UT Transmitter

UT Transmitter  
Digital Hybrid Wireless® Handheld Transmitter

The UT Digital Hybrid Wireless® is a state-of-the-art 100mW handheld transmitter incorporating many advanced features to provide high-quality speech and vocal performance. The proprietary VariMic® preamp allows custom tailoring of the microphone's frequency response, while a digitally-controlled input limiter ensures distortion-free audio over a very wide dynamic range. A stepped attenuator control gives the user a precise gain adjustment for optimum signal to noise performance. Along with providing peerless audio quality in native 400 Series mode, the Digital Hybrid Wireless® technology found in the UT includes compatibility modes for Lectrosonics 200 Series, 100 Series systems and IFB receivers, and some systems from other top manufacturers.


At the heart of the UT is the VariMic® preamp, included with each of the three different electret condenser capsules. The elements are mounted on a tuned suspension to reject handling noise, while a generously sized windscreen prevents popping and breath noise. The preamp board also includes three tone controls and one variable attenuator, allowing the user to tailor the microphone's audio without changing the capsule.

VMC


VMC Cardioid Capsule - This element has excellent frequency and transient response rivaling the top condenser performance microphones on the market. The pickup pattern is a standard cardioid with exemplary off-axis response, allowing the talent to move around the microphone without a change in tone. The extended high-frequency response produces an open, clean sound with excellent intelligibility.

VMC

VMS Supercardioid Capsule - In applications where maximum gain before feedback is required, the VMS capsule is the right choice. With its nearly perfect super-cardioid pattern, the AKG C5900 capsule rejects sounds from the rear and rear sides, while providing a generous frontal "live" area. The VMS is slightly lower in sensitivity when compared to the VMC.

VMC

VMO Omnidirectional Capsule - The omni capsule is perfect when the talent may need to be off-axis, such as in an interview situation. Also, omni capsules by nature are much more immune to handling, popping and wind noise than directional microphones. In addition, this capsule has slightly higher sensitivity than the VMC cardioid capsule.

Digital Hybrid Wireless® is a revolutionary new design that combines digital audio with an analog FM radio link to provide outstanding audio quality and the exemplary RF performance of the finest analog wireless systems. This overcomes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor. Instead, it is a technique which can be accomplished only in the digital domain. The process eliminates compandor artifacts, expanding the applications to include test and measurement of acoustic spaces and musical instruments.
