JL Audio XD600/6 owner manual One pair of stereo outputs and dedicated subwoofer outputs

D)Subwoofer Level Control Only: Required: a source unit or processor with

one pair of stereo outputs and dedicated subwoofer outputs.

Input Connections: the stereo pair of source unit outputs each split with a “Y-Adaptor” allowing the left signal to be sent to the “CH 1 (Left)” and “CH 3 (Left)” inputs and the right signal to be sent to the “CH 2 (Right)” and “CH 4 (Right)” inputs of the XD600/6. The source unit’s dedicated subwoofer outputs are connected to the “CH 5 (Left)” and

“CH 6 (Right)” inputs (select “6 Ch.” on the “Input Mode” switch in the “Channel 5 & 6 Controls” section).

Result: in this mode, the user has the ability to control the absolute level of the LF channels relative to the HF channels.

E)Independent level control of all three channel pairs:

Required: a source unit or processor with two pairs of stereo outputs and dedicated subwoofer outputs.

Input Connections: one pair of stereo source unit outputs is connected to the “CH 1 (Left)” and “CH 2 (Right)” inputs, the second pair of stereo source unit outputs is connected to the “CH 3 (Left)” and “CH 4 (Right)” inputs and the source unit’s dedicated subwoofer output is connected to the “CH 5 (Left)” and “CH 6 (Right)” inputs (select “6 Ch.” on the “Input Mode” switch.

Result: in this mode, the user has the ability to control the absolute level of the LF channels as well as both pairs of HF channels.

When using a source unit’s dedicated subwoofer output, set the “Input Sens.” of any channels receiving input from the subwoofer output with the source unit’s subwoofer level control set at 3/4 of full output. See Appendix A (page 14) for details.

Crossover Setup for Bi-Amplified System with one XD600/6:

Once the input sections have been configured appropriately, go to the “Channel 5 & 6 Controls”. Select “LP” (low-pass) on the “Filter Mode” switch and an appropriate “Filter Freq.” (80 Hz is a good starting point).

Next, turn your attention to the “Channel 1 &

2 Controls” and “Channel 3 & 4 Controls” and select “HP” (high-pass) on the “Filter Mode” switches and an appropriate “Filter Freq.” (again, 80 Hz is a good starting point).

After proper adjustment of the “Input Sens.” controls for all three channel pairs using the method shown in Appendix A (page 14), you can fine tune filter frequencies and attenuate any pair of channels to achieve proper balance. For precise filter frequency information refer to Appendix B (page 15).
