FILTER SETTINGS

The H8 DSP has five crossover filters, one for each output channel. Each filter allows the
setting of a single output channel parameters
1. Xover L/R Link: modifications applied to one of the channels (right or left) will also
automatically be applied to the other one. To do so, click on the blue led which will light up.
Xover L/R Link manages all Filter Settings adjustments except Set Distance (Delay).
2. Invert Phase: it inverts the phase of the channel under examination by 180°.
This can be done by selecting the green light which will light up.
This can be useful to solve phase alignment problems among the different filtered
channels.
3. Filter Type: it enables the selection of the different types of filters that can be assigned
to channels:
- Full Range
- Low Pass
- High Pass
- Band Pass
In STANDARD mode:
According to the speaker or speaker system selected during setup,
suitable filter types will be available.
E.g.: for the Front Woofer only Low Pass or Band Pass will be
available. For the Front Mid-Hi only High Pass and Band Pass
will be available, etc
In EXPERT mode:
Every speaker system selected has every filter type available.
WARNING:
In EXPERT mode, pay utmost attention to the filter
selection. Speakers have mechanical limits that must
not be exceeded, otherwise they could cause permanent
damage. When you select a filter, some optimized cut-off
frequencies are set by default to avoid breaking
the speakers.
E.g. if you select Low Pass for a tweeter, the default
frequency is instead suitable for a woofer and not for
the tweeter, which may be damaged.
4. Filter Model: it enables the selection of the type of filter to be applied.
- Linkwitz (default)
- Butterworth
When launching the H8 DSP software, it suggests Linkwitz as the standard filter model
for the speaker or speaker group connected to the corresponding channel. To apply the
opposite solution (Left / Right), turn the Xover L/R Link on.
If you modify the model to Butterworth, the change will be applied to both.
