Using Passive Speakers with Subwoofers in Bi-amplified Mode
TXD series two-way loudspeakers can also be operated in bi-amplified mode together with any of the available subwoofer
enclosures. An external 2-in, 4-out crossover such as the LMS-D24 is required with a crossover frequency of 125Hz,
24dB/octave slope, Linkwitz-Riley. To operate TXD systems in bi-amplified mode, it is necessary to by-pass the internal
passive crossover in the bass cabinet. To do this, undo the four screws holding the pole mount socket in place, and firmly
pull the pole mount out of the cabinet together with the passive crossover selection wiring. In the case of the TXD-215 and
the TXD-218, remove the lower side pole mount. To by-pass the internal passive crossover, remove the yellow link wire
from the red and connect it to the black as shown in the diagram, and replace the pole mount in the cabinet.
Bi-amplified Systems
TXD-252 and TXD-15M loudspeakers can be operated in bi-amp mode, using two separate amplifiers and an external
electronic crossover such as the LMS-D24.
