By using Precise Surround Setup, you can optimize the
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.
Setting the speakers automatically
Precise Surround Setup detects the sound from the speakers
to measure your listening environment with dedicated
earphone-type microphones (supplied), and automatically
adjusts the following in less than 1 minute:
• Speaker size*
• Speaker distance*
• Speaker output level*
• Crossover frequency*
• Frequency response
Precise Surround
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.
