Setting Channel Output Levels Manually

For a conventional 2-channel receiver, the balance control enables the user to control the stereo imaging by adjusting the relative loudness of the left and right channels, as heard at the listening position.

With five main channels plus a subwoofer, imaging becomes both more critical and more complex. Unlike the rotary balance control, the goal of the AVR 145’s channel output adjustment process is to examine the output level of each channel independently and ensure that each is heard at the listening position with equal loudness.

If you followed the instructions in Step Four of the Initial Setup section, then you let EzSet handle this critical task for you, simply and auto- matically.

However, if you prefer to make these adjustments manually, the

AVR 145’s Channel Adjust menu allows you to do so, either using the system’s test tone or while playing source material. In addition, this is the only method for adjusting the level of the subwoofer.

You may use either the EzSet remote or a handheld SPL meter (avail- able at most electronics stores) set to the C-Weighting, Slow scale.

1.Make sure all speakers have been connected correctly.

2.Use the Speaker Size menu, or press the Speaker Setup Button on the remote, to make sure the correct speaker size has been entered for each speaker in your system.

3.Use the Speaker X-over menu to program the correct crossover setting for each speaker in your system.

4.Use the Delay Adjust menu, or press the Delay Button on the remote control, to enter the distance between each speaker and the listening position.

5.If you are using a handheld SPL meter with source material, such as a test disc or another audio selection, play it now and adjust the AVR’s master volume control until the meter measures 75dB.

6.If you are using the EzSet remote, either set the master volume to –15dB, or you may play source material and press the SPL Button once. Adjust the volume until the LED turns green. If it’s amber, the volume is too low; if it’s red, the volume is too high.

7.There are several methods of adjusting the channel output levels, using either the test tone or source materials. In all cases, you may measure the channel levels in one of three ways:

a)By ear. Try to adjust the levels so that all channels sound equally loud.

A. Using the Remote Control With the Test Tone

While sitting in the listening position, press the Test Button on the remote. The test tone will start playing at the front left channel. After a few seconds, it will move to the center channel, then the front right channel, surround right, surround left and finally the subwoofer, display- ing the channel name on the front of the receiver and in the semi-OSD display, as well as the current level setting (varies between –10dB and +10dB). Press the ⁄/¤ Buttons to adjust the level setting, and the tone will remain at that channel until several seconds after your last adjustment. When you have finished adjusting the levels, press the Test Button again to stop the tone. Measure the levels by ear, using an SPL meter, or using the remote, as described above.

B. Using the Front-Panel Controls

You may adjust the levels by pressing the Channel Button on the front panel, and the FRONT L LEVEL message will appear. Use the ‹/› Buttons on the front panel to select the desired speaker channel to adjust, and press the Set Button when the desired channel is displayed. The current level for that channel will appear, and you may adjust it using the ‹/› Buttons. Press the Set Button to return to the speaker channel choices. This method is not recommended, as you will not be able to measure the channel levels at the listening position. In addition, this method requires that a source is playing.

C. Using the Full-OSD Menu

Next to EzSet, the full-OSD menu system offers the easiest and most flexible manner of setting output levels. Press the OSD Button to display the Master Menu, and then navigate to the MANUAL SETUP line. Press the Set Button to display the Manual Setup menu, and then navigate to the CHANNEL ADJUST line. Press the Set Button to display the Channel Adjust menu.

b)Using a handheld SPL meter set to the C-Weighting, Slow scale. Try to adjust each channel so that the meter reads 75dB.

c)Using the AVR 145 remote, press the SPL Button once so that the LED lights steadily. When it’s amber, the level is too low and should be raised. When the LED is red, the level is too high and should be low- ered. When the LED is green, the level is correct.

All of the speaker channels will appear at the top of the screen with their current level settings. Any channels that have not been programmed using the Speaker Size menu will display four dashes and will not be accessible.

CHANNEL RESET: If you wish to start by resetting all of the levels to their factory defaults of 0dB, navigate to this line and change the setting to ON. The levels will be reset, and this setting will then revert to OFF.
