Where it fits

Stereo in.
An ambience path out.

The GP-AMBDEC provides a dedicated analog ambience-decoding role. It works with a stereo line signal and feeds a rear-channel amplifier path.

  1. Stereo line signal
  2. GP-AMBDEC
  3. Rear-channel amplifier

The rear amplifier then drives compatible rear speakers. This is analog ambience extraction; it is not a Dolby or DTS digital surround decoder.

The resulting ambience depends on the stereo information in the recording.

Control placement

Decide whether you want a separate decoder or the broader GP-2000 control arrangement.

A few useful answers

Make an informed
connection.

Is this the same as digital surround sound?

No. This is analog difference decoding from stereo, rather than decoding a discrete Dolby or DTS surround soundtrack.

Does the decoder power rear speakers?

The proposed connection includes a separate rear-channel amplifier. Match the amplifier and speakers as part of the complete system.

Can I hear the full setup through the browser panel?

The listening panel is an interactive browser illustration. It does not reproduce a physical five-channel listening room.
