DACS CALIBRATION

SETUP SPEAKERS LEVELS CALIBRATION DACS CALIBRATION

Selecting the LEVELS CALIBRATION menu DACS CALIBRATION option opens the SPEAKER LEVEL ADJUST menu shown on

page 3-42, which manually calibrates the output levels.

DACS CALIBRATION requires an external noise source. In JBL Synthesis systems, this source is the JBL Digital Acoustical

Calibration System (DACS®). However, an alternate source such as an audio calibration disc can also be used. When the noise test is conducted, the SDP-40HD 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 DACS CALIBRATION 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 DACS CALIBRATION test is finished, the listening mode returns to its custom condition.

Note:

When the DACS CALIBRATION test begins, the SDP-40HD automatically sets the 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 DACS calibration:

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 3-42 displays.

4. Begin playback of the external calibration source and press the or arrow button to select the output level that achieves the SPL Meter reading specified in the external calibration

source instructions.

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.
