Three way Active/Two way Active Switch
Two way active: The “full range” LF input is applied to pins 1+ and 1- and the -6dB per octave shading
network is applied to one of the LF transducers using the Low Frequency Select switch (above).
Three way active: Shading network is NOT applied (shading must be provided by upstream signal pro-
cessing). Connect the full-range input signal to pins 1+ and 1-, connect the shaded (processed) signal to
pins 2+ and 2-. To flip shaded transducer location, use the Low Frequency Select switch or alter signal
processing. Default Low Frequency Select switch position for three way mode is position A; if put in
position B, connections (per Table 1) to LF transducers A and B are interchanged.
Low Frequency Select Switch
The WideLine is a three way design (shaded, non-shaded and high frequency) with shading provided by
a passive network in two way mode or upstream signal processing (DSP) in three way mode. This allows
switch position selection for use as either “house left” or “house right”, without the need to flip boxes.
Two way Mode: The shading switch allows either low frequency transducer to be selected as the
shaded unit (bass only) by inserting a -6dB per octave network. The switch handle points to the side of
the non-shaded (full range) low-frequency transducer.
Three way Mode: The internal -6dB per octave network in NOT applied to either LF transducer. Shad-
ing is accomplished with signal processing. The switch handle points to the side of the non-shaded (full
range) low-frequency transducer ONLY IF the full range signal is applied to pins 1+ and 1- and the
shaded signal to pins 2+ and 2-. Default position for three way mode is position A; if put in position B,
connections to LF transducers A and B are interchanged.
