It's time to set the bias, so please turn to "SETTING THE BIAS" on page 30. Once the bias is set,
your Cortado is complete, and ready to install inside your shielding container. This can be made of
anything that conducts electricity. You must connect the grounding wire to the container itself; the PCB
must NOT touch the container. If necessary, insulate it with electrical tape, or mount it with the standoff
provided.
INSTRUMENT PICKUP
To permanently install your Cortado inside a musical instrument, or a non-metallic sculpture or art
installation, you may use the copper tape instead of the metal can to shield the PCB. This will keep the
over-all size of the Cortado small and easy to tuck inside a sound hole or instrument body. Unscrew
the standoff from the PCB.
1. Solder the XLR cable to the PCB (86). The red wire goes to the hole labeled XLR3. The white wire
goes to XLR2. The copper shield wire goes to XLR1 (88).

2. Solder the piezo disc cable to the PCB. The red wire goes PZ1. The white wire goes to PZ2.
Solder the shield of the cable to ground: use a pad in one of the corners of the PCB. Use
whichever is closest (87,88).

3. At this point take a break from assembly, and set the bias by following the steps in the section
"SETTING THE BIAS" on page 30. After the bias is set, continue on from here to the end of
the section.
