T-522UH/ T-522UT/ T-522UL/ T-522UV/ T-522US

Feature

Single display dual channel.
The receiver uses advanced PLL phase-locked loop and microcomputer CPU control system and is compatible with manual frequency selection and automatic infrared frequency locking.
The receiver system adopts high performance speech companding technology to provide perfect sound quality.
Support 6 sets of 12 frequencies being used at the same zone without interference with each other.
Applicable to classrooms and conference rooms, etc.
