Product Description
The Toa Electronics WT-4820 Modular Dual-Channel Wireless Receiver combines wireless technology with user benefits such as fast setup, simple operation, and reliable performance. The WT-4820 accepts up to two separately available WTU-4800E01/F01/G02/H01 Diversity Tuner Modules. The modules are available in three different frequency bands with sixteen user-selectable channels in the UHF band (636 to 722 MHz) with simultaneous operation of up to sixteen channels.
Features include individual channel outputs, mix output, and antenna cascade for sharing antennas between 2 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-5270E01/F01/G02/H01 Dynamic for vocals and the WM-5225E01/F01/G02/H01 Condenser for speech. Bodypack transmitters include the WM-5325E01/F01/G02/H01 Rechargeable UHF Bodypack Transmitter. All transmitters offer 10 hours of operation from a 9V 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.
