Test Noise Sequence:
Test noise plays from one speaker at a time, changed by using the
56 buttons.
Level Calibration of each channel:
Balances speaker levels to one another. If you’re calibrating by ear, use the remote control and sit in the
listening area when adjusting. If using an SPL meter, adjust level so it reads 75 dB for each channel. If Noise
Level is set while Front-L is at 0 dB, no adjustment of Front-L is needed since the output is the same. If using
a powered subwoofer, make a rough adjustment with its input level control before setting sub level in this
menu or using ARC. Speakers set to Off in the Bass Management menu are skipped.
If using multiple subwoofers they must be balanced to one another before further audio setup,
including when using ARC. Play the subwoofer test noise with only one subwoofer connected at a time.
Set its input level dial so the SPL meter reads 71 dB from the listening area if using two subs or 67 dB if
using four subs. Repeat this for the remaining subs. When all are connected the result should be around
75 dB. ARC sets the final level for the group of subwoofers. If not using ARC, change the level of all subs
equally for a combined result of 75 dB SPL.
To fine-tune the level or phase of each sub relative to one another, listen to FM “shhhh” noise through
the subwoofers only by disconnecting the receiver’s speaker outputs, and adjust (or better yet have
someone else adjust) the sub’s level and/or phase control until bass is loudest in the listening area. If
your subwoofer has a polarity switch you can instead temporarily invert polarity, adjust according to
lowest bass output (this might be easier to hear than aiming for highest output) and then restore the
switch to the normal position which results in maximum output.
Procedure for Manual Test Sequence (not needed when using ARC):
• Set NOISE SEQUENCE to Manual.
• Press the 56 buttons to go from speaker to speaker.
• As each speaker plays, use the 34 buttons to adjust its loudness relative to other speakers.
• Press 3to stop the test noise.
