The MA7900 can be part of a Multichannel Sound

System for SACD, DVD-Audio and Home Theater.

The Right and Left Front Channels from an Audio/

Video Control Center or Surround Decoder can

“Passthru” the Preamplifier Circuitry of the MA7900,

and then on to the Power Amplifier Circuitry of the

MA7900. The Setup Mode allows the activation of

the Passthru Mode and the selection of the speci-

fied MA7900 Input Source. In the example below,

the Right and Left Front Channels from the Audio/

Video Control Center will be connected to the SRVR

(Server) Input Jacks on the MA7900. Refer to page 10

Connectors are not assignable as a Passthru

reassigned to a given Input, they will not

appear in the list of available Inputs for the

Passthru Mode.

from the list of available Inputs by switching

it Off. Refer to “Source Inputs Reassignment”
