SF-16M Matrix Amplifier Installation and Operation Guide 7
INTRODUCTION
The SonaFlex™ SF-16M is a unique blend of premium, multi-channel amplification, flexible input options,
audio matrix switching, signal processing, and open control capability. Built and designed in the U.S. with
AV integrators in mind, the SF-16M offers a new approach to commercial and residential distributed audio
applications. This manual covers basic and some advanced topics, but you can find more articles and video
at www.audioauthority.com/sonaflex_tips.
Key Features
• Input matrix switching, signal processing and amplification in one unified system
• 16 analog RCA inputs, plus two FlexPort™ inputs (two channels each) for a total of 20 mono (10 stereo) inputs
• Optional Cat 5 FlexPort audio transmitters accept balanced line/mic, XLR, digital SPDIF, or analog RCA audio
• 16 amplified outputs can be configured as mono, stereo or a combination of stereo and mono
• Up to four SF-16M units can be linked together to form a 64-output audio matrix (see p. 15)
• Class-D amplification provides a conservatively rated 50 watts per channel,
all channels driven
into 8 Ohms - stable at
4 Ohms
• Linear power supply delivers the warmth and musicality of an analog amplifier, combined with the responsiveness and
headroom required for dynamic music content
• Signal processing tools include hi and low shelf filters (bass/treble), hi and low pass filters 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 output “groups” allow multiple outputs to share commands like volume ramping, muting, and source selection
• Compatible with virtually any control system using RS-232, Ethernet, or IR commands
• Commonly used settings are accessible via the front panel controls and VFD display; advanced setup is performed via
the PC configuration utility* or Ethernet/serial commands (see page 24)
• Power saving features include automute and turn off per output channel, and a system trigger input so that power
management devices can put the SF-16M in standby when not in use
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 flexibility in audio source placement
Control Interfaces
• Ethernet via telnet commands (see page 24)
• RS-232 serial commands (see page 25)
• Two contact closure inputs to trigger audio overrides and sound scenes (page 14)
• Rear panel IR input (3.5 mm jack)
• Front panel IR sensor
• Front panel capacitive touch buttons and knob with vaccuum fluorescent screen
