4 SF-16B Digital Amplier Installation and Operation Guide
INTRODUCTION
The SonaFlex SF-16B combines an innovative digital amplier design with a rock solid linear power supply to yield
musicality and power like no other amp in its class. It is the basic version of the SF-16M, a matrix amplier with many
other advanced features, but the basic version has all the musicality and headroom that makes the SonaFlex series
popular with audiophiles. Built and designed in the U.S. with sound and video integrators in mind, the SF-16B offers
simple path to high delity amplication for commercial and residential distributed audio applications with or without a
matrix preamplier.
Key Features
• 16 analog RCA inputs that can operate 1:1 (usually with a matrix preamp) or in bus mode (all outputs on inputs 1,2).
• Class-D amplication provides a conservatively rated 45 watts per channel (all channels driven) or 60 watts (8
channels driven) at 8 Ohms - stable to 4 Ohms.
• Linear power supply delivers the warmth and musicality of an analog amplier, combined with the responsiveness and
headroom required for dynamic music content.
• Power saving features include automute and a system trigger input so that power management devices can put the
SF-16B in standby when not in use.
Carton Contents
• SF-16B 16-Channel Amplier
• Power Cord
• DB-25 cable (see page 8)
• Rack ears (see page 22)
• User manual
Other Materials You May Need
• Speakers and cabling

• RCA patch cables
BEFORE YOU BEGIN
• Conrm that nothing is missing from your shipping carton. Refer to Carton Contents above.
• Record the serial number (see rear panel) in the space provided inside the cover of this manual for easy reference.
• Activate your warranty and receive rmware update notications by registering at www.audioauthority.com/register.
• Read this instruction manual to become familiar with the congurations and functions of this product.
BASIC SETUP TASKS
1. Thoroughly plan your system layout including wire runs, audio inputs and speaker locations.
2. Mount the SF-16B in an equipment rack; pull and label all audio and control cabling.
3. Connect audio sources to SF-16B input(s) and speakers to amplied outputs of the SF-16B.
4. Set Turn On Mode and Bus Mode and connect Trigger if desired.
4. Test all audio inputs at all speaker locations.
SF-16B Digital Amplier Installation and Operation Guide 5
Quick connect audio inputs and loop outputs via
DB-25 connector. This connection is ideal for
connecting multiple SF-16B units to share the
same input(s) or for use with ADX and HLX matrix
preamps.
RCA audio inputs with gain adjustment per stereo
pair. Input A is the Bus Input when Bus Input is on
(E).
Stereo speaker-level Outputs.
System Trigger In & Out (5V - 24V AC / DC). Trigger
output may be connected to additional SF-16B or
other equipment.
Feature switches 1 and 2. Switch 1 sets Trigger
Mode or Always On mode. Switch 2 sets Bus Input
for use with one source, or 1:1 Inputs, individual
inputs for each output, for use with matrix preamp.

SF-16B CONNECTIONS - Speaker Outputs
Speaker Outputs
Connect speakers to removable speaker terminals using appropriate
gauge speaker wire. Speakers may be installed while the amplier is
playing. The SF-16B shuts down any output that has a dead short until
the short is cleared. The output comes back on with no reset necessary.
Speakers and Impedance
Each ampler output of the SF-16B 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-16B. Two 8 ohm speakers can be connected
in parallel onto a single SF-16B amplier output without sacricing
performance (Figure 7). Do not connect multiple 6 ohm or 4 ohm
speakers to one SF-16B output, and do not connect multiple speakers
wired in series.

RCA Line Inputs
The SF-16B includes 16 RCA audio inputs in
stereo pairs, and as an alternative, a quick
connect input using a DB-25 cable. If used with
a matrix preamp, all inputs correspond to like
numbered outputs, and 1:1 Input setting should
be used. If used with a single source or with
a switch, use Bus Input setting, and connect
Input A (1 and 2) only.
2. Input from an Audio Authority audio matrix:
For installations where the SF-16B is serving as an
amplier for Audio Authority audio matrix preampliers
such as the ADX-0808, ADX-1616 (Figure 4) or the
HLX with 2278 audio output card (Figure 5).
In these congurations, the SF-16B receives all audio
content from the ADX or HLX and passes the audio
through to the corresponding amplied outputs. The
HLX or ADX provides matrix switching, volume control,
equalization, tone and balance.
One ADX-1616 supports two SF-16B ampliers, and
the HLX platform can be congured to support up to
twelve SF-16B amps, one for each audio output card.
SF-16B Digital Amplier Installation and Operation Guide 7
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 9.
• Remove the power cord.
• Carefully remove the fuse cover using a
at blade screwdriver.
• Inspect both fuses to determine which
one is blown.
• Replace the blown fuse with a spare fuse,
or a fuse of the same value.
• Orient the fuse cover so that the arrow
points toward the correct voltage for your
region as shown in Figure 9.

SF-16B CONNECTIONS - System Trigger
(5V-24V AC/DC)
The System Trigger input on the SF-16B allows equipment such
as AV receivers or power managment devices to put the SF-16B 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-16B, then apply power to the triggering device.
3. Set System Trigger DIP switch in the up (TRIGGER MODE)
position.

SF-16B Rack Mounting
The SF-16B 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-16B. Be sure to place a spacer under the adapters at every
screw location. Secure the SF-16B to the rails of the equipment
rack with the screws supplied, and use appropriate chassis
supports, such as Middle Atlantic CSA Series.
