FIXED RANGE

Pure, Stable and Reliable Power

Using Class-D digital ampliﬁcation, the SF-16M produces

a conservatively rated 45 watts per channel (all channels

driven) or 60 watts (8 channels driven) at 8 Ohms and is

stable to 2 Ohms. The SF-16M is so rock-solid that even a

dead short to the outputs won’t negatively affect the unit.

The SF-16M shuts off the ampliﬁer stage until the short is

corrected and then comes back on without a power cycle.

Dynamic Range Extends Response

Quite possibly the most impressive beneﬁt of the SF-16M is

its dynamic audio quality. Competing Class-D products use

switching power supplies, which are efﬁcient, but have a

serious ﬂaw: they can’t manage large transient peaks, result-

ing in audio distortion. The SF-16M hybrid linear supply has

the headroom to respond to musical dynamics with extra

power, because its analog design allows its ﬂoating voltage

rail to accommodate quick transient peaks in the music,

instead of clipping, like the switching supply does. The result

is vibrant, accurate sound reproduction that your clients will

enjoy and value.

Quality Front-End Components

The SF-16M features 24-Bit, 96-kHz Burr-Brown A/D conver-

sion with 64-times oversampling, resulting in natural,

acurate sound reproduction of the input source material.

Signal Processing Tools

The SF-16M provides a rich palette of Digital Signal Process-

ing (DSP) tools that allow the installer to custom-tune

every sonic environment. For basic installations, use the

DSP’s bass, treble, balance and loudness controls. For more

advanced applications, use hi/low pass ﬁlters and up to

7-bands of parametric equalization per output.

Pass-Thru Mode

When you need a great sounding amp to use with an

existing audio matrix, the SF-16M still shines, providing 16

RCA inputs and DB-25 source audio loop outputs for system

expansion. In addition, the SF-16M’s DB-25 input allows for

quick connection to Audio Authority audio matrix switchers

such as HLX and ADX. The built-in FlexPort audio inputs can

still be used in pass-thru mode to override any on-board RCA

audio input, enabling features such as local source selection,

paging override, doorbell override, and room combining.
