Product Description

The DA-250 is a small Compact Stereo Array Microphone and Digital Signal Processor (DSP) circuit board platform that can easily be integrated into many different OEM devices that would greatly benefit from directional noise canceling microphone performance, but in the past has been unattainable with an embedded microphone configuration.

Requiring only two tiny holes in the faceplate of a device, the DA-250 OEM Array Microphone can deliver directional microphone sensitivity without the need for acoustic baffling, as found in large parabolic waveguides or long shotgun tube type microphones.

The DA-250 is perfect for systems that demand superior microphone sound quality and performance for speech recognition accuracy and/or communication system intelligibility, while at the same time requiring the user to speak at distance from the microphone. Superior sound quality far-field/hands-free microphone performance.

System Configurations: Stereo Array Mic w/DSDA (Beam Forming and & Noise Reduction), Stereo Array Mic w/DSDA3 (Aggressive Beam Forming and Noise Reduction), Mono Microphone w/EchoStop (Full Duplex Echo Cancelation and Noise Reduction).
