The BOZ 216/2200 redefines amplification. The digital input is taken to the central processor where it is
reformatted into a pulse width modulated signal of extreme precision. The pulse rate is measured at precisely
384,000 pulses per second. Each pulse can have 256 different widths, with the narrowest pulse being a mere
100 millionths of a second wide. The clock frequency therefore is 98 MHz. The central processor computes
exactly the right combination of pulse widths to produce an incredibly accurate waveform.
Once the decision of the duration of the pulse is made, the central processor controls FET-switches at the out
put with extreme precision. Voltage and current are drawn from the power supply and are fed to the speakers.
The level of playback is controlled by adjusting the voltage of the power supply. As this voltage is switched di
rectly to the speakers, it is of paramount importance that the power supply be totally free of ripple and noise.
For BOZ digital amplifiers, a switch mode power supply of extreme precision with ripple rejection of more
than 135 dB has been developed. At full volume the BOZ 216/2200 delivers 200 Watts into 8 ohms. To reduce
the volume the voltage of the power supply is reduced. This means that the volume control is no longer part
of an active circuit.
Exclusive technology
The most fundamental departure from conventional amplifiers is that the BOZ 216/2200 defines the waveform mathematically - it does not try to follow or emulate a waveform by using feedback or feed-forward.
So why hasn’t anybody thought of this before? Why has this not been done before? Well, try to switch more
than 60 volts DC 384,000 times per second without creating even a whisper of noise at a distance of 1” from
the tweeter! Only in the past few years has it been possible to create a fully digital “amplifier”.

boz line introduction
The Tact Millennium
Tact Audio introduced the Tact Millennium, the world’s first true digital amplifier, back in 1998. It
was not only heralded as the most important technological breakthrough in decades, it was also
immediately recognized as the greatest sonic improvement in amplification ever.
The audio press was unanimous in its praise: “Without any true competition,” “It sounded much
more like live music than anything else I had heard,” and “Overwhelming transparency,” were
among the words of praise.
The M2150 & S2150
In 2002 Tact Audio introduced the second series of digital amplifiers, the M/S-2150. Until the arrival
of the M/S-2150 series, no other digital amplifier came anywhere near the performance level of the
Tact Millennium.
The M/S-2150 series amplifiers were designed in a more efficient way than the Millennium. They
also feature major improvements in the digital signal processing section. Continuous research
and development as well as advancements in technology have allowed us to reduce prices while
maintaining quality. The significant improvements in the layout and digital design ensured that
the 2150 reached a new level of excellence and became the world’s best selling true digital power
amplifier.
The Boz Line
With the 2005 introduction of the BOZ line of digital amplifiers, Tact Audio offers the world’s first
multi-channel digital amplifier with performance exceeding that of its predecessors, the Tact Millennium and Tact M/S-2150. The first product of the BOZ line is the BOZ 216/2200 true 16-channel
digital amplifier.
The BOZ design is based on a separate power entry and control module, the BOZ-216 (referred to
as the BOZ-216 control unit), combined with two channel power amplifier modules, the BOZ-2200
(refereed to as amplifier modules). The BOZ-216 control unit can handle up to 8 BOZ-2200 modules
for a total of 16 channels of amplification.
The Tact Millennium
was awarded the
prestigious
iF Design Award in
2001
www.ifdesign.de
The TacT M2150 was
awarded the Stereotimes Most Wanted
Component Award
for three consecutive
years: 2003, 2004, and
2005.

The BOZ 216/2200
was awarded the Stereotimes Most Wanted
Component Award for
2005 - a mere month
after its initial release.
www.stereotimes.com
The input AC power connects to the BOZ-216 control unit via two power entry modules. The
power entry modules each have built in line filtering. Each power entry module can handle up to
1250 W of power. Both power entry modules combined together can deliver 2500 W of power. In
this way twelve amplifier channels can simultaneously deliver 200 W of power.
While preserving the core design philosophy of the Tact Millennium and the Tact M/S-2150, the
new BOZ 216/2200 amplifier is designed with the latest in digital signal processing technology.
Special attention has been paid to board design and signal distribution between the modules
inside the BOZ-2200. All digital audio signal routing is implemented with differential LVDS logic
design. In order to further reduce system jitter the previously existing phase locked loops (as in the
Millennium and M/S-2150) are completely eliminated.
characteristics of the ‘boz’ line
Mono Block Design
Each amplification channel in the BOZ-2200 is self contained with a separate processor-controlled
power supply and a PWM circuit.
Floating Point Processing
High precision floating point processing. All real time audio signal processing algorithms are implemented with floating point arithmetic.
LVDS (Low Voltage Differential Signaling)
All digital audio signals in the BOZ-2200 are routed with LVDS (low-voltage differential signaling)
drivers/receivers. This design ensures maximum signal integrity for all digital audio signals.
External Clock
Each BOZ-2200 can accept an external clock for jitter-less reception of AES/EBU and SPDIF signals.

