商品描述

純DC偏壓設計的錄音室用電容型。DC48V的幻象電源專用,具高感度、及高承受入力高等特性。

採用大口徑雙鍍金振動膜的可變型指向性。無指向性、單一指向性與雙指向性等三種指向性可由開關簡單地切換。

高訊噪比且具有寬廣動態範圍。加上可變化的指向性,提升了高品質收音的可能性。

裝備有-10dB的Pad感度衰減開關,及可以有效減低噪音干擾的80Hz,-12dB/oct的低頻衰減電路。

符合歐盟RoHS環保規格。

From the Manufacturer

The 40 Series is a premium line of condenser microphones specially engineered to meet the most critical acoustic requirements of professional recording, live sound and broadcast. Select a model number for detailed product information. The AT4050 features:

  • Transparent uppers/mids balanced by rich low-end qualities combine with advanced acoustic engineering for extensive performance capabilities and highest quality
  • Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone
  • The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use
  • Three switchable polar patterns: omni, cardioid, figure-of-eight
  • Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
  • State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards
  • Switchable 80 Hz hi-pass filter and 10 dB pad
  • Includes AT8449 shock mount
