A

Bitstream Indicators:

When the input is a digital

source, one of these indicators will light to display the spe-
cific type of data signal in use.

B

DTS Mode Indicator:

This indicator lights when a

DTS-encoded source is playing and DTS Surround
decoding is in use.

C

Dolby Digital Indicator:

This indicator lights

when a Dolby Digital source is being played and Dolby
Digital surround decoding is in use.

D

Dolby Pro Logic II Indicator:

This indicator lights

when the Dolby Pro Logic II mode has been selected.

• 

It is possible to see the Dolby Pro Logic II indicator

lit simultaneously with the Dolby Digital indicator, even
though the Dolby Digital surround mode has been
selected. This is due to the specifications for Dolby
Digital processing, which require that the Dolby 
Pro Logic II mode be used any time a 2-channel
Dolby signal is detected.

• If you desire 5.1-channel audio, check the audio
settings in the menus for both your DVD player and
your DVD disc to make sure that a 5.1-channel Dolby
Digital sound track is available and has been selected.

E

Dolby 3 Stereo Indicator/Stereo Indicator:

The

entire indicator lights when the Dolby 3 Stereo mode
has been selected. When the surround modes are
turned off so that two-channel stereo playback is in
use, only the “ST” indicator will light.

F

Main Information Display:

This display shows

messages relating to the status, input source, surround
mode, tuner, volume level or other aspects of the
AVR 125’s operation.

G

DSP Mode Indicator:

This indicator lights when

any of the surround modes created by Digital Signal
Processing, or DSP are in use. These modes include
Hall 1, Hall 2, Theater and 5-Channel Stereo.

H

VMAx Mode Indicators:

This indicator lights when

the VMAx mode is in use.

VMAx F

appears when

the Far Field VMAx mode is selected;

VMAx N

appears when the Near Field VMAx mode is selected.
(See page 22 for a description of the VMAx modes.)

I

Logic 7 Mode Indicators:

These indicators light

when the Logic 7 mode is in use.

LOGIC 7C

ap-

pears for the Cinema version of Logic 7;

LOGIC 7M

appears for the Music version of Logic 7. (See page
22 for a description of the Logic 7 modes.)

J

Preset Number/Sleep Timer:

When the tuner is

in use, these numbers indicate the specific preset
memory location in use. (See page 25 for more infor-
mation on preset stations.) When the Sleep function is
in use, these numbers show how many minutes
remain before the unit goes into the Standby mode.
(See page 21 for information on the Sleep Function.)

K

Night Mode Indicator:

This indicator lights when

the AVR 125 is in the Night mode, which preserves
the dynamic range of digital program material at low

volume levels. This mode is only available with specially
encoded Dolby Digital sources. (See page 24 for a
description of the Night Mode.)

L

Speaker/Channel Input Indicators:

These indica-

tors are multipurpose, indicating either the speaker type
selected for each channel or the incoming data-signal
configuration. The left, center, right, right surround and
left surround speaker indicators are composed of three
boxes, while the subwoofer is a single box. The center
box lights when a “small” speaker is selected, and the
two outer boxes light when “large” speakers are select-
ed. When none of the boxes are lit for the center, sur-
round or subwoofer channels, no speaker has been
assigned to one of those positions. (See page 17 for
more information on configuring speakers.) The letters
inside each of the center boxes display active input
channels. For standard analog inputs, only the L and R
will light, indicating a stereo input. When a digital source
is playing, the indicators will light to display the channels
being received at the digital input. When the letters
flash, the digital input has been interrupted. (See pages
18–19 for more information on the Channel Indicators.)

M

Preset Indicator:

This indicator lights when the

tuner is in use to show that the 

Preset Number/

Sleep Timer

J

is showing the station’s preset

memory number. (See page 25 for more information
on tuner presets.)

N

Sleep Indicator:

This indicator lights when the

Sleep function is in use. The numbers in the Preset
Number/Sleep Timer Indicators will show the minutes
