Easy-to-use features include automatic channel setting function, interchangeable microphone transmitter heads (with over 40 different capsules from various manufacturers available), and superb transient response performance for all ENG/EFP production applications.

IMPORTANT NOTE: This unit is designed for 470.125 MHz to 541.875 MHz (UHF-TV channels 14 to 25) operation. These channels are not available in Brazil.

Digital Audio Processing for High Quality Sound

Improves transient response performance between the UWP-D transmitter and receiver, which will provide impressive natural sound quality compared to conventional analog wireless systems.

Compatible with Sony 800 & UWP Series Analog Audio Receivers

The UWP-D Series transmitters and receivers are also compatible with Sony’s WL-800 Series, UWP Series, and Freedom Series, allowing users to switch between different companding modes. 

NOTE: "Companding" (or, "compansion") is a process by which the detrimental effects of a limited dynamic range channel may be mitigated. The term is a combination of the words "compressing" and "expanding".

Interchangeable Heads with Handheld Microphone

The UTX-M03 handheld microphone transmitter is provided with a Sony uni-directional dynamic capsule. The microphone transmitter also features the option of using interchangeable heads with over 40 different capsules from various manufacturers available (sold separately).

Wide Frequency Coverage

The extra wide switching bandwidth covers a wide area.

Robust Metal Body

The UTX-M03 handheld microphone is made of strong, durable metal, enabling reliable performance in rough operating conditions. 

Fast & Easy Channel Scan

With its Clear Channel Scan, Active Channel Scan function, and IR Sync features, the system detects unoccupied channels and selects the most appropriate channel automatically, for fast and easy system setup.

Automatic Channel Setting Mode

The Auto Set channel mode allows the user to find and set available frequencies to use within the operating frequencies of the system. The receiver will automatically set the transmitter channel using the IR Sync feature.

True Diversity Reception System

The UWP-D system achieves exceptionally stable audio signal, delivered from two independent receiver sections within the unit. Optimum signal quality is delivered by the two receivers sections and a comparison circuit constantly pulls the one with the best signal to give dropout free transmission.

Rechargeable Batteries

The UTX-M03 handheld microphone provides rechargeable battery operation (also available with Ni-MH batteries; contact an AbelCine salesperson for details).

Variable Output Level on Portable Receiver

The system provides variable output level control of ±12dB, for use with the various input levels of camcorders and DSLR cameras.
