102 Minimum Theremin Kit Products Specifications

(Back to "Technical Information")



 All components furnished in Minimum Theremin 102 Kit Products and factory-assembled versions are RoHS compliant or compliant by exemption, and applicable for export to all markets requiring RoHS compliance.

The populated printed circuit board is furnished with a two trimmer potentiometers. 

Trimmer potentiometer RV1, "BIAS ADJ," is user-calibrated to obtain the specified tone frequency range.

Trimmer potentiometer RV2, "ZERO CAL," is user-calibrated to obtain the specified relationship of hand distance and tone frequency.

The calibration procedure for the trimmer potentiometers is described in the 102 Minimum Theremin Kit Assembly Instructions.

To ensure proper calibration, this product should be used with the 102-ANT antenna assembly.
