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 (processed) signal to pins 2+ and
2-. To flip shaded transducer location, use the MF (UNSHADED) SELECT
switch or alter signal processing. Default MF (UNSHADED) SELECT
switch position for three way mode is position A; if put in position B,
connections (Table 1) to LF transducers A and B are interchanged.
BI AMP: The “full-range” LF input is applied to pins 1+ and 1- and the
-6 dB per octave shading network is applied to one of the LF transducers
using the MF (UNSHADED) SELECT switch.
MF (UNSHADED) SELECT Switch
The WideLine-10 is a 3-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.
BI AMP: The shading switch allows either low-frequency transducer
to be selected as the shaded unit (bass only) by inserting a -6 dB per
octave network. The switch handle points to the side of the unshaded
(full-range) low-frequency transducer.
TRI AMP: The internal -6 dB per octave network is 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.
