Atlantic HAL 1200, User Manual

Page: 2 / 23

A - Introduction
Thank you for purchasing the HAL 1200 Atlantic.
(Automatic Transistorized Linear Amplifier No Tune Inside Computerized).
This compact and lightweight desktop HF + 50MHz linear power amplifier has
a maximum input power of 2.4 KW.
Our solid-state broadband power amp technology makes it the smallest and
lightest in the industry.
Typical output power is 1200W PEP/SSB with the drive power of 25-35 W.
The built-in band decoder will allow you forget about the band setting, without
any data connection to the transmitter, or when the amplifier is connected to
the modern radio through these cables band data as Yaesu BAND DATA,
Icom CI-V, Kenwood RS-232C or IF-232, Elecraft BAND OUT.
B - Cautions
B-1 Unpack the amplifier, check the fan guard at the rear panel Fan to see if
there is any damage caused by the physical shock during the transportation.
Fan blades must be free to rotate when powered.
The amplifier is cooled by forced airflow. Several inches of clearance on the
top and the rear wall are necessary to allow for smooth air intake into the fan.
B-2 Keep the amplifier out of direct sunlight, in a cool dry environment.
B-3 Internal high voltages, (AC, DC and RF), are present at all times, ON
AIR or OFF. Internal access should be limited to avoid injury.
B-4 Turn off the AC main power immediately upon any unusual sounds,
sights or odors. Check readings the display for Warning messages, the fuses
and all cable connections around the amplifier. Please notify the dealer or the
factory of any problems.
B-5 For your safety, do not operate the amplifier without adequate
grounding. A proper ground connection will result in peak performance and
stability, in addition to reduced RF strays or noises.
B-6 To eliminate the RF interference to such home appliances as TV, FM
radio, telephone sets, etc., it is recommended that clamp-on ferrite cores be
inserted at both ends of the remote control cable, coaxial jumper cable, and
antenna cables, as needed. Also, a common mode AC line filter (near the AC
outlet), and in-line low pass filters on the antenna coaxial cable, (as
necessary), are recommended.
