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. The AT895 functions equally well for handheld interview use or long-range sound pickup – in the field, in the studio, or in security operations. The Basic System Two components are at the heart of every AT895 System: the AT895 Microphone and the AT895CP Control Pack. The AT895 Microphone itself is "all analog," housing one Audio-Technica MicroLine® element, four A-T cardioid elements mounted in a co-planar diamond configuration, and five mic preamps. The five amplified analog signals from the microphone elements are sent individually down a special detachable cable to the AT895CP Control Pack. The AT895CP Control Pack provides all the power, Digital Signal Processing, and control for the AT895. Output from the Control Pack is analog at mic-level (–23 dBV). The lightweight, sturdy metal housing accepts a quick-change, click-on Battery Housing for totally self-contained operation, if desired. The Control Pack also operates on external 12-14V DC – from an Anton/Bauer or similar-type battery source, or from an AC adapter – via an industry-standard 4-pin XLR-type connection. Control features on the AT895CP are:
  • Three-position Mode (pickup pattern) switch which provides Full-field Adaptive, Planar-adaptive and Line + Gradient settings.
  • Audio filter switch with Flat, High-pass and Band-pass settings.
  • Monitor headphone jack with volume control.
  • LCD battery condition indicator.
  • Power switch with LED indicator.
