DB-25 Audio Connections

The DB-25 input on the SF-16M serves two purposes:

1. Source audio link between SF-16M units: When multiple SF-16M units are linked together, the DB-25 audio input
receives source audio from the DB-25 audio loop output of the previous SF-16M. The source audio originates from the
RCA audio inputs or the DB-25 audio input of the rst SF-16M chassis. (See gure 2 below).

2. Direct input from an Audio Authority audio matrix: In scenarios where the SF-16M is serving as an amplier for
Audio Authority audio matrix switchers such as the ADX-0808/ADX-1616 and the HLX 2278 audio output card (See Illus­tration below). In this scenario, the SF-16M receives all audio content from the ADX or HLX and passes the audio through
to the amplied outputs. The HLX or ADX provides all of the matrix switching (See gure 3 below).

• 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 two modules may be daisy chained together for a two
mono source setup. In daisy chain scenarios, 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 ? for more information. Fig­ure 4 below illustrates a daisy chain conguration.

Single FlexPort Module Connection For One Stereo or Dual Mono Input

When connecting a single FlexPort audio module to a FlexPort bus input (See gure 5 below) it is necessary to congure
the audio modules as shown below.

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.

The SF-16M includes 16 amplied audio outputs that can be congured as mono, stereo or a combination of both mono
and stereo. Figure 6, shown below, provides examples of each conguration.

NOTE: It is important that all physical speaker output congurations are entered into the SF-16M programming, using the
PC conguration software or the front panel system menu.

Speakers and Impedance

Each ampler output of the SF-16M can support a 4 Ohm speaker load. In many cases only a single speaker is con­nected per amplier output, so any speaker with a 4 - 8 Ohm impedance rating is acceptable with the SF-16M. However,
in cases where you may wish to connect more than one speaker per output, it is important that you understand speaker

impedance and basic Ohms law.

There are numerous resources which explain imped­ance and ohms law in detail, so we will not cover
it here. However, for practical purposes, we have
included a chart (Figure 7) which lists a specic limit
on how many speakers can be loaded onto a single
SF-16M amplier output.

Speaker Impedance 8Ω 6Ω 4Ω

Max # of speakers per SF-16 amp output 3 2 1

Figure 7 - Wiring multiple speakers per amplier output.

NOTE: this table assumes that all speakers on a single channel
are of the same impedance and are connected in parallel. If you
wish to mix a combination of speakers with different impedances
on one channel it will be crucial to use an impedance calculator.
Please visit the SF-16M product page at audioauthority.com to use
our online SF-16M impedance calculator. In all cases, it is impera­tive that total speaker impedance for any one channel does not go
below 4 Ohms.

SF-16M. If the router is also DHCP enabled, it will automatically assign a unique network IP address to the SF-16M.
Once an IP address is assigned, the SF-16M can be setup and controlled with any network-enabled control system using
telnet-based serial commands. For detailed information on ethernet setup, please see page 19. Communication is 2-way
which allows for control as well as feedback to the control system. Again, a list of available serial commands is available
for download on the SF-16M product page of our website.

The SF-16M provides two “Audio Override” contact closure inputs, which allow pushbuttons, partition wall contacts, and
other contact sensors to trigger the system. Audio override provides a convienent method of temporarily switching to an
alternate audio input when a sensor is triggered.

A practical example of this feature is a conference hall with movable partition walls. See Figure 12. When the partition
closes to create individual rooms, a partition wall contact closure (Override 2 in the example) triggers the SF-16M to
switch to a microphone input located in one partion area. When the partition wall opens, the SF-16M returns to its default
audio input. Override 1 can trigger the same behavior or a different behavior.

SF-16M CONNECTIONS - System Trigger (5V-24V AC/DC)

The System Trigger input on the SF-16M allows equipment such as AV receivers or power managment devices to put the
SF-16M in standby when not in use, thereby greatly conserving energy usage.

To enable the System Trigger:

1. Make system trigger connections as illustrated in Figure 13.

2. Power the SF-16M, then apply power to the triggering device.

3. Using the front panel menu (see page 17) or the PC congurator, enable “System Trigger”

CONFIGURATION

Basic conguration of the SF-16M can be achieved using the front panel controls. It is possible to congure all settings on
the SF-16M via telnet/serial commands with a program such as hyperterminal on your PC (page 18).

