RSP-1570 Surround Sound Processor
Options menu in the Setup section of this manual for additional details 
on changing the default standby behavior.
‘Resume’ retains the last power configuration when the main power is 
switched OFF and then switched ON again. For example, if the unit is in 
operation and the main power is switched OFF, when the main power is 
switched ON, the unit will be in operation mode again.
All OFF command:
A long press of the OFF button (more than 3
seconds), from any room, sets the unit to standby.
Volume Adjustments

Selecting Inputs
Input Buttons
48A
You can select any of nine source inputs for listening and/or watching: 
CD, TUNER, TAPE, VIDEO 1, VIDEO 2, VIDEO 3, VIDEO 4, VIDEO 5, or 
MULTI INPUT (EXT on remote).
The front-panel display and the ON-SCREEN DISPLAY show the name of 
the current listening source selection. The labels for VIDEO sources can 
be customized to match your components.
All of the source inputs can be customized using the ON-SCREEN 
DISPLAY configuration menus to accept either analog signals or digital 
signals from one of the seven assignable digital inputs, or HDMI Audio. 
When a digital input is assigned, the unit checks for the presence of 
a digital signal at that input. If a digital signal is present when the 
source is selected, it is automatically activated and the proper surround 
mode enabled. If no digital signal is present, the analog inputs for that 
source are selected. This auto-sensing is the preferred configuration for 
digital source inputs such as DVD players. When an ANALOG input is 
assigned, the unit will not access a digital signal, even though one may 
be available at the digital input.
By default, the source input buttons are factory configured to select the 
following inputs:
 CD: 
Digital Coaxial 2
Tuner:
Analog
Tape:
Digital Coaxial 3
Video 1:
HDMI Audio (HDMI 1)
Video 2:
HDMI Audio (HDMI 2)
Video 3:
Digital Optical 1
Video 4:
Digital Optical 2
Video 5:
Digital Coaxial 1
Each source input should be configured using the ON-SCREEN DISPLAY 
menu system to use the desired input type (analog or digital auto-
sensing). See the INPUT MENU section for configuration instructions.
Note: In addition to selecting analog or digital signals, the
configuration options also permit custom labeling and selection of
a default surround mode for each of the eight inputs.
The input source buttons can also be used with the SEL button (described 
in the next section) to select an analog input source signal to be available 
at the outputs for recording, or for any of the remote zones.

(“RECORD” appears in the front panel display). Then, press and hold 
one of the DEVICE/INPUT buttons within 10 seconds.
Alternatively, you can press the REC button and then use the +/– buttons 
to scroll through the available source options. Select any input (CD, 
TUNER, TAPE, or VIDEO 1–5). Selecting the SOURCE option links the 
recording source to the input selected for main room listening. Whatever 
input is selected for listening is also sent to the record outputs.
To select a source for Zone 2, 3 or 4:
Press the REC button two or
more times to select a zone. Then, press and hold one of the DEVICE/
INPUT buttons within 10 seconds.
Alternatively, you can press the REC button to select a zone and then 
use the +/– buttons to scroll through the available source options. Select 
any input (CD, TUNER, TAPE, or VIDEO 1–5). Selecting the SOURCE 
option links the Zone 2, 3 or 4 source to the input selected for main room 
listening. Whatever input is selected for the main room is also sent to the 
remote zone outputs.
Note: The RR-1061 remote control can be set to send individual
IR commands for each zone. Please refer to the setup manual
supplied with the RR-1061 to program this function.
Party Mode: Selecting the Same Input for all Outputs
0-DM
You may wish to have the same input for listening, recording, and all of 
the remote zones. The RSP-1570 makes this configuration (called Party 
Mode) easy by linking the inputs for recording and remote zones to the 
input selected for listening. When linked, changing the input selection for 
listening will automatically change the input for recording and remote 
zones.
To activate Party Mode,
press and hold the ZONE button on the front
panel or Remote for at least 3 seconds. The words PARTY ON appear 
briefly in the display and the ZONE icon flashes for 10 seconds. The 
record input selection and all remote zone input selections will be 
displayed as “SOURCE”, indicating that they are linked to the input 
selected for listening. While in Party Mode, a “P” indicator remains in 
the front-panel display. 
To cancel Party Mode,
press and hold the SEL button on the front panel
or the REC button on the remote for at least 3 seconds. Party Mode is 
cancelled as indicated by the temporary display of the words PARTY 
OFF in the front-panel display. The recording input and the inputs for all 
remote zones revert to their last previous selection, no longer linked to 
the listening input.
