Bi-AmpLIFIED SYSTEMS
The most common application of
The HD600/4 can be configured to drive a
Bi-Amplified System with one HD600/4
In this configuration, the “Rear” channels of the HD600/4 will drive subwoofers (stereo 150W x 2 or bridged 300W x 1) with
Crossover Setup for Bi-Amplified System with one HD600/4:
Once the input sections have been configured appropriately, go to the “Rear Channel Controls” Section. Select “LP”
Next, turn your attention to the “Front Channel Controls” Section. and select “HP”
After proper adjustment of the Front and Rear channel “Input Range” and “Input Sens.” controls using the method shown in Appendix C (pages 18, 19), you can fine tune filter frequencies and slopes and attenuate either pair of channels to achieve proper balance. For precise filter frequency information refer to Appendix B (page 18).
This configuration requires that the separate subwoofer amplifier has a
The separate subwoofer amplifier will drive the subwoofer system with
filter frequency of 80-90 Hz to start). The inputs
of the subwoofer amplifier can be fed from the
HD600/4’s preamp output or from a dedicated subwoofer output on the source unit.

Once the input and preamp output sections have been configured appropriately, go to the “Front Channel Controls” Section. Select “HP”
Next, turn your attention to the “Rear Channel Controls” Section and select “HP”
After proper adjustment of the HD600/4’s and the subwoofer amplifier’s “Input Range” and “Input Sens.”, you can fine tune filter frequencies and slopes and attenuate either pair of channels to achieve proper balance. For proper adjustment of the “Input Sens.” controls of the HD600/4 use the method shown in Appendix C (pages 18, 19). For precise filter frequency information for the HD600/4 refer to Appendix B (pages 18). Refer to the subwoofer amplifier owner’s manual for its proper adjustment levels.

1)“Front”: The preamp output delivers the same signal that is connected to the HD600/4’s
“Front Inputs”. This mode is useful for feeding a subwoofer amplifier when the
HD600/4 is being used to drive front and rear speaker systems. In this mode, the preamp output level will track with the signal level of the front input signals, allowing the user to fade the rear channels in and out, without affecting the subwoofer level.
3)“F+R” (Front + Rear): This mode delivers a sum of the signals being fed to the “Front Inputs” and the “Rear Inputs” of the amplifier. When the HD600/4 is being used to drive front and rear speaker systems, this preamp output mode will deliver a summed front/rear signal to the subwoofer amplifier, while permitting fading of the front and rear speaker systems from the source unit.
