Analog Stereo

This type of recording includes any conven- tional stereo signal from the RSX-1057’s ana- log inputs, including analog audio from CD players, FM tuners, VCRs, tape decks, etc.

Analog stereo inputs require a choice about how the signal is routed through the RSX-1057. One option is the analog bypass mode. In this mode, the stereo signal is routed directly to the volume control and the outputs. It is pure 2-channel stereo, bypassing all of the digital circuitry. None of the bass manage- ment features, speaker level settings, contour settings, or delay settings are active. There is no subwoofer output. A full-range signal is sent directly to two speakers.

The other option converts the analog inputs to digital signals, passing them through the digital processors in the RSX-1057. This option allows all of the features to be active includ- ing bass management settings, crossovers, subwoofer outputs, contour settings, etc. In this mode, you can select several surround modes including 2-CH Stereo, Dolby 3-Ste- reo, 5-CH Stereo, 7-CH Stereo modes. You can also use Dolby Pro Logic II or Pro Logic IIx surround, DTS Neo:6 surround, or one of the MUSIC 1-4 DSP modes.

NOTE: In addition to the options that follow, you can select Pro Logic II Cinema, Pro Logic

IIMusic, Pro Logic IIx Cinema, Pro Logic IIx Music, 5-channel stereo, or 7-channel stereo by pressing one of the surround mode buttons on the remote (PLC, PLM, 5CH, 7CH).

•To select Stereo or Analog bypass mode for 2-channel analog re- cordings. Press the 2CH button on the remote to toggle between Stereo (with digital processing) or Analog Bypass (no digital processing) modes.

•To select any mode for 2-channel analog recordings. Press the SUR+ button on the remote, then use the +/– but- tons to step through the optional modes until the desired mode is displayed.

•To select Dolby multichannel modes for 2-channel analog recordings. You can also step through the Dolby op- tions (Pro Logic II, Pro Logic IIx, or 3-Ste- reo) by repeatedly pressing the DOLBY PLIIx/3ST button on the front panel. You

can select Pro Logic or Pro Logic IIx Cin- ema or Music modes by pressing the PLC or PLM buttons on the remote.

To change the Cinema or Music option in Pro Logic II mode, press the SUR+ but- ton the remote twice while in Pro Logic

II or Pro Logic IIx modes. Then, press the +/– buttons to select the option.

•To select DTS Neo:6 modes for 2- channel analog recordings. You can also step through the DTS options (Neo:6 Cinema or Neo:6 Music) by repeatedly pressing the DTS Neo:6 button on the front panel.

To change the Cinema or Music option in Neo:6 mode, press the SUR+ button the remote twice while in Neo:6 mode. Then, press the +/– buttons to select the option.

•To select DSP multichannel modes for 2-channel analog recordings. You can also step through the DSP options (MUSIC 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

The levels of all channels should be calibrated using the TEST TONE procedure during the initial setup of the RSX-1057. You can make a temporary change in the relative volume of the center, surround, center back, or sub- woofer 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 RSX-1057 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 ad- just 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 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 signals are out of synch. This can oc- cur with upconverted digital TV signals or when trying to match a radio broadcast with the video from a sports event. The set- tings 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 dif- ferent 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 ap- plied to all channels.

Dynamic Range

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 reduce the dy- namic 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 ef- fects. Dolby Digital dynamic compensation is a sophisticated feature that allows you to adjust the dynamic range while still preserv-
