26 SYSTEM CONFIGURATIONOn the DSP (SURR) menu, the selectionchoices made with the ‹/› Buttons Eon the remote select one of the DSP surroundmodes that are designed for use with two-chan-nel stereo programs to create a variety of soundfield presentations. The choices available are 5.1or 6.1 modes of Hall 1, Hall 2 and Theater. TheHall and Theater modes are designed for multi-channel installations. See pages 37-38 for acomplete explanation of the DSP surroundmodes. Note that the Hall and Theater modesare not available when a Dolby Digital or DTSsoundtrack is played.On the STEREO menu, the selection choicesmade with the ‹/› Buttons E on theremote may either turn the surround processingoff for a traditional two-channel stereo presenta-tion, or select 5 C H Stereo or 7 C HStereo depending on whether the 5.1 or6.1/7.1 output is in use. The latter modes feedthe stereophonic input signal to both frontspeakers, to the rear speakers and to bothsurround back speakers (if in use), while themonophonic signal parts are spread over allspeakers, also the Center. See page 35-36 for acomplete explanation of the 5 CH Stereo and7 CH Stereo modes.After the selections are made in the Dolby, DTS,Logic 7, DSP (Surround) or Stereo menus, pressthe ‹ Button E to go back to the main menu.Configuring the Surround Off(Stereo) ModesFor superior reproduction of two-channelprogram materials, the AVR offers two Stereomodes: an analog Stereo-Direct mode thatbypasses the digital signal processing circuitryfor a completely analog signal path thatpreserves the purity of the original signal, and adigital mode that is capable of providing bassmanagement for optimal distribution of the lowfrequencies between smaller speakers and asubwoofer.Stereo-Direct (Bypass) ModeWhen the analog Stereo-Direct mode is selectedby pressing the Stereo Mode Selector until SURROUND OFF appears in the MainInformation Display Ò and the SurroundMode Indicator ( for Surround Off is lit, theAVR will pass the analog source material directlythrough to the front left and right speakers,bypassing the digital processing circuitry.In this mode, the front left and right speakerswill automatically be configured as LARGE; itis not possible to configure these speakers asSMALL.When the AVR is in the Stereo Bypass mode youmay still configure the subwoofer output so thatit is either turned off, with a full-range signalgoing to the front left/right speakers, or you mayconfigure it so that the subwoofer feed isactivated.The factory default setting is to have thesubwoofer turned off for this mode, but you maychange that setting by following these steps:1. Press the Speaker Button 6 .2. Press the Set Button F@ to activate theconfiguration menu.3. Press the ⁄/¤ Buttons D on the remoteor the ‹/› Buttons 7 on the front panel toselect the desired option. SUB NONE turns offthe feed to the subwoofer, while SUB turns it on.4. When the desired setting has been entered,press the Set Button F@ to return tonormal operation.Stereo-Digital ModeWhen the Stereo-Direct (Bypass) mode is in usea full range signal is always sent to the frontleft/right speakers. By its nature, that optiondoes not pass the signal through the AVR’sdigital signal processing, creating therequirement for full-range speakers. If your frontspeakers are bandwidth limited,“satellite”speakers, we recommend that you doNOT use the Bypass mode, but rather use theDSP SURROUND OFF mode for stereolistening.To listen to programs in the two-channel stereomode while taking advantage of the bassmanagement system, press the Stereo ModeSelector until SURROUND OFFappears in the Main Information Display Òand the DSP and SURR. OFF SurroundMode Indicators ( both light up. When onlythe SURR. OFF Surround ModeIndicators ( is lit you are in the Stereo-Direct(Bypass) mode.When this mode is in use, the front left/rightspeakers and subwoofer may be configured tomeet the requirements of your specific speakersusing the steps shown in the Speaker Setupsection below.Automated Speaker SetupUsing EzSet/EQThe AVR 247 is one of the first receivers in itsclass to offer automated speaker setup andsystem calibration. This process greatly simplifiesthe installation of your new receiver by using aseries of test signals and the power of anadvanced digital signal processing system toeliminate the need for manual adjustment ofspeaker “size”, crossover, delay and output levelsettings, while adding the power of a multi-bandparametric equalizer to smooth out anypeculiarities in frequency response that mayresult from the characteristics of the listeningroom. With EzSet/EQ your new receiver evenalerts you to errors in speaker connections thatprevent a speaker from functioning.With EzSet/EQ you are able to calibrate yoursystem in a fraction of the time it would take toenter the settings manually, and with results thatrival those achieved with expensive testequipment and time-consuming procedures. Theend result is a system calibration profile thatenables your new receiver to deliver the bestpossible sound, no matter what type of speakersyou have or what the dimensions of yourlistening room are.We recommend that you take advantage of theprecision of EzSet/EQ to calibrate your system,but if desired you may also make any of theconfiguration settings manually, or trim the set-tings provided by EzSet/EQ by following theinstructions on pages 31 through 34.Figure 13If you wish to configure your AVR manually, or iffor some reason your EzSet/EQ microphone isunavailable, you may still do so by following theinstructions on pages 31 through 34.Step 1: EzSet/EQ requires that your listeningroom have as little background noise as possibleto avoid interfering with the measurement oftones produced by your AVR during the setupprocedure. Turn off all loud fans, air conditionersand other equipment, and try to avoid makingany noise during the process.System Configuration
