INTRODUCTION
The SonaFlex SF-16M is a unique blend of multi-channel amplication, exible input options, audio matrix switching,
signal processing and open control capability. Built and designed in the U.S. with sound and video integrators in mind, the
SF-16M brings a new approach to common commercial and residential distributed audio applications - one multi-purpose
matrix amplier that can be used in a variety of installations.
Key Features
• Audio matrix switching, signal processing and amplication in one unied system
• 16 analog RCA inputs combined with 2 Cat 5 “FlexPort” inputs allow for a total 20 mono/10 stereo inputs
• Optional Cat 5 FlexPort audio modules accept balanced line/mic, XLR, digital SPDIF and analog RCA audio sources
• 16 amplied outputs can be congured as mono, stereo or a combination of stereo and mono
• Up to four SF-16M units can be linked together to form a powerful 32 input x 64 output audio matrix
• Class-D amplication provides a conservatively rated 45 watts per channel (all channels driven) or 60 watts (8
channels driven) at 8 Ohms - stable to 2 Ohms
• Linear power supply delivers the warmth and musicality of an analog amplier, combined with the responsiveness and
headroom required for dynamic music content
• Signal processing tools include hi and low shelf lters (Bass/Treble), hi and low pass lters and up to seven bands of
parametric equalization per output
• 10 preset sound scenes, a system-wide snap-shot of all volume and source settings, can be saved and recalled using
IR, RS-232 or IP commands
• 10 audio groups allow multiple outputs to be grouped together to share volume ramping, muting, source selection and
more
• Compatible with virtually any control system available today using RS-232, Ethernet or IR commands
• Front panel VFD display allows for access to commonly used settings - PC congurator, available for download,
allows for more advanced setup
FlexPort Cat 5 Audio Inputs
• Four compatible FlexPort audio modules: FPM-U Stereo RCA, FPM-D Digital Coax/Optical Audio, FPM-X Mic/ 1/4” TRS
Audio and FPM-B Balanced Audio (See Appendix A for detailed information)
• Provides a mixture of consumer and pro audio sources such as MP3 players, audio streaming devices, microphones,
audio mixers, paging microphones and more
• FlexPort modules can be located up to 500 feet away from the SF-16M giving exibility in audio source placement
Control Interfaces
• Ethernet
• RS-232 Serial
• 2 contact closure inputs to trigger audio overrides and scenes
• Rear panel IR input (3.5 mm jack)
• Front panel IR sensor
• Front panel capacitive touch buttons and knob with LCD screen

The SF-16M includes 16 RCA audio inputs that can be congured as mono, stereo or a combination of both mono and
stereo. Figure 1 shown below provides examples of all congurations.
NOTE: It is important that all physical input congurations are entered into the SF-16M programming, using the PC conguration software or the front panel system menu.

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 amplier 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 amplied outputs. The HLX or ADX provides all of the matrix switching (See gure 3 below).
