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.
Introduction Congratulations on your purchase of your M/S 2150. You 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, CAUTION with the narrowest pulse being a mere 10 nanoseconds wide. The clock frequency therefore is 98 MHz.
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 TosLink (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.
M/S 2150 Connections Digital output The 2150 amplifier has a digital pass through. The digital input signal is passed to the digital output without processing or volume control. The sampling rate is the native sampling frequency of the input. CAUTION NOTE: that this output is not active when analog input is selected.
M/S 2150 Connections Trigger outputs The M/S 2150 has a trigger “IN” and “OUT” to provide on and standby control from a trigger device and to pass the trigger signal to another device. Trigger Connectors AC mains input Connect the M/S 2150 to the AC mains wall socket. CAUTION: Use the supplied IEC mains cable, or a 3-prong grounded cable only. Digital Output Speaker output (normal operation) The 2150 amplifier has one pair of high quality WBT speaker terminals.
M/S 2150 Connections Speaker output (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).
M/S 2150 Connections Vertical Biamping LEFT SPEAKER RIGHT SPEAKER HIGH HIGH LOW LOW RIGHT SPEAKER LEFT SPEAKER HIGH + - HIGH + - LOW LOW + + - - Tact Audio 13
M/S 2150 Connections Biamping - continued When two or more 2150 amplifiers are configured in a bi-/tri-amped setup, both the signal and the RS232 TacT System Bus must be daisy chained between the amplifiers. The same signal flow is applicable for both horizontal and vertical bi-amping. From source CAUTION Digital signal (coax/SPDIF) From RCS2.0S, RCS2.
Front Panel Controls The front panel controls on the 2150 amplifier will allow you to control all of the amplifiers main features. All secondary options are controlled with menus using the remote control or the supplied software. The exclusive “TacT wheel” is the master volume control.
Remote Control The remote control is used to access the front panel display controls and menus.
Remote Control 1 - STANDBY The STANDBY button will turn the M/S 2150 “ON” or it will place it into “STANDBY” mode. When in standby mode, the unit is placed into a low power “idiling” state. The standby button is also used to save changes that were made in the menu editing parameters. By placing the unit into standby the current settings are saved. 2 - DIGITAL The DIGITAL button will scroll sequentially, allowing the selection of one of the 5 digital inputs.
Front Panel Display Main screen When the 2150 amplifier is turned ON and the system loading sequence has completed, the amplifier will display the normal operating main screen. Main Screen : 1 CAUTION INPUT: CD/Transport -17.9 dB Fs= 44.1 2 3 1 - Name for input selection 2 - Master level in dB 3 - Input sampling frequency indicator. MAIN menu The Main menu of the M/S 2150 has three pages of general menu selections.
Front Panel Display DELAY menu The Delay menu controls the system’s time alignment. The system’s time alignment can be adjusted by changing the delay time for the left and right outputs independently. . Delay Menu : LEFT RIGHT 0.00 0.00 msec 1 1 - Left and Right channel independent delay time settings. Use the “LEFT” and “RIGHT” navigational buttons to highlight an option and use the “UP” and “Down” buttons to change its value . LEVEL menu The Level menu controls channel balancing.
Front Panel Display ADC menu (ADC module optional) The M/S 2150 may be equipped with an optional state of the art Analog to Digital Converter. To further enhance the converter’s performance, the system offers two selectable gain values for the ADC input stage. These two values may be assigned to each input independently. ADC Menu : 3 2 CAUTION GAIN: LOW IN:2 LOW HIGH 1 1 - Assignable gain values. 2 - Input channel currently selected. 3 - Active gain setting for selected input channel. LOW = -6.
Front Panel Display TRIG menu The trigger menu is used to control the behavior of the 2150 amplifier when a trigger signal is detected. When the input trigger is set to “ON” and a trigger signal is detected the amplifier will turn ON. The amplifier will stay in or switch to “STANDBY” mode if there is no trigger signal detected.
Front Panel Display OPT menu (Options) The options menu is designed to control the systems maximum signal level “MAXLEV”, signal detection threshold “DTHR” and wheel speed “WH”. CAUTION NOTE: Wheel speed is only available on the M2150. Options Menu : MAXLEV DTHR +12.0 -6.0 dB 1 WH 5 2 3 1 - Maximum Level setting. 2 - Detection setting. 3 - Wheel speed setting. - Max Level controls the system’s maximum signal level. For example: if this option is set to -3.
Front Panel Display INOUT menu This InOut menu is used to set the channel output configuration for the M/S 2150. NOTE: For vertical Biamping, the source menu option should be set to “L”+”L” for the amplifier that drives the LEFT speaker, and “R”+”R” for the amplifier that drives the RIGHT speaker. 2 InOut Menu : OUTPUT: SOURCE: L L R R * 3 1 1 - Source selections for output. 2 - Fixed output speaker posts. 3 - Active source setting.
Front Panel Display REM menu (Remote) The remote menu allows for disabling or enabling the remote control. Once the remote control is disabled the unit can only be controlled from the front panel of the unit. An alternate way to enable or disable the remote control is to press the front panel “ANALOG” and “DIGITAL” button simultaneously - this can be used to change the remote control state without entering the REM menu. CAUTION Remote Menu : 2 REMOTE CONTROL: ON OFF ON 1 1 - Remote control settings.
Front Panel Display ADDR menu (Address) The address menu allows for the setting of the “address” for the unit. The default address setting is “001”. If multiple amplifiers are used together, different addresses will allow individual control of each amplifier. 2 Address Menu : CURRENT ADDRESS: 001 ADDRESS: 001 1 1 - Address settings. 2 - Active address setting. Use the “UP” and “DOWN” navigational buttons to select the desired system address and then press the “ENTER” button to select it.
GAIN menu The gain menu allows for an increase in the overall volume level of the amplifier. There are four gain settings that are available: 0dB, 6dB, 12dB, and 18dB. The amplifier will increase its overall gain by the amount set in the “Gain” setting. For example if “0dB” is selected the amplifier will output +0dB at maximum volume (99), if “18dB” is selected the amplifier will output +18dB at maximum volume (99). CAUTION Gain Menu : Gain 12 dB 1 1 - Active gain setting.
TacT 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.
