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.
