Interference-free, Affordable Operations
— with the Sony UWP Series
UHF Synthesized 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 Synthesized Wireless Microphone System.
The UWP Series consists of five core elements — a lavalier/bodypack transmitter, a wireless handheld microphone,
a portable tuner, a half-rack-size tuner, and a tuner module. These are available in six 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-the-line Sony
wireless microphone systems, have been incorporated, including the UHF PLL-synthesized 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 Synthesized 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 synthesized
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 utilizing a space-diversity
reception system, it achieves stable
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:
• U models: 758 MHz to 782 MHz or 782
MHz to 806 MHz
(188 selectable frequencies)
• CE models: 798 MHz to 822 MHz or
838 MHz to 862 MHz
(189 selectable frequencies)
• AU models: 792 MHz to 806 MHz
(102 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.
reception by using dual-antenna
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 helps to further
eliminate signal dropout.
Tone Squelch Circuitry
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 handheld microphone and
portable transmitter transmit a 32 kHz
pilot-tone signal along with the audio
signal. The tuner’s squelch circuit
recognizes 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.
