Frequently Asked Questions - Drezno Xaoc
What is the Xaoc Drezno?
The Xaoc Drezno is a Eurorack module that converts analog signals to 8-bit digital data and vice versa. It can also be used as a binary logic processor, oscillator, or envelope generator.
How do I power the Drezno?
Connect the included 10-pin ribbon cable to your Eurorack case's busboard, ensuring the red stripe aligns with the -12V marking on the module and case.
What are the main modes of operation?
The Drezno has four modes selectable via toggle switches: ADC/DAC (analog conversion), Logic (binary operations), Clock (clock division), and Quantizer (pitch quantization).
How do I use the Drezno as an oscillator?
In DAC mode, patch a digital pattern (e.g., from a sequencer) into the bit inputs, and the Drezno outputs a corresponding analog waveform at the analog output.
Can I process CV signals?
Yes, the Drezno can process control voltage signals up to ±10V. Use the gain potentiometer to adjust the input range.
What is the clock input for?
The clock input synchronizes the Drezno's internal operations (e.g., bit shifting, sampling) to an external tempo or gate signal.
How do I reset all bits to zero?
Toggle the Reset switch (if available) or send a gate signal to the reset input. Alternatively, power cycle the module.
What kind of cables do I need?
Use standard 3.5mm mono TS patch cables for all analog and digital connections.
How do I clean the module?
Unplug the module and use a dry or slightly damp cloth. For contacts, use isopropyl alcohol and a lint-free swab.
Where can I find firmware updates?
Visit the Xaoc Devices website or check your retailer. The Drezno firmware can be updated via the USB port (if supported) or manually.
