UHF handheld wireless microphone with half-rack True Diversity receiver - DEFINITIVE AUDIO TD 100 MH

Definitive Audio TD 100 MH is a UHF wireless microphone system comprising a handheld transmitter and a 19" 1U half-rack True Diversity receiver. True Diversity technology and 2 separate antennas significantly improve reception stability, while the PLL phase-locked circuit provides stable characteristics and low harmonic radiation. The receiver features a colour LCD display, an LCD + LED panel display and control buttons for management and configuration. The system operates from 580 to 608 MHz and delivers clear, crisp and precise sound.

The transmitter can reach 13 dBm depending on the region, with transmission power up to 30 mW. The integrated antenna distribution system effectively reduces mutual antenna-radiation interference; frequency grouping provides multiple preset groups compatible with the frequencies in use, while the switching band reaches up to 50 MHz and provides up to 2000 selectable frequencies, depending on the region. The secondary display background colour is adjustable, and the transmitter display colour can be matched to the receiver display. The receiver has a 1U half-rack chassis, and rack-mounting ears are included.

The XLR output is balanced, as is the balanced mix OUT output on a jack connector. The ACT function wirelessly synchronises the transmitter through an infrared interface. The frequency response is flat from 50 Hz to 16 kHz, and the adjustable equalisation processor has 7 bands. The handheld microphone uses a cardioid capsule, modulation is FM, and the oscillation mode is PLL Phase-Locked Loop frequency synthesis. Capture gain is fixed, the receive channel is single-channel, and RF sensitivity is 6 dBμV at input with S/N above 80 dB.

The working range is 60 m in a linear distance; the actual range depends on RF signal absorption, reflection and interference, as well as the environment in which the microphone is used. The silent control mode combines audio code and noise lock. The technical frequency response is 50 Hz to 18 kHz (±3 dB), THD is below 0.5% at 1 kHz, and current consumption is below 130 mA. The receiver measures 20.5 x 4.6 x 16 cm and weighs 1.70 kg. TD 100 MH is suitable for live events and shows, conferences and presentations, broadcast, institutional environments, teaching and training, and DJ use.
