6.During the adjustment, you will see the location of the channel position being adjusted appear in the on-screen display (if connected) and in the Lower Display Line ¯, alternating with a read- out of the output setting, relative to the reference volume level, and in the Speaker/Channel Input Indicators ˆ where the letters for the channel being adjusted will flash to indicate the channel from which the test tone should be heard. As the adjustment proceeds, a few things will happen simultaneously:
•The channel position being adjusted will flash in the Speaker/Channel Input Indicators ˆ. If the test noise is heard from a channel other than the one shown in the indicator, there is an error in the speaker connections. If this is the case, press the Test Button i TWICE to stop the adjustment. Then, turn the unit off and verify that all speakers are connected to the proper Outputs ª‚⁄¤.
•As the individual channels are set, the channel name and the adjustment offset will appear in the on-screen display (if connected) and the Lower Display Line ¯. While the level is changing, the Program/SPL Indicator c will change colors to reflect the output level in rela- tion to the reference. A red indication shows that the level is too high, while an amber indica- tion shows that the level is too low. When the indicator is green, the level is correct, and the test noise will move to the next channel.
•While adjustments are being made, the red LED under the AVR Selector f will flash. This is normal, and indicates that EzSet is operating.
7.After the test noise has circulated once through each channel, it will send the tone to each chan- nel once again, to verify the settings.
8.After two complete circulations of the tone, the levels are set. The Program/SPL Indicator c will remain green at each channel. Upon comple- tion of the second circulation, the Program/SPL Indicator c will flash green twice and then go out. The tone will stop and the AVR 230 will return to normal operation.
If you find that the output levels chosen by EzSet are either uncomfortably low or high, you may repeat the procedure. Return to Step 2 and adjust the master volume either slightly higher or lower to accommodate your particular room layout and your tastes. You may repeat this procedure as many times as necessary to achieve a desired result. In order to prevent possible damage to your hearing or your equipment, we emphasize that you should avoid setting the master volume above 0dB.
NOTE: The subwoofer output is not adjusted when the test tone is in use. To adjust the subwoofer output you must use an external source, following the instructions on page 29.
Manual Output Level Adjustment
Output levels may also be adjusted manually, either to set them to a specific level with an SPL meter, or to make fine-tuning adjustments to the levels obtained using the EzSet remote.

Figure 8
Manual output level adjustment is most easily done through the CHANNEL ADJUST menu (Figure 8). If you are already at the MASTER MENU, press the ¤ Button n until the on- screen › cursor is next to the CHANNEL ADJUST line. If you are not at the MASTER MENU, press the OSD Button v to bring up the MASTER MENU (Figure 1), and then press the
¤Button n until the on-screen › cursor is next to the CHANNEL ADJUST line. Press the Set Button p to bring the CHANNEL ADJUST menu (Figure 8) to the screen.
When the CHANNEL ADJUST menu appears, press the ¤ Button n until the on-screen
›cursor is next to the TEST TONE line. Press the ‹/› Buttons o so that ON is shown and the AVR’s internal test tone will begin to circulate from speaker to speaker in a clockwise direction into all speakers. The test noise will play for two seconds in each speaker before circulating, and a blinking on- screen cursor will appear next to the name of each speaker location when the sound is at that speaker.
NOTES:
•Remember to verify that the speakers have been properly connected. As the test noise circulates, listen to make certain that the sound comes from the speaker position shown in the on-screen display and by the flashing indication in the Speaker/Channel Input Indicators ˆ. If the sound from a speaker location does NOT match the position indicated in the display, turn the AVR 230 off using the Main Power Switch 1 and check the speaker wiring or connections to external power amplifiers to make certain that each speaker is
connected to the correct output terminal.
•Remember that when your system has only a single Surround Back speaker and is thus configured for 6.1-channel operation, you will hear the test tone twice from the back speaker, once with the SBL indication and once with the SBR indication. This is normal, and it allows you to adjust the output bal- ance for the mixing circuit that creates a 6.1 output when 7.1 modes such as Logic 7/7.1 are used.
After checking for speaker placement, let the test noise circulate again, and listen to see which channels sound louder than the others. Using the front left speaker as a reference, press the ‹/› Buttons o on the remote to bring all speakers to the same vol- ume level. When one of the ‹/› Buttons o is pushed, the test noise circulation will pause on the channel being adjusted to give you time to make the adjustment. When you release the button, the circula- tion will resume after five seconds.
Continue to adjust the individual channels until the volume level sounds the same from each speaker. Adjustments should be made with the ‹/› Buttons
oon the remote only, NOT the main volume con- trols. If you are using a sound-pressure level (SPL) meter for precise level adjustment, set the volume so that the meter reads 75dB, C-Weighting Slow.
You may also adjust the output levels manually while using the level indication feature of the EzSet remote. To activate the sensor and indicator, simply press and release the SPL Selector Button 40 on the remote while the test tone is circulating. The Program/SPL Indicator c will change color to indicate the level. Adjust the level using the ‹/› Buttons o until the LED lights green for all channels. When it is red, the level is too high; when it is amber, the level is too low. Press the SPL Selector Button 40 when you are finished to turn the sensor and indicator off.
NOTE: The subwoofer level is not adjustable when the normal test tone is in use. The subwoofer output level may also be adjusted when the channel levels are being trimmed to a program source rather than the test tone, as shown on page 29.
When all channels have an equal volume level, the adjustment is complete. To exit this menu, press the ⁄/¤ Buttons n until the on-screen › cursor is next to the BACK TO MASTER MENU line, and then press the Set Button p to return to the
MASTER MENU.
The output levels may also be adjusted at any time using the remote control and semi-OSD system. To adjust the output levels in this fashion, press the Test Button i. As soon as the button is pressed, the test tone will begin to circulate as indicated earlier. The
