A New Standard in Audio Acquisition AT895 Systems incorporate a revolutionary DSP-controlled five-element microphone array that provides adaptive directional audio acquisition. Utilizing Audio-Technica's proprietary DeltaBeam® technology, the AT895 System manipulates and filters the output of the array by acoustical, analog and digital means. This process enhances the pickup of a sound source from a desired direction relative to unwanted background noise or interference, providing cancellation of up to 80 dB. Background interference, mechanical noise, wind noise, proximity effect – all are minimized automatically. And, unlike some attempts at directive devices, the audio quality remains wideband and natural.
