the Selector buttons 7$ or the ⁄/ ¤ buttons Dto raise or lower the level. DO NOT use the volume control, as this will alter the ref- erence setting.
Once the change has been made, press the Set button F@ and then press the Selector but- tons 7$ or the ⁄/¤ buttons Dto select the next output channel location that you wish to adjust. To adjust the subwoofer level, press the Selector buttons 7$ or the ⁄/¤ buttons Duntil WOOFER LEV appears in the Main Information Display Yor on-screen dis- play (only available if the subwoofer is turned on).
Press the Set button F@ when the name of the desired channel appears in the Main Information Display Y and on-screen display, and follow the instructions shown above to adjust the level.
Repeat the procedure as needed until all chan- nels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for five seconds, the AVR 4500 will return to normal operation.
If you are using a disc with noise test signals or an external signal generator as the source from which to trim the output levels, you may use the EzSet feature of the remote to guide you to the correct SPL level. To use the remote for this pur- pose, start the test tone from the source and press and quickly release the SPL Indicator
Select to activate the sensor.
While the test tone is played, the Program/SPL Indicator 2will change color to indicate the level. When it is red, the level is too high; when it is orange, the level is too low. To set the refer-
ence level, open the Volume Control until the SPL Indicator´s LED lights green when the test signal is fed to the left front speaker. Then adjust the level of all other speakers, while they are receiving the test signal, until the LED lights green for all channels. After the output levels for all channels are aligned, press the SPL Indicator Select 2to turn the sensor and indicator off. Press the SPL Indicator Select
to turn the sensor and indicator off.
The channel output may also be adjusted using the full-OSD on-screen menu system. First, set the volume to a comfortable listening level using the Volume Control Ù î. Then, press the OSD button Lto bring up the MAS- TER MENU (Figure 1). Press the ¤ Button Dfour times until the on-screen › cursor is next to the CHANNEL ADJUST line. Press the Set Button Fto activate the CHANNEL ADJUST menu (Figure 10).

When the menu appears, the internal test tone will be turned off. This will allow you to use your external test disc or other source material as the test signal. Then, use the ⁄/ ¤ Buttons Dto select the channels to be adjusted. At each chan- nel position use the ‹/ › Buttons E to change the output level.
Remember, when you are using a disc with test signal (e.g. pink noise) or an external signal gen- erator as the source, the goal is to have the out- put level at each channel be equal when heard at the listening position, with any surround mode selected. When your test source is a normal disc with music signals, you may adjust the level for each channel and surround mode as you prefer, e.g. you may lower the center channel level when you find it to be too high or increase the level of the rears when you find it to be too low with specific surround modes.
If you wish to reset all the levels to their original factory default of 0dB offset, press the ⁄/ ¤ Buttons Dso that the on-screen cursor is next to the CHANNEL RESET line and press the ‹/ › Buttons E so that the word ON is highlighted. After the levels are reset, resume the procedure outlined above to reset the levels to the desired settings. When all adjustments are done, press the ⁄/ ¤ Buttons Dto move the on-screen › cursor so that it is next to RETURN TO MASTER MENU and then press the Set Button Fif you wish to go back to the main menu to make other adjustments. If you have no other adjustments to make, press the OSD Button Lto exit the menu system.
NOTE: The output levels may be separately trimmed for each digital and analog surround mode. If you wish to have different trim levels for a specific mode, select that mode and then follow the instructions in the steps shown above.
With Stereo and Vmax modes the adjustment procedure described above is the only way to trim the output level, e.g. to match the Stereo or Vmax level with other modes.
6-Channel/8-Channel Direct Input
The AVR 4500 is equipped for future expansion through the use of optional, external adapters for formats that the AVR 4500 may not be capable of processing or to allow connection to the out- put of high-resolution optical audio playback sys- tems such as DVD-Audio or SACD. When a device with six-channel outputs (5.1 audio) is used, con- nect the source device to the 6-Channel Direct Inputs . When a device with eight-channel outputs (7.1) audio is used, connect the addition- al Surround Back Left (SBL) and Surround Back Right (SBR) outputs to the 8-Channel Direct Inputs on the AVR. To select these inputs, press the 6-Channel/8-Channel Direct Button 7on the remote or the Input Source Selector % on the front panel until the desired input configuration appears in the Main Information Display Y.
Note that when the 6-Channel or 8-Channel Direct Input is in use, you may not select a sur- round mode, as the external decoder determines the processing in use. In addition, there is no sig- nal at the record outputs or bass management when the 6-Channel or 8-Channel Direct Input is in use and the tone or balance controls will not function.
Memory Backup
This product is equipped with a memory backup system that preserves tuner presets and system configuration information if the unit is turned off completely, accidentally unplugged or subjected to a power outage. This memory will last for approximately two weeks, after which time all information must be reentered.
