A properly setup Home Theater Surround Sound System
will have all Loudspeaker levels adjusted to the same vol-
ume level in the Listening/Viewing Area. The MX136 in-
cludes a built-in test signal generator and its output is
switched into each Loudspeaker, either automatically or
manually. The correct volume level for each Loudspeaker
can be determined in the Listening/Viewing area, either with
a sound pressure meter or by listening. Level adjustments
are made in 1dB steps, over a plus or minus 12dB range, by
using the Remote Control Left and Right directional
push-buttons.
Notes: Before adjusting the SPEAKER LEVELs, perform the
SPEAKER SIZE and SPEAKER TIME DELAY
adjustments first. The SPEAKER LEVEL On-Screen
Display will only indicate channels that have been
switched On in the SPEAKER SIZE Menu. A sound
level pressure meter will greatly aid in adjusting the
Loudspeaker levels and the Left Front Loudspeaker
Volume level can serve as a reference.

2. Using the Up
or Down
directional push-buttons,

quires less push-button presses) or Manual (quicker
