Speaker Amplifier Module Basics
The 4M09 Speaker Amplifier Module is designed to connect to an external speaker. The module can
greatly amplify the audio to properly drive a large external speaker using a long cable. The external
speaker can then be placed in an ideal location to broadcast the audio in a large room.
There is no audio "input" on a speaker amplifier module. It is only used to supply audio to a speaker.
Installing the Module
1) With the G-400 series system powered off, insert the speaker amplifier module into a slot on
the back. (You can insert the module while the system is powered on, but doing so is not
recommended because it may disrupt ongoing communication.)
2) After the module is well seated, tighten the thumb-screw on the module to secure the module
and to help reduce RF interference.
3) Power on the G-400 series system and wait for it to indicate "System Running" on the front
panel display.
4) Browse to the user interface on the G-400 using any
standards-compliant web browser. (If needed, refer to
the G-400 Quick Start Guide for assistance with this
step.)
5) Verify that the speaker amplifier module is visible in the
G-400 Link Builder interface. It will be visible as a module on the left hand side with the name
