Unpacking the M/S 2150

Carefully remove the M/S2150 and accessory kit from the carton and check for shipping damage. Contact both the shipper and TacT Audio immediately if the unit shows any sign of damage from rough handling. All TacT Audio equipment is carefully inspected before leaving our factory .

KEEP SHIPPING CARTON AND PACKING MATERIALS for future use or in the unlikely event that the unit needs servicing. If this unit is shipped without the original packing, damage could occur and void the warranty .

Accessories

Operating voltage

Y ou should find the following items in the accessory kit:

- one AC mains cord

- RJ1 1 data cable

- RJ11-to-RS232 adapter

- 15’ RS232 cable

- CD-rom with software

- remote control

- 2 AAA batteries

- one manual

The 2150 amplifier is configured for either 110 or 220/240 volt operation. The operating voltage is clearly marked on the outside of the box and also on the rear panel beneath the AC mains connector .

BEFORE CONNECTING THE POWER, MAKE SURE THA T THE LABEL INDICA TING THE VOL T AGE MA TCHES THE VOL TAGE FOR YOUR COUNTR Y

The 2150 has three operating modes:

- OFF AC mains power is cut off, either via the front panel mains switch, or by unplugging the amplifier from the wall outlet.

- ST ANDBY The unit is powered but all outputs are muted and the display is off. The amplifier uses very little current and is “idling” or “sleeping”. Use the remote “ST ANDBY” button to toggle between ON and ST ANDBY.

- ON Everything is powered and ready to use.

Introduction

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

How does it work?

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 amplifiers. 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 controls 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 (volt age) the TacT M/S2150 delivers 58 volts, equivalent to 150 Watt s into 8 ohms. To reduce the volume the volt age of the power supply is reduced. This means that the volume control is no longer part of an active circuit.

CAUTIONCAUTION

Why hasn’t anybody

thought of it before?

8 T act Audio

Features:

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

M/S 2150 Connections

Digital input

The 2150 amplifier has 5 digital inputs:

- three RCA (S/PDIF) ( D1, D2, D3)

- one AES/EBU (XLR) (D4)

- one T osLink (S/PDIF) (D5)

All of the digital inputs support PCM audio data with sampling rates from 32kHz to 96kHz /16-24 bits, however , the AES/EBU and RCA/coaxial inputs support up to

192kHz.

Digital Input Section

Analog input

(optional ADC module)

The 2150 amplifier has 3 stereo analog inputs whith the optional ADC module installed:

- two analog stereo single ended (RCA) (A1, A2)

(Biamped operation)

Horizontal Biamping

If you are using two or more 2150 amplifiers, and your speakers allow for multiamping, you can configure the system to run in biamped or even tri-amped mode etc. This type of setup allows for one amplifier channel to drive a specific driver or frequency region. The most commonly used setup is biamped (two channels to each speaker: high and low). The following are two examples of making a biamped connection:

M2150 & S2150 Configurations

14 T act Audio

With its advanced DSP control, the M/S 2150 can enable digital crossovers (high-and low-pass) making it is possible to configure the 2150 amplifiers to virtually any system.

Examples of how a T acT active system can be configured:

1) Active two-way. The M2150 operates as master amp (control unit) and the

S2150 operates as slave amp. M2150 has a DSP-based high-pass filter and drives the high-section of the 2-way loudspeaker. S2150 has a low-p ass filter and drives the bass-section.

2) Active three-way. The Tact RCS operates as master pre-amp and the three S2150 operates as slave amps. The top S2150 has a DSP-controlled high-pass filter and drives the tweeter section. The middle S2150 has a High- and low-pass filter and drives the midrange section. The bottom S2150 has a low-pass filter and drives the bass section.

T acT M/S2150 Software

The M/S2150 is more than just an amplifier. With powerful features such as level balancing, time alignment, and assignable electronic crossovers, you can customize and build the amplifier system that you need, whether your system is biamped, triamped or more. Each of Tact’s amplifiers employ an RS232 in and out connection for control from a Tact master controller. Complete instructions for using the 2150 software can be found in the online help available in the software.
