DACS CALIBRATION

Selecting DACS CALIBRATION accesses the SPEAKER LEVEL ADJUST menu (pictured on page 3-36).

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. As the noise test is conducted, the SDP-40 loads the DOLBY Pro Logic II, Dolby Digital, or dts(-ES) utilizing the signal from the DACS® calibration system or audio calibration disc.

when DACS CALIBRATION is conducted, the unit will activate the DOLBY Pro Logic II listening mode. If a Dolby Digital input type is coming in, the unit will activate the DOLBY DIGITAL listening mode. And if a dts(-ES) input type is coming in, the unit will acti- vate the dts(-ES) listening mode. When DACS CALIBRATION is selected, these listening modes will retain their factory-default settings. The unit will temporarily disregard customized listening mode settings.

For system optimization using DACS® and a JBL Synthesis Digital Equalizer, connect the left and right RCA outputs of the DACS® signal generator (EVP-1) to the #1 analog input (which is active in the TAPE input) and set the front panel volume level to 0dB. This will provide the correct signal path and reference output level.

Before making adjustments, set the SPL meter according to the DACS® Installers Manual or audio calibration disc instructions. If no setting is recommended, set the SPL meter to “C” weighting and “SLOW” response. Use the up and down MENU arrows to manually scroll through menu items. Press the right MENU arrow to select an output for adjustment, then use the up and down MENU arrows to increase and decrease the level of the selected output in 0.5dB increments within a range of -18 to +12dB. Adjust all output levels to achieve the appropriate reading on the SPL meter from the primary listening position. Press the left MENU arrow to exit the selected output and return to the SPEAKER LEVEL ADJUST menu.

Note:

SDP-40 Balanced output levels must be recalibrated when output connections are changed from unbalanced to balanced or vice versa. The balanced outputs are approximately 6dB louder than the unbalanced outputs.
