Operating Your AVR

c)  when you have finished, select “Apply & Save,” and press the ok button. the AVr 

will refresh the network connection while it remains on. If the AVr cannot connect 

to the network using the manual settings, contact your ISp or network administrator 

for assistance.

•  Proxy Config: If you have connected the AVR’s Network connection to a proxy network, 

use the left/right buttons to set this to “on”, and use the number buttons to enter tne 

proxy network’s Ip address and port.

•  Network  Status:  This  line  indicates  the  AVR’s  current  network-connection  status 

(connected/not connected/network problem).

•  Apply & Save: Any time you make a change in any of the Network settings, the Apply & 

Save line will become available. Select this line and press the ok button. the AVr will 

go into the Standby mode. After you turn the AVr back on, the new network settings 

will be in effect.

you can also adjust the following settings independently for each source:
Title: you may change the display name for any source (except the radio). this feature 

may help you to select the correct source device even when you have forgotten which 

physical connections you used. 
1.  move the cursor to the title line and press the ok button. A block cursor will blink. 
2.  use the up/down buttons to scroll through the alphabet in upper and lower case, the 

numbers and many punctuation marks. when you have selected the desired character, 

press the right button to move to the next space. press the right button twice to leave 

a blank space. 

3.  press the ok button when you have finished.
Tone: this setting determines whether the treble and bass controls are active. when this 

line is set to out, the tone controls are out of the circuit, with no changes to the sound. 

when this line is set to In, the bass and treble frequencies are boosted or cut, depending 

upon the bass and treble settings (see below). 
Bass and Treble: boost or cut the low or high frequencies by up to 10db by using the 

left/right buttons to change the setting by 2db at a time.
Night Mode: this setting activates night mode with specially encoded dolby digital discs 

or broadcasts. night mode compresses the audio so that louder passages are reduced in 

volume to avoid disturbing others, while dialogue remains intelligible. each press of the 

right arrow button advances through the following settings:
•  Off: No compression is applied. Loud passages in the program remain as they were 

recorded.

•  Mid: Loud passages in the program are reduced moderately in volume.
•  Max: Loud passages in the program are reduced more in volume.
Record Out: this setting determines the source of the signal that appears at the Analog 

Audio rec out connectors for the cable/Sat, tV, disc, Server, Aux, game, Stb and Audio 

sources:
•  DSP Down mix: This setting outputs audio from digital audio input connections (HDMI, 

optical, coaxial) and analog audio input connections (Analog 1/2, Aux).

•  Analog: This setting outputs audio only from the analog audio input connections (Analog 

1/2, Aux).

when you’re finished, press the remote’s oSd button to turn off the on-screen menu.

now that you have installed your components and completed a basic configuration, you 

are ready to begin enjoying your home theater system.

Adjust the volume either by turning the front-panel Volume knob (clockwise to increase 

volume or counterclockwise to decrease volume) or by pressing the Volume up/down 

buttons on the remote. the volume is displayed as a negative number of decibels (db) 

below the 0db reference point.
0db is the maximum recommended volume for your AVr. Although it’s 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. use caution with regard to volume levels. 

to 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 appear in the front-

panel display as a reminder. to restore the sound, press the mute button again, or adjust 

the volume.

plug the 1/4-inch stereo plug on a pair of headphones into the front-panel phones jack 

for private listening. the default headphone surround mode for all sources except fm 

and Am is hArmAn headphone, which will emulate a 5.1-channel speaker system. the 

default surround mode for fm and Am is 2-ch Stereo. press the Surround mode button on 

the front panel or use the remote and oSd to switch between hArmAn headphone and 

2-ch Stereo. no other surround modes are available for headphone listening.

there are three different ways to select a source:
•  Press the front-panel Source Select buttons. 
•  Directly select any source by pressing its Source Selector button on the remote. 
•  Select a source from the Source Select menu in the OSD menu system.
the AVr selects the audio and video inputs you assigned to the source and any other 

settings you made during setup.
the source name and the surround mode will appear on the front panel. 

If there is no picture:
• Check the source selection.
• Check all connections for a loose or incorrect connection.
• Check the video-input selection on the TV/display device.
Additional Tips for Troubleshooting HDMI Connections
•  Turn off all devices (including the TV, the AVR and any source components).
•  Unplug the HDMI cables, starting with the cable between the AVR and the TV, and 

continuing with the cables between the AVr and each source device.

•  Carefully reconnect the cables from the source devices to the AVR. Connect the 

cable from the AVr to the tV last.

• Turn on the devices in this order: TV, AVR, source devices.
