Pop Filters Pop filters or pop screens are used in controlled studio environments to minimize plosives when recording.
TRS (Tip, Ring, Sleeve) Connectors A phone connector (TRS) also called an audio jack, phone plug, jack plug, stereo plug, mini-jack, or mini-stereo. 2.5 mm mono (TS), 3.5 mm mono (TS) and stereo (TRS) phone connectors, as well as 6.35 mm (1⁄4 in) (TRS) phone connectors
TRS Audio Connector 1. Sleeve: usually ground 2. Ring: Right-hand channel for stereo signals, negative polarity for balanced mono signals, power supply for power-using mono signal sources 3. Tip: Left-hand channel for stereo signals, positive polarity for balanced mono signals, signal line for unbalanced mono signals 4. Insulating rings
