Configuring the SLX-4
Input Selector Switches :
Any of the four output sections can be fed by either the front or the
rear input. If you are using a single input these switches should be set in the
same position (i.e. front). A variety of configurations are possible using
different combinations of these switch settings.
HP/BP Switch :
This switch disengages X3 from the HP/BP output. In the HP
position the output is high pass and in the BP position the output is band
pass.
LO/BP Switch :
This switch disengages X4 from the LO/BP output. In the LO
position the output is low pass and in the BP position the output is band
pass.
Stereo/Mono Switch :
Selects between normal stereo operation and summed mono for the
low pass output. In the stereo position, signal will be supplied by the input
designated by the input selector switch. In the summed mono mode, the
signal for the low pass is derived from both the front and rear outputs.
X1/X3 :
In the X1 mode, the high pass output has its normal frequency
range and is fed by the input that is designated by the X1 input selector
switch. In the X3 position, the high pass output ties off of the X3 crossover.
The X3 frequency control will adjust both the top end of the X1/X3 band
pass and the crossover point of the highpass output. The X1 frequency
control will become invalid in this mode. This option will most often be used
in four-way applications involving a band passed midrange and a tweeter
with a high frequency crossover point.
12/24dB/Octave Switch :
Selects between normal 12dB/octave slope or a steeper
24dB/octave slope for the low pass output only. When the 24dB/octave
mode in engaged, the low pass output is automatically mono.
The following pages contain some sample
configurations and their relative switch
positions.