Crossover Package
The crossover package running on the BOZ-216 control unit does not require computer support to
implement Butterworth and Butterworth squared filters. The crossover package supports:
1. Low-pass filters
2. High-pass filters
3. Band-pass filters
The above are supported with a filter cutoff frequency anywhere between 15 Hz and 24000 Hz
with filter slopes from 1-st to 12-th order.
Parametric Equalization package
The parametric equalizer package features 12-band parametric equalization per channel and ten
presets per channel. The ParEq specs are:
1. Filter center frequency between 15Hz and 24000Hz
2. Filter level adjustment from -18.0 dB to +12 dB in increments of 0.1 dB
3. Filter bandwidth from 0.01 to 2.5 octaves
Room Correction Package
The room correction package running on the BOZ-216 control unit is assessable directly from the
front panel. Front panel access lets you choose between 10 preset correction settings. The correction settings are loaded to the unit via the provided RS232 cable. The room correction technology
utilized in the BOZ line is derived from the award winning room correction technology of the
original Tact Audio RCS product line.
Multi Zone Support
Multi zone support - we call them groups. There are in total 9 groups. Eight groups are user configurable and the ninth group has all amplifiers assigned to it automatically. Each group can consist
of any combination of the eight amplifiers. Master volume control will control the volume of the
selected group only. If ALL is selected, then the volume control will affect amplifiers modules in
each group.

The Boz 216/2200 is not Really an Amplifier
The BOZ 216/2200 is not an amplifier at all. No signal amplification takes place whatsoever!
The BOZ-2200 modules are an ultra high precision D/A converters operating in PWM mode with a
master clock set at a speed 2,222 times higher than the CD format, 1,024 times higher than DVDAudio and 35 times higher than the SACD format. In contrast to conventional D/A converters, it
operates at a switching voltage of more than 60 Volts, delivering the equivalent of 400 Watts per
channel in 4 Ohms. All internal signal processing is performed at 96Kz
Conventional Amplification vs. Boz Amplification
The entire active analog signal path consists of a single coil and a single capacitor, forming a 12 dB
per octave low-pass filter at 70 kHz. The voltage of the power supply determines the output level,
thus eliminating the need for any passive volume control.
Compared to a normal amplification chain this is a massive reduction in complexity. In a normal
chain, the output of the D/A converter is sent to an analog buffer stage, then to an analog pre
amplifier with relays, input stage, volume stage and output stage. It is then sent as a low-voltage
analog signal to the power amplifier with an input stage, output stage and feedback loop. Finally,
the signal is sent to the speakers.
-
In a conventional amplifier, all of this complex and costly circuitry requires hundreds of compo
nents. The BOZ 216/2200 digital amplifier replaces all this with just two components.
Added Benefits of the Boz System
In addition to the revolutionary amplifier design, the BOZ Series is equipped with the latest 192
kHz sample rate conversion technology at the digital inputs. All digital audio signal routing is performed by using LVDS logic for maximum signal integrity. All audio signal processing algorithms
are implemented with floating point precision.
Your BOZ-216 control unit achieves total separation of the input AC power from the sensitive and
extremely clean digital audio signals in the BOZ-2200 modules. Inherent to this setup is unparal
leled system-wide noise reduction and maximum signal purity.

technological advantages
High Resolution at Normal Listening Levels
High resolution at normal listening levels: With a normal amplification chain, resolution is dependent on the volume setting. The power amp is always on maximum level - even when listening at
low levels. In most cases, only the highest level of playback will give full resolution.
In the Boz amps, the playback level is controlled by the voltage of the power supply. At low levels,
the supply is at low voltage but the signal remains identical. Starting at a level of 30 dB below
maximum, DSP-controlled digital attenuation takes over. This is done with extreme precision using
floating point arithmetic.
No Feedback
Feedback in normal amplifiers is known to cause ringing in the time domain. The BOZ-2200 approach uses no feedback or feed-forward in the signal path.
Immunity to Loudspeaker back-EMF
Total immunity to loudspeaker back-EMF: Any loudspeaker driven by an amplifier will send current
back into the amplifier. This can make the amplifier behave in mysterious ways as it interacts with
the feedback loops. But with the BOZ digital amplifier, zero feedback and steady-state voltage from
the power supply means that back-EMF can have absolutely no effect on the sound.

boz introductionboz introduction
Inherently Free From Ringing
Music is all transients, very few instruments produce anything that resembles pure sine waves.
Conventional amplifiers will overshoot and undershoot transients to varying degrees – simply
because transients are voltage swings. In the BOZ digital amplifier, the signal is determined by the
timing of the switching, while the voltage remains constant. Time cannot resonate and when voltage remains constant, there is no risk at all that the design will produce any ringing.
Low Heat
BOZ digital amplifiers produce far less heat per W/cubic inch than conventional amplifiers. This will
extend the product’s lifetime considerably. The elimination of a mechanical volume control and
relays adds further to the lifetime of the product and ensures that no sonic degradation will take
place over time.
Lowest Ever Power Supply Noise Floor
The power supply has been designed with triple-stage supply noise suppression. The noise floor is
at -135 dB. This is far below the level for any known power conditioning equipment in the industry.
Modular Design
The BOZ system is the epitome of modular efficiency: you decide how many channels of amplification you need and you specify your system accordingly. Optional system features, such as the
Crossover, Room Correction, and Parametric Equalization packages, are also designed with flexibility in mind. All software can be easily added to your system at any time. Modular DSP design also
allows us to provide you with firmware upgrades that you can easily download and install.

example is for a Boz
system that consists
of two BOZ-2200
amplification modules,
for a total of four channels of amplification.
Connection procedures
for systems that
consist of additional
BOZ-2200 modules are
easily extrapolated.
Always turn the power off first before making any new connections or changes to existing connections.
Power-off by using the BOZ-216 main power switch and then disconnect the two supplied AC power
cords from the wall power outlet. When connections or changes to the existing connections are completed, plug the AC power cords into the wall outlet and then turn the main BOZ-216 power switch on.
