The
MACOM A860
agile modulator is a frequency agile audio/video professional
re-broadcast grade, microprocessor controlled CATV modulator. Attractive and easy to
operate, the sleek design highlights the useful front panel modulation bar-graphs and
channel indicators. The simple push button tuning interface allows the
A860
to be con-
figured for CATV standard, HRC, and IRC or North American broadcast channels with an
RF output of 60 dBmV. The front panel output test point provides a quick reference test
point prior to channel combining equipment, saving time and service interruption during
setup and maintenance. The
A860
features rear panel interface connections for input of
NTSC video and monaural and discrete left and right audio. The integrated stereo
encoder (optional) will provide a BTSC stereo encoded output channel. MPX loop and
4.5 MHz (modulated) audio input connections are provided to bypass the internal stereo
encoder for compatibility with external units; additionally, the MPX loop is useful when
used with the
EAS-12B
emergency override system. A composite audio/video IF loop
provides compatibility with scrambling encoders, ghost cancellers, and IF override appli-
cations. The unit conforms to FCC Docket 21006 for frequency accuracy. The
MACOM
line is backed by an industry leading 5-year limited warranty.
