  • TOA wireless microphone tuners rely on Phased Lock Loop(PLL)synthesis for excellent performance levels, stability and reliability. Oscillation frequency changes caused by changes in ambient temperature are kept to a minimum. For a dramatic reduction in noise during changeover between antennas, true diversity and space diversity are now employed. The two truediversity tuner models are equipped with a twin antenna and support condenser microphones. A channel search function is incorporated in all tuners, and a two-line LCD display enables faster meter reading. Remaining battery power indication is also provided.
    The WT-5000 Series tuner units are the 250mA true diversity WT-5800 and space diversity WT-5805, and the 130mA space diversity WT-5810. The WT-5800 and WT-5805 each provide 4 x 16 selectable frequencies, while the WT-5810 provides a 16-frequency selection.
    • TOA true diversity and space diversity circuitry are incorporated in the WT-5000 Series tuners to ensure constant area coverage. Compared to conventional diversity tuners, TOA models come with simpler and more effective circuitry, thus enhancing overall performance and reliability.
