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 33 on page 41.
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,
LS, LFE, RS and S will
illuminate.
Refer to figure 34.
B. If a Digital Input Signal
Source is 2 Channel Sur-
round Encoded, the front
panel INPUT FORMAT
LEDs L, R and S will il-
luminate.
Note: This will only occur when the SURROUND
MODE is in CINEMA1 or CINEMA2.
C. If the Analog Input Signal Source is Stereo, the IN-
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 DOLBY DIGITAL Display will illuminate when
the input contains Dolby Digital Encoded Signals.
Refer to figure 35.
F. The EX (Dolby
Digital) Display
will illuminate
when the input
contains Dolby
Digital EX En-
coded Signals.
G. The PRO
LOGIC IIx Dis-
play will illumi-
nate when the
Surround Mode Selector is turned to CINEMA1 or
MUSIC 1 positions.
H. The DIGITAL SIGNAL Display will illuminate
when the MX135 is processing a Digital Encoded
Signal.
Figure 34
I. The DTS Display will illuminate when the input con-
tains DTS Encoded Signals.
J. The DTS ES Display will illuminate when the input
contains DTS ES Encoded Signals.
K. The NEO:6 Display will illuminate when the Sur-
round Mode Selector is turned to CINEMA2 or MU-
SIC 2 positions.
L. The 2 CHANNEL Display will illuminate when the
Surround Mode Selector is turned to STEREO (2
CHANNEL) positions.
Output Format:
M. The OUTPUT FORMAT LEDs indicate the SUR-
ROUND MODE selected and the active audio chan-
nels. Refer to figure 36.
Note: The following example of the illuminated LED is
based upon a 7.1
channel system. If
your system is
configured as
something other than
7.1 (e.g. no Center
Loudspeaker or a
single BackSurround
Loudspeaker) then the
number of LEDs
illuminated will be
different.
N. STEREO mode will cause the L, R and SUB LEDs
to illuminate.
O. MUSIC 1, 2, 3, and 4 modes will cause the L, C, R,
LS, SUB, RS, LBS and RBS to illuminate.
P. CINEMA1 mode will cause the L, C, R, LS, SUB,
RS, LBS and RBS to illuminate.
Q. CINEMA2 mode will cause the L, C, R, LS, SUB,
RS, LBS and RBS to illuminate.
R. EXTERNAL mode will cause the L, C, R, LS, SUB,
RS, LBS and RBS to illuminate.
