No description available.


The preamplifier circuit created was composed as a stand-alone compact unit, helpful to control the signals produced by guitar pick-ups, especially the contact "bug" types applied to acoustic instruments. Clearly, it can be utilized with any sort of instrument and pick-up. It features a -10dB, 0dB and +10dB pre-set input selector to modify input sensitivity utilizing TE's 1969507-2 FAST FLG RCPT HSG NAT, and to adapt to any pick-up type and model.

The UIC1 Op-Amp is wired as an inverting amplifier, having its gain set by a three ways switch inserting different value resistors in parallel to R4. In the input stage, the signal starts from TE's 1969507-2 FAST FLG RCPT HSG NAT followed by an active three-band tone control stage having unity gain when controls are set in their center position and built around UIC2.

Speed of application, uniform reliability and low per-line cost are the advantages of TE's FASTON products, which made them the industry leader in the appliance and automotive industries. A complete line of application tooling has been developed specifically for these terminals. Crimping dimensions for each terminal are precisely controlled so all connections are identical in performance. With over 50 years of experience providing quick connects to the customers, TE is constantly striving to introduce new and improved products to add to our quick connect family. It is their commitment to innovation and continuous improvement that allows the FASTON terminal product line to remain the leader in the industry.



I hope no one try's to build this as drawn; the opamps need to be flipped vertically (the inputs are backwards).

Hi mtripoli3! We have already made the correction regarding the opamps. Thank you for your keen observation and for viewing TE projects. God Bless.
