SF-16M Matrix Amplier Installation and Operation Guide 9
FlexPort Cat 5 Audio Inputs
The SF-16M includes two FlexPort Cat 5 inputs that accept a variety of pro and consumer
audio sources via optional FlexPort audio modules. See Appendix A for a detailed
overview of all FlexPort modules and system conguration.
FlexPort module options include:
FPM-B Balanced line/mic with phantom power
FPM-X XLR/ 1/4” TRS with phantom power
FPM-D Digital optical/coax
FPM-U Analog RCA
Understanding the FlexPort Audio Bus
Each SF-16M FlexPort input supports:
• Two channels of audio - input can be either stereo or two mono channels (allows two
mono inputs per FlexPort bus)
• RS-485 data pathway - provides 2-way communication between the SF-16M and all
connected FlexPort modules
• 18V power - provides power for two FlexPort modules on a single bus
Daisy Chain FlexPort Modules For Two Mono Inputs Per Bus
All FlexPort audio modules feature a FlexPort Bus In and Out, so any two modules may be daisy chained together for
a two mono source setup. In daisy chain congurations, it is required to assign one module as “Mono 1” and the other
module as “Mono 2” using the dipswitches located on the back of the FlexPort modules. See Appendix A for more
information. Figure 4 below illustrates a daisy chain conguration.

FPM-D and FPM-U: These are natively stereo
input modules - Dipswitch setting should be
“Stereo”.
FPM-B and FPM-X: These are natively mono input
modules - If one mono source input is desired on both
FlexPort bus audio channels, the dipswitch setting
should be set to “Dual M” for dual mono.
