Micrón (v.) ASSEMBLY MANUAL Thank you for choosing this kit. Let s go! WARNING: Please, read the instructions completely before start and follow the steps carefully. Some of assembly parts are not so obvious as they seem even for the expert DiYers. MAIN PCB ) Solder the resistors according to their value.

Take your time. The components must be in the PCB and attached to the board prior to soldering, otherwise it will be very difficult (even impossible) to place the front panel. Besides, it will cause mechanic stress that will shorten the lifetime of the component or the soldering or even it could break it. ) Screw spacers first One of the pot. have a different value. (05) See the bottom pot. ) Without soldering, place the potentiometers, jacks, switch and leds (long led on +), the green led goes to the EG, next to the jack gate. The red led goes next to the pote Drive. All pots 0 (00k) except Release pot (rel) =05 (M) ) Place the panel and screw the potentiometers, jacks, switch and put the leds in his place, now it s time to solder all. ) Put the knobs in their place and it s ready.

CALIBRATION After the assembly it s necessary to do some calibrations. Handle the trimmers multiturn with care. It s not a potentiometer as those of the panel. If you turn it and nothing happens, maybe it's the limit (there is no block). ) Adjust the start point of the VCA: When the module is connected to the power bus, by default, you will have signal in the out. (Wave selector in saw or pwn and open the filter.) The gate led must be ON constantly. Now, connect a jack without signal to the gate. Gate led OFF. When connecting the jack, if Micrón stops sounding, then it is ok. In order to increase precision, move the INIT Trimmer just to the point prior it starts sounding. After connecting the jack, if it continues sounding, adjust INIT until it stops sounding. ) Adjust the VCO: Tools: -Small flatheaded screwdriver, -Tuner, -Tester/multimeter, -source or module that can produce constant voltage (cv) of.000v. (for example: Befaco atenuverter...) Calibration steps: -Next to the jack v/o there is a PAD (with a hole). The tester measurement should be 5.00v, otherwise, adjust using the REF. trimmer beside. See photo-------------------------> -Locate the trimmers MIN and V/O under the jack sync. -Connect a tuner to the micrón -Center the pote tune. 5-Make ready an out of another module of.000v with the multimeter/tester. -With the tuner, adjust a C (5.Hz) with the trimmer MIN. 7-Now, put those.000v to v/o and adjust again with the trimmer MIN but this time to C5 (5.5Hz ) 8-Remove the.000v now. If the tuner indicates C you have finshes! Otherwise: 9-Adjust a C with the trimmer V/O and go back to the step 7). It s quite normal to do the 7, 8 and 9 steps more than once. But if you have done it more than 0 times, make sure you do the steps correctly, or /and take a rest and try it again later. If you cannot do it in another 0 times, you should check that you have soldered all the components in their correct place, value and polarity. In my web, you will find tutorial videos. 0- Once it indicates C without the.000v and C5 with the.000v, (0v=C and.000v=c5), you can check with 5.000v it should get C7. Otherwise, do the following: - Adjust until C7 with the trimm EXP, next to the Jack FM. Then, remove the 5.000v. If it indicates C go back to the step 7). If it doesn t go back to the step 9). Do the loop 7, 8 and 9 another time, until it's C and C5. Afterwards, put 5.000v and check that there is C7. Otherwise, start again with step 0 Now the Micrón is ready to be used. Enjoy it!!
