AMPLIFIER SETTINGS
Stereo / Mono Input Configuration
The STEREO / MONO switch allows the Orion 2002 and 3002 amplifiers to use a single RCA
or high-level input to feed signal to both the right and left channels of the amplifier.
When the switch is to the right (MONO position), signal from the left input is routed to the
right channel. This is the preferred mode when bridging the amplifier into a single speak-
er. When the switch is to the left (STEREO position), right and left inputs are independent.
This allows a source unit with an internal balance to change the stereo imaging.
Internal Crossover Configuration
The Orion 2002 and 3002 amplifiers use a multi-position switch to determine the crossover
configuration. The multi-position switch is located on the adjustment side of the amplifier.
Listed below are the switch positions and their respective crossover configurations.
When the switch is to the left (FULL position), the crossover section of the amplifier is
bypassed. Amplifier output is full range. When the switch is in the center (HIGH position),
the crossover is configured for high-pass operation. The crossover is fixed at 100Hz at 12dB
per octave. When the switch is to the right (LOW position), the crossover is configured for
low-pass operation. The crossover is fixed at 100Hz at 12dB per octave.
Input Gain
The Orion 2002 and 3002 amplifiers have gain adjustments with an input sensitivity range
from 200mV up to 5V on the RCA inputs and 1V to 10 on the high-level inputs. This allows
easy integration from any source unit either with RCA outputs or speaker outputs. Refer to
the Testing the System and the Adjusting the Sound of the System sections for detailed
instructions on setting up the level controls.
INTELLi Bass Control
INTELLi Bass maximizes the performance of a subwoofer. INTELLi Bass allows for continuous
adjustment of low frequency boost. INTELLi Bass is a variable Q and variable frequency low
frequency boost. INTELLi Bass can be adjusted from 0dB of boost to 10dB of boost centered
at 45Hz. Initially the Q is very low. As INTELLi Bass is added, the Q becomes sharper. This
allows the Orion 2002 and 3002 to overcome acoustic deficiencies in your vehicle. The type
of enclosure used, the sub-woofer's excursion capability, personal preference, and attitude
determine acceptable boost levels.
WARNING! Exercise caution when setting INTELLi Bass. Maximum boost can potentially
cause woofer damage due to overexcursion.
