SHURE BLX1288E/SM31-K14 Комбо безжичен микрофон хедсет SM31 + вокален SM58

SHURE BLX1288E/SM31-K14 Комбо безжичен микрофон хедсет SM31 + вокален SM58

Кардиоидният хедсет микрофон SM31FH е предназначен за приложения при които ползвателя е податлив на изпотяване - фитнес инструктаж, аеробика и др. Разполага с отблъскваща влагата конструкция за работа във влажни условия. SM58 е вокален микрофон - лидер в индустрията, пригоден да доставя топла и ясна вокална репродукция. Системата притежава аналогово безжично двойно предаване (двата микрофона могат да бъдат използвани едновременно).

Specifications:

System

• Working Range: 91 m (300 ft) Line of Sight
• Note: Actual range depends on RF signal absorption, reflection and interference.
• Audio Frequency Response: 50 to 15,000 Hz
• Note: Dependent on microphone type
