3. Introduction
Please read this entire manual before commencing your installation.
The USL XTM series crossover module has been designed for high performance, ease of use, and
years of trouble free service. No special tools are required. The components that make up the
XTM are of computer grade for reliability. All USL equipment has been “burned-in” at the factory for
an extended period in order to eliminate the possibility of premature failure. Unpack the unit care-
fully. If the container has been damaged, thoroughly inspect the equipment to make certain that
there is no hidden damage. File a claim immediately with the carrier if any damage is found. Also
advise your dealer or the factory.
The USL XTM-300 is a bi-amp crossover chassis for use with the XTA-680EA analog crossover
card or the XTD-680 digital crossover card, each of which provides three channels (left, center,
right) of bi-amp configuration.
The XTA card provides the low cost ability to set 11 distinct crossover frequencies and 4 low fre-
quency time delays for the left, center and right channels.
The optional XTD-680 digital crossover card provides increased flexibility for setting the left, center,
right and LFE channels including parametric, screen and horn EQs, gains and delays . The card is
configured with an easy to use graphical user interface that runs on a laptop computer communi-
cating via a USB cable. A library of existing speaker types is provided, or each of the features may
be configured manually.
NOTE: Although the XTD card is capable of supporting tri-amp configurations, the XTM-300 does
not support tri-amp use. Should you need tri-amp support, please contact USL.
You will need to supply the following materials and tools:
