4      SF-16B Digital Amplifier Installation and Operation Guide

INTRODUCTION

The SonaFlex SF-16B combines an innovative digital amplifier 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 amplifier 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 fidelity amplification for commercial and residential distributed audio applications with or without a 

matrix preamplifier.

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 amplification 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 amplifier, 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.