You can also cancel the link for just the record output or for one 
individual zone by selecting a different input for that output. In this case, 
the input selection for the unchanged record output or remote zones 
remained linked to the listening input selection. Any source change 
cancels the “P” indicator in the display.
Selecting Digital Inputs
Q
A default digital audio input can be specified for each source input using 
the Input Setup menu. However, you can override the default digital input 
for the currently selected source by pressing the D-SLT button on the 
remote. Each press of the button steps to the next digital input in order: 
OPTICAL 1, OPTICAL 2, OPTICAL 3, OPTICAL 4, COAXIAL 1, COAXIAL 
2, COAXIAL 3. The actual choices you see will be limited to those inputs 
with an active digital signal connected, so you may not see all of the 
inputs listed.
Overview of 
Surround Formats
To get the best performance from your unit, it helps to understand the 
many surround sound formats available today, to know which decoding 
process to use for a particular recording, and how to select it. This 
section provides basic background information about surround sound 
formats. The following sections provide detailed operating instructions for 
automatic and manual selection of surround modes.
Dolby Surround
Dolby Pro Logic II
The most widely available surround sound format for consumer audio/
video is Dolby Surround®, available on nearly all commercial VHS 
tapes, many television broadcasts, and most DVDs. Dolby Surround is 
the consumer version of the analog Dolby Stereo system first introduced 
in the film industry in 1972. It is a matrix-encoding system that records 
front left, front center, front right, and a mono surround channel into 
a 2-channel stereo recording. During playback, a Dolby Pro Logic® 
or Pro Logic II decoder extracts each channel and distributes it to the 
appropriate speakers.
The original Dolby Pro Logic decoder delivered a mono signal with 
reduced high-frequency content to the surround speakers. A more 
advanced decoder in the processor, Dolby Pro Logic II, increases 
the separation and frequency response of the surround channels for 
significantly improved performance with Dolby Surround encoded 
recordings.
Dolby Pro Logic II decoding should be used for any analog recording 
labeled “Dolby Surround” or any Dolby Digital 2.0 soundtrack. 
Dolby Pro Logic II does a superb job deriving surround sound from 
conventional 2-channel stereo recordings, using phase relationships 
to extract front, right, center, and surround channels. A “music mode” 
makes Pro Logic II an excellent choice for audio CDs.
Dolby Digital
In 1992, a digital recording system, called Dolby Digital, was first 
used in the film industry. Dolby Digital is a recording/playback system 
that uses compression techniques to store large amounts of audio data 
efficiently, much like the JPEG format stores large photographs in small 
files on a computer. Because it is capable of performance beyond that 
of audio CDs and can tailor its output for a wide ranges of system 
configurations, Dolby Digital is the standard audio format for DVDs and 
for digital television broadcasting in the United States.
The Dolby Digital system can be used to record up to six discrete audio 
channels, but can also be used for fewer. For example, a Dolby Digital 
2.0 soundtrack is a digital 2-channel recording of a matrix encoded 
Dolby Surround soundtrack. To play a Dolby Digital 2.0 recording, use 
Dolby Pro Logic II decoding as previously described.
The most common use of Dolby Digital in newer films, in both the film 
industry and in home theater, is Dolby Digital 5.1. Instead of encoding 
multiple surround channels on a two-channel recording, Dolby Digital 
5.1 records six discrete channels: front left, front center, front right, 
surround left, surround right, and a Low Frequency Effects (LFE) channel 
containing ultra-low bass signals intended for a subwoofer. A Dolby 
Digital decoder extracts the channels from the digital bitstream, converts 
them to analog signals and routes them to the appropriate amplifiers 
and speakers. All channels provide full frequency response with total 
separation between all channels and large dynamic range capability. 
A Dolby Digital 5.1 soundtrack can provide more impressive surround 
sound than matrix Dolby Surround.
Decoding of Dolby Digital 5.1 soundtracks is automatic. When the 
RSP-1570 detects a Dolby 5.1 signal on one of its digital inputs, it 
activates the proper processing. Keep in mind that Dolby Digital is only 
available from digital sources (a DVD, a LaserDisc, or a Digital TV/
Cable/SAT tuner). Also, you must connect the source with a digital cable 
(coax or optical) to an active digital input on the processor.
