Follow DIAGRAM B for high and low frequency connections and check to see
that the mono-stereo switch inside the
XO-1©
is in the "mono" position.
CAUTION: WHEN BRIDGING AN AMPLIFIER, THE SPEAKER IMPEDANCE
MUST NOT BE LESS THAN 8 OHMS, AND MUST NOT BE GROUNDED AT
ANY POINT.

OUTPUTS
(Tri-amp System)
In a tramp system, individual amplifiers are used for bass, midrange, and treble
frequencies. In this configuration, two
XO-1's©
are "cascaded" in order to obtain
the third frequency range. (See DIAGRAM C for interconnections.)
All crossovers that are
not
PHASE COHERENT will cause some phase shift at
the crossover point. In a three way system with two crossovers, there will be
phase shift at both crossover points. By reversing the electrical phase of the mid
range driver, relative to the woofer and tweeter phase, this phase shift will be
compensated so that the system will be acoustically in phase, though electrically
out of phase. In most cases the system will sound better with the phase of the
mid range drivers reversed. Although this sound complicated, it is really quite
simple to do. After your system is installed and operating, reverse the leads to
your mid range drivers, so that the positive (+) lead from the amp is connected to
the negative (-) terminal on you speaker, and the negative (-) terminal to the
positive (+) lead on the amp. Listen to the system, then return the leads to their
original positions and listen again. Connect the leads in whatever position
achieved the best sound.
OPERATION/ADJUSTMENT/USE
1.
CROSSOVER FREQUENCY SELECTION
A. Remove the access plate on the
XO-1©.
IMPORTANT: IT IS NECESSARY
THAT ALL POWER TO THE SYSTEM BE TURNED OFF PRIOR TO NETWORK
REMOVAL/INSERTION.
WE REPEAT THE WARNING: DAMAGE TO YOUR SPEAKERS CAN BE
CAUSED BY REMOVING THE RESISTOR NETWORK WHEN THE SYSTEM IS
TURNED ON!
