PIEZO DISC
From this point onward, sections of the manual are specific
to your application.
The piezo disc and its connection to the circuit must be
carefully shielded. The procedure is the same for the
Standard Contact Mic and the Instrument Pickup: you
attach the piezo to the remaining piece of mic cable, then
wrap the piezo in electrical tape, and then copper tape.
You can also provide shielding by installing the whole
Cortado into a grounded, conductive enclosure, as with
the Tin Can Mic. In this case you attach the piezo to a fine
wire, with no further shielding.
Now drop down to the section appropriate to your project.
STANDARD CONTACT MIC &
INSTRUMENT PICKUP
Follow this section to prepare the piezo for use with either the Standard Contact Mic or Instrument
Pickup.
1. Solder the 18" (45cm) microphone cable to the Piezo disc (Part #TD-10-22): For your
convenience, we have tinned the disc to make soldering easier.
a. Solder the white wire to the ceramic part of the piezo disc (40).

The best way
to successfully solder wires to
the disc is to lay the tinned wire
on top of the tinned part of the
disc and very quickly touch them
together with the soldering iron.
