CREATING A PROGRAM
9.4 OUT 1, OUT 2, etc.
Each tab selects an output channel. Use this
screen to program crossover frequencies, filter
type, and up to five parametric EQ’s. In addition,
the same programming choices as on the GAIN
screen are duplicated here, but just for the
selected output channel.
9.5 Crossover Filters:
The Low and High frequencies set the frequen-
cy bandwidth for the selected channel of the
crossover. For example, in a three-way
crossover, the Low Band might be 60 Hz to
200Hz; the Mids 200Hz to 1800Hz and the
Highs 1800Hz to 15 kHz.
The different filter types and slopes, including
Bessel, Butterworth, Linkwitz-Reilly and shelv-
ing filters with different Q values each offer par-
ticular advantages and disadvantages depend-
ing on the application and conditions.
