INTERNAL NOISE TEST

SETUP SPEAKERS MANUAL LEVELS CALIBRATION INTERNAL NOISE TEST

Opens the INTERNAL NOISE message shown on the previous page, which indicates that the internal noise test generates loud calibration noise signals.

When the INTERNAL NOISE message opens:

Press the

arrow button to open the SPEAKER LEVEL ADJUST

 

menu shown on the previous page. When the SPEAKER LEVEL

 

ADJUST menu opens, the internal noise test automatically

 

begins.

 

Press the

button to skip the internal noise test.

During the internal noise test, the MC-12 sends calibration noise signals to each speaker in the order shown on the SPEAKER LEVEL ADJUST menu. The cursor automatically scrolls through output level parameters, highlighting each parameter as the MC-12 sends the calibration noise signal to the corresponding speaker. The calibration noise signal is sent to each speaker for about 4 seconds.

Note:

When the internal noise test begins, the MC-12 automatically sets volume level to +0dB. Avoid adjusting the master volume level while the test is in progress to achieve THX reference levels (75dB).

To manually calibrate output levels during the internal noise test:

1. Set the SPL meter to “C” weighting and “SLOW” response.

2. Press the

or

arrow button to highlight

the desired

output level parameter. Then, quickly press the

button to

select this output level parameter. The horizontal bar graph shown on the previous page will open on the on-screen display and automatic scrolling will stop.

Note:

During the internal noise test, it is possible to select an output level parameter just as the cursor is about to automatically scroll to the next parameter, causing the MC-12 to send the calibration noise signal to both speakers. If this occurs, reselect the desired speaker.

3.

When

the horizontal bar graph opens, press the

or

 

button to select the output level that achieves a 75dB SPL

 

meter reading from the primary listening position.

 

4.

Press

to close the parameter. The internal noise test will

continue and automatic scrolling will resume.

5.Repeat steps 2, 3, and 4 until all desired output levels have been set.
