SETTING THE CROSSOVER POINT FOR THE REAR (MIDRANGE) OUTPUT
Usually the MID output is a BANDPASS design. It is achieved by setting the BANDPASS switch to
ON and using both BP HIGH PASS and BP LOW PASS dials. The BP LOW PASS dial will set the
lower frequency limit for the midrange speaker. The BP HIGH PASS will set the upper frequency
limit for the midrange (on the REAR output) AND the lower frequency limit for the tweeter (on
the FRONT output). Set the desired BP LOW PASS frequency to set the lower frequency limit for
the midrange between 30 Hz and 500 Hz, or, using the MULTIPLIER SWITCH, between 300 Hz
and 5 kHz. This will typically be set at the same frequency you set the SUBWOOFER LOW PASS
frequency.
SETTING THE CROSSOVER POINT FOR THE FRONT (HIGH) OUTPUT
•
Set the desired frequency cutoff using the HIGH PASS dial for your HIGH output, such as
tweeters. The FREQUENCY MULTIPLIER switch must be set to X10, as most tweeters cannot
safely operate at less than 3kHz. This will allow you to cross the output between 300 Hz
and 5 kHz.
•
You also have the option of running midbass or midrange level in the FRONT by using the
frequency range from 30 Hz to 500 Hz with the FREQUENCY MULTIPLIER switch set to X1.
FINE TUNING YOUR SYSTEM
One very important part of fine tuning your system is properly level matching the signal from the
source unit to the XEX-23 crossover and from the crossover to the amplifiers. Level matching
is the process of calibrating the audio signal from the Source unit all the way to the amplifiers
to eliminate unwanted noise and maximize the dynamic headroom. When the system is properly
adjusted you should achieve maximum output before distortion at about 80% volume on the
source unit.
