UWPD11/30
Lav Mic, Bodypack TX and Portable RX Wireless System

Benefits: |
PLL Synthesized System |
Achieves stable transmission and reception
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
UWP-D series tuners reduce this to a minimum. By utilizing a
space-diversity reception system, it achieves stable reception by using
dual-antenna inputs/reception circuits. These receive signals over two
different paths and automatically select the stronger RF signal for
output. |
Tone Squelch Circuitry
|
To avoid picking up carrier signals
transmitted from other systems, the transmitter transmits a 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. |
Simultaneous Multi-Channel Operation
|
Optimum combinations of practically tested,
interference-free frequencies are stored in the tuner. 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. |
