The 470 to 542 MHz version of the Sony UWP-D21 Integrated Digital Wireless
Bodypack Lavalier Microphone System features all-metal construction, easy to
read LCD displays, wide switching RF bandwidth, USB power and charging,
automatic channel scanning, infrared synchronization between transmitter and
receiver, Mic/Line switchable input on the bodypack transmitter, true diversity
receiver, PLL-synthesized tuning, headphone output on the receiver, output gain
controls on the receiver for optimizing the input level into a camera, and
digital companding circuitry. The package is suitable for a wide range of
wireless applications such as ENG, documentary work, talk shows, conferences,
and more.
The system is referred to as integrated digital because the transmitter and
receiver utilize DSP for digital companding and expanding of the transmission
signal. Performing the companding and expanding processes in the digital domain
improves the accuracy and transient response of the received audio.
The camera-mountable receiver features true-diversity technology, which
stabilizes reception and minimizes RF interference by using dual antenna
input/reception circuits and selecting the strongest incoming signal. The angle
of the antennas is also adjustable to improve reception when the receiver is
mounted on top of a camera or camcorder. The system utilizes UHF Phase Locked
Loop (PLL) synthesis to lock the phase of the transmission frequency between
transmitter and receiver. The receiver can automatically search for an available
transmission frequency and link the desired frequency to the transmitter via
infrared connection.
A stereo mini-jack output with monitor volume control is included, and both
stereo mini and stereo XLR cables are provided. The unit also includes a
headphone monitor output for use with cameras and camcorders that don't have a
monitor output. An LCD display provides channel and frequency information,
battery life, RF-input level, audio output status and accumulated operating
time.
For power, the receiver operates on two AA batteries for up to 6 hours, or
on 5 VDC of USB power over a USB micro-B cable. The USB connection can also be
used to recharge Ni-MH rechargeable batteries within the battery cartridge. The
receiver's compact design and included shoe-mount adapter allows easy mounting
to most camcorders and interchangeable lens system cameras.
The improved bodypack transmitter features a mic- and line-level switch for
standard wired microphone or line-level sources. Selectable transmission output
power provides a choice between 5mW output, which is suitable for simultaneous
multi-channel operation, or 30mW output for long-distance transmission.
The transmitter can operate for up to 8 hours on two AA-size alkaline
batteries, be powered or recharged via USB micro-B connection, and features a
comprehensive LCD display.
The system comes with an omnidirectional lavalier microphone, a windscreen
for the microphone, a microphone holder clip, two belt clips, a shoe-mount
adapter, a mini to mini stereo cable, and a mini to XLR cable. Optional
accessories such as a battery case and soft case for the receiver are sold
separately.
Digital Companding
Utilizes analog-to-digital and digital-to-analog converter stages so that
the transmission signal can be digitally companded by the transmitter and
digitally expanded by the receiver for improved audio transient response
Automatic Channel Scanning
Scans for available transmission channels and then syncs the transmitter to
the receiver via infrared
Frequency Coverage
Provides up to 72 MHz of transmission bandwidth
UWP Series / WL-800 Series Compatibility
Enables cross-compatibility between the UWP-D transmitter with a UWP Series
or WL-800 Series receiver or UWP Series or WL-800 Series transmitter with a
UWP-D receiver
Headphone Output
Enables direct monitoring of receiver via headphones; especially useful for
cameras that lack a monitor output
USB Power Options
Supports USB powering and USB charging of internal Ni-MH rechargeable
batteries placed in the battery cartridge
Output Level Control
Controls the receiver's output level with ±12 dB adjustments for optimizing
the input level into the camera
UHF Phase Locked Loop (PLL) Synthesized Frequencies
Provides stable transmission and reception by generating a transmission
frequency and locking the phase of the transmission signal to the incoming
signal of the receiver
True Diversity Reception
Utilizes dual-antenna reception circuits and selects the stronger incoming
signal to reduce drop-outs
Tone Squelch Circuitry
Transmits a pilot-tone signal with the audio signal and only outputs the
audio signal if the pilot tone is present to reduce RF interference from other
sources
Mic and Line Input Switch
Enables switching between microphone- and line-level inputs
Simultaneous Multi-Channel Operation
Stores the most stable interference-free transmission frequencies to
internal memory for rapid setup and switching between frequency groups
Selectable RF Output
Allows selection between 5mW output power and 30mW output. 5mW is suitable
for indoor, simultaneous multi-channel operation while 30mW is intended for
outdoor, long-range use
Visual Display
Both transmitter and receiver feature a comprehensive LED display providing
channel and frequency information, battery life, total usage time and more
Improved All-Metal Construction
The transmitters and receiver feature metal construction for
durability
