OPERATING MANUAL AND USER GUIDE
Tuning the Room:
• The controls on the crossover provide level adjustment to the frequency range you send
to the amplifier and ultimately the loudspeakers.
• To tune the system to the room, it takes some practice and patience. Remember to find
out the speaker manufacturer's recommended crossover frequencies for the various
elements in order to set the crossover accurately. Be careful when doing this by "ear".
What sounds right to you may be wrong for the components' long-term reliability. To be
safe, set the output level controls all at maximum so that they are at the same output
level (at lower settings, potentiometer tolerances could cause them to be different) then
counter-adjust (lower) the crossover's input level to avoid over-driving the power amps.
• When your ear gets calibrated, you can tune the system by ear.
• Use a reference-test CD or tone generator to play sine wave tones ranging from 50
to 16k Hz through the system and adjust the frequency response of the system so the
sound from the bass, mid and high frequency speakers is about the same level. Minor
adjustments by ear can be made later, but only minor adjustments.
• Leave the crossover alone until the next gig or the room changes significantly. However,
if it changes too much, it is too late to run the above procedure and you must “do it by
ear”.
A continuously variable frequency crossover is a very valuable tool for the traveling
musician. It allows you to get the best sound in a variety of venues. As we know, all rooms
are not created equal. They have their own personality. That is to say, your sound system
will not sound the same from room to room. Using equalisers and crossovers correctly will
help you maintain “your sound”.
