HMD 27
Professionelt broadcast-headset til kommentatorer og teknikere, specielt for OB-produktioner

HMD 27
Varenummer 506902

Den nye HMD 27-serie inviterer kommentatorer og lydteknikere til at opleve det højeste niveau af komfort. HMD 27 er en lukket, circumaural hovedtelefon, designet til at levere effektiv passiv støjdæmpning, men ikke desto mindre usædvanlig let og komfortabel, selv ved lang tids brug. Bløde circumaurale ørepuder sikrer en behagelig pasform. I lighed med HMS 26-serien har headsettet en automatisk åbnende, todelt hovedbøjle, som ikke trykker på den følsomme isse. For brugere, som foretrækker en konventionel hovedbøjle er der inkluderet en bred pude, der forvandler den dobbelte bøjle til en enkelt.

  • Fremragende bærekomfort takket være letvægts circumauralt design og todelt hovedbøjle (intet tryk på den følsomme isse)

  • Præcis og lineær lydgengivelse til meget krævende monitorering

  • Dynamisk mikrofon, der udmærker sig ved en stærk og kraftfuld lyd til audiotransmission i højeste broadcastkvalitet, selv i støjende miljøer.

  • ActiveGard© (m. afbryder) beskytter mod støjtransienter > 110dB

  • Modulært system af forskellige kabler og boom-arme giver størst mulig fleksibilitet

  • Kabler i 26-II serien er kompatible

  • Drejelig ørehøjttaler muliggør enkeltsidet lytning

  • Mikrofonen kan bæres både til højre og venstre

  • Inkl. bred pude, som konverterer den dobbelte hovedbøjle til en kompakt enkelt bøjle.

FAQ
  • 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.
