FULL AUTOCAL
Selects the FULL AUTOCAL procedure, which automatically sets the
speaker distances, crossover points and output levels, as well as
performing system equalization adjustments.
Note: The Full or Semi Autocal settings that are saved to the Preset
locations include the system equalization adjustment values. However,
even if the Auto EQ setting is Active, the autocal settings for the system EQ
do NOT apply to certain high-bit-rate incoming data streams, such as
176kHz and 192kHz PCM.
Performing the AUTOCAL Procedure:
Before beginning the AUTOCAL procedure, set the AV2 to an input
that does not have a currently active source.
There should NOT be
an active audio track playing when the AUTOCAL procedure
is started.
Note: If the system includes the JBL BassQ subwoofer room mode
corrector, you must enable the BassQ parameter in the AV2 Setup menu
and run the JBL BassQ procedure BEFORE running the AUTOCAL
procedure. Activating the BassQ parameter optimizes the delay and
Autocal settings for use with the JBL BassQ system.
After running the JBL BassQ procedure, you must set the subwoofer
output level (the AUTOCAL procedure skips over the Subwoofer test as
the BassQ procedure is more accurate for subwoofers) and then you can
run the AUTOCAL procedure.
If the AUTOCAL procedure has already been run, set the Auto EQ
parameter to Off and then run the JBL BassQ procedure. The AUTOCAL
procedure must be run again AFTER the JBL BassQ procedure is complete.
Ensure that the JBL BassQ parameter is set to “Yes” BEFORE running
either procedure.
In order to perform this test, the following initial setup is required:
•
All of the speakers are connected to the AV2 and positioned in
the listening space.
•
A monitor is connected to the AV2 for viewing the OSD during
the procedure.
•
The microphone, included with the AV2, must be connected to
the rear panel microphone input connector and positioned in
the primary listening position.
Note: For best results, install the microphone onto the accompanying
rod by threading the two parts together and hold or place it in the
primary listening position. Use a microphone stand or tripod if
necessary.
CAUTION!
DO NOT place the microphone too close to the speakers
during the autocal procedure. If the microphone is within
one foot of the speaker, the test tones that are output
during the autocal procedure could cause a feedback loop
t h a t m a y d a m a g e t h e s p e a k e r. We a s s u m e n o
responsibility for speaker damage.
The Full Autocal procedure is comprised of three parts: the Far Field
Test, the Near Field Test and the Subwoofer Test. Each part provides
directions on the OSD at the start of the test, for volume level and
microphone positioning, and each test sends test tones to the
speakers.
Note: Before activating the calibration, ensure that the AV2 is NOT muted.
If Mute is active, then the test-tone calibrations will not be accurate.
For the Far Field test, the test tones sent to each speaker follow a
specific order. The order of testing is Front Left, Front Right, Center,
Side Left, Side Right, Rear Left and Rear Right.
