JBL Synthesis

Internal Noise Test (continued from page 3-39)

Note:

The SDP-5 automatically sets volume level to +0dB when the internal noise test begins. It is recommended to avoid adjusting master volume level while the test is in progress to achieve a 75dB THX reference level (a 75dB SPL meter reading).

When the internal noise test is conducted, a calibration test signal travels to the Main Zone audio output connectors in the order listed on the SPEAKER LEVEL ADJUST menu. As the calibration test signal travels, the cursor automatically scrolls downward through SPEAKER LEVEL ADJUST menu parameters, highlighting each speaker parameter as the corresponding output connector is tested. Each output connector is tested for about 4 seconds.

The SPEAKER LEVEL ADJUST menu can be used to manually adjust output levels while the internal noise test is conducted. Refer to page 3-42 for more information.

Please note the following:

•When the internal noise test is conducted, it is possible to select a SPEAKER LEVEL ADJUST menu parameter just as the SDP-5 is about to automatically scroll to the next parameter, causing the SDP-5 to send the calibration noise to both speakers. If this occurs, reselect the desired speaker.

Note:

Main Zone audio output connectors for which the corresponding CUSTOM or SYNTHESIS 7CH SETUP menu parameter is set to NONE cannot be adjusted during the internal noise test. These output connectors can be adjusted during the external noise test, but there is no need to do so.
