To connect external power amplifiers, use Phono/RCA leads connected
to the 7.1 Preamp Outputs on the rear panel.
For 5.1/6.1/7.1 use set the ‘Pre Out’ setting in the ‘Output Setup’ OSD
menu to 'Pre Out' rather than 'Normal'. This mutes all the internal power
amplifiers as they are not being used.
Alternatively the 640R features an External 2-Channel mode. This allows
the 640R to reproduce all the surround channels of suitable source
material (Centre, Surrounds and Sub) whilst the Left and Right Front
speakers are driven by an external power amplifier or other amplifier
capable of supporting fixed level inputs (e.g. Cambridge Audio’s 740A or
840A amplifiers).
Set the ‘Preamp Out’ to ‘Ext 2 Ch’ in the OSD to mute the front left and
right amplifier outputs only:
12
5.1/6.1/7.1 Direct in
DVD-A or SACD players can be connected to the 640R via its 5.1/6.1/7.1
Direct inputs allowing multi-channel music playback from these new
sources.
DVD-A and SACD both support 5.1 output. The 640R's direct inputs also
allow optional connection of Surround Back or Surround Left and
Surround Right signals for compatibility with future 6.1 or 7.1 sources or
external decoders.
To select the Direct Input press the
7.1 Direct
button on the front panel
or remote.
Note: These connections are pure analog for best sound quality and no
DSP processing or Bass and Treble adjustment by the 640R is possible.
