HIGH-PASS CROSSOVER
When both push buttons are in the “out” position, the high-pass crossover is by-
passed.
MID AND TWEETERS
When both push buttons are in the “in” position, the high-pass crossover is active in
the “HIGH” frequency range. The high-pass crossover is continuously variable from
100 Hz to 10 kHz. This setting is used for crossing over midrange and tweeter speakers.
Set the INTELLi Q level to “0 dB.” NOTE: When the high-pass crossover is in the
“HIGH” frequency range, the frequency indicators represent 1/10 of the crossover fre-
quency. For example, 35Hz = 350Hz.
WARNING!!! When using the crossover in the “HIGH” range, it is not
recommended to use the INTELLi Q as it may potentially
damage your midrange or tweeter speakers.
HIGH-PASS WOOFERS
When only the push button to activate the high-pass crossover is in the “in” position,
the high-pass crossover is active in the “LOW” frequency range. The high-pass cross-
over is continuously variable from 10 Hz to 1 kHz. The high-pass crossover is now opti-
mized for use as a subsonic filter for subwoofers. Additionally, boost can be added at
the high-pass crossover frequency for improved bass output while still protecting the
woofer from excessive excursion. The INTELLi Q adjustment allows up to 10 dB of
boost at the crossover frequency. Care must be taken when setting the INTELLi Q at or
near the maximum boost.
