Since M/S-2150 X is a two-channel power amplifier a crossover filter can be as-
signed to each output channel. Both Left and Right channels support LP, HP and
BP filters with a cutoff frequency set to any value between 10 and 24000 Hz with 1
Hz resolution. Filter order, which determines the filter slope, can be set to any
value from 1 to 12 with increments of 1 for each channel independently. The filter
slope is calculated as
Filter Slope = Filter Order * 6 (dB/Octave)
The CRO package is designed for applications such as:
• Subwoofer CRO design
• Multi way loudspeaker design
To access the CRO option enter the main menu screen and scroll to the right to
place the cursor on CRO and then press enter. This action will display the CRO
menu.
This screen shows that there is no crossover filter selected therefore both Left and
Right channel will output full range signal. Place the cursor next to field 2 and use
UP and DOWN buttons to scroll through all possible CRO presets. Note that when
this field displays Bypass edit control (field 3) is not visible. To select/engage
displayed preset press ENTER button. Selected CRO preset will be displayed in
