Definitive Audio Td 200 Mh

A modern UHF system designed for stage and installations

This system follows the logic of professional UHF links: reliable transmission, extended frequency selection, and user-friendly ergonomics. The 1U chassis format allows for neat rack mounting, while the True Diversity design (with 2 separate antennas ) aims to secure reception in busy environments (multiple RF sources, stage lighting, metal structures, proximity to other wireless systems).

The inclusion of an integrated antenna distribution system is a real advantage to limit interference caused by mutual radiation: it improves clarity and ease of use when multiple RF elements coexist. The whole system is also designed to be easy to read, thanks to color LCD screens and a harmonized display logic between receiver and transmitters.

Who is it for and what are the uses?

This dual handheld microphone system is particularly suited for hosts, speakers, sound providers, multipurpose rooms, places of worship, and bands seeking an efficient solution for two simultaneous speech inputs or two voices. The microphones' cardioid capsule helps prioritize the source facing the microphone and reduce some ambient noise, an asset in live environments (audience, stage monitors, room sound reinforcement).

With a frequency response advertised up to 16 kHz (and up to 18 kHz on the receiver side depending on settings), the sound is designed to remain intelligible and natural for voice. The working range specified at 60 m linear distance meets common needs in rooms, conferences, or small to medium stages, while maintaining the main goal: a stable and usable link.

Key features: RF stability, readability, and useful settings

Frequency stability and wide tuning capacity

The PLL phase-locked frequency synthesis contributes to stability and repeatability of settings. Depending on the region, the tuning bandwidth can reach 50 MHz with up to 2000 switchable frequencies, facilitating avoidance of disturbed channels and integration with other existing wireless systems.

Infrared ACT: quick pairing

The ACT function allows wireless synchronization of the transmitter via an infrared interface. In practice, this speeds up setup: the frequency is set on the receiver side, then transmitted to the handheld microphone, reducing errors and smoothing configuration changes.

Clear and coherent interface

The receiver offers 2 color LCD screens and a display organization including 1 main control + 4 sub-channels with function display. The adjustable background color and color matching between transmitter and receiver improve quick identification, useful when managing multiple channels or artists.

Connectivity ready for sound reinforcement

On the output side, you have 2 balanced XLR outputs to feed a console or stagebox, as well as a Mix Out output on a balanced 6.35mm Jack for convenient summing. The kit includes expected elements for integration: rack ears, antenna mounts, and 2 antennas dedicated to more robust reception.
