20 SYSTEM CONFIGURATION
System Configuration
When you want to use the Night mode feature,
we recommend that you select the MID setting as
a starting point and change to the MAX setting
later, if desired.
Note that the Night mode may be adjusted direct-
ly any time that Dolby Digital surround mode is
selected by pressing the Night button
B
. When
the button is pressed, the words
D-RANGE
followed by the current setting (MID, MAX,
OFF) will appear in the lower third of the video
screen and in the Main In formation Display

within five
seconds to select the desired setting, then press
OK
F
to confirm the setting.
On the
DTS menu, the selection choices made
with the
‹

Buttons
Ea
on the remote
are determined by the type of DTS program
material in use.
When the 5.1 configuration is in use the AVR will
automatically select the 5.1 version of DTS
processing when a DTS data stream is received.
When a DTS 96/24 signal is detected, the
AVR 155 defaults to the DTS surround mode, but
reproduces the higher-resolution materials that
are present due to the higher sampling rate
automatically. See page 30 and 31 for a complete
explanation of the DTS modes.
On the
LOGIC 7
menu, the selection choices
made with the

Buttons
Ea
on the
remote enable Harman Kardon’s exclusive Logic 7
processing to create fully enveloping, multi -
channel surround from either two-channel Stereo
or Matrix-encoded programming such as VHS
cassettes, laserdiscs or television broadcasts
produced with Dolby surround.
You may select the Logic 7/5.1 Music, Cinema or
Enhanced modes. They work best with two-chan-
nel music, surround-encoded programs or
standard two-channel programming of any type,
respectively. Note that the Logic 7 modes are not
available when either Dolby Digital or DTS Digital
soundtracks are in use.
On the
DSP (SURR) menu, the selection
choices made with the

on
the remote select one of the DSP surround modes
that are designed for use with two-channel stereo
programs to create a variety of sound field
presentations. The choices available are Hall 1,
Hall 2, Theater. The Hall and Theater modes are
designed for multichannel installations. See pages
30-31 for a complete explanation of the DSP
surround modes. Note that the Hall and Theater
modes are not available when a Dolby Digital or
DTS soundtrack is played.
On the
STEREO menu, the selection choices
made with the

Buttons
Ea
on the
remote may either turn the surround processing
off for a traditional two-channel stereo presen -
tation, or select
5 CH Stereo. The latter
modes feed the stereophonic input signal to both
front speakers, to the rear speakers and to both
surround back speakers (if in use), while the
monophonic signal parts are spread over all
speakers, also the Center. See page 30-31 for a
complete explanation of the 5 CH Stereo modes.
After the selections are made in the Dolby, DTS,
Logic 7, DSP (Surround) or Stereo menus, press

Configuring the Surround Off
(Stereo) Modes
For superior reproduction of two-channel program
materials, the AVR offers two Stereo modes: an
analog Stereo-Direct mode that bypasses the
digital signal processing circuitry for a completely
analog signal path that preserves the purity of the
original signal, and a digital mode that is capable
of providing bass management for optimal
distribution of the low frequencies between
smaller speakers and a subwoofer.
Stereo-Direct (Bypass) Mode
When the analog Stereo-Direct mode is selected
by pressing the Stereo Mode Selector
S
until SURROUND OFF appears in the Main
Information Display
Ò
the AVR will pass the
analog source material directly through to the
front left and right speakers, bypassing the digital
processing circuitry.
In this mode, the front left and right speakers will
automatically be configured as
LARGE; it is not
possible to configure these speakers as
SMALL.
When the AVR is in the Stereo Bypass mode you
may still configure the subwoofer output so that
it is either turned off, with a full-range signal
going to the front left/right speakers, or you may
configure it so that the subwoofer feed is
activated.
The factory default setting is to have the
subwoofer turned off for this mode, but you may
change that setting by following these steps:
1. Press the Speaker Button
6

.
2. Press the OK Button
F
@
to activate the
configuration menu.
3. Press the
⁄

Buttons
D
on the remote or
the
‹

Buttons

on the front panel to
select the desired option.
SUB NONE turns
off the feed to the subwoofer, while
SUB
<L+R> turns it on.
4. When the desired setting has been entered,
press the OK Button
F
@
to return to
normal operation.
Stereo-Digital Mode
When the Stereo-Direct (Bypass) mode is in use a
full range signal is always sent to the front
left/right speakers. By its nature, that option does
not pass the signal through the AVR’s digital
signal processing, creating the requirement for
full-range speakers. If your front speakers are
bandwidth limited, “satellite”speakers, we
recommend that you do NOT use the Bypass
mode, but rather use the
DSP SURROUND
OFF
mode for stereo listening.
To listen to programs in the two-channel stereo
mode while taking advantage of the bass
management system, press the Stereo Mode
Selector
S
until SURROUND OFF appears
in the Main Information Display
Ò
and the
DSP and
SURR. OFF Surround Mode
Indicators
(
both light up. When only the
SURR. OFF Surround Mode Indicators
(
is lit you are in the Stereo-Direct (Bypass) mode.
When this mode is in use, the front left/right
speakers and subwoofer may be configured to
meet the requirements of your specific speakers
using the steps shown in the Speaker Setup
section below.
The last option line in this menu is the setting to
turn the unit’s upsampling feature on or off. In
normal use, this feature is turned off, which
means that digital sources are processed at their
native sample rate. For example, a 48kHz digital
source will be processed at 48kHz. However, the
AVR allows you to upsample the incoming 48kHz
signals to 96kHz for added resolution.
To take advantage of this feature, press the

Navigation Button n so that the fi cursor is
next to the

so that ON is
highlighted in reverse video. Note that this fea-
ture is only available for the Dolby Pro Logic II-
Music, Dolby Pro Logic II-Movie,
Dolby Pro Logic and Dolby 3 Stereo modes.
Automated Speaker Setup
Using EzSet/EQ
The AVR 155 is one of the first receivers in its
class to offer automated speaker setup and sys-
tem calibration. This process greatly simplifies the
installation of your new receiver by using a series
of test signals and the power of an advanced
digital signal processing system to eliminate the
need for manual adjustment of speaker “size”,
crossover, delay and output level settings, while
adding the power of a multi-band parametric
equalizer to smooth out any peculiarities in
frequency response that may result from the char-
acteristics of the listening room. With EzSet/EQ
your new receiver even alerts you to errors in
speaker connections that prevent a speaker from
functioning.
With EzSet/EQ you are able to calibrate your
system in a fraction of the time it would take to
enter the settings manually, and with results that
