2.2 AUDIO CONNECTIONS
AUDIO INPUTS AND OUTPUTS
Digital audio sources can be connected using an HDMI, coaxial or optical cable. These
connections carry linear PCM, Dolby Digital, and DTS audio formats. HDMI connection
is generally preferred to ensure that lossless audio is used where sources provide it
although optical/coax can also be used for sources outputting 2-channel PCM, Dolby
Digital 5.1, and DTS 5.1 without affecting audio quality.
Audio on the HDMI outputs is 2-channel PCM as this is meant for the TV’s use.
HDMI AUDIO RETURN CHANNEL
If the TV provides audio through HDMI ARC, for example when it accesses streaming
media sources, it can send the audio to the MRX through HDMI output 1, eliminating the
need for a separate audio connection. CEC control, described in a later section, must be
enabled for Audio Return Channel to function.
If the display reads “Dial Norm Offset -4.0 dB” at the start of a movie, it is indicating that
the encoded level is higher than standard by 4.0 dB – the playback level of all channels is
then automatically reduced by 4 dB.
PREAMP OUTPUTS
The pre-outs are variable according to the volume control and can be used with external
amplication.
