OPERATION

Now that you have installed your system components and completed
at least a basic configuration of your receiver, you are ready to begin
enjoying your home theater system.

Turning On the AVR 154

Gently press the Master Power Switch until the word OFF is no longer
visible. The Power Indicator above the two power switches should light up
in amber. This indicates that the AVR is in Standby mode and is ready to
be turned on. Normally, you may leave the Master Power Switch in the
ON position, even when the receiver is not being used. See Figure 38.

There are several ways in which the AVR 154 may be turned on:

a) Press the Standby/On Switch on the front panel. See Figure 38.

b) Press the Source Select Button on the front panel. See Figure 39.

c) Using the remote, press any one of these buttons: AVR, DVD, CD,

TAPE, AUX, HDMI 1, HDMI 2, HDMI 3, VID1, VID2, VID3, AM/FM
or 6CH. See page 13.

NOTE:

Any time you press one of the remote’s Input Selectors,

the remote will switch modes so that it will only operate that
device. To control the receiver, press the AVR Button to return
the remote to AVR mode.

To turn the receiver off, press either the Standby/On Switch on the
front panel, or press the AVR Button and the OFF Button on the remote.
Unless the receiver will not be used for an extended period of time
(for example, if you will be on vacation), it is not necessary to turn off
the Master Power Switch. When the Master Power Switch is turned off,
any settings you have programmed, including system configuration and
preset radio stations, will be preserved for up to four weeks.

Sleep Timer

You may program the AVR to play for up to 90 minutes and then turn
off automatically using the sleep timer.

Press the Sleep Button on the remote, and the time until turn-off will be
displayed. See Figure 51. Each additional press of the Sleep Button will
reduce the time until turn-off by 10 minutes, until the OFF setting is
reached, which disables the sleep timer.

Figure 51 – Sleep Button

When the sleep timer has been set, the front-panel display will automati-
cally dim to half-brightness. If you press any button on the remote or
front panel, the display will return to full-brightness. The display will dim
again several seconds after your last command.

If you press the Sleep Button after the timer has been set, the remaining
time until turn-off will be displayed. You may press the Sleep Button to
change the time until turn-off. Press and hold the Sleep Button to turn
the sleep timer off.

Volume Control

The volume may be adjusted either by turning the knob on the front
panel (clockwise to increase volume or counterclockwise to decrease
volume), or by pressing the Volume Control Buttons on the remote.
See Figure 52. The volume is displayed as a negative number of
decibels (dB) below the 0dB reference point.

Unlike the volume controls on some other products, 0dB is the maximum
volume for the AVR 154. Although it’s physically possible to turn the
volume to a higher level, doing so may damage your hearing and your
speakers. For certain more dynamic audio materials, even 0dB may be
too high, allowing for damage to equipment.

Figure 52 – Volume Controls

The AVR 154 is designed to reproduce audio with a minimum amount
of distortion, which 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. See Figure 53. 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.

Press the Tone Mode Button once. See Figure 54. This will indicate
whether the tone controls are in or out of the circuitry. 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.
