Demo units have been used in the field and at trade shows. They typically have minor cosmetic defects only, such as dents, scratches, painting errors, and misprints which do not affect the sound quality and usability of the product. Demo purchases come with a 1-year limited warranty.

The PPC-125 Matched Pair are transformer-less electret condenser microphones designed for pro and semi-pro recording applications as well as sound reinforcement. The capsule is a 25mm unidirectional electret. The 25mm capsule was chosen for its warm tone similar to a large-diaphragm vocal microphone and its extended highs for the natural reproduction of acoustic instruments. The microphone is designed, built, and tested in Nashville TN. Each capsule is tested and selected for its sensitivity and uniform frequency response. The final microphone is tested as well against a calibrated laboratory standard instrumentation microphone to ensure the uniform response and sensitivity of each microphone.
 
The electronic circuit is a proprietary topology developed for Teegarden Audio by veteran designer Stephen Mills known as Pure Path Condenser “PPC”. PPC technology provides the cleanest path from the capsule to the output without coloration. The housing design allows for a greater open area to the rear of the capsule compared to other microphones in this class. This allows for a uniform off-axis response which translates into a smooth sound and lower feedback due to sharp high-frequency peaks. The housing is manufactured in the USA.
 
The screen material in the housing has been tested and chosen for its shielding properties and transparency in the audio frequency range 20-20kHz.
 
Teegarden Audio is committed to offering high precision, high-quality professional microphones designed, tested, and built in the USA for a competitive price to the audio community.
