11.1 Selecting
modes
The appropriate mode should be selected with the rear panel switch, and this
will be confirmed by the LED indicators on the front panel. The table in
figure
11.1 indicates the functions applicable to each front panel control.
4-way:
Use this mode for a conventional stereo four way speaker system, where each
of the four bands operate over different, non overlapping frequency ranges.
4-way HP:
Here the HI PASS front panel LED illuminates to indicate the mode. Use this
mode when two high outputs are required, such as when an additional long
throw driver is needed to augment an existing 3-way system. The crossover
frequency of the extra output is independent, and fully adjustable from the
standard high output crossover point.
4-way LP:
Here the LO PASS front panel LED illuminates to indicate the mode. Use this
mode when two low outputs are required, such as when temporary adding
sub-woofer loudspeakers to an existing 3-way system, or when it is required or
the sub-woofers to be run in a parallel overlap mode with the normal low
loudspeakers. The crossover frequency for the extra output is independent, and
fully adjustable from the standard low output crossover point.
