HMD 27
物品編號 506902

新款 HMD 27 系列頭戴式耳機能夠為廣播評論員和音頻工程師提供最高質量的聲音體驗以及佩戴的舒適性。 HDM 27採用封閉式和環形耳罩設計,這種超輕型設計不僅可以提供一個最大程度的外界噪音衰減,還可以為長時間的工作過程提供最為舒適的佩戴。柔軟的環形耳罩確保了佩戴的舒適性。與此相似的 HMD 26 系列頭戴式耳機具有自動適應的開放式兩段頭帶,因此不會對敏感的頭頂部產生壓力。對於那些更願意選擇傳統方式耳機頭帶的用戶,產品還提供了一個更寬的頭帶襯墊,從而將兩個頭帶轉換為一個簡單的頭帶。

  • 人體工程學輕型耳罩和分離式頭帶(不會對敏感的頭部產生壓力)設計方式帶來了最佳的佩戴舒適性。

  • 能夠為所有需要的監聽需求提供精確和線性的聲音再現

  • 動圈式咪高峰由於其具有的尖銳指向性,使得其在噪音環境中仍然能夠實現聲音拾取的最佳化廣播質量。

  • 主動式降噪(ActiveGard©)開關用來保護噪音峰值大於110分貝時的聽覺系統。

  • 不同形式線纜和支架的模塊化設計理念實現了最佳的靈活性。

  • 所有線纜與26-II系列的線纜完全兼容

  • 可旋轉的耳罩設計能夠滿足單耳聽音的需要

  • 咪高峰能夠佩戴在左邊或右邊

  • 產品附帶的寬大頭帶襯墊能夠將兩個頭帶轉換為一個傳統的單一頭帶

  • What does the NoiseGard on/off switch do?

    The NoiseGard on/off switch is the switch that allows you to turn the active noise compensation circuitry on or off. It comes with a two colors LED for-power on and low battery-on headsets using a battery pack.

    NOTE: If you should turn off the NoiseGard system there is no loss of, or reduction of, the received audio and you still retain the passive capabilities of the headset. You may have to increase the receiver volume to compensate for the increase of ambient noise due to the loss of the NoiseGard feature. The LED is located on the control-unit respective to the battery pack of the headsets. The control unit is included in-line on the models HMEC 45/46 series, HMEC 25/26 series, and HMEC 460 series. An optional battery pack is available for the HMEC 350 series.

  • What is the maximum SPL of a dynamic microphone?

    It is a common saying that dynamic microphones just have no maximum SPL.
    This saying is not technically exactly correct but for every day use use of dynamic microphones you will not find gain limitations. At SPL levels above 160 dB some mechanical problems might occur (for example the voice coil might crash onto the magnet) but these SPL levels are very hard to find in real world.
    Here at Sennheiser we use dynamic microphones for distortion measurements on loudspeakers at very high sound pressure levels. At Sennheiser we have measured the SPL and THD inside a large 2" driver/horn combination with a MD 421. The max SPL this combination was able to produce was 150 dB and the THD level recorded by a MD 421 was below 1% (produced by the driver not by the mic)
    So as a conclusion we can state the MD 421 has no maximum SPL limitations for practical use. However if using dynamic microphones at high SPL levels a user should be aware that the very high voltage (up to several volts) delivered by the microphone might cause problems when connected to mic preamps.
