Signal Input and Output Configurations
the input section of the amplifier consists of gain controls, high pass
and low pass crossovers controls, Bass Boost control and RCA inputs
and outputs . the input section makes it easy to adapt this amplifier to
most system configurations .
Input Gain
these orion amplifiers have level adjustments to allow for easy inte-
gration with any source unit . the input sensitivity can be adjusted
from 200mV to 8V . Refer to Testing the System and Adjusting the
Sound of the System sections of this guide for detailed instructions on
setting the gain .
Line Output Configurations
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 .
Internal Crossover Configurations, Flat (full range)
the crossover section of the orion XtR2504 and XtR5004 amplifiers
are continuously variable and extremely flexible .

recommended operating range . this can cause driver failure that is
not covered by the manufacturer's warranty .
Crossover Switch
Controls the type of filter for the onboard active crossover . the orion
XtR2504 and XtR5004 have a switch for the selectable crossover .
Full 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 .
Low-Pass Crossover
When the switch is to the center (FULL position), the low-pass cross-
over is bypassed . When the switch is to the left, the low-pass crossover
is active . the low-pass crossover is continuously variable from 50Hz to
2000Hz .
