Bi-Amp and Tri-Amp configurations can be supported. In these cases, the outputs shown all would have the same inputs duplicated on two and three pairs of outputs. The center output AUX C would have the R Main selected. Each channel of output has an independent trim volume and is adjusted using the master volume control.

If separate subs are used with a stereo system we can make both stereo and mono subs. The low pass filters can be implemented which have a 3 dB point at about 120 Hz. Notice that the AUX C channel is made by mixing the R and L front channels. This sum results in a higher level signal. The 6 db cut feature is implemented with a jumper which reduces the combined level to a level equivalent with the others.

Home theater applications are equally flexible. The basic 6 channels are provided and the extra two can be used for extra subs, center, or sides.

Bass management is always one of the biggest challenges with a home theater system. If the subs are only attached to the sub channel, no bass is heard when a CD is played. The Player allows bass from multiple sources to be blended. In the following case the sub channel is derived from the sub input as well as the bass from both front channels. The AUX outputs are stereo subs from the front R and L blended with the extra sub channel. The mix balance is set using the L and R main trim pot next to the switches.
