Volume (GAIN)

With the GAIN control you can adjust the relative volume level of the subwoofer to the main speakers of the system:

Play the same track a couple of times, adjusting the level so that the instrument sounds homogenous across its range.

If you find that at certain specific bass tones the response is either too loud (bloated sound) or soft (thin sound), it may be that you have to experiment further with the location of the subwoofer and/or the cross-over settings.

Refer to the sections “Positioning the subwoofer” on page 20 and “Cut-off frequencies” on page 25 for further information.

Note: When using multiple subwoofers, ensure that the settings for cut-off frequency, phase and LF extension are identical. Use the LFE and Slave mode options to ensure that all subwoofers operate on the same settings (refer to chapter “Multiple subwoofer connections” on page 13).

Different acoustic loadings can be found within a listening room. Thus, balancing out modes may require different power levels.

Cut-off frequencies

Matching the frequency responses of subwoofer and speakers has an important impact on the overall sound quality, when integrating a subwoofer into a audio-video-system. In general a large, floor-standing speaker still has significant output in the deeper bass range, whereas a very small speaker will not be able to reproduce deep bass at all. In the first case a bump in the overlapping area will cause a louder or even bloated sound while in the second case an acoustic hole will be experienced.

The following figures visualize the possible results (please note that all curves are for illustration purposes and do not show exact filter characteristics).
