Sony UTX-P1 Plug-On Transmitter
The UTX-P1 P1 plug-on wireless transmitter converts a wired microphone to a wireless microphone via an XLR connector.
The UTX-P1 plug-on transmitter is designed to be used with Sony UWP series wireless tuners. It's extremely durable and is well balanced for use with the Sony F-112 – a dynamic microphone suited to cost-effective newsgathering applications. The UTX-P1 plug-on transmitter also accepts line-level audio input signal as well. Whether used in a low-cost ENG or EFP system, the UTX-P1 delivers the convenience of uncompromised wireless microphone operation at a very affordable price.

Benefit Key to achieving stable transmission and reception is the use of a stable carrier signal to avoid interference with other frequency channels and to allow the selection of a preferred channel from multiple frequencies. The UWP series achieves this by using a UHF PLL (Phase Locked Loop) frequency synthesized system, which provides the use of accurate carrier signal frequencies. This system is used in both the transmitter and tuners, so that a stable carrier is generated at the transmitter and accurately tuned in at the tuner. This PLL-controlled system provides highly stable , user-selectable frequencies in increments of 125 kHz In general, wireless microphone transmission systems can be subject to reception interruptions (signal dropout), but the UWP series reduces this to a minimum. By utilizing a space diversity reception system, it achieves stable transmission by using dualantenna inputs/reception circuits that receive signals over two different paths and automatically selecting the stronger RF signal for output. The space diversity reception system is adopted in all UWP tuners. In addition, the antennas of the portable and 1/2 rack size tuners each allow for angle adjustments, which helps to further eliminate signal drop out.
When operating a wireless microphone system, it is essential that the tuner not pick up carrier signals transmitted from other systems. In order to avoid this, the UWP series transmitters transmit a 32 kHz pilot-tone signal along with the audio signal. The squelch circuit of the UWP series tuners recognizes this tone signal, and will output the audio signal only when this tone signal is received. This function virtually prevents the output of unwanted signals or noise from other signal transmissions in the air, as well as the RF noise and popping noise that occur when the transmitter is powered on or off.
The UWP series allows simultaneous operation of up to 16 wireless microphones. Optimum combinations of practically tested, intermodulation-free frequencies are stored in the UWP tuners. By using the pre-programmed frequency groups, users can easily choose intermodulation-free frequencies for the transmitters and tuners, simplifying the task of system setup.
