speaker settings easily, quickly and systematically without
troublesome adjustments.
To obtain the best possible sound effect from the Surround/
DSP modes, set up the speaker and subwoofer information
after all the connections are completed.

Setup
7 Before starting Precise Surround Setup
• Connect all of your speakers and subwoofer correctly and
confirm their position.
• When subwoofer has a built-in volume and crossover
frequency controls, adjust them as follows:
– Set the volume level to the medium.
– Set the crossover frequency to the highest level.
• Precise Surround Setup is not available in the following
cases:
– While headphones are connected
– When selecting “A MULTI” for the audio input setting (see
page 11)
– When multi-channel PCM signals (see page 41) are coming
in with selecting “HDMI” for the audio input setting (see
page 11)
• Do not block between the earphone-type microphones and
speakers while the microphones are picking up test tones
from the speakers.
• If the microphone cord is not long enough to make a
connection between the receiver and your listening
position, use a stereo extension cord (not supplied).
– You cannot get correct results with a monaural extension
cord.
CAUTION:
Be sure that loud test tones will be generated from
speakers during Precise Surround Setup.
• The volume of test tones is not adjustable.
