OTR-3550-SW
FREQUENCY AGILE - F.C.C. COMPATIBLE
TELEVISION PROCESSOR
1) INTRODUCTION
The Olson Technology OTR-3550-SW is a frequency agile, F.C.C. compatible television processor. This unit
will select any VHF/UHF/cable input channel from 55.25MHz to 801.25MHz and will provide high level
(+60dBmV) outputs on any channel from 7.00MHz (T-7) through 547.25MHz (channel 78) including all
HRC and IRC output channels. All input and output channels are selectable in 0.25MHz increments by front
panel DIP switches, including F.C.C. offsets of +12KHz and +25KHz.
The OTR-3550-SW uses dual SAW filtering for 60dB adjacent channel rejection, and has high level (>60dB)
spurious free output. This unit offers the unique Olson Technology feature of >80dB out-of-band carrier to
noise ratio, which will allow virtually unlimited numbers of the OTR-3550-SW to be combined without the
need for external bandpass filters. The OTR-3550-SW is BTSC compatible and will automatically function
with either stereo or monaural audio carriers.
The OTR-3550-SW has a low power consumption (17 watts @ 115 VAC) for reliable long term operation.
This unit is equipped with a 0.5 amp slo-blo fuse. To maintain proper performance of unit, replace only with an
equivalent fuse.
