Calibrating the system

Choose the position in which the subwoofer reinforces the sound from the main speakers in the crossover region.

You should not adjust the delay as this has already been specified when you time-aligned the layout.

Other subwoofers

●Press Store to adjust any additional subwoofers in the system in exactly the same way. In each case adjust the phase for maximum reinforcement.

●Use ] and [ to step between the subwoofers.

In the case of other configurations you will be balancing different combinations, in some cases the best test is that multiple subwoofers reinforce each other or the bass from wideband speakers like the main left and right (if applicable).

The table opposite lists the combinations and adjustments you may make for the different Layout options; see Specifying the speaker layout, page 22.
