Description
The HDA Series of 19” rack mount headend distribution amplifiers are completely self-contained broadband devices,
specifically designed for the distribution of digital and analog CATV signals in the frequency range from 47 to 860 MHz.
The HDA is unique in that it integrates the functions of a passive combiner and a distribution amplifier into a single
high performance unit.
State of the art hybrid power doubling amplifier modules enable the unit to operate at high output levels while
maintaining low distortion characteristics. Four combiner configurations of 16, 12, 8 and 4 ports are available.
A -30 dB low-level backmatched test port is externally accessible enabling easy in-service testing and adjustment.
The chassis design affords excellent heat dissipation allowing operation at high ambient temperatures without
sacrificing reliability. Plus, the HDA has a built-in standby power supply with automatic switching capabilities.
Features
• Fully integrated combiner and distribution amplifier
• Front panel accessible gain and slope controls for easy adjustments
• Combiner attenuator for adjustment control of digital and analog channel ratios
• State of the art hybrid IC circuitry for high output with low distortion
• Exceptional temperature stability range
• Aluminum chassis for superior heat dissipation

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.
The lightning flash with arrowhead 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 constitute 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 maintenance (servicing) instructions
in the literature accompanying
the product.
TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER FROM THIS UNIT.
NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
