TELEX BTR800/B4 ( Frequenza 536-554/668-686MHZ )
UHF, frequency agil, 2 channel wireless intercom base station with stage announce and
WTA/ISO function 4 pin male XLR for headset
The RTS RadioCom BTR-800 UHF-synthesized wireless intercom systems offer the ultimate
in reliable, high performance, high fidelity full-duplex communications The BTR-800
system includes the BTR-800 frequency-agile base station, working with up to four (4)
TR-800 or TR-825 frequency-agile beltpacks The BTR-800 base station provides
full-duplex communications with the beltpacks The BTR system incorporates two (2)
audio channel operation, permitting the beltpack operator to choose between two (2)
separate audio channels of communications, with the base station tracking the beltpack
selection This allows the user the flexibility to create a party line and a private
line within the same beltpack
