O
PERATION
With LFE Connection
If you are using the LFE input, the subwoofer's CROSSOVER
control is NOT active, because this function is controlled by your
surround processor.
When using the LFE input, set the subwoofer's VOLUME control to
"Max" and calibrate the subwoofer level along with the other
speakers according to the set-up instructions in the owner's
manual for your surround receiver/amplifier.
Other Connections
If you are using any other connection method, start with the
subwoofer VOLUME control in the "9 o'clock" position and the
CROSSOVER in the 12 o'clock position.
To fine-tune the subwoofer's volume and crossover frequency
settings, listen to familiar material with powerful bass at a typical
listening level.
Bass response should not overpower the room, but instead
contribute to a harmonious blend across the entire musical range.
Many users have a tendency to set the subwoofer volume and
crossover too high, believing that a subwoofer is there to produce
lots of boom and shake the room to make its presence felt.
This is not entirely true.A subwoofer is there to enhance bass,
extending the response of the entire system so that bass can be
felt as well as heard.
However, overall balance must be maintained; otherwise, the
music will not sound natural.
An experienced listener will set the volume and crossover of the
subwoofer so that its impact on bass response is always there, but
is never obtrusive.
Phase Control
The proper adjustment of the subwoofer's rear panel phase switch
for your system depends on several variables such as room size,
subwoofer placement and listener position.
Listen to a familiar selection with powerful bass at a typical
listening level, while occasionally changing the position of the
phase switch.
The position which provides maximum bass output at your
listening position is the correct position.
Auto-On Signal Sensing
The Oreus Subwoofer incorporates automatic signal-sensing
circuitry which turns the subwoofer on instantly when an audio
signal is present. When a signal has not been detected for
approximately 1.5 minutes, the subwoofer automatically goes into
standby mode.
