If you have the six-channel analog output of the Toshiba connected to the six-channel analog input of the Pioneer, then you should be getting nothing but volume control and amplification at the Pioneer -- no bass management or other signal manipulation. Placing the ICBM between the Toshiba and Pioneer will provide you with some valuable bass management control (it is exactly the application for which the ICBM was developed). Also, the ICBM does include a trim control for the subwoofer, although that is secondary to providing bass management to insure that your speakers get a frequency range they can reproduce well (which you can select as everything above 40Hz, 60Hz, 80Hz, 100Hz, or 120Hz) and that the remaining material be passed to the sub rather than being lost. Basically, your case is very well suited to adding an ICBM.
