RCA Line Inputs

The SF-16M includes 16 RCA audio inputs that can be congured as mono, stereo or a
combination of both mono and stereo. Figure 1 shown below provides examples of all
congurations. NOTE: It is important that all physical input congurations are entered into the

SF-16M programming, using the PC conguration software or the front panel system menu.

Note: to create a mono

DB-25 Audio Connections

SF-16M units may be linked together to create systems up to 32 inputs x 64 outputs (see p. 13 for hookup details). The
DB-25 ports streamline this type of expanstion, and also serve as a connection from Audio Authority matrix systems.

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: For installations 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).

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 congurations, 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 conguration.

Speakers and Impedance

Each ampler output of the SF-16M can support a 4 Ohm speaker
load. In many cases only one speaker is connected per amplier
output, so any single speaker with a 4 - 8 Ohm impedance rating
is acceptable for use with the SF-16M. Two 8 ohm speakers
can be connected in parallel onto a single SF-16M amplier
output without sacricing performance (Figure 7). Do not connect
multiple 6 ohm or 4 ohm speakers to one SF-16M output, and do
not connect multiple speakers wired in series.

Ferrite Beads

If System Trigger or Override terminals are used, attach a ferrite bead
around the wires near the terminal. Apply a separate ferrite bead to
override and system trigger wires.

Changing the Power Fuse

Before changing the fuse, nd and correct
the excessive impedance load or wiring
short that caused the fuse failure.

The fuse compartment contains two extra
fuses that can be used to replace blown
fuses in the eld. Access the replacement
fuses by sliding out a compartment behind
each fuse, as shown in Figure 7.

• Remove the power cord

• Use a at head screwdriver to remove the
fuse cover

• Inspect both fuses to determine which

Ethernet Port

The Ethernet port of the SF-16M connects to any standard ethernet router/switch. By default DHCP is enabled on the
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

PDF User Manual

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 convenient 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 (Figure 12). The speakers in the room
normally play background music from a satellite radio receiver. A pushbutton triggers Override 1 which is programmed to
toggle speaker outputs for both rooms between background music and the Microphone 1 input. When the partition closes
to create individual rooms, a partition wall contact closure (Override 2 in the example) triggers the SF-16M to switch the
speakers in Room B to microphone 2. When the partition wall opens, the SF-16M returns to its default audio input.

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 can be congured using Ethernet/serial commands or the PC setup utility (not 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 pre-

de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 any output to always ignore a scene preset.

4. EQ Filters - 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

Front Panel Menu Options

Output Settings > Quick Access

The Output Quick Access screen provides a “snap-shot” of key settings and the ability to adjust parameters for each
setting. To begin, select the output you wish to view. Turn the knob and push to adjust any parameter. Output settings
and descriptions are listed below:

• Output Number/Name:

In this case, “Billiards” is a stereo output comprised of outputs 9 and 10.

• Volume: B This line shows volume level, or other status messages:

1. Volume - The output level, a range from -80 up to 0 dB attenuation. Adjustable by

a discrete value or using a volume up or down command. 1 dB increments in the

-40 to 0 dB range, and 2 dB increments in the -80 to -40 range.

2. Standby - The SF-16M is in a power saving mode, which is triggered by issuing a

standby command or using the back panel trigger. Affects all outputs.

3. Shutdown - Shutdown means the output cannot come on because of a short on

the output, overheating of the output (impedance too low), or hardware failure.

4. Overtemp - The output is off due to too high a temperature of output chips. This can be caused by a speaker

impedance that is too low or inadequate ventilation.

5. Poweroff - Power off mode (similar to mute) is set by the user. When power is turned on the output volume level is

set to the previous level, within the maximum turn on and minimum turn on levels.

6. Muted - The output is muted, which silences the output temporarily. Unmute restores previous volume levels.

7. Automute - No input signals are detected for any of the 8 outputs in the output bank. Output banks 1-8 and 9-16 are

separate, so if no audio is present on selected inputs to an output bank, the outputs automute.

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 for telnet or serial control.

The internal 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 command) 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.

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.

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

Assign an IP address to the SF-16M which will not conict with the PC.

• Windows 7: Control Panel -> Network and Sharing Center > Change adapter
settings > Local Area Connection (or wi- adapter) > Details

• Windows XP: control panel > network > local connection properties

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

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 two 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 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).

761-391

Audio Override with “Mix” Option Enabled

In some cases it may be desired to mix two FPM

BUS IN

module inputs together upon audio override.
An example would be a classroom where both
a microphone and an audio presentation need

BUS OUT

™

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.

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.
