Optimizing the speaker setting for your listening room
24 En
This unit employs the YPAO (Yamaha Parametric Room Acoustic Optimizer) technology which lets you avoid
troublesome listening-based speaker setup and achieves highly accurate sound adjustments automatically. The supplied
optimizer microphone collects and this unit analyzes the sound your speakers produce in your actual listening
environment.
• Be advised that it is normal for loud test tones to be output
during the “AUTO SETUP” procedure.
• To achieve the best results, make sure the room is as quiet as
possible while the “AUTO SETUP” procedure is in progress. If
there is too much ambient noise, the results may not be
satisfactory.

You can run “AUTO SETUP” using the system menu that appears
in the OSD or in the front panel display. This manual uses the
OSD illustrations to explain the “AUTO SETUP” procedure.
