Ch/5Ch/7Ch Stereo Formats - Rotel RSX-1562 Owner's Manual

English
any other source material; however, typically DSP settings would be used
with source material for which there is no specific surround decoder .
The four DSP MODES in the receiver use digital delay and reverberation
effects to simulate progressively larger acoustic environments with DSP 1
being the smallest type of venue (such as a jazz club) and DSP 4 being
a large venue (such as a stadium). Typically used to add ambience and
a sense of space when listening to music sources or other sources that
lack surround sound encoding.

2CH/5CH/7CH stereo formats

The RSX-1562 also provides four modes that disable all surround
processing and deliver stereo signals to amplifiers and speakers. The
four options are:
2CH Stereo: Turns off the center channel and all surround channels in the
system and delivers a conventional 2-channel signal to the front speakers.
If the system is configured to route bass signals from the front speakers
to the subwoofer , this capability remains in effect.
Analog Bypass: For 2-channel analog inputs, there is a special stereo
mode that bypasses ALL of the RSX-1562's digital processing. The two front
speakers receive pure analog stereo full-range signals with no subwoofer
crossover, no delay, no level adjustments, and no parametric eq.
5CH Stereo: Distributes a stereo signal to 5.1 channel systems. The left
channel signal is sent, unchanged, to the front left and surround left
speakers. The right channel is sent to the front right and surround right
speakers. A mono sum of the two channels is sent to the center channel
speaker.
7CH Stereo: This mode is the same as 5CH Stereo described above
except that it also distributes stereo signals to center back speaker(s)
installed in the system.
Other Digital Formats
Several other digital formats are not surround sound formats at all, but
rather systems for digital 2-channel recordings.
PCM 2-channel: This is an uncompressed 2-channel digital signal that is
used for standard CD recordings and some DVD recordings, particularly
of older films.
DTS Music 5.1 Discs: These discs are a variation of audio CDs that
include a DTS 5.1 channel recording. The receiver decodes these disc s
just like a DTS movie soundtrack when played on a CD player or DVD
player with a digital output connection.
DVD-A music discs: Taking advantage of the increased storage capacity
of the DVD disc, new high bit rate multichannel audio recordings are
available on DVD-A discs. DVD-A discs may include multiple versions
of the recording including standard PCM stereo, Dolby Digital 5.1, DTS
5.1, and 96kHz/24 bit (or higher) multi-channel recordings using MLP
compression. Several of these formats (standard PCM, Dolby Digital,
and DTS 5.1) can be decoded by the receiver when the DVD player is
connected with a digital cable. However, the existing optical and coax
digital audio connection standard does not provide sufficient bandwidth
for multichannel high sampling rate MLP recordings. Therefore, you must
use the HDMI high-definition digital connection to replay the high-resolution
audio soundtrack of DVD-A discs. Alternatively, the high-resolution audio
can be decoded by the DVD-A player and the resulting analog signals
sent to the receiver' s MULTI INPUT.
SACD®: This is a proprietary high-resolution audio standard for use on
SACD compatible disc players. As with DVD-A discs, the bandwidth is
too high for today's digital connection. Thus, these discs must be decoded
by a SACD compatible player, with the output sent to the receiver's
MULTI INPUTS.
MP3: MP3 format recordings, often downloaded from the Internet, can
be played on portable MP3 players or some disc players that can read
CD-ROM discs. These players can be connected to the receiver' s digital
inputs, but must output a digital PCM stream.
