The Pico Macom EAS12B is the most user friendly 12 channel professional re-
broadcast grade audio-video emergency alert system on the market. It enables
users, via a local or remote contact closure to simultaneously override up to 12
video and audio channels (monaural or BTSC stereo) with one video/audio over-
ride source. Alternately, the unit can be daisy-chained to override 23 channels
with an audio or video-only override source. The EAS12B interrupts the primary
signals at baseband level instead of breaking into the I.F. loop, eliminating the
signal distortion and loss associated with traditional I.F. switching and providing
compatibility with all I.F. loop and non I.F. loop modulators. The EAS12B
employs CMOS field effect transistor (FET) switching for instantaneous transfer
to and from the override source while maintaining very high isolation between
input and output ports.Two or more units can be cascaded to provide emer-
gency override audio-video alert on 24 or more cable channels. All connections
are via industry standard “F” type coaxial jumpers. Pico Macom backs up this
product with its industry leading 5-year limited warranty.
