• Check that the proper video source is selected for each input.
• Check that the group delay (lip-synch) setting is not misadjusted.
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.
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
in to reset.
No video from Zones 2, 3 or 4
• Check ZONE SETUP configuration and zone video input setting as
assigned and make sure that a Composite 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.
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 1.3 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 receiver is able to decode and replay these 7.1
channel audio formats.
Also with Blu-ray, but depending on the monitor being used to view the
picture, you may also be able to enjoy new video enhancements such
as Deep Color or XY video (also called Broad Color Space). Using the
HDMI 1.3 connection, this receiver 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.
Can I connect components which have earlier versions of
HDMI?
Yes, because HDMI is backwards-compatible. This means that
components which have earlier versions of HDMI (such as HDMI 1.1 or
HDMI 1.2) will perform correctly when connected to the HDMI 1.3 inputs
or outputs of the receiver.
If your DVD player is equipped with HDMI 1.2a, the HDMI connection
will permit the transmission of 1080p (high definition) video signals.
Which is the best way to rescale the picture?
When using legacy components that require picture rescaling, it is better
to use the monitor scaler to handle any picture resizing. You should try to
use only one scaler in the system, so keep your DVD player set to 480p
or 1080p. A 480p signal will be rescaled by the monitor and a 1080p
signal will be seen by a monitor with 1080p resolution as a native
signal.
Some Blu-ray and HD-DVD discs have been recorded in 1080i. These
should not be scaled, but are best left to the monitor to interpret into an
appropriate format for the screen.
Will the HDMI digital output improve the picture quality from
old analog sources?
Analog picture sources from legacy units begin by being less good than
digital signals, and while the receiver will translate them into a digital
format, the final quality will be constrained by the original source, and
the choice of connection (Composite, S-Video or Component). The scaler
cannot correct for low resolution signals and will not improve inherently
poor picture quality.
Why does the HDMI connection sometimes not give a picture?
Although it is simple to use, the HDMI connection is actually a highly
complex electrical circuit, and within it is a security system called HDCP
(High Definition Content Protection). In some circumstances pictures
may not reproduce, or may not reproduce properly, due to the action
of DRM (Digital Rights Management) or the ‘handshake’ between
the two connected units. HDMI cables contain circuits that exchange
a ‘handshake’ signal several times a second, designed to maintain
the integrity of the transmission signal and to prevent attempted
unauthorized copying of copyright material. However, these ‘handshake’
signals can be disrupted for several reasons. If problems persist, consult
your Rotel dealer.
