Other Settings

Speaker Level

The levels of all channels should be calibrated using the TEST TONE procedure during the initial setup of the RSX-1056. 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 dif- ferent input is selected or until the RSX-1056 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 adjust- ment. Press the C button to adjust the CEN- TER 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 se- lected speaker and its current setting appear briefly in the display.

2.Use the UP or DOWN buttons on the re- mote to adjust the output level of the se- lected channel(s).

NOTE: If no level adjustment is made for 10 seconds, the levels revert to the default cali- brated settings.

As you select a speaker in the above adjust- ments, you may notice an addition choice, “group delay”. See the following for an ex- planation of this feature.

Group Delay

The SPEAKER adjustments (described above) can also be used to make a temporary ad- justment 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 sig- nals 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 5 ms increments.

Like the speaker settings, this is a temporary adjustment that overrides the permanent de- fault setting for a video source until a differ- ent input source is selected or the unit is turned off.

To adjust group delay using the re- mote:

1.Press the C button on the remote twice.

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

Dynamic Range

Dolby Digital recordings are capable of wide dynamic range (the difference between the soft- est and loudest sounds). In some cases, this may tax amplifiers and/or speakers. In other cases, you may want to 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 fea- ture that allows you to adjust the dynamic range while still preserving fidelity. The actual amount of compression relies on instructions embed- ded in the Dolby Digital recording and var- ies to best suit the specific program content.

There are three dynamic range settings avail- able 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 typi- cal VHS Hi-Fi recording.

To adjust dynamic range:

Press the DYN button on the remote repeat- edly 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 fea- ture is only available in Dolby Digital mode. The setting is ignored with all other types of recordings.