The recommended method to perform advanced setup tasks is to use the SF-16M PC conguration software,
available for download on the SF-16M product page at audioauthority.com. In addition to being more efcient, project
les can be saved to your PC for backup and future modication. Detailed instructions for SF-16M setup using the PC
conguration software are included with the software download.

Advanced Conguration

The following settings cannot be congured using front panel controls:

1. Output Groups - Group multiple outputs together to share source selection, volume up/down, mute on/off, and power
on/off commands. Groups are ideal for making large areas act like a single audio zone or for grouping outputs with hi­pass and low-pass lters (sub/sat combinations) so that they respond together. Group specic serial and IR commands
are available for source selection, volume up/down, mute on/off and power on/off. Up to 10 groups can be stored per SF­16M. Group settings include group naming and output members.

2. Audio Override - The purpose of audio override is to provide a convenient method of temporarily switching a pre­dened group of outputs to a specic input. Once the audio override is completed the outputs effected by the override
return to their previous input and volume levels. Typical examples of audio override include paging, doorbell tones and
local source selection for in-room sources such as iPods and audio mixers. Audio override can be triggered by two
contact closure inputs on the back of the SF-16M, as well as specic serial and IR commands. Up to 10 audio override
congurations can be set up per SF-16M. Audio override settings include input assignment, output members, output
levels, override priority and momentary or toggle mode for the audio override contact closures.

3. Sound Scenes - A sound scene is a system-wide snap shot of all volume levels and input assignments. Scenes
allow the end-user to recall previously captured system settings with a single button press. Up to 10 sound scenes can
be saved and recalled per SF-16M. Scenes can also be saved and recalled across multiple SF-16M’s linked together,
however each individual SF-16M has a maximum of 10 unit or “global” scenes. Scene settings include scene naming,
input selection, output levels, mute status and an “Ignore” option which allows a outputs to always ignore a scene preset.

4. EQ lters - Up to seven EQ lters can be applied per SF-16M output, including hi-pass/low-pass, hi-shelf/low-shelf or
seven-band parametric EQ. Parametric EQ can be used in combination with the other EQ lters.

5. Input/Output Naming

6. Network/IP Conguration

PDF User Manual

Follow the instructions for your Control4, RTI, URC, or other controller using the serial settings below, and/or Ethernet
settings accessible via the SF-16M front panel menu. Serial commands, available at our website on the SF-16M product
page, are used via telnet or serial connection.

The SF-16M telnet server allows two clients to be connected at one time. Each client connection has a time out of 15

minutes; if a client crashes and does not close the connection properly (sending an EOF) that connection remains
busy until it times out.

Using the RS-232 Port

System controllers and PCs send all setup and control commands as well as receive feedback via the RS-232 serial port.

• Important: If a PC is connected directly to the SF-16M RS-232 port, use a standard serial cable.

• Communication Settings: baud rate is 9600 bps, 8 data bits, no parity, 1 stop bit, and no ow control.

• See the table and diagram below for the SF-16M serial port pinout.

Using a PC via Ethernet

Connect a computer directly to the SF-16M Ethernet port using a crossover cable, or alternatively use a standard Ethernet
hub or switch and a standard patch cable. Once connected to a computer or network, the SF-16M by default attempts to
obtain an IP address automatically using DHCP. To use static settings, see the detailed instructions on page 19.

There are two LED indicators located next to the Ethernet port on the rear panel that will help in
identifying connection issues:

• Link - The Link LED is steadily lit if a connection is detected and ashes when activity is
present.

• Speed - The Speed LED is off for 10 base T, and on for 100 base T.

ETHERNET

LINK

SPEED

16M rear panel

DHCP

DHCP is enabled on the SF-16M by default. If DHCP is enabled on your network, simply connecting the SF-16M to the

network with an existing DHCP server enables it to obtain all necessary information.

