Input Gain - Orion 250R & 275R Owner's Manual

Setting 4 inverts the output of both the left and right channels. Both left and right
gain controls are active. This configuration is useful for inverting one set of speakers
like rear speakers in front/rear system to improve staging in a vehicle.
Setting 5 inverts the output of the left channel. The left channel is 180° out of phase
from the right channel. Only the right gain control is active. This is the "MONO
BRIDGED" output configuration. Right Phase control determines the phase of the
output. When the Right Phase control is in the 0° position, the bridged output is in
phase with the rest of the system.
Setting 6 inverts the output of the bridged output . The mono bridged input is 180°
out of phase from the rest of the system. Only the right gain control is active. This is
the "MONO BRIDGED" output configuration. Right Phase control determines the
phase of the output. When the Right Phase control is in the 180° position, the
bridged output is out of phase with the rest of the system.
