Protection - T+A R 2500 R User Manual

Compatibility information
Due to the large number of different versions of the HDMI standard, a general compatibility between the
devices cannot be guaranteed. Not all manufacturers implement all functions in the same way. Please
refer to the user manual of the respective device to find out whether the desired function is available.
To use the ARC (Audio Return Channel) function, the TV must support it and the R 2500 R must be connec-
j
ted to an ARC compatible input of the TV.
HDMI Bypass
This function allows you to select whether the audio signal at the HDMI connections
HDMI 1 and HDMI 2 is to be played back by the R 2500 R, or whether it is passed on for
playback by a device connected to the HDMI output.
Switch on the HDMI bypass function if the R 2500 R is connected between the source de-
j
vice and the television / surround amplifier, and you wish to play back the sound through
the television or surround amplifier.
Playback
Since the R 2500 R is designed for pure stereo playback, only 2-channel PCM or DSD64/DSD128 enco-
ded material can be played back via the HDMI inputs of the R 2500 R. For playback via the R 2500 R, the
configuration of the HDMI output at the source device may need to be changed. Set the HDMI output to
PCM output and activate DSD playback via HDMI if available. Always select the stereo track in the menu
of the inserted disc.
If you wish to play back a disc in surround format (e.g. Dolby Digital or DTS) via the television or a sur-
round amplifier, the sound can be passed on from the R 2500 R to that unit (see HDMI Bypass settings).

Protection

The Protection circuit protects the R 2500 R from damage caused by short-circuit, overheating and over-
loading. If a problem occurs, the protection circuit switches the output signal off, the loudspeaker output
buttons start to flash, and the screen displays one of the following messages:
Overheat indicates that the amplifier has become too hot. If this should occur, the machine should be left
switched off for a generous period in order to cool down. Ensure that there is an adequate flow of cooling
air to and from the machine. It will not be possible to switch the machine on again until it has cooled down
to the appropriate temperature.
Clipping appears if the volume is set too high, causing distortion at the loudspeaker output. The R 2500 R
detects this automatically, and reduces the volume accordingly.
Short R means the right-hand loudspeaker output is short-circuited. If this should happen, please check
the loudspeaker cables.
Short L means left-hand loudspeaker output is short-circuited. If this should happen, please check the
loudspeaker cables.
If you find it impossible to solve a problem with the help of these notes please disconnect the unit from the
j
mains and ask your authorised T+A specialist dealer for advice.
