U-036 4ch audio-to-trig (4HP)

4ch audio-to-trig converter with adjustable trig time and rest time for making Eurorack-level trigs from audio signals (for example from individual outs from drummachines or similar sources)

From top:
four input jacks (low level external audio up to eurorack level)
four output jacks + LEDs (fixed 5V trigs/gates)

There are internal trimmers for setting trig time and rest time (1ms-500ms). Each input can be AC or DC coupled (set jumper behind input jack for DC coupling) and contains preamp with adjustable amplification (0dB to +26dB, internal trimmer). Output triggers are fixed level (5V) and length can be set by „trig time“ knob. Trig time is counted from first rising edge of incomming audio signal (mode jumper set) or from end of incomming signal (mode jumper removed). This allows fixed length trigs or changing trig length using input signals with different length. „Rest time“ knob disables retriggering for set time (avoiding false/unwanted triggers).

Some input trigs can be skipped if sum of trig time and rest time is greater than input spacing – module can work as “clock divider”

Width: 4TE/ 4HP/ 20mm
Depth: 55mm /2,2″ max.
Current: 20mA
Power cable included

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
