Troubleshooting

Most difficulties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difficulty, check the control settings, determine the cause of the fault
and make the necessary changes. If you are unable to get sound from
the unit, refer to the suggestions for the following conditions:
The unit does not turn on
• Make sure the power cord is plugged into the rear panel and a
AC outlet.
• Make sure the rear panel POWER switch is in the ON position.
No sound from any input
• Make sure that MUTING is off and VOLUME is turned up.
• Make sure that preamp outputs are connected to a power amplifier
and that the amplifier is turned on.
• Make sure source inputs are connected and configured correctly.
• Check that the setting for HDMI AUDIO in the VIDEO/HDMI on-
screen menu is AMP MODE.
No sound from digital sources
• Make sure that digital input connector is assigned to the proper
source input and that the source input is configured to use the digital
input rather than an analog input.
• Check the configuration of the DVD player to ensure that the bitstream
and/or DTS digital output is activated.
No sound from some speakers
• Check all power amp and speaker connections.
• Check Speaker Configuration settings in the Setup menus.
No video output on TV monitor.
• Make sure that the TV monitor is connected properly and check the
input assignments. Composite Video TV monitors can only be used
with interlaced SD sources. HDMI and Component TV monitors
can be used with Standard Definition (SD) and High Definition
(HD) sources. An HDMI 1080p source can only be sent to a
1080p-compliant TV monitor.
• Component Video output at 720p or 1080i may not be available
if the source signal includes HDCP copy protection.
• HDMI cables must be 5 meters or less in length.
• If watching 3D source, make sure the display is 3D enabled.
Video and Audio do not match.
• Check that the proper video source is selected for each input.
• Check that the group delay (lip-synch) setting is not mis-adjusted.
Clicking or popping sounds when switching inputs
• The unit uses relay switching to preserve maximum sound quality.
The mechanical clicking of the relays is normal.
• During switching, it may take a split second for digital signals to
be recognized and properly decoded. Rapid repeated switching
between inputs or settings can result in clicks or pops from the
speakers as the unit attempts to lock on to the rapidly changing
signals. This causes no harm.
• Switching between HDMI sources may cause delays as HDMI two
way communications "handshake" must be established between
the source and display. The time required for the handshake varies
from equipment.
Controls do not operate
• Make sure that fresh batteries are installed in the remote.
• Make sure that the IR sensor on the front panel is not blocked. Aim
the remote at the sensor.
• Make sure the sensor is not receiving strong IR light (sunlight,
halogen lighting, etc.)
• Unplug the unit from the AC outlet, wait 30 seconds, and plug it
back to reset.
No video from ZONE 2, 3 or 4
• Check ZONE SETUP configuration and ZONE video input setting
assigned and make sure that a video source is connected.

HDMI: Frequently Asked Questions

What is HDMI?

HDMI (High-Definition Multimedia Interface) is an advanced type of
connection which carries both video and audio in a single cable. It is a
modern digital replacement for older analog video connection standards
such as Composite Video, S-Video and Component Video. This Rotel unit
meets the latest version of HDMI specification, HDMI 1.3, and HDMI 1.4
with 3D support and Audio Return Channel.

What is the difference between HDMI and DVI?

An earlier digital connection standard, DVI (Digital Visual Interface) can
also be used for high-definition video signals by means of a suitable
adaptor. However, unlike HDMI, the DVI connection does not also
carry audio signals, nor does it automatically set the picture screen to
the correct size.
What is the difference between HDMI 1.4, HDMI 1.3 and earlier
versions?
If you have a Blu-ray player, note that the HDMI 1.3 connection can
carry the new Dolby TrueHD and DTS HD Master Audio formats used
on Blu-ray discs. This processor is able to decode and replay these 7.1
channel audio formats. HDMI 1.4 includes additional features such as
3D video pass through for movies, games and broadcasts.
Also with Blu-ray, but depending on the monitor being used to view the
picture, you may also be able to enjoy video enhancements such as Deep
Color or XY video (also called Broad Color Space). Using the HDMI 1.4
connection, the RSP-1572 can pass these signals through from the Blu-ray
player to a compatible monitor.
These new audio formats and video features are not available from standard
DVD discs or players, even when an HDMI connection is used.
