If the Surround Speaker are set to None, then the main L •
& R stereo outputs will be standard stereo. In this format,
the left rear channel is added to the main left channel, and
the right rear channel is added to the main right channel.
Left = L + (0.707 x C) + (0.707 x L
s
)
Right = R + (0.707 x C) + (0.707 x R
s
)
Digital audio data in various formats is available at the two
S/PDIF connectors (optical
and coaxial ), the AES/EBU
output and also the dedicated HDMI connector . (See rear
panel connections on page 10.) The data available will depend
on disc type and, in the case of the S/PDIF outputs, also on
the setting of the Digital Output parameter in the Audio tab of
the Setup Menu. The table below summarises the digital audio
outputs for various disc types:

1 The SACD format restricts the output quality of any downmixed output. Therefore, the L

Stereo outputs are limited to 16-bit PCM resolution
when playing SACDs, including the SACD-stereo track. This applies to all digital outputs (S/PDIF, AES/EBU and HDMI), and the stereo analogue
outputs. Therefore when working in stereo, improved analogue quality will be available from the front L/R outputs.

3 May be prohibited by the disc
It can be seen from the table that the S/PDIF outputs will
produce either a downmix of the multichannel audio, or a raw
bitstream for external decoding. This is determined by the
Digital Output setting in the audio submenu; setting this to PCM
will generate the downmix, setting it to Bitstream will generate
the raw encoded audio data alternative. (See page 40 for
further information.)
The AUDIO button
The RC-89’s AUDIO button may be used to select alternative
audio programmes on DVD-V and DVD-A discs that offer them.
Pressing AUDIO scrolls through the available programmes,
which may include different audio encoding systems such as
DolbyDigital®orDTS®,alternativelanguagesora“director’s
commentary”. The inclusion of any alternative audio programme
is determined at the disc authoring stage; many commercial
DVD-V discs do not offer it.
No visual confirmation of which audio programme is currently
selected is given, unless DISPLAY is enabled (see “Time & Other
Displays” on page 25). The data in the Audio field changes
as AUDIO is pressed, indicating the number of the audio
programme, and (typically) the encoding system employed,
number of audio channels available and language.

multichannel audio will be available at both sets of multichannel
analogue audio outputs, and a downmix of this at the main L/R
analogue outputs and the AES/EBU digital output. The output
at the S/PDIF and HDMI digital outputs can be either the same
downmix, or the raw Dolby Digital bitstream; this is determined
by the setting of Digital Output in the audio Setup menu. The
front panel display will show Dolby D when a Dolby audio track is
playing.

same downmix, or the raw DTS bitstream; this is determined
by the setting of Digital Output in the audio Setup menu. A DTS
flag will illuminate in the front panel display when a DTS audio
track is playing.
