Customizing Sound Fields
By adjusting the surround parameters and the equalization of the front and center speakers, you can customize the sound fields to suit your particular listening situation. Once you customize a sound field, the changes are stored in memory indefinitely (unless the receiver is unplugged for about one week). You can change a customized sound field any time by making new adjustments to the parameters. See the table on page 36 for the parameters available in each sound field. WALL TYPE (WALL) Initial setting : midpoint When sound is reflected off soft material, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. This parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S) or harder (H) wall. The midpoint designates a neutral wall (made of wood). REVERBERATION (REVERB) Initial setting : midpoint Before sound reaches our ears, it is reflected (reverberated) many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. This parameter lets you control the spacing of the early reflections to simulate a sonically larger (L) or smaller (S) room. � The reverberation can be adjusted ±8 from S (small, �8) to L (large, +8) in 17 steps. � The midpoint (0) designates a standard room with no adjustment. LFE (Low Frequency Effect) MIX LEVEL (LFE MIX) Initial setting : 0 dB This parameter lets you attenuate the level of the LFE (Low Frequency Effect) channel output from the sub woofer without effecting the level of the bass frequencies sent to the sub woofer from the front, center or rear channels via the Dolby Digital (AC-3) bass redirection circuitry. � The level can be adjusted in 1 dB steps from �20 dB to 0 dB (line level). 0 dB outputs the full LFE signal at the mix level determined by the recording engineer. � Selecting MUTING mutes the sound of the LFE channel from the sub woofer. However, the low frequency sounds of the front, center, or rear speakers are output from the sub woofer according to the settings made for each speaker in the speaker setup (page 15).

To get the most from multi channel surround sound
Position your speakers and do the procedures described in �Multi-Channel Surround Setup� starting on on page 14 before you customize a sound field.

Adjusting the surround parameters
The SURROUND menu contains parameters that let you customize various aspects of the current sound field. The settings available in this menu are stored individually for each sound field.

Start playing a program source encoded with multi channel surround sound. Press CURSOR MODE repeatedly until the SUR indicator lights up. Press the cursor buttons (V or v) to select the parameter you want to adjust. Press the cursor buttons (B or b) to select setting you desire. The setting is entered automatically.

EFFECT LEVEL (EFFECT) Initial setting : (depends on sound mode) This parameter lets you adjust the �presence� of the current digital cinema sound surround effect.
