The freePORT systems
Designed for different areas of application, the freePORT systems are
available in three variants.
y Presentation Set:
This system is ideal for presentation applications. The unobtrusive
ME 2 clip-on microphone is virtually invisible.
y Instrument Set:
This system is for connecting musical instruments (e.g. guitar) which
have a ¼” (6.3 mm) ja ck socke t directly to the bodypack transmitter.
y Vocal Set:
This system is ideal for vocal and speech applications.
Transmitters and receivers of the freePORT systems have four factorypreset frequencies for direct channel selection – ready for immediate
use after switch-on.
The freePORT systems are available in three UHF frequency ranges:
y Frequency range A: 719 to 721 MHz
