Fully Assembled • Export Model • High Power 1W (Approx) Output • Used, Good Condition • Tested/Fully Working • FM Stereo Transmitter • Great for Church Service or Yard-Casting
Here's a used top of the line FM transmitter, ideal for
sending audio over local distances so that you can listen to
your church services, webinars, drive-in movie audio,
internet radio, MP3's etc while wandering around your house,
yard parking lot etc. Based upon the installed final power
amplification stage I believe that
this is the FM100B Export version with approx. 0.5W to 1W output
power. The actual output power can be adjusted via R36 on
the circuit board. A telescopic antenna can't be used unless
you have the output power dialed down low as the lack of
accurate antenna tuning will burn out the power amplifier.
So this needs to be used with a matched antenna [not
included] connected to the rear panel BNC Connector.
Important: if you power it up with no antenna connected (or
with an un-tuned antenna) you will most likely burn out the
final output stage. Full product details may be obtained
from the user manual at https://www.prostudioconnection.net/2007/Ramsey_FM100B_Manual.pdf.
For greatest range, a roof mounted antenna will get
better results (as will just raising any matched antenna). This
is
a fully-built unit which the factory no longer sells.
There's a 3.5mm jack on the rear panel which I think may
have been used for composite I/O but this is not
guaranteed. It can be ignored if this is isn't useful
to you.
Note: The purchaser is responsible for complying with
all FCC rules & regulations within the US or any
regulations of their respective governing body and by
purchasing indemnifies the seller against any
consequences from their improper use of this equipment.

This professional synthesized transmitter is adjustable directly from the front panel with a large LED digital readout of the operating frequency. Just enter the setup mode and set your frequency. Once selected and locked you are assured of a rock stable carrier with zero drift. The power output is continuously adjustable throughout the power range of the model selected. Audio quality is equally impressive. A precision active low-pass brick wall audio filter and peak level limiters give your signal maximum "punch" while preventing overmodulation. Two sets of stereo line level inputs are provided with front panel level control for both. Dual front panel LED bargraph meters provide left and right channel audio level metering. In addition to the line level inputs, there is a separate microphone input with a built-in mic mixer to control the level. Not enough? How about unattended microphone ducking! When enabled, the presence of mic audio automatically reduces and overrides the line level input! Just like the professional units at a fraction of the cost.
The FM100B includes an attractive metal case, a whip antenna and internal power supply.
