Audio adjust function

The Audio Adjust functions are explained below.

Bass

With this function you can boost or cut low-frequency sounds output by the front speakers from Ð12 dB to +12 dB in 2 dB steps.

Treble

With this function you can boost or cut high-frequency sounds output by the front speakers from Ð12 dB to +12 dB in 2 dB steps.

Late Night (Only for Dolby Digital source)

With this function you can reduce the dynamic range of Dolby Digital source so that you can still hear quiet parts even when listening at low volume levelsÑideal for watching movies late at night when you donÕt want to disturb anyone.

Late Night = Off	no effect
Late Night = Low	small reduction in dynamic range
Late Night = High	big reduction in dynamic range

Note that the impact of the Late Night function depends on the Dolby Digital source that you are playing, and with some source there will be little or no effect.

This function is automatically cancelled when you set the HT-R420 to Standby.

Cinema Filter

When this function is on, you can soften the harshness, or brightness sometimes experienced with movie soundtracks, which are typically mixed for reproduction in a movie theater.

Panorama (Pro Logic II Music)

When this function is on, you can extend the front stereo image to the surround speakers to provide a ÒwraparoundÓ effect, especially useful when not much sound is being output by the surround speakers.

Dimension (Pro Logic II Music)

When this function is on, you can move the soundfield backward or forward.

With a setting of 3, the soundfield is in the normal position. Choose a lower setting to move the soundfield forward. Choose a higher setting to move it backward.

If the stereo image is too wide, or thereÕs too much surround information, try moving the soundfield forward to achieve a better balance. If the stereo image is too narrow, or it sounds almost like itÕs in mono, try moving the soundfield backward.

Center Width (Pro Logic II Music)

In Pro Logic II decoding, the center-channel signal is output by the center speaker. If a center speaker is not used, the decoder divides the center signal equally between the front left and right speakers, producing whatÕs known as a ÒphantomÓ center. With this function you can choose to have the center-channel signal output by only the center speaker, by only the front left and right speakers (ÒphantomÓ center), or by a mix of the two.

With a setting of 0, the center-channel signal is output only by the center speaker.

With a setting of 7, itÕs output only by the front left and right speakers (ÒphantomÓ center).

In home theaters, adding some width to the center channel can improve the balance between the center and front left and right speakers. Most stereo source will benefit from appropriate use of this function. The recommended setting for Pro Logic II Music mode is 3. For Pro Logic II Movie mode, the setting is automatically set to 0.
