Harman-Kardon 347 - Manual (Page 28)

28 SYSTEM CONFIGURATION
On the DSP ( SURR ) menu, the selection
choices made with the ‹ / › Buttons Ea
on the remote select one of the DSP surround
modes that are designed for use with two-chan-
nel stereo programs to create a variety of sound
field presentations. The choices available are 5.1
or 6.1 modes of Hall 1, Hall 2 and Theater. The
Hall and Theater modes are designed for multi-
channel installations. See pages 37-38 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 presenta-
tion, or select
5 C H Stereo or 7 C H
Stereo depending on whether the 5.1 or
6.1/7.1 output is in use. The latter modes feed
the stereophonic input signal to both front
speakers, to the rear speakers and to both sur-
round back speakers (if in use), while the mono-
phonic signal parts are spread over all speakers,
also the Center. See page 37-38 for a complete
explanation of the 5 CH Stereo and 7 CH Stereo
modes.
After the selections are made in the Dolby, DTS,
Logic 7, DSP (Surround) or Stereo menus, press
the
‹ Button E to go back to the main menu.
Configuring the Surround Off
(Stereo) Modes
For superior reproduction of two-channel pro-
gram 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 pre-
serves 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 and the Surround
Mode Indicator ( for Surround Off is lit, 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 sub-
woofer turned off for this mode, but you may
change that setting by following these steps:
1. Press the Speaker Button 6 b.
2. Press the Set Button F@ to activate the
configuration menu.
3. Press the ⁄ / ¤ Buttons D on the remote
or the ‹ / › Buttons 7 on the front panel to
select the desired option. SUB NONE turns off
the feed to the subwoofer, while SUB
turns it on.
4. When the desired setting has been entered,
press the Set Button
F@ to return to nor-
mal 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 digi-
tal 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 man-
agement 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.
Automated Speaker Setup
Using EzSet/EQ
The AVR 347 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 peculiar-
ities in frequency response that may result from
the characteristics 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 sys-
tem in a fraction of the time it would take to
enter the settings manually, and with results that
rival those achieved with expensive test equip-
ment and time-consuming procedures. The end
result is a system calibration profile that enables
your new receiver to deliver the best possible
sound, no matter what type of speakers you
have or what the dimensions of your listening
room are.
We recommend that you take advantage of the
precision of EzSet/EQ to calibrate your system,
but if desired you may also make any of the con-
figuration settings manually, or trim the settings
provided by EzSet/EQ by following the instruc-
tions on pages 31 through 34.
Figure 13
If you wish to configure your AVR manually, or if
for some reason your EzSet/EQ microphone is
unavailable, you may still do so by following the
instructions on pages 31 through 34.
Step 1: EzSet/EQ requires that your listening
room have as little background noise as possible
to avoid interfering with the measurement of
tones produced by your AVR during the setup
procedure. Turn off all loud fans, air conditioners
and other equipment, and try to avoid making
any noise during the process.
