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 CAUTION with the narrowest pulse being a mere 10 nanoseconds wide. The clock frequency therefo

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. Digital Input Section Analog input The 2150 amplifier has 3 stereo analog inputs whith the optional ADC module in- (optional ADC module) stalled: - two analog stereo s

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. NOTE: that this output is not active when analog input is selected. CAUTION CAUTION Digital Output RS-232 interface The M/S 2150 has two RS232 interface ports: ports - INPUT - AUX Use the “INPUT” port for communication with your Tact master controller or Pe

M/S 2150 Connections Speaker output If you are using two or more 2150 amplifiers, and your speakers allow for multi- (Biamped operation) amping, 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 fre- quency 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 connec- tion: Horizontal Biamping LEFT RI

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 amplifi- ers. The same signal flow is applicable for both horizontal and vertical bi-amping.
