32OPERATIONRemember that the AVR 145 is designed to reproduce audio with aminimum amount of distortion. This clarity may lead you to think 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. Any recording in progress will not be affected.The MUTE message will flash in the display as a reminder. To restorenormal audio, either press the Mute Button again, or adjust the volume.Turning off the AVR will also end muting.Figure 49 – Mute ButtonTone ControlsYou may boost or cut either the treble or the bass frequencies by upto 10dB in 2dB increments.Using the front-panel controls or the remote, press the Tone ModeButton once. This will indicate whether the tone controls are in or outof the circuitry. If you wish to return the tone controls to 0, or “flat”response, press the ‹/› Buttons until the TONE OUT messageappears, which preserves any changes you have made to the bass ortreble settings for later use. To reactivate your changes, the tone controlmust 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 to change the treble or bass settings, as desired. The displaywill return to normal a few seconds after your last command.Figure 50 – Tone ButtonYou may alternatively adjust the tone controls using the full-OSD menusystem.

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 145 does not have any conventional balancecontrol. The EzSet process compensates for any characteristicsof your room or speakers, and we recommend that you leavethe settings as they are after EzSet has been run. However, youmay manually adjust the levels of the left and right channels –decreasing one and increasing the other by the same amount –using the Channel Adjust submenu, as described on page 41.This achieves the same effect as a balance control.HeadphonesPlug the 1/4" plug on a pair of headphones into the headphone jack onthe front of the receiver for private listening.
