AVR145
OPERATION
Remember that the AVR 145 is designed to reproduce audio with a
minimum amount of distortion. This clarity may lead you to think that
your hearing and the equipment can handle higher volumes. We urge
caution with regard to volume levels.

Mute Function

To temporarily mute all speakers and the headphones, press the Mute
Button on the remote. Any recording in progress will not be affected.
The MUTE message will flash in the display as a reminder. To restore
normal audio, either press the Mute Button again, or adjust the volume.
Turning off the AVR will also end muting.

Tone Controls

You may boost or cut either the treble or the bass frequencies by up
to 10dB in 2dB increments.
Using the front-panel controls or the remote, press the Tone Mode
Button once. 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 preserves any changes you have made to the bass or
treble settings for later use. To reactivate your changes, the tone control
must again be set to TONE IN.
With the TONE IN message displayed, press the Tone Mode Button
repeatedly to access TREBLE MODE and BASS MODE. Use the ‹/›
Buttons to change the treble or bass settings, as desired. The display
will return to normal a few seconds after your last command.

You may alternatively adjust the tone controls using the full-OSD menu
system. Press the OSD Button on the remote to view the Master Menu.
The cursor will be pointing to the INPUT SETUP line; press the Set
Button to display that menu. You will be able to view the tone settings. If
you 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 you
wish to change. Once you have changed the setting using the ‹/›
Buttons, simply move the cursor up or down to a different line; it isn't
necessary to press the Set Button to enter the new setting. When you
have finished, either wait until the display times out and disappears,
press the OSD Button to clear the display, or move the cursor to the
32
BACK TO MASTER MENU line if you wish to make other changes using
the menu system.
NOTE: The AVR 145 does not have any conventional balance
control. The EzSet process compensates for any characteristics
of your room or speakers, and we recommend that you leave
the settings as they are after EzSet has been run. However, you
may 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.

Headphones

Plug the 1/4" plug on a pair of headphones into the headphone jack on
the front of the receiver for private listening. The first time you use the
headphones, the DOLBY H:BP message will be displayed, indicating that
Dolby Headphone surround processing is in the bypass mode, which
delivers a conventional 2-channel signal to the headphones.
Figure 51 – Headphone Jack
Press the Surround Select Button on the front panel, or the Dolby
Button on the remote, to switch to Dolby Headphone virtual surround
processing, indicated by the DOLBY H:DH message. Dolby Headphone
delivers an enhanced sound field that emulates a 5.1-channel speaker
system. No other surround modes are available for the headphones.

Source Selection

Press the front-panel Source Select Button to scroll through the
sources. The left side of the button scrolls down the list that appears in
the display; the right side scrolls upward. For direct access to the tuner,
press the Tuner Band Button, which switches to the last-used band and
frequency. For direct access to any source, press its Input Selector on
the remote (see Figure 46).

NOTE: The Bridge/DMP source has no icon in the Source
Indicators display. When selected, the DMP indication will
appear in the message display's upper line, and one of two
messages will scroll on the right side to indicate whether
The Bridge is unplugged or connected. If you have retitled this
source, then only the new name will appear in the upper line.
The AVR 145 will switch to the audio and video inputs assigned to that
source. If you set the BASS MGR setting in the Speaker X-over menu to
