Anthem AVM 50v 3D - Manual (Page 39)

If SUBS is set to Super in BASS MANAGEMENT-MOVIE (not advised) or BASS MANAGEMENT-MUSIC, do
not rely on an SPL meter to set subwoofer level – set it by ear while playing various sources. Level Calibration
cannot take into account the bass that’s added to the subwoofer from speakers set to Large, which results
in more bass during playback than the calibrated level.
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. 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 (turn off main amplifiers), 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.
Procedure for Manual Test Sequence (not needed when using ARC):
• Enter the setup menu. Go to LEVEL CALIBRATION and press SELECT.
• Use the 34 buttons to 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 BACK to stop the test noise.
Procedure for Auto Test Sequence (not needed when using ARC):
• Enter the setup menu. Go to LEVEL CALIBRATION and press SELECT.
• Use the 34 buttons to set NOISE SEQUENCE to Auto.
• Press SELECT to start the automatic sequence.
• As each speaker plays, use the 34 buttons to adjust its loudness relative to other speakers. After
you make an adjustment, the next speaker will play.
• Press BACK to stop the test noise.
