Operation
digital jacks are now an output, instead of in the default setting as an input. Once changed to an output, the setting will remain as long as the AVR 5550 is turned on, unless the setting is changed in the OSD menu system, as described above. Note, however, that once the AVR 5550 is turned off, the setting is cancelled. When the unit is turned on again, the front panel jacks will return to their normal default setting as an input. If you wish to use the jacks as an output at a future time, the setting must be changed again using the OSD menu system, as described above.
NOTES:
•The digital outputs are active only when a digital signal is present, and they do not convert an ana- log input to a digital signal, or change the format of the digital signal (e.g. Dolby Digital to PCM or vice versa, but coaxial digital signals are converted to optical signals and vice versa). In additon, the digital recorder must be compatible with the output signal. For example, the PCM digital output from a CD player may be recorded on a CD-R or MiniDisc, but Dolby Digital or DTS signals may not.
•To make an analog recording from a digital source is possible, but only from a PCM source (not Dolby Digital or DTS) and correctly only with "Surround Off" mode (with any Surround mode only the L/R front signals will be fed to the record outputs).
Output Level Adjustment
With Source Signals
Normal output level adjustment for the
AVR 5550 is established using the test tone, as outlined on page 26. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer and those for the Stereo and VMAx modes can only be adjusted using this procedure. Note that all adjustments made with any input will be effective with all inputs selected, just as it is the case with the adjustment using the test tone.
To adjust the output levels using program materi- al, first select the surround mode for which you want to trim the speakers (see NOTE below), start your program material source and set the reference volume for the front left and front right
channels using the Volume Control | î. |
Once the reference level has been set, press the Channel Select button CÙ and note that FRONT L LEVEL will appear in the Lower Display Line B. To change the level, first press the Set button F@, and then use the Selector buttons 7$ or the ⁄/ ¤ buttons
Dto raise or lower the level. DO NOT use the volume control, as this will alter the reference 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 LEVEL appears in the Main Information Display ˜or on-screen display (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 ˜ 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 5550 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 | 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 ı î. Then, press the OSD button Lto bring up the MASTER 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 channel 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 generator as the source, the goal is to have the output level at each channel be equal when heard at the listening position, with any surround mode selected. When your test source is a nor- mal 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 BACK TO MASTER MENU and then press the Set Button Fif you wish to go back to the main menu to make other adjust- ments. 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.
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.
