zHints for adjusting the parameters

• Wall material simulation (WALL)

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 affect the frequency response of the reflected sound. The WALL parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (SOFT), or harder (HARD) wall. The midpoint designates a neutral wall (made of wood).

•Seat position simulation (SEAT) (FRONT/REAR and LEFT/RIGHT)

If you sit in the front of a room, you hear more direct sound from the front speakers. As you move to the rear, the reflected sound increases. Similarly, the reflected sound changes when you move from left to right, and vice versa.

The FRONT/REAR and LEFT/RIGHT parameters let you control the balance of direct and reflected sound to simulate your listening position.

In the FRONT/REAR parameter, “F” signifies the front of the room and “R” signifies the rear. The midpoint designates the center.

In the LEFT/RIGHT parameter, “L” signifies the left side of the room and “R” signifies the right side. The midpoint designates the center.

•Reverberation time (REVERB)

This parameter adjusts the length of time required for the reverberation (echoes) generated from a given sound to attenuate –60 dB.

You can choose shorter (S) or longer (L) reverberation times.

•Low Frequency Extension (LFE) mix level (OTHER)

This parameter lets you attenuate the level of the LFE (Low Frequency Extension) 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 bass redirection circuitry. The level can be adjusted in 0.5 dB steps from –20.0 dB to 0 dB (line level). 0 dB outputs the full LFE signal at the mix level determined by the recording engineer. Selecting MUTE 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 22).

Sound Adjustment

•Dynamic range compression ratio (OTHER)

Lets you compress the dynamic range of the sound track. This may be useful when you want to watch movies at low volumes late at night.

OFF reproduces the sound track with no compression. STD reproduces the sound track with the full dynamic range as intended by the recording engineer.

0.1 ~ 0.9 allow you to compress the dynamic range in small steps to achieve the sound you desire.

MAX provides a dramatic compression of the dynamic range.

•Test tone (TEST)

This parameter emits the test tone and allows you to check the balance of the speaker levels. See “Adjusting the speaker volume” on page 23 for details.
