Introduction
FlexPort™ Audio Transmitters serve as remote input modules for SonaFlex™ SF-16M Matrix Ampliers. FlexPort
transmitters are available in several different styles. Audio signals are transmitted to an SF-16M via Cat 5e/6/7 cable up
• Four FlexPort styles available: Stereo RCA, Digital Audio, XLR / TRS, and Balanced Audio
• Provides compatability for a mixture of consumer and pro audio sources such as computers, MP3 players, CD and DVD players, audio streaming devices, performance microphones or paging microphones, and audio mixers
• Up to four FlexPort transmitters may be used with one SF-16M (See page 4)
• Convenient Override switch provides a simple user interface at the transmitter location
• Differential balanced line technology eliminates interference, enabling FlexPort transmitters to be located up to 500 feet away from the SF-16M without signal degradation
• Simple connection via one Cat 5/6/7 cable; link two FlexPort transmitters on each SF-16M input
Double the FlexPort Inputs
Normally, one stereo FlexPort transmitter is connected to each of the two SF-16M FlexPort inputs; however, if mono signals are used, two FlexPort transmitters may be daisy-chained on each of the FlexPort bus inputs, doubling the number of possible FlexPort transmitters in one system. There are several ways to congure linked modules. See page 4.
About the SonaFlex SF-16M
The SonaFlex SF-16M is a unique blend of multi-channel amplication, exible input options, audio matrix switching, signal processing and open control capability. Designed and assembled in the U.S. with sound and video integrators in mind, the SF-16M offers better sound with less complexity.

Basic Setup Tasks
1. Read this manual to understand FlexPort functions and behavior.
2. Plan your SF-16M system layout and use the setup utility to assign override behavior, and override priority.
3. Install the SF-16M system, including Cat 5e/6/7 wiring for FlexPort transmitters.
4. Assign FlexPort mono/stereo channels, set other dipswitches as needed.
5. Connect Cat 5 bus to FlexPort transmitters, and connect audio sources.
6. Set SF-16M volume levels (adjust gain if necessary).
7. Cycle power on FlexPort transmitters after any change of settings.
NOTE: If the SF-16M will not be used to control volume, set all SF-16M outputs to -0dB (full volume) and adjust
volume in preamplier.

FlexPort audio transmitters can be used to provide up to four additional audio inputs (2 channels per FlexPort input) to each SF-16M. FlexPort modules connect via Cat 5 cable to the SF-16M and accept a wide variety of pro and consumer audio sources. FlexPort modules can be located up to 500 feet from the SF-16M and include mounting points for either surface or in-wall mounting in an “open ended” single gang bracket such as Arlington model LV1 or Carlon model SC100RR. Remove unused mounting tabs with pliers before installation.

Each SF-16M FlexPort input supports:
• Twochannelsofaudio - input can be either stereo or two mono channels (allows two FlexPort transmitters per bus)
• RS-485datapathway - provides 2-way communication between the SF-16M and all connected FlexPort modules
• 18Vpower - provides power for up to two FlexPort modules on a single bus
FlexPort Override
In addition to the 10 overrides available in the SF-16M, there is an override command for each channel on each FlexPort bus input (see table). Each FlexPort override button sends a discrete override command to the SF-16M that can be programmed to connect the associated override channel to any output(s). When used in stereo mode, the Left channel override command connects both left and right to the assigned output(s). FlexPort input channels can be selected independent of an override command. FlexPort channels are numbered 17, 18, 19 and 20 for SF-16M setup.

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.

All FlexPort audio modules feature a FlexPort Bus In and Out, so any two modules may be linked together for a two source (mono) setup. In linked congurations, it is required to assign one module as “Mono 1” and the other module as “Mono 2” using the channel assign switches located on the back of the FlexPort transmitters. Stereo FlexPort transmitters can assign the left or right channel to be active on the bus. When using a linked conguration for stereo sources, combine the stereo channels into mono before connecting them to a FlexPort transmitter.

The override button on a FlexPort front panel is used to switch designated SF-16M outputs to a FlexPort input. When the override button is pressed, it triggers a programmable override event (see setup utility). A typical application would be an audio mixer, connected to an FPM-X in a conference room. Normally background music is playing from a source connected to the SF-16M. When the override button is pressed, designated outputs switch from background music to the audio mixer for the duration of the override. When the override button is pressed again, (in Toggle mode) all affected outputs switch back to the background music source. When two FlexPort transmitters share a single bus, they must be set to operate independently, or to mix their signals, as shown in the example below.
Override behavior is based on two key settings:
1. FlexPort dip switch settings (see page 5).
2. SF-16M audio override settings, programmed using the SF-16M PC conguration utility (see the setup utility manual for more information on audio override settings).
Example: Mix Option Enabled
In some cases it may be desired to mix together
inputs from two FlexPort transmitters when both
audio overrides are active. An example would be a
conference room where both a microphone and an
audio presentation should be heard simultaneously.
• Set one FlexPort as “Mono 1”, and set the other as “Mono 2”.
• Turn on the “Mix” dipswitch on one of the transmitters, so that the SF-16M will mix the channels together for all outputs in the system.
• In the setup utility, designate outputs for overrides (e.g. 17 and 18).

Figure 5. In this example, a microphone is connected to an FPM-X transmitter, and DVD player audio outputs are connected to an FPM-U transmitter. Both FlexPort transmitters are on the same Cat 5 bus run. Both transmitters have the Override switch on and one transmitter has the Mix switch on. When the override switch is active on the Mix transmitter, the audio from both transmitters is mixed by the SF-16M for output to all speakers in the conference room.
NOTE: In this case, the overrides for both transmitters (17 and 18) are programmed to perform the same action,
so the override may be triggered or cancelled from either transmitter.

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
ampliers using the FlexPort bus output jacks. Alternatively, each SF-16M amplier in a system can have its own independent
FlexPort transmitters that are only available to the local SF-16M
outputs.

It is recommended that all FlexPort bus wiring be congured using the EIA-568B standard pinout. Audio Authority cannot guarantee correct operation using any other wiring conguration. 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
No mic power For microphones that accept phantom power, turn PWR Phant. ON.
Only one channel plays from stereo source
Override button does not stay on when pushed
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.
Check the CH. ASSIGN switch. If using linked conguration with stereo sources, use a stereo to mono adapter to hear both channels in mono.
Turn off MOMENTARY/TOGL. dipswitch to activate the toggle function.
