EXTERNAL NOISE TEST

SETUP SPEAKERS MANUAL LEVELS CALIBRATION EXTERNAL NOISE TEST

Selecting the LEVELS CALIBRATION menu EXTERNAL NOISE TEST option opens the SPEAKER LEVEL ADJUST menu shown on page 3-54, which manually calibrates output levels.

The external noise test requires an external calibration source such as an audio calibration disc. When the external noise test is conducted, the MC-12 activates a listening mode based on the current Main Zone input source. Refer to the table below for more information about external noise test listening mode activation.

When a listening mode is activated during the external noise test, all custom listening mode menu parameter settings are ignored. The listening mode is applied to the current Main Zone input source in its factory-default condition. When the external noise test is finished, the listening mode returns to its custom condition.

INPUT SOURCE	LISTENING MODE
2-Channel	PLII MOVIE,	PLIIx MOVIE*
Dolby Digital	DIGITAL**
DTS(-ES)	*
5.1-Channel Analog	5.1a STANDARD

*These listening modes depend on the speaker configuration. Dolby Pro Logic IIx MOVIE will only load when side and rear speakers are present.

**These listening mode names differ depending on the current input source, speaker setup, and parameter settings. Refer to the Listening Mode Descriptions section beginning on page 5-5for more information.

Note:

When the external 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 external noise test:

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

2.Place the SPL Meter at the primary listening position.

3. Press the	or	arrow button to highlight the output level
parameter you want. Then, press the			button to select this
output level parameter.

The horizontal bar graph shown on page 3-54 displays.

4. Begin playback of the external calibration source and press the or arrow button to select the output level that achieves a

75dB SPL Meter reading.

5. After selecting the output level, press the	arrow button to
close the horizontal bar graph.

6.Repeat steps 2, 3, and 4 until you have set all the output levels you want.
