33OPERATIONRemember that the AVR 144 is designed to reproduce audio with aminimum amount of distortion. This clarity may lead you to believe thatyour hearing and the equipment can handle higher volumes. We urgecaution with regard to volume levels.Mute FunctionTo temporarily mute all speakers and the headphones, press the MuteButton on the remote. See Figure 46. Any recording in progress will notbe affected. The MUTE message will flash in the display as a reminder.To restore normal audio, either press the Mute Button again, or adjustthe volume. Turning off the AVR will also end muting.Figure 46 – Mute ButtonTone ControlsYou may boost or cut either the treble or the bass frequencies by upto 10dB in 2dB increments.Using the remote, press the Tone Mode Button once. See Figure 47.This will indicate whether the tone controls are in or out of the circuitry.If you wish to return the tone controls to 0, or “flat” response, press the⁄/¤ Buttons until the TONE OUT message appears, which preservesany changes you have made to the bass or treble settings for later use.To reactivate your changes, the tone control must again be set toTONE IN.With the TONE IN message displayed, press the Tone Mode Buttonrepeatedly to access TREBLE MODE and BASS MODE. Use the⁄/¤ Buttons to change the treble or bass settings, as desired. Thedisplay will return to normal a few seconds after your last command.Figure 47 – Tone ButtonYou may alternatively adjust the tone controls using the full-OSD menusystem. Press the OSD Button on the remote to view the Master Menu.The cursor will be pointing to the INPUT SETUP line; press the SetButton to display that menu. You will be able to view the tone settings. Ifyou wish to make any changes to the TONE, BASS or TREBLE settings,use the arrow keys on the remote to move the cursor to the line youwish to change. Once you have changed the setting using the ‹/›Buttons, simply move the cursor up or down to a different line; it isn’tnecessary to press the Set Button to enter the new setting. When youhave finished, either wait until the display times out and disappears,press the OSD Button to clear the display, or move the cursor to theBACK TO MASTER MENU line if you wish to make other changes usingthe menu system.NOTE: The AVR 144 does not have any conventional balancecontrol. The output level calibration process compensates for anycharacteristics of your room or speakers, and we recommendthat you leave the settings as they are after the speakers havebeen calibrated. However, you may manually adjust the levels ofthe left and right channels – decreasing one and increasing theother by the same amount – using the Channel Adjust submenu.This achieves the 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 48. Thefirst time you use the headphones, the DOLBY H:BP message will bedisplayed, indicating that Dolby Headphone surround processing is inthe bypass mode, which delivers a conventional 2-channel signal tothe headphones.Figure 48 – 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.
