To make sure that both amplifiers will process Left and Right channel check
Amp#1 and Amp#2 InOut menu options. They should be set as follows:
OUTPUT: L R
SOURCE: L R *
OUTPUT: L R

Amp#1 InOut menu
Also make sure that initially for both amplifiers DELAY and LEVEL menu options
are set to as follows:
LEFT RIGHT
0.00 0.00 msec
LEFT RIGHT
0.0 0.0 dB
The next step is crossover filter selection for both subwoofers and main channels.
The crossover filter selection consists of setting subwoofer low-pass filter cutoff
frequency and filter order (filter slope), and of setting main channel high-pass cutoff
frequency and filter order (filter slope). Your loudspeaker manufacturer usually
recommends these parameters. In this example we assume that crossover
frequency is 100 Hz and the filter order is something we want to experiment with.
Each M/S 2150 X amplifier supports up to 9 crossover presets. Here we program
preset 1 (CRO- 1) with 10-th order filter as shown bellow.
L: LO HO FL-Hz FH-Hz
HP -- 10 ----- 100
R: LO HO FL-Hz FH-Hz
HP -- 10 ----- 100
