System Configuration
On the DSP (SURR) menu, the selection choices made with the ‹ / › Buttons E 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 E on the remote may either turn the surround processing off for a traditional two-channel stereo presenta- tion, or select 5 CH Stereo or 7 CH 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
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 | . |
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 <L+R> 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 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.
