The Teegarden Audio PPC-125 Microphones are a matched pair of 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 insure uniform response and sensitivity of each microphone.

The electronic circuit is a proprietary topology developed by Stephen know as Pure Path Condenser “PPC”. PPC technology provides the cleanest path from the capsule to the output without coloration. (see PPC Tech) 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 screen material in the housing has been tested and chosen for its shielding properties and transparency in the audio frequency range 20-20kHz. The housing is manufactured in Indiana at the HiPoint Machine shop. HiPoint manufactured many microphone components for Harman Pro (Crown, AKG, JBL) in the 90s and 2000s that are still offered by AKG. They also manufacture precision components for the medical industry.

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
