,INE/UTPUT#ONFIGURATIONS
The line outputs on Orion amplifiers offer easy system expansion and
can be used to route signal from the RCA line outputs to the next
Orion amplifier’s RCA line inputs in the signal chain.
)NTERNAL#ROSSOVER#ONFIGURATIONS
The crossover section of the Orion HCCA10002 and HCCA10004 ampli-
fiers are continuously variable and extremely flexible. There are eight
different crossover configurations possible allowing high-pass, low-
pass, and band-pass operation. This circuit is designed to optimize the
performance of subwoofers in all types of enclosures.
When using Orion loudspeakers, minor deviations from the recom-
mended frequency ranges can provide superior results depending on
your speaker locations and your vehicle acoustics. Setting crossover
frequencies higher than recommended will not cause damage and
may provide superior sonic results depending on your system’s perfor-
mance goals. Refer to your loudspeaker owner’s manual for assistance
in choosing the proper crossover frequencies for your system.
WARNING! DO NOT set crossover frequencies lower than the speak-
ers recommended operating range. This can cause driver failure that
is not covered by the manufacturer’s warranty.
#ROSSOVER3WITCH
Controls the type of filter for the onboard active crossover. The
HCCA10004 has two switches, the upper switch is for channels 1/2, the
lower switch is for channels 3/4.
All position does not attenuate any frequencies and is for full
range speaker systems.
High attenuates low frequencies and is used for mid-range speak-
ers and tweeters.
Low attenuates high frequencies and is used for subwoofer
speakers.
,OW0ASS#ROSSOVER
When the switch is in the middle (ALL position), the low-pass crossover
is bypassed. When the switch is to the left (LOW position), the low-
pass crossover is active. The low-pass crossover is continuously variable
from 50Hz to 2kHz.
