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.

7.1 Preamp out

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.

Power amplifier

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.
