Low Pass Crossover
The low-pass crossover on the front channels and the rear crossover is continuously adjustable
from 45Hz tro 5kHz. There are three markings surrounding the crossover pot that designate
85Hz 2,500Hz and 3,500Hz respectively.
High Pass Crossover

120Hz 1kHz
350 Hz 100 Hz
When the high-pass crossover push button switch is in the "on" position and the "xIO" button
is on the on position, the high-pass crossover is activated in the "high" range. The crossover
frequency range is from 100Hz tolOkHz. There are four corner frequencies at 100Hz, 350Hz,
1,200Hz and 10kHz. This range is usefull when used with smaller diameter midrange and
tweeter speakers.
When the high-pass crossover push button switch is in the "on" position and the "xIO" button
is on the off position, the high-pass crossover is activated. The crossover frequency range is
from 10Hz tolkHz. There are four corner frequencies at 10Hz, 35Hz, 120Hz and 1kHz. This
range is usefull when used with larger diameter midrange and midbass speakers. Additionally,
this can also be used as a "subsonic filter" to prevent potentially damaging low-frequency
from getting to your subwoofer.

INTELLI Q
FRONT CHANNEL ADJUSTMENTS
In the world of "me too features," Orion has developed the
INTELLi Q
circuit that makes a real differ¬
ence in your automotive listening experience.
INTELLi Q (INTELL\gent\y
integrated Q adjustment) is actually an infinitely variable "Q" adjustment
found on the high-pass crossover of new XTREME and HCCA "Type R" power amplifiers. By changing the
"Q" of the high-pass from the industry standard 0.707 to any "Q" value between 0.707 and 3.5
(Figure
1
),
the high-pass filters essentially becomes two filters: a single band parametric equalizer and a subsonic
filter.
6c/B lOdB
By increasing the "Q" value from 0.707 to 3.5, the output is boosted up to lOdB at the high-pass
crossover frequency. The end-panel display is clearly marked in 3dB boost steps. Unlike other manufac¬
turers "subsonic filters," adjusting the
INTELLi
Q's high-pass crossover frequency easily performed
turning the crossover pot located directly to the right of the "Q" adjustment
(Figure 2).
The high-pass
crossover is continuously variable from 10Hz to 1kHz or 100Hz to 10kHz via a xIO frequency selector. By
correctly using the
INTELLi Q,
you can increase low frequency output by as much as lOdB!
Boosting the lower bass frequency does not come without trade-offs. As anyone knows, one of the
greatest potentials for woofer damage is caused by over excursion. Excursion is the forward and
backward movement of a woofer. When the signal to the woofer is incorrectly boosted, the woofer is
required to move more than is capable. For reference, a 6dB of boost requires a woofer to quadruple its
excursion to match the input signal. Ordinary bass boost equalizers boost without protection. Without
any protection, potential for damage is high.
The difference of
INTELLi Q
What makes the
INTELLi Q
different from all other equalizers or sub-sonic filters is that it can boost
lower frequencies the woofer can produce by lOdB while preventing over excursion that can damage the
woofer. The result is your woofer with the loudest low bass it can produce reliably. Here's how to use
it.
