The following subparagraphs provide removal and installation instructions, parts recognition, and
electrical information for select miscellaneous SAM components.
4.10.1
Audio Amplifier
The SAM four-channel audio amplifier (Figure 77) is mounted by the OEM/apparatus builder. The
amplifier accepts audio signals from the Pump Controller via the ground loop isolator (Figure 78)
and provides four 300 W outputs (into 4 Ω or 2 Ω for up to 1200 W max) to the speakers.
Note the amplifier utilizes an in-line 10A fuse holder, always check for a blown fuse first.
The SAM audio amplifier is installed by the OEM/apparatus builder, refer to the OEM/apparatus
builder documentation for audio amplifier location, mounting, and R&R information.
