EAS 12B 12-Channel Emergency Alert System
EAS12B
12-Channel Emergency Alert System
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 override 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
emergency 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.
Adds FCC compliant
emergency alert capability to any CATV system at
baseband, including those
without accessible I.F. loops
Proprietary baseband switching
methodology eliminates the signal distortion and loss associated with traditional
I.F. switching
BTSC stereo compatibility provides pass-
through for stereo signals
Reconfigurable for 23-channel audio-only
or video-only emergency alert applications
Two or more units can be cascaded to
provide emergency override audio-video
alert on 24 or more cable channels
Compatible with all modulator types and
brands, with or without external I.F. loops
Compatible with all scrambling modes
(Baseband and I.F.)
Internal switching via high-speed field-
effect transistors (FET’s) for instantaneous
video signal transfer without cost and
inconvenience of external switching
devices
High isolation between FET’s eliminates
channel crosstalk and other intrusions into
the downstream path, thereby maintaining
excellent picture quality
Back panel mounted input and output “F”
ports provide easy loop through connections using standard “F” type coaxial
jumpers
Back panel EAS enable-disable contact
provides convenient local or remote activation
U.L. approved switching power supply pro-
vides flexibility for use in international
power system environments
