The Polsen MO-IDL1 is a lavalier condenser microphone with a DSLR/smartphone switch designed to deliver accurate speech capture for podcasting, vlogging, video and television production, interviews, and public address. Its electret condenser element produces a 20 Hz to 20 kHz frequency response, which is honed to complement the sound of the human voice. The omnidirectional polar pattern ensures responsive sound pick-up from all directions and avoid the bass boost caused by proximity effect. An in-line switch enables the MO-IDL1 to be easily compatible with DSLRs, camcorders, PCs, and mobile devices. Affix the supplied windscreen to reduce wind noise, breath noise, and plosives. With an attached microphone cable nearly 20' long, the mic allows you to maintain a close-up position while pulling your video capture device back for long-distance shots. The included 1/4" TS adapter facilitates proper connectivity to an unbalanced mic input, as commonly found on portable PA systems. Use the tie clip to attach the mic to your subject's clothing; lapels and collars are commonly used. For convenience in storage and transport, the MO-IDL1 comes with a carry pouch.
