SETUP
This menu option is used to select the playback mode.
In stereo mode, each of the two channels of the AS-250 receives the
corresponding left or right signal of the playback-source.
If the mono mode is selected, the DSP generates a mono sum signal
and outputs this to both channels equally. The total level is cor-
rected in such a way that no volume change occurs. This mode is
recommended in combination with further nuPros. See page 9 in the
section „Further configurations“.
n
SUBOUT
The subwoofer output outputs a low-passed mono sum signal. In
this menu you can set the desired crossover frequency for the sub-
woofer. Use the
and
keys to change the crossover frequency.
n
SYS HP
(High-pass and crossover frequency)
In this menu, you can set the high-pass (lo-cut) filter frequency.
This is particularly useful if you connect a subwoofer to your nuPro
speaker.
Use the

keys to activate (ON) or deactivate (OFF) the
filter. If the Filter is set to ON, press
or the MENU key to get to
the next menu where you can set the proper frequency, using the
and
keys
Note:
Setting the high-pass filter to a higher frequency increases
the maximum possible sound pressure level from your nuPro loud-
speaker.

LIM DS

sage displayed (ON) or not (OFF).
