Introduction M/S-2150 X Introduction Congratulations on your purchase of your M/S 2150X. 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. Th

DRC M/S-2150 X Dynamic Room Correction M/S-2150 X is designed to support full range and subwoofer Dynamic Room Correction (DRC). All software necessary to perform this task is built into each M/S-2150 X. However M/S-2150 X does not have built in microphone preamp and it does require an external digital microphone preamp such as BOZ RCS-16M. With RCS-16M up to 16 channels of DRC can be performed. Each M/S-2150 X channel can be configured as main (full range) or subwoofer channel. After measuremen

DRC M/S-2150 X Equal loudness curves represent the SPL that different frequencies need to have in order to be perceived as two tones of equal loudness. For example, a 200 Hz tone at SPL of 50 dB will have the same perceived loudness as a 1000 Hz tone at SPL of 40 dB. In this case both 200 Hz and 1000 Hz tones have a loudness of 40 phons, and they both belong to the 40 phons equal loudness curve. CAUTION CAUTION Fletcher-Munson equal loudness curves As it can be seen from the graph, in comparison

Connections M/S-2150 X Digital output The M/S 2150 X 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. Digital Output RS-232 interface The M/S 2150 X has two RS232 interface ports: ports - INPUT - AUX Use the INPUT port for communication with your Tact master controller or Personal C

Connections M/S-2150 X Speaker output If you are using two or more M/S-2150 X amplifiers, and your speakers allow for multi- (Biamped operation) amping, you can configure the system to run in biamped, tri-amped or multi-amp mode. 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 frequency range). The following are two examples of making a biamped connection: Horiz
