Using MT107 KSK As Noise Cancelling Microphone For Kiosks


The Phoenix Audio MT107KSK is a DSP based, four microphone, beamforming, echo cancelling, noise cancelling microphone array system specifically designed for the various environments that Kiosks are exposed to. Providing increased pick up quality via directed beamforming to a singular point (person talking) in a crowded environment. Phoenix Audio Technologies’ proprietary full duplex, echo canceling, noise canceling, and AGC algorithms prevent gating and the loss of critical information while providing 16KHz of clear HD audio.

Noise Cancelling Microphone Array

Filters out ambient room noise such as air conditioning and background office or traffic noise

Echo Cancelling Microphone Array

Prevents your microphone from transmitting the voice picked up from your speaker

Beamforming Microphone Array

Steering or directing an audio beam to pick up audio only from the direction of the person speaking, while canceling noise from all other directs
