✧ INTRODUCTION

Interference-free, Affordable Operations – with the Sony
UWP Series UHF Synthesised Wireless Microphone System

As the use of wireless microphone systems has increased dramatically for diverse applications, low-cost systems
have become more popular, but transmission stability and noise problems have often been overlooked.

Sony presents the ideal solution for budget-conscious users seeking rock-steady wireless operations — the UWP
Series UHF Synthesised Wireless Microphone System.
The UWP Series consists of six core elements — a lavalier/bodypack transmitter, a wireless handheld microphone,
a plug-on transmitter, a portable tuner, a half-rack-size tuner and a tuner module.These are available in seven turnkey
packages, each comprising a microphone, transmitter and tuner, for a ready-to-go system straight out of the box.
Each package has been carefully compiled to address specific operational needs, meaning the UWP Series can
virtually adapt to almost any application.
The UWP Series excels in transmission stability. Sophisticated wireless technologies, developed for top-of-the­line Sony wireless microphone systems, have been incorporated, including the UHF PLL-Synthesised system,
space-diversity reception and a tone squelch function. These capabilities are typically found only on high-end
wireless systems.

Whether you use it with low-cost ENG, EFP or PA systems, the UWP Series delivers the convenience of
non-compromised wireless microphone operation at a very affordable price.

STABLE TRANSMISSION AND RECEPTION

The UWP Series Wireless Microphone System uses three core
technologies to provide stable transmission and reception:

PLL Synthesised System

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 Synthesised system,
which provides accurate carrier signal frequencies.
This system is used in both the transmitters 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.

Space Diversity Reception System

Typically, wireless microphone transmission systems can be
subject to reception interruptions (signal dropout), but the UWP
Series reduces this to a minimum. By utilising a space-diversity
reception system, it achieves stable reception by using dual­antenna inputs/reception circuits. These receive signals over
two different paths and automatically select the stronger RF sig­nal for output. The space diversity reception system is adopted
in all UWP tuners – the portable tuner, half-rack-size tuner and
tuner module alike. What´s more, the antennas of the portable
and half-rack-size tuners each allow for angle adjustments,
which help to further eliminate signal dropout.

Tone Squelch Circuitry

When operating a wireless microphone system, it is essential
that the tuner does not pick up carrier signals transmitted from
other systems. In order to avoid this, the UWP Series transmit a
32 kHz pilot-tone signal along with the audio signal. The tuner´s
squelch circuit recognises this tone signal and outputs the
audio signal only when this tone signal is received. This function
prevents the output of unwanted signals and 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.

PRE-PROGRAMMED OPERATING FREQUENCIES

The transmitters and tuners included in the UWP Series
incorporate pre-programmed frequencies that meet the
wireless-communication regulations of each country. The UWP
Series operates within the following frequency ranges: 798 MHz
to 822 MHz or 838 MHz to 862 MHz (189 selectable
frequencies).

SIMULTANEOUS MULTI-CHANNEL OPERATION

The UWP Series allows simultaneous operation of up to 16 wire­less microphones. Optimum combinations of practically tested,
interference-free frequencies are stored in the UWP tuners. By
using the pre-programmed frequency groups, users can easily
choose interference-free frequencies for the transmitters and
tuners, simplifying the task of system setup.
