WT-4820

THE TOA WT-4820 MODULAR DUAL CHANNEL WIRELESS RECEIVER combines cutting-edge wireless technology with user benefits such as fast setup, simple operation, and reliable performance. The WT-4820 accepts up to two WTU-4800 Diversity Tuner Modules available in 3 different frequency bands with sixteen user-selectable channels in the UHF band (636 - 722 MHz) with simultaneous operation of up to sixteen channels. Features include individual channel outputs, mix output and antenna cascade for sharing antennas between two units. A convenient Mix-in jack allows the connection of the audio output of a second WT-4820 or other source. Handheld transmitters include the WM-5270 Dynamic for vocals and the WM-5225 Condenser for speech. Bodypack transmitters include the WM-5325 Rechargeable UHF Body-pack Transmitter. All transmitters offer ten hours of operation from one nine volt battery with low battery indication. The bodypack transmitter also has a recessed on/off switch to prevent accidental shut-off and a rotatable bodypack clip for versatile mounting.

All TOA wireless systems are FCC and UL listed, and are backed by a five year warranty.
