TECH TIPS
SF-16M FlexPorts
Category Cable Fabrication and FlexPort
RJ-45 Pinout
It is recommended that all FlexPort bus wiring be
configured using the EIA-568B standard pinout.
Audio Authority cannot guarantee correct operation
using any other wiring configuration. Pre-made
network cables or site-fabricated cables may be used
(EIA-562A or B standard). E-Z Cat 5 cable plugs are
recommended. Always test Category cables with a
network cable tester, not simply a continuity tester;
cables must be paired correctly for proper functionality.
Troubleshooting Guide
Low volume
Check the mic/line dipswitch (FPM-X or FPM-B) when using a mixer or other line level
source. The factory default setting is line level. If volume is still low, adjust the GAIN pot.
Poor sound quality
Make sure two transmitters linked on one bus are set to Mono 1 and Mono 2.
Override button does not
function
Make sure Termination is on. For link, turn off Termination for the transmitter farthest
from the SF-16M. Override must be set up using the setup utility; designate input, output,
and priority.
No mic power
For microphones that accept phantom power, turn PWR Phant. ON.
Only one channel plays
from stereo source
Check the CH. ASSIGN switch. If using linked configuration with stereo sources, use a
stereo to mono adapter to hear both channels in mono.
Override button does not
stay on when pushed
Turn off MOMENTARY/TOGL. dipswitch to activate the toggle function.
Connecting to the SF-16M
FlexPort Transmitters connect directly to SF-16M inputs, or
via other FlexPort Transmitter bus inputs (linked). One or both
FlexPort bus inputs may be shared with up to three SF-16M
amplifiers using the FlexPort bus output jacks. Alternatively, each
SF-16M amplifier in a system can have its own independent
FlexPort transmitters that are only available to the local SF-16M
outputs.
