Turning off the AVR will also end muting.Figure 63 – Mute ButtonTone ControlsYou may boost or cut either the treble or the bass frequencies byup to 10dB.Using the front-panel controls or the remote, press the Tone ModeButton once. See Figure 64. This will indicate whether the tone controlsare in or out of the circuitry. If you wish to return the tone controls to 0,or “flat” response, press the ‹/› Buttons (⁄ /¤ on the remote) untilthe TONE OUT message appears, which preserves any changes youhave made to the bass or treble settings for later use. To reactivate yourchanges, the tone control must again be set to TONE IN.With the TONE IN message displayed, press the Tone Mode Buttonrepeatedly to access TREBLE MODE and BASS MODE. Use the ‹/›Buttons (⁄ /¤ on the remote) to change the treble or bass settings,as desired. The display will return to normal a few seconds after yourlast command.Figure 64 – Tone ButtonYou may alternatively adjust the tone controls using the full-OSD menusystem. Press the OSD Button on the remote to view the menu system.The Input Setup tab will be highlighted. Press the Set Button to activatethe Input Setup menu. If you wish to make any changes to the TONE,BASS or TREBLE settings, use the ⁄ /¤ keys on the remote to movethe cursor to the line you wish to change, and press the Set Button.Once you have changed the setting using the ‹/› Buttons, press theSet Button to enter the new setting. When you have finished, either waituntil the display times out and disappears, press the OSD Button to clearthe display, or move the cursor to the menu tabs on the left side of thescreen line if you wish to make other changes using the menu system.NOTE: The AVR 247 does not have a conventional balancecontrol. The EzSet/EQ process compensates for any character-istics of your room or speakers, and we recommend that youleave the settings as they are after EzSet/EQ has been run.However, you may manually adjust the levels of the left andright channels – decreasing one and increasing the otherby the same amount – using the Channel Adjust submenu,as described in the Advanced Functions section. This achievesthe same effect as a balance control.HeadphonesPlug the 1/4" plug on a pair of headphones into the headphone jackon the front of the receiver for private listening. See Figure 65. Thefirst time you use the headphones, the DOLBY H:BP message will bedisplayed, indicating that Dolby Headphone surround processing isin the bypass mode, which delivers a conventional 2-channel signalto the headphones.Figure 65 – Headphone JackPress the Surround Select Button on the front panel, or the DolbyButton on the remote, to switch to Dolby Headphone virtual surroundprocessing, indicated by the DOLBY H:DH message. Dolby Headphonedelivers an enhanced sound field that emulates a 5.1-channel speakersystem. No other surround modes are available for the headphones.Source SelectionPress the front-panel Source Select Button to scroll through thesources. The left side of the button scrolls down the list that appears inthe display; the right side scrolls upward. For direct access to the tuner,press the Tuner Band Button, which switches to the last-used band andfrequency. See Figure 66.Figure 66 – Source Select and Tuner Band ButtonsNOTE: The Bridge/DMP, HDMI and HDMI 2 sources have noicon in the Source Indicators display. When selected, the appro-priate indication will appear in the Message Display’s upper line.One of two messages will scroll on the right side to indicatewhether The Bridge is unplugged or connected. If you haveretitled this source, then only the new name will appear in theupper line.For direct access to any source, press its Input Selector on the remote(see Figure 60). Since the AVR 247 allows for more source inputdevices than the remote has buttons for, some sources are requiredto share buttons. These are the DVD and CD sources, the Tape andThe Bridge sources, and the HDMI 1 and HDMI 2 sources. The first pressof any of these three Input Selectors will select the source whose nameappears on the button (i.e., DVD, Tape or HDMI 1), as indicated by thebutton lighting up in red. Press that Input Selector again quickly to selectthe source whose name appears above the button (i.e., CD, The Bridgeor HDMI 2), and the selector will light in green to indicate that you haveselected the source whose name is printed above the button.The AVR 247 will switch to the audio and video inputs assigned to thesource. If you selected a surround mode for the source, the AVR 247will switch to that mode.
