Congratulations on your purchase of your M/S 2150. You have now acquired the most advanced stereo amplifier ever developed!

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 10 nanoseconds wide. The clock frequency therefore is 98 MHz. The central processor uses proprietary patented algorithms (Equibit) to arrive at exactly the right combination of pulse widths produce a highly accurate waveform. This is the most fundamental departure from conventional am- plifiers. TacT defines the waveform mathematically - we are not trying to follow or emulate a waveform by using feedback or feed-forward.

Once the decision of the duration of the pulse is made the central processor con- trols FET-switches at the output with extreme precision. Voltage and current are drawn from the power supply and fed to the speakers.

The level of playback is controlled by adjusting the voltage of the power supply. As this voltage is switched directly to the speakers, it is of paramount importance that the power supply be totally free of ripple and noise. For TacT digital amplifiers, a switch mode power supply of extreme precision with ripple rejection of more than 135 dB has been developed. At full volume (voltage) the TacT M/S2150 delivers 58 volts, equivalent to 150 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.

Why has this not been done before? - Well, try to switch 58 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”.

-Ultra high precision DA conversion

-Upsampling to 384,000 Hz before conversion

-Full resolution at -30 dB

-Software upgradeable DSP section

-DSP-based 48 bit internal electronic crossover (in bi-amped mode)

-192kHz/24bit AD converter

-Digital pre-amplification with 24-bit resolution at a playback level of -39 dB!

-Output of 2x300W into 4 Ohm load, with extreme load tolerance

-NO feedback or feedforward locally or globally is utilized in the signal path

M2150, S2150 specifications

TacT Audio is a prominent player in the high-fidelity audio equipment market, known for its innovative digital amplification technologies. Among its flagship products are the S2150 and M2150 amplifiers, both of which embody the brand's commitment to superior sound quality and cutting-edge design.

The TacT Audio S2150 is a stereo amplifier that exemplifies the company's philosophy of delivering high-performance audio reproduction. With its Class D amplification technology, the S2150 offers exceptional efficiency and low heat generation, making it suitable for long listening sessions without the risk of overheating. It boasts an output power of 150 watts per channel into 8 ohms, delivering dynamic and powerful sound that can drive a wide range of loudspeakers effectively.

One of the standout features of the S2150 is its built-in digital signal processing (DSP) capabilities. This allows for precise room correction, enabling users to optimize their listening environment for the best possible audio experience. The user-friendly interface makes it easy to adjust settings for different room acoustics, ensuring that music is reproduced with clarity and precision.

The M2150, on the other hand, is designed for those seeking a more streamlined, multi-channel solution. It offers all the advantages of the S2150 but expands the capability to serve multiple speakers in a home theater setup. It maintains the same high-quality Class D technology, providing 150 watts of power per channel across a wider range of configurations. The M2150 is ideal for audiophiles looking to build immersive audio environments, integrating seamlessly with modern home theater systems.

Both the S2150 and M2150 are equipped with advanced connectivity options, including digital inputs like USB, coaxial, and optical. This versatility ensures that they can be easily integrated into any audio setup, whether connecting to a computer for high-resolution music playback or linking to a digital audio source for simple streaming.

Another noteworthy characteristic of TacT Audio’s amplifiers is their robust build quality and sleek design. The combination of aesthetic appeal and durability ensures that both models not only perform exceptionally well but also enhance the visual aspect of any audio system.

In summary, the TacT Audio S2150 and M2150 amplifiers highlight the brand's dedication to high-fidelity audio through advanced technologies and user-friendly features. With their powerful output, DSP capabilities, and versatile connectivity options, these amplifiers represent a significant investment for anyone serious about achieving the highest quality sound in their home audio experience.
