TRI AMP/BI AMP Switch
TRI AMP: Shading network is NOT applied (shading must be provided by upstream signal processing). Connect the full- range input signal to pins 1+ and 1-, connect the shaded (pro- cessed) signal to pins 2+ and 2-. To flip shaded transducer location, use the MF (UNSHADED) SELECT switch or alter sig- nal processing. Default MF (UNSHADED) SELECT switch posi- tion for three way mode is position A; if put in position B, connections (per Table 1) to LF transducers A and B are inter- changed.
BI AMP: 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 MF (UNSHADED) SELECT switch.
MF (UNSHADED) SELECT Switch
The WideLine is a three way design (shaded, non-shaded and high frequency) with shading provided by a passive network in BI AMP mode or upstream signal processing (DSP) in TRI AMP mode. This allows switch position selection for use as either “house left” or “house right”, without the need to invert boxes.
MF (UNSHADED) SELECT Switch: BI AMP Mode
BI AMP: 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 unshaded (full range) low-frequency trans- ducer.

TRI AMP: The internal -6dB per octave network in NOT applied to either LF transducer. Shading 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 TRI AMP mode is position A; if put in position B, connections to LF transducers A and B are interchanged.
