•To select DSP multichannel modes for 2-channel analog recordings. You can also step through the DSP options (DSP 1-4, 5CH, 7CH) by repeatedly pressing the DSP button on the front panel. Directly select 5CH mode by pressing the 5CH button on the remote. Directly select 7CH mode by pressing the 7CH button on the remote.

Other Settings

Speaker Level ET

The levels of all channels should be calibrated using the TEST TONE procedure during the initial setup. You can make a temporary change in the relative volume of the center, surround, center back, or subwoofer channels using buttons on the remote control or the front-panel controls. These temporary adjustments only remain in effect until a different input is selected or until the receiver is turned off.

To adjust speaker levels using the remote:

1.Press a selection button on the remote to select a channel (or pair of channels) for adjustment. Press the C button to adjust the CENTER channel. Press the S button to adjust the SUBWOOFER channel. Press the R button to adjust the rear SURROUND or CENTER BACK channels (each press of the R button toggles between the SURROUND channels and the CENTER BACK channels). The selected speaker and its current setting appear briefly in the display.

2.Use the UP or DOWN buttons on the remote to adjust the output level of the selected channel(s).

Note: If no level adjustment is made for 10 seconds, the levels revert to the default calibrated settings.

As you select a speaker in the above adjustments, you may notice an addition choice, “group delay”. See the following for an explanation of this feature.

Group Delay ET

The SPEAKER adjustments (described above) can also be used to make a temporary adjustment to the group delay or “lip-synch” delay. Group delay delays the overall audio signal (to all speakers) by a specified amount to correct for situations where the video and audio signals are out of synch. This can occur with upconverted digital TV signals or when trying to match a radio broadcast with the video from a sports event. The settings range from 0 to 500 milliseconds in 5ms increments.

Like the speaker settings, this is a temporary adjustment that overrides the permanent default setting for a video source until a different input source is selected or the unit is turned off.

To adjust group delay using the remote:

1.Press the C button on the remote twice.

2.Use the UP or DOWN buttons on the remote to adjust the amount of delay applied to all channels.

reduce the dynamic range when listening at low volume levels. This is particularly useful in order to keep dialog loud enough to be intelligible while avoiding excessively loud sound effects. Dolby Digital dynamic compensation is a sophisticated feature that allows you to adjust

the dynamic range while still preserving fidelity. The actual amount of compression relies on instructions embedded in the Dolby Digital recording and varies to best suit the specific program content.

There are three dynamic range settings available for Dolby Digital recordings:

•MAX: full dynamic range.

•MID: slightly reduced dynamic range, roughly comparable to the signal from a compact disc.

•MIN: more heavily reduced dynamic range, but still comparable to the signal from a typical VHS Hi-Fi recording.

To adjust dynamic range: Press the DYN button on the remote repeatedly until the desired setting appears in the front-panel display. This setting remains in effect for all Dolby Digital program material until it is changed.

Note: The dynamic range compensation feature is only available in Dolby Digital mode. The setting is ignored with all other types of recordings.

Contour/Tone Settings TX

The contour controls (available on the remote control) can be used to make a temporary change to the high or low frequency content at the frequency extremes. Adjustments to the contour settings are temporary; they remain in effect only until a different source input is selected or the unit is turned off. Permanent settings can be made using the Contour Setup menu.

The settings can be adjusted up or down by a maximum of 6dB. Changing the high frequency contour (HF) increases or decreases the treble. Changing the low frequency contour (LF) increases or decreases the bass content. The changes affect only the speaker or speaker(s) selected for adjustment in the Contour Setup menu. The settings are shown on the front-panel display as you adjust them.

To adjust the contour settings from the remote:

1.Press the TONE button on the remote. Either LF or HF appears in the OSD and front-panel displays, depending on which adjustment is currently active. Press the TONE button again to toggle to the other adjustment.

2.Press the UP/DOWN buttons on the remote to increase or decrease the setting. The display will revert to normal operation following several seconds of inactivity.

Note: The tone adjustments are available for all surround modes and inputs, except the MULTI input and analog bypass mode.

Dynamic Range L

Dolby Digital recordings are capable of wide dynamic range (the difference between the softest and loudest sounds). In some cases, this may tax amplifiers and/or speakers. In other cases, you may want to

Cinema EQ K

The EQ button (remote only) activates or deactivates a special CINEMA EQ setting. This equalization may be desirable for playback of movie source material to compensate for the acoustic differences between a
