DC-coupling, and a super-clean signal path obtained via high-quality VCA and opamp chips.
XAOC have carefully crafted Praga’s voltage control response to achieve what they believe to be the optimal user experience found in an eurorack mixer. The design features an elaborate control circuit that combines the internal voltages generated by the panel potentiometers with external CV over volume and pan. The result is a natural attenuator response that constrains VCA gain to a usable range while minimising distortion.
Features
- Intuitive volume control behaviour
- Voltage control over volume and pan
- Dedicated modes for unipolar and bipolar voltage control over volume
- DC-coupled signal path
- Channel level indicators
- Two auxiliary sends with stereo returns
- Clickless channel muting
Expandability
- Expandable by daisy-chaining more units
- A dedicated Hrad expander module is planned
XAOC Hrad
Mixing Console Commander Eurorack Module
Hrad is an expander for the Praga four–channel stereo mixer that adds new functionality and enhancements. Hrad features a master section with stereo volume control over the overall mix with five-bar LED stereo level indicator, a stereo sum output that is switchable between eurorack and line level, a headphone output with volume control that is independent of the main attenuator, a special cue input that can be auditioned with and without the mix, four control inputs for automated muting/unmuting of individual channels, four inputs for voltage control over the aux send levels, four insert points in the aux sends, and two stereo attenuators for Praga’s two AUX return pairs.