Static Addressing Connected Directly to a PC

The SF-16M must be given an IP address which will not conict with the PC.
Go to the network settings (which are found in control panel -> network -> local
connection properties of a PC running Windows XP).

Change the TCP/IP protocol properties, and set the IP address, gateway, and
subnet mask, if they are not already set.

18 SF-16M Matrix Amplier Installation and Operation Guide

SF-16M screen image showing Network
Settings with DHCP set to ON, with no link
established.

This can be arbitrarily done on a direct connection, but a good choice for the settings would be IP address of 192.168.0.1,
subnet mask of 255.255.255.0, and an empty default gateway. Once these values have been set, use serial commands
to set the network settings of the SF-16M in a similar manner, but use a different IP address than that of the computer (for
example, 192.168.0.2).

Static Addressing on a Network

The SF-16M must be set to the same settings as the PC except for the IP address, which must be one available on the
network. To determine this in Windows, use the DOS prompt (Start->Run->cmd) commands ipcong and ping. Ipcong
will list the PC’s settings, and ping will allow you to test addresses to make sure that nothing else on the network has that
address. Enlist the help of a network administrator if you are unfamiliar with setting up a network connection.

Once a connection is established, a telnet program such as Hyper Terminal, Teraterm, PuTTY etc, must be used to
connect to the device. Enter the IP address of the SF-16M and leave the default port (23) to connect. Once connected,
standard serial commands can be issued in an identical manner to serial control.

Using an IR Control System

The SF-16M uses a three wire IR circuit. It is imperative that the correct polarity be maintained when connecting third
party IR equipment. The 3.5MM pinout is shown in the illustration below. Connect the IR signal from your IR controller
directly to the main IR input port on the rear panel. Alternatively, adhere an IR emitter from your infrared system onto the
SF-16M front panel receiver.

If the SF-16M IR codes are available from your remote control company, download and/or activate those les. A CCF le
containing the latest codes can be downloaded from our website on the SF-16M product page.

Tips for Using Infrared Control

• If you are using standard hand-held IR remote controls, ensure correct
operation by avoiding sources of light pollution such as Plasma and
LCD TVs, direct sunlight, uorescent light, etc. Experiment with the
physical placement of the IR receiver to avoid interference.

• If a source of interference cannot be eliminated or avoided, use IR
receivers that block that type of interference, such as Plasma-proof or
LCD-proof receivers.

FlexPort audio modules provide up to four additional audio inputs (2 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. All 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.

FlexPort Module “Override” Button

The purpose of the front panel override button is to switch designated SF-16M outputs to a FPM input. A typical example
is an audio mixer, connected to a FPM-X in a conference room. When the override button is pressed, designated outputs
will switch over to the audio mixer for the duration of the override. When the override button is pressed again, all effected
outputs will switch back to the input source prior to override. Audio override is based on two key settings:

1. FPM dipswitch settings, previously congured above.

2. SF-16M audio override settings, programmed using the SF-16M PC conguration software (see page 14 or view the PC
conguration software manual for more information on audio override settings).

Audio Override with “Mix” Option Enabled

In some cases it may be desired to mix two FPM
module inputs together upon audio override. An

example would be a classroom where both a
microphone and an audio presentation need to be

heard simultaneously. To acheive this function, rst
daisy chain two FPM modules and wire back to the
SF-16M. Set one FPM as “Mono 1”, and set the
other as “Mono 2”. Both FPM’s must have the

“Mix”

dipswitch set to On.

4. Follow the prompts and select the rmware le.

5. After a short delay the SF-16M reboots and performs the rmware update.

6. Once the update has nished, the SF-16M reboots and resumes operation with the new rmware version.

Appendix C: SF-16M Rack Mounting

The SF-16M is designed so that it may be installed either on a shelf or
in a standard 19-inch equipment rack. If rack mounting, remove the
feet and the cover screws adjacent to the front panel of the unit. Reuse
the cover screws to mount the rack adapters supplied with the SF-16M.
Be sure to place a spacer under the adapters at every screw location.
Secure the SF-16M to the rails of the equipment rack with the screws
supplied, and use appropriate chassis supports, such as Middle Atlantic
CSA Series.
