The next section holds the
Channel Selection
and
Crossover
.
You can select a channel to tune by clicking on the desired speaker in the car
diagram/Delay section or by clicking on its box in the DSP Channel column. You
can pick channels on at a time or you can pick them by pair. Double clicking the
dot between a pair of channels links that pair. Similarly, if one channel is already
chosen and active, then clicking on the dot will pair them.
This is important as you should always set crossovers by channel pair so the left
and right speakers will be the same. It is also easiest to do initial equalization by
channel pair.
Each channel has a High Pass (HP) and a Low Pass (LP) filter. You can control the
frequencies of the filters by highlighting the FREQ box and typing in a value or
by using the keyboard up/down arrows. You can choose the Shape of the
crossover from Butterworth, Linkwitz-Riley, or Bessel and the Slope using the
drop-down menus. The default crossovers are all 24dB/Octave Linkwitz-Riley.
The best source for information on the proper crossovers for your own speakers
is the speaker maker. He can tell you what crossover to use and also how much
power the speakers can handle at different slopes and frequencies.
