SHURE GLXD14+/SM31-Z4 Безжична микрофонна система headset (за глава)

SHURE GLXD14+/SM31-Z4 Безжична микрофонна система headset (за глава)

GLXD+ е идеалната безжична система за музиканти и водещи. Управлява се автоматично и с пълна надеждност, което ви позволява да се съсредоточите върху работата си. С новата двулентова безжична технология, GLXD+ може да работи както на 2,4, така и на 5,8 GHz, повече от удвоявайки наличната честотна лента, като същевременно интелигентно избягва смущенията за надеждно аудио без прекъсване.

Включената литиево-йонна презареждаема батерия притежава интелигентно презареждане с до 12 часа работа (подобрена от предишното поколение GLXD). Поддържа няколко метода на зареждане, включително бързо зареждане.

Двулентовите предаватели и приемници GLX-D+ не са съвместими с предишните GLX-D или GLX-D Advanced Wireless.
