Note: The test tones may be loud. Be prepared before starting the Full or
Semi Autocal procedures.
The Far Field test sets the speaker distances, crossover points and
output levels. The microphone is stationed in the center of the
preferred listening area and a test tone is sent to each speaker.
Note: If the Far Field test is skipped, the Near Field test must also be
skipped.
The Near Field test adjusts the AV2, performing system equalization
to compensate for speaker performance and placement. The
procedure seeks to give the system a consistent tonal balance
between the front left, front right, center, side left, side right, rear left
and rear right speakers, if applicable. The test calibrates each speaker
separately, and the user individually selects each speaker to calibrate.
The microphone should be held within two feet of the speaker baffle
as a test tone is sent to the speaker.
The Subwoofer test is done in two parts. The user is instructed to
hold the microphone to the left of the primary listening position and
then to the right of the primary listening position. Two test tones are
sent out to all connected subwoofers during each of the two test
phases. Two tones are sent to ensure that subwoofers with auto
power settings are active during the procedure.
Note: If there are no subwoofers in the system, then this test will not pass
and must be skipped.
Note: If the system includes the JBL BassQ subwoofer room mode
corrector, the BassQ parameter in the AV2 setup must be set to Yes and
the BassQ procedure must be performed BEFORE running the AUTOCAL
procedure. In this case, the subwoofer section of the AUTOCAL is
automatically skipped as the BassQ procedure is more accurate for
subwoofers.
For optimum results, all noise generators in the room should be
removed before performing the Full or Semi Autocal procedure.
However, air conditioners and similar steady-state background noise
should have minimum impact on the test and can be left on.
When the procedure is complete, the user will be prompted to save
the settings. These settings can be saved in one of three Preset
locations. See
Section 4: Audio Controls and Video Status for more
information on the Preset locations.
Note: When calibration is complete, the volume level is set to a relatively
high level. Before playing an audio track, be sure to turn the volume down
to avoid potentially damaging volume levels.
