Rotel RSX-1067 Other Settings, Speaker Level, Group Delay, Dynamic Range, Contour/Tone Settings

Other Settings

Speaker Level

The levels of all channels should be calibrated using the TEST TONE procedure during the initial setup of the RSX-1067. 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-1067 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.

Contour/Tone Settings

The contour controls (available on the front panel and the remote control) can be used to make a temporary change the high or low fre- quency content at the frequency extremes. Adjustments to the contour settings are tem- porary; they remain in effect only until a dif- ferent 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 fre- quency contour (HF) increases or decreases the treble. Changing the low frequency con- tour (LF) increases or decreases the bass con- tent. 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. Ei- ther LF or HF appears in the OSD and front panel displays, depending on which ad- justment is currently active. Press the TONE button again to toggle to the other adjust- ment.

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

To adjust the contour settings from the front panel:

1.Turn the LF knob to increase or decrease the low frequency contour.

2.Turn the HF knob to increase or decrease the high frequency contour.

Permanent contour adjustments for all speak- ers or for any group of speakers (front, cen- ter, surround, etc.) can also be made from the Contour Settings OSD menu in the Setup sec- tion of this manual.

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