Step 5
Connect power cords to the MPA 181T and other audio equipment .
Step 6
Adjust the MPA 181T input level, bass and
treble.
a. If connecting to a projector,
ensure that the volume on the
projector is at its lowest point,
then adjust the level of the
MPA 181T fully counterclockwise.
b. Set the projector volume to its maximum volume level
(no sound should come out).
c. Return to the MPA 181T and raise the level until sound
distortion occurs, then lower slightly until distortion
disappears. This setting ensures that, whatever the
projector volume setting may be, no clipping occurs.
d. Adjust bass and treble to preference.
