Headed Amplifier
An amp head is just a preamp and a power amp section without any speakers. It processes the signal and
amplifies it before it goes into a speaker cabinet. We can find this same formation with some home stereo systems
with a separate amplifier and passive speakers.
Line amplifier
The 20dB Satellite In-Line Amplifier are used to boost the signal from your satellite to your receiver or multi-switch.
Simply install the amplifier at the satellite dish or signal source for an instant 20dB boost. In-line amplifiers are
required when the signal is too weak or for long cable runs over 100 feet. This amplifier supports signals from 900
to 2400 MHz.

Set-Top Box (STB):

Used by TV viewers around the world, set-top boxes (STBs) are devices that connect to the television and convert
cable, satellite, or digital signals, or internet data, to TV signals so video content can be viewed on the television.
Originally used to deliver cable television services to analogue televisions, set-top boxes now come in several
forms and are used to receive and convert digital signals, access cable or satellite television services, or send and
receive internet data via cable or telephone connections.
Some set-top boxes also have a built-in digital video recorder (DVR) for recording content. Also known as
‘receivers’, set-top boxes initially sat on top of the chunkier older-style TV sets (before slimmer flat screens
became commonplace), hence the name ‘set top’.
