OPERATION

Now that you have installed and configured your system components,
you are ready to begin enjoying your home theater system.

Turning On the HS 300

When you have plugged in the HS 300, the Power Indicator surrounding
the power switch should light up in amber. This indicates that the HS 300
is in Standby mode and is ready to be turned on. See Figure 50

Figure 50 – Power Indicator and Standby/On Switch

There are several ways in which the HS 300 may be turned on:

a) Press the Standby/On Switch on the top panel. See Figure 50.

b) Press the Open/Close Button on the top panel. See Figure 50.

c) Using the remote, press any one of these buttons: TV, DISC, RADIO,

AUX, D-IN, USB 1 or USB 2. See Figure 51.

Figure 51 – Source Selectors

NOTE:

Any time you press one of the remote’s Source

Selectors (i.e., TV, DISC, RADIO, AUX, D-IN, USB 1 or USB 2),
the remote will switch modes so that it will transmit the codes
programmed to operate that device.

To turn the HS 300 off, press either the Standby/On Switch on the top
panel, or press the System OFF Button on the remote. See Figure 51.
When the HS 300 is unplugged, any settings you have programmed,
including system configuration and preset radio stations, will be
preserved for up to four weeks.

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 some volume controls on
other products, 0dB is the maximum volume for the HS 300. 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 HS 300 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. See Figure 53. Any recording in progress will not
be affected. The MUTE message will appear briefly in the display. To
restore normal audio, either press the Mute Button again, or adjust the
volume. Turning off the HS 300 will also end muting.

Tone Controls

You may boost or cut either the treble or the bass frequencies by up
to 6dB.

The tone controls are adjusted using the Audio Setup submenu as
described in Step Two of the Initial Setup section.

Press the Setup Menu button on the remote, and use the Navigation
Buttons to highlight the Audio Setup menu icon on the left side of the
screen (has picture of a gear). Press the Enter Button to view the Audio
Setup menu, and use the Navigation Buttons to highlight the Tone
Control setting. To adjust the tone controls, the Tone Control setting
must be ON. The Bass and Treble controls may then be boost or cut
as desired. See Figure 42.

If you wish to remove the tone controls from the circuit for “flat”
response without losing bass or treble settings for future use, set the
Tone Control to OFF.

NOTE:

The HS 300 does not have a conventional balance control.

The settings made using the Audio Adjustments submenu as
explained in Step Three of the Initial Setup section compensate
for any special acoustic characteristics of your room or speakers,
and we recommend that you leave the settings as they are after
you have completed the configuration process. It is possible to
manually adjust the levels of the left and right channels –
