Harman-Kardon AVR 355, AVR 255 owner manual Adjust Speaker Distance Menu

System Configuration

Adjust Speaker Distance Menu

As explained above in Step Two – Measure Speaker Distances, sometimes the speakers are placed at different distances from the listening- position, which can muddy the sound, as sounds are heard earlier or later than desired.

Even if all of your speakers are placed the same distance from the listening position, do not skip this menu.

On the Manual Speaker Setup menu, move the cursor to the Distance line and press the OK Button to display the Adjust Speaker Distance menu. See Figure 12.

Figure 12 – Adjust Speaker Distance Menu

This menu requires you to enter the distance from each speaker to the listening position, which you measured in Step Two – Measure Speaker Distances and noted in TableA3 in the appendix.

The default unit of measurement is feet. If you wish to change the unit to meters, press the Back/Exit Button until you return to the main AVR menu. Scroll down to the System line, and select it to view the System Settings menu. Scroll down this menu to the General AVR Settings section, and select the Unit of Measure line. Press the OK Button to change the setting from Feet to Meters.

Use the K/L Buttons to move the cursor to the Front Left line, press the OK Button then use the M/N Buttons to change the measurement as needed. The values vary between 0 and 9 meters, with a default of 3 meters for all speak- ers. Use the M/N Buttons to move to each speaker in turn – Center,Front Right, Surround Right, Surround Back Right, Surround Back Left, Surround Left and Subwoofer,if present in your system.

NOTE: When the multiroom system is in use, the surround back channels are automatically assigned to the multiroom system, as mentioned earlier.You will not be able to adjust the delay settings for these channels, and the cursor will skip past them.

Step Four – Setting Channel Output Levels Manually

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

With up to seven main channels plus a sub- woofer, imaging becomes both more critical and more complex. Unlike the rotary balance control, the goal of the AVR 355/AVR 255’s channel out- put 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 the Initial Setup section, then you let EzSet/EQ handle this critical task for you, simply and automatically.

However,if you prefer to make these adjust- ments manually, the AVR 355/AVR 255’s Adjust Speaker Levels 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 a handheld SPL meter (available at most electronics stores) set to the C-Weighting, Slow scale.

1.Make sure all speakers have been connected correctly.

2.Adjust the number of speakers, crossover dis- tance and submode for each speaker in your system as described in Step Three.

3.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.

4.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 two ways:

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

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

The best method of setting the output levels is by running EzSet/EQ, as described in the Initial Setup section. If any finer adjustments are desired, we recommend using the menu system to make the adjustments while playing the AVR’s built-in test tone and measuring the output using an SPL meter. Less effective would be to measure the output by ear. Press the AVR Button to display the menu system, and then navigate to the Speaker Setup line. Press the OK Button to display the Speaker Setup menu. Select Manual Speaker Setup, press the OK Button, and then navigate to the Level Adjust line. Press the OK Button to display the Adjust Speaker Levels menu. See Figure 13.

All of the speaker channels will appear with their current level settings.
