Functional Description

Forward RF Signal Flow

Before Main & Secondary Paths Split

Describes the initial stages of the forward RF signal path before it diverges.

Main Path (after it splits from secondary path)

Details the forward RF signal path after splitting from the secondary path, leading to the main output.

Secondary Path (after it splits from main path)

Covers the forward RF signal path for the secondary outputs after splitting from the main path.

Return RF Signal Flow

Before the Return Legs Combine

Explains how return signals from multiple ports are received before combining.

After the Return Legs Combine

Details the amplification and equalization of the combined return signal.

Amplifier Powering

Controls and Connectors

Forward Input;Return Output Jack, J1

Routes forward input to amplifier and return output via cable system back to previous amplifier.

Main Output;Return Input Jack, J2

Routes forward output to main cable and return input to amplifier.

Secondary Output;Return Input Jacks, J3 & J4

Route forward output to distribution cables and return input to amplifier.

Input Test Point, TP1

Measures forward input signal at J1 without interrupting operation; return signal not measurable.

Plug-In Circuits

Factory-Installed Plug-Ins

Circuits or jumpers installed at the factory for optimum performance based on customer requirements.

Required Plug-Ins

Positions shipped empty; must be selected and installed based on amplifier's network location.

Optional Plug-Ins

Jumpers or 'zero' circuits shipped for continuity; may need different values based on system design.
