Operation

Basic Operation

Once you have completed the setup and configu- ration of the AVR, it is simple to operate and enjoy. The following instructions should be followed for you to maximize your enjoyment of your new receiver:

Turning the AVR On or Off

When using the AVR for the first time, you must press the Main Power Switch 1 on the front panel to turn the unit on. This places the unit in a Standby mode, as indicated by the amber color of the Power Indicator 3. Once the unit is in Standby, you may begin a listening session by pressing the System Power Control 2 or the Source button % on the front panel or the AVR Selector 5B. Note that the Power Indicator 3 will turn blue. This will turn the unit on and return it to the input source that was last used. The unit may also be turned on from Standby by pressing any of the Source Selector buttons on the remote 4567BCD or the Source button % on the front panel.

To turn the unit off at the end of a listening session, simply press the System Power Control 2 on the front panel or the Power Off Button 3A on the remote. Power will be shut off to any equipment plugged into the rear panel Switched AC Outlets and the Power Indicator 3 will turn orange.

When the remote is used to turn the unit “off” it is actually placing the system in a Standby mode, as indicated by the orange color of the Power

Indicator 3.

When you will be away from home for an extended period of time it is always a good idea to completely turn the unit off with the front panel Main Power Switch 1.

NOTE: All preset memories may be lost if the unit is left turned off with the Main Power Switch 1 for more than two weeks.

Using the Sleep Timer

To program the AVR for automatic turn-off, press the Sleep Button 9 on the remote. Each press of the button will increase the time before shut down in the following sequence:

The sleep time will be displayed in the Lower Display Line ˜ and it will count down until the time has elapsed.

When the programmed sleep time has elapsed, the unit will automatically turn off (to Standby mode). Note that the front panel display will dim to one half brightness when the Sleep function is programmed. To cancel the Sleep function, press and hold the Sleep Button 9 until the infor- mation display returns to normal brightness and the Sleep indicator numbers disappear and the words SLEEP OFF appear in the Main Information Display ˜.

Source Selection

To select a source, press any of the Source Selector buttons on the remote 467 CD.

NOTE: After pressing one of the Input Selector buttons 4D to turn the unit on, press the AVR Selector 5B to have the remote control the AVR functions.

The input source may also be changed by pressing the front-panel Input Source Selector button %. Each press of the button will move the input selection through the list of available inputs.

As the input is changed, the AVR will automati- cally switch to the digital input (if selected), surround mode component video input, A/V Sync Delay and Night Mode configurations that were in effect the last time that input was used.

The front-panelVideo 4 Inputs Ô, Optical Digital 4 Input * or the Coaxial Digital 4 Input Ó may be used to connect a device such as a video game or camcorder to your home entertainment system on a temporary basis. When they are configured as outputs (see page 25) you can also connect an audio or video recorder (composite or S-Video) for recording the source selected.

As the input source is changed, the new input name will appear momentarily as an on-screen display in the lower third of the video display. The input name will also appear in the Main Information Display ˜.

When a pure audio input (CD, Tuner, Tape,

6/8 Channel Input) is selected, the last video input used remains routed to the Video Out-

puts (except from its own Video 1/ source) and Video Monitor Output . This permits simultaneous viewing and listening to different sources.

When a Video source is selected, its audio signal will be fed to the speakers and the video signal for that input will be routed to the

appropriate Monitor Output Jack

and will be

viewable on a TV monitor connected to the AVR.

If a component video source is connected to the

DVD or Video 1 or 2

Component

Inputs, it will be routed to the Component Video Outputs . Make certain that your TV is set to the proper input to view the appropriate video signal (composite, S-Video or component video.

6-Channel/8-Channel Direct Input

There are four input choices available for use with sources such as a DVD-Audio or SACD player that are connected to the 8-Channel Direct Inputs . Select the appropriate input according to the way your system and source equipment is configured:

The 6 CH DIRECT input should be used when the SBR and SBL inputs are NOT in use and the input source device has its own internal bass management system. This input passes the input from the source directly through to the volume control without any analog to digital conversion and it mutes the unused input jacks to prevent unwanted noise from interfering with system performance.

The 6 CH DVD AUDIO input should be used when the SBR and SBL inputs are NOT in use and the input source device does NOT have its own internal bass management system. When this input is in use the analog source is converted to digital so that you may use the same Quadruple Crossover bass management options for the direct input as you do with all other inputs.

This input also mutes the unused input jacks to prevent unwanted noise from interfering with system performance.

The 8 CH DIRECT INPUT should be used when an input is connected to all eight 8-Channel Direct Inputs and when the input source device has its own internal bass management system. This input passes the input from the source directly through to the volume control without any analog to digital conversion.

The 8 CH DVD AUDIO input should be used when an input is connected to all eight

8-Channel Direct Inputs and the input

source device does NOT have its own internal bass management system. When this input is in use the analog source is converted to digital so that you may use the same Quadruple Crossover bass management options for the direct input as you do with all other inputs.
