The other option "
2.1
" is suitable for a stereo subwoofer; in that case the subwoofer will be fed by the mono sum of the
left and right input channels, -6dB.
Generally in the latter configuration one will use a hi-pass filter
(either 12 or 24dB/octave)
on the left and right speakers, in
combination with a low-pass on the subwoofer, 12 or 24dB/octave, and invert the subwoofer polarity if appropriate.
Underneath is an example
(fig. 5)
to illustrate the EQ/crossover settings used for a 2.1 situation, with a crossover point set at
100Hz, 24dB/octave, normal subwoofer polarity.
• "Individual levels" sub-menu (fig. 6)
As can be seen this window allows individual level adjustment of each
channel within a system, whether it is 5.1 or 2.1.
Clicking "
Send
" is required after any change to the faders positions,
for them to become effective.
On the other hand, ticking/unticking the "
Mute
" and "
Solo
" boxes available
for each channels will have immediate effect.
The faders range is adjustable
(see "Preferences", "Levels" tab, "other levels")
.
• "Master level" sub-menu (fig. 7)
This window is for setting the system Master level.
The fader range can be adjusted
(see "Preference", "Levels" tab,
"Master level")
.
A general "
Mute
" is available.
The "
Mono
" function is reserved for a stereo or 2.1 system, and operates
only when using the digital inputs. The mono signal is obtained by
summation of both channels
(L+R – 6dB)
.
It is worth bearing in mind that in this window data changes are
immediately passed on to the speakers.
