  • Page 8 STEP 1: Add the resistors . Resistors are not polarized, so it does not matter which end goes in which solder pad. Take your time and be sure not to confuse similarly banded resistors such as the 470k with the 4k7 or the 22k with the 2k2. If you have difficulty reading the color bands, use a digital multimeter to test the value of each resistor.
  • Page 9 STEP 2: Add the diodes. For the 1N4148 and 1N4001 diodes, be sure to match the end of the diode with the stripe to the layout on the PCB. The stripped end should go in the square solder pad. The smaller unlabelled diode spaces are for the 1N4148 diodes.
  • Page 10 Step 3: Add the IC sockets. Just the sockets!!!! Do not add or solder the actual ICs themselves yet. The ICs never get soldered. Only the sockets get soldered. You will install the actual ICs at the very end of this build. The sockets have a U-shaped notch on one end.
  • Page 11 Step 4: Add the film capacitor. These are not polarized and can be inserted into the PCB either way. Note: The 4.7u capacitor highlighed in yellow is not a film cap and should not be added at this time. It is an electrolytic cap and will be added when you add the other electrolytic caps.
  • Page 12 Step 5: Add the Transistors. Orient the transistors so that the flat side of the tansistor body matches up with the flat side on the PCB layout. There are 5 different transistors in this build and it is very important that they each go in their correct place. Be sure to take the time to differentiate the different transistors.
  • Page 13 STEP 6: Add the aluminum electrolytic capacitors. These are polarized. The positive end will have a longer lead and should go in the square solder pad. The negative end will have a shorter lead with a black or white stripe running down the body of the capacitor. Note: The space for the 4.7uf capacitor (highlighted in yellow) is not round, but should be treated just the same as the other electrolytic caps.
  • Page 14 Step 7: Add wires to the IN, OUT, AUX, , and three Ground eyelets. Start by cutting six 2.5 pieces of wire and two 1.5 piece of wire. Strip 1/4 off each end and tin the ends. Tinning means to apply some solder to the stripped ends of the wires. This keeps the strands from fraying and primes the wire for soldering.

  • Page 15: Main Pcb Assembly

    Main PCB Assembly Below is a picture of an internal nut DC adapter jack with nylon nut. Your kit may come with a jack that looks like this, or it may come with an external nut jack with metal nut. Both have the exact same termination and both function identically. Internal nut jacks mount to the enclosure from the outside and the nut goes on the inside.
  • Page 16 Step 2: Connect the TIP (negative) terminal of the DC adapter jack to the eyelet on the PCB with 2 inches of hook up wire. Connect the SLEEVE of the DC adaptor jack to eyelet on the far right side of the PCB with 2 inches of hook up wire. Connect the battery disconnect terminal of the DC adaptor jack to the eyelet more towards the center of the PCB with 2 of hookup wire.
  • Page 17 Step 3: Flip the PCB over so that the bottom or solder side is up. Insert the B10k(TONE), B50k(MIX) potentiometers, the two SPDT Toggle Switches, and the two LEDs into the bottom side of the PCB. DO NOT SOLDER ANYTHING YET!!! The LEDs will have one lead that is longer than the other.
  • Page 18 Step 4: Hold the PCB in one hand so that the component side of the PCB is in the palm of your hand and the bottom side with the pots, toggle switch and LED is facing up. Now use your other hand to guide the predrilled enclosure onto the PCB assembly so that the pots and LED all go into their respective holes.

  • Page 19: Wiring

    Wiring Step 1: Install the 1/4 jacks to the enclosure. The Divided Octave only uses mono jacks. Be sure to install the jacks so that the prong of the IN JACK is at 12 o'clock and the prongs of the OUT and AUX JACKS are are both at 4 o'clock.
  • Page 20 They are both 180 degrees of each other. Either way is fine. It does not matter as long as the flat sides of the solder lugs are running vertical, not horizontal. Yes, this is different from all other BYOC kits, but the number designators are still exactly the same...
  • Page 21 Step 3: Connect the pre stripped and tinned wires to the 1/4 jacks. Step 4: Cut, strip, and tin the footswitch wires. · Cut 7 x 3/4 pieces of wire. Strip 1/8 off each end and tin. These will be used to connect lugs/eyelets 7, 8, &...
  • Page 22 PCB. Insert the wires into the top side of the PCB and solder on the bottom side. Step 8: Return the PCB Assembly back into the enclosure. Congratulations! You are now finished building your Divided Octave kit. You just need to install the IC's into their sockets.

  • Page 24: Operation Overview

    Operating Overview MIX: Blends the Octave down and Ringer with clean signal. Full-turn clockwise is pure clean signal. Full-turn counter-clockwise is pure octave signal. TONE: Controls the amount of high frequencies cut from the octave down signal. RINGER: Activates a Green Ringer circuit for an added octave up. STABILIZE: Improves the octave tracking for some instruments.
