AP Series
Instruction Manual
Description
AP Series are frequency agile TV channel processors that provide visual and aural RF carrier outputs on any Broadcast or
CATV channel in the full 50 to 550 MHz (AP xx-550B) or 750 MHz (APxx-750B) frequency range from any VHF or UHF RF
input source. They have an exceptionally low out of band noise floor that permits the construction of multiple channel
headends without auxiliary filtering. Efficient AGC assures a wide dynamic range and dual SAW filters provide superior
selectivity.
The processors are available in either 60 dBmV (AP 60-xxx) or 40 dBmV (AP 40-xxx) output versions. DIP switches for
setting the input and output frequencies are accessible from the front panel, as are the A/V ratio, output level, FCC
aeronautical offset controls and flatness control.
An external IF loop-thru enables the replacement of the standard IF signal with an alternate source of composite IF
(such as an “all-call” system) or the insertion of IF scrambling equipment. An on-board carrier substitution generator is
automatically activated upon loss of input signal. A high isolation IF switch is included to allow for an EXT IF input which
can be used for EAS capability.
Options
04 = Sub Band Output
12 = Automatic Broadcast Offset Correction
14 = On Channelock
17 = Sub Band Input (AP 60-xxx)
20 = Digital Control, Serial RS-232/TTL Loop
WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV System Installer’s attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be
connected to the grounding system of the building, as close to the point of cable entry as practical.

RISK OF ELECTRIC SHOCK
DO NOT OPEN
The lightning flash with arrow-
head symbol within an equilateral
triangle is intended to alert you
to the presence of uninsulated
“dangerous voltage” within the
product’s enclosure that may be
of sufficient magnitude to consti-
tute a risk of electrical shock to
persons.
The exclamation point within an
equilateral triangle is intended
to alert you to the presence of
important operating and main-
tenance (servicing) instructions
in the literature accompanying
the product.
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER FROM THIS UNIT.
