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
amplification.
