Easy selection of 94 channels
With its sophisticated phase locked loop (PLL) circuit, the unit can
operate
on
any
one
of
94
carrier
frequencies
in
a
12
MHz
frequency
band
for
each
model,
selected
by
a
simple
button
operation.
Each channel is identified by a number consisting of a 2-digit TV
channel
number
and
a
2-digit
wireless
microphone
channel
number
(example: 68-23).

Operation powered by widely available batteries
The
built-in
DC-DC
converter
allows
stable
operation,
for
up
to
eight
hours continuously, with just two L40 (LR6) alkaline batteries.
CPU and LCD for coordinated operation contro!
The built-in CPU controls the unit operation including the PLL circuit
function. The LCD shows the current channel number, the residual
battery
power,
the
input
attenuation
setting,
the
AF
input
level
and
the
RF output.
Saved channel and input attenuation settings
The unit stores the channel and the input attenuation settings when it is
turned off. The saved settings are retained even if the batteries are
removed. Therefore, when using the unit next time, you need not
make the same settings again.
Highly reliable electronic attenuator
The
built-in
input
level
attenuator
is
adjustable
in
the
range
of
0
io
21
dB
in
3
dB
steps.
It
reduces
signal
distortion
when
an
excessively
strong
input
signal
is
received.
Handy audio input switch (WRT-810A)
You

The unit transmits the RF carrier accompanied by a tone signal,
enabling
the
tuner
with
a
tone
squelch
circuit
to
take
out
only
the
target
audio signal received.
Wide dynamic range and low noise
The compander (compressor/expander) system enables transmission
over a wide dynamic range with minimum noise.
