Late Night
The LATE NIGHT Push-button turns a volume compres-
sion circuit On and Off. This feature suppresses loud
sounds or music that might disturb neighbors or others not
in the immediate area of the Home Theater. Soft levels are
also raised slightly so they are still listenable at reduced
overall volume levels. This works only on a Dolby Digital
Sound Track with encoded data that supports the compres-
sion function. Refer to figure 36.
Reset of Microprocessors
In the event that the controls of the MX134 stop function-
ing, there is a user reset function built in. Press the
POWER Switch to OFF and wait for two minutes. Then
Press the POWER Switch to ON. This will reset the
MX134 microprocessors. Refer to figure 36.
Note: The above condition is usually caused by either
interruptions in AC power and/or major changes in
voltage.
Front Panel Status
The three sets of front panel LEDs indicate the status of
Input Format, Operating/Decoding Modes and the Output
Format. Refer to figure 36.
Note: If a Digital Input is selected and the Digital Source
Component is not producing an output signal, none of
the Front Panel Status LEDs will illuminate.
Input Format
A. If the input signal source is Eight Channel Discrete,
the front panel INPUT FORMAT LEDs L, C, R,
LFE, LS, S and RS will illu-
minate. Refer to figure 40.
B. If a Digital Input Signal
Source is 2 Channel Surround
Encoded, the front panel IN-
PUT FORMAT LEDs L, R
and S will illuminate.

PUT FORMAT LEDs L and R will illuminate.
D. If an Analog Input Signal Source is Mono, both
channels will be receiving the mono signal and the
INPUT FORMAT LEDs L and R will illuminate.
Operating Mode Displays
E. The DTS Display will illuminate when the input con-
tains DTS Encoded Signals. Refer to figure 41.

THX default volume level is 65%, but it will change
if levels are adjusted up or down in the SPEAKER

Note: The THX Volume Sound Level will be loud with
most Home Theater Systems.

ROUND MODE selected and the active audio chan-
nels. Refer to figure 42.

EMA, THX CINEMA
