Polsen OLM-20

This dual omnidirectionnal lavalier microphone

Polsen OLM-20

is truly unique.

Which, for two microphones, is already a qualitative very strange! ^_^

Consisting of two microphones Omnidirectional Lavalier OLM-10, the two cables arrive together in one connector, allowing to simultaneously record two different sources on a single 3.5mm microphone jack!

Thus, for any interview, double presentation, or any other activity with several recording sources needed, this microphone will perfectly and discreetly meet your needs, with a very professional quality!

Designed for recording interviews, the OLM-20 Dual Omnidirectional Lavalier Microphone from Polsen is comprised of two of the well-received OLM-10 omnidirectional lavalier microphones. It terminates in a single 1/8" stereo connector, with each microphone recording to a discrete channel on your DSLR, camcorder, or audio recorder with a microphone input. Not limited to just interview applications, the OLM-20 can be used for presentations, podcasts, webcasts, or any situation where more than one subject needs to be recorded.

The OLM-20's dual electret condenser capsules are designed to deliver clear and natural sound, with their omnidirectional polar pattern providing off-axis response, even if the subject turns their head while talking. Both mics offer low sensitivity to wind and handling noise, as well as vocal plosives.

Thanks to its battery-operated design, the OLM-20 can be used with any camera or recorder that supports a 1/8" stereo mic level input, without the need for additional equipment or adapters. Each microphone records to a discrete channel, and the microphones themselves are labeled left and right. Its 13.5' cable provides 10' of distance between each microphone for comfortable placement, while the included tie clips allow for hands-free use.
