FINE TUNING THE LOW-PASS CROSSOVER
600HZ
\
The crossover section is marked at four frequency points for
ease of system adjustment. These points are 45 Hz, 175 Hz,
600 Hz and 5,000 Hz. Specific crossover points can be chosen
based on the recommended operational bandwidth of your
speakers.
There are three small dots on the frequency range dial.
These dots represent commonly used ORION crossover fre¬
quencies. These crossover frequencies are 85 Hz, 2,500 Hz
and 3,500 Hz respectively.

HIGH-PASS CROSSOVER
MID AND TWEETERS
EBBllllul
When both push buttons are in the "out" position, the high-pass crossover is
bypassed.
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 frequency.
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.
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
crossover is continuously variable from 10 Hz to 1 kHz. The high-pass crossover is now
optimized 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 selected crossover frequency. Care must be taken when setting the
INTELLi Q at or near the maximum boost.
